Gotcha! Raspberry Pi is now working. The problem is
that you cannot simply copy an .img file to a memory
All this does is move the file just like any other.

Instead, a very special image mapping file such as
Win2imager.exe is required to actually change the
entire image of the memory card.

Note that this program is extremely dangerous
and must be used with extreme care.

Reasonable attempts have been made to verify that
all links work and are largely virus and porn free.

Please report any exceptions. Or suggested additions.

Note that these links can be used with a personal
computer to convert any dumb HDMI television
into a smart tv. At nearly zero cost.

I seem to be getting nowhere trying to boot a Raspberry Pi.

Things learned so far: It would seem best to buy an entire
with a preprogrammed memory card. Boot time
is by no means instant and typically could take 35 seconds
with a class 4 card
. Although 2 Gigs is only needed, at
least 4 Gigs is recommended.

Supply voltage is critical and can be measured from diagonally
opposite pins on the expansion connector. NTSC video may
be less flakey than HDMI. Besides the red power LED,
the activity lights should show activity during and after
booting. Memory cards to be self-loaded probably should
be initialized and removed only with the recommended
eject routine.

Trying to run the checksum routine on Windows 8 is
maddeningly infuriating. I'm working on a PostScript
routine to read the first few thousand program bytes.

Not sure where to go from here. I'll try a new memory
card and then an entire bundled package.

If this happy horseshit is happening to more than one
user in a hundred, the Pi should never have been sold.

"Smart" tv sets are basically an unmitigated disaster.

Their ergonomics are mesmerizingly awful, their
content is both pathetic and second rate, charges
can be outrageous, and attempts at micromanaged
control and DRM are ludicrous.

More discussion here.

But little known is that you can easily and cheaply
build your own smart tv with none of these problems!

Besides starting, stopping, reversing, or fast forwrading
many sources at any time. Accessing them totally
at your convenience.

Just make sure the plain old but fairly new tv has a
HDMI connector, find a cable and connect your
web connected personal computer to it.

An adjustment of the video resoution to 1920 x 1080
may also be needed. As might a VGZ to HDMI adaptor.

Run a preliminary test by using this xylophone duet.

fifty free programming sources. Good early choices
include Fox, CBS, and A&E.

Bizarre. Had a newer scanning fire pager block a nearby
emergency scanner.
Curiously, if not plugged into their
chargers, the two could get within a few inches of each
other with no problems.

But if either or both were brought even near (!) their
chargers, they would interfere up to as much as
eight feet away! The receive-only pager ends up clearly
blocking its active channel on the scanner.

Producing a distinct bleep-bleep-bleep.. that is worse
than unacceptably annoying. Up the wall, even.

Both units were believed properly functioning and likely
both met the normal and usual FCC interference specs.

Adding power line filtering made no apparent difference.

My best guess as to what was coming down is that the
charger power wires were somewhere near a quarter
wavelength and somehow were resonating
. Perhaps
in the same manner as the directors and reflectors in
a Yagi antenna. Thus "focusing" and "amplifying" the
interference directionality.

Or a "ground plane" effect was enhancing the patterns.

Apparently there also are commercial scanner intermod
filter products that deal with this problem.

And a more detailed explanation here of possibly what
is coming down.

The obvious workaround is to keep the scanner and the
pager at least ten feet from each other

This is vaguely reminescent of an ancient and pretty
much long forgotten AM radio sensitivity enhancing
stunt. In which you placed a large tuned loop antenna
a foot or so away from the radio and let resonant
buildup and near field coupling do the rest.

The scheme ended up largely unused and unpopular
in that it was huge and required careful tuning and
repositioning for each station. Strong nearby signals
could also cause problems.

One of the reasons I have always been negative about
Linux and its UNIX heritage is that there are forever
rude surprises piled one on top of another - hardware,
software, rules, culture, and attitude.

Iffen the right one don't get ya, the left one will.

Ferinstance, that amazingly small Raspberry Pi
computer. There is no safe way to set it down unless
you seek out a third party case!
The needed power
supplies are fairly hard to find locally and it is nearly
impossible to determine what their ratings are. Keyboards,
mice, monitors, and cables also need added.

While space is provided for removable flash memory,
nearly two Gigs of bloatware has to be first downloaded
into the chip with a "real" computer before you can even
begin. A minimum of four gigs is recommended.

A dedicated development workspace with a functional
Windows web computer seems to be a must.

Specs for a crucial board chip have Draconian access rules.
Direct VGA monitor support is lacking.

There is not the slightest doubt that the Pi is a major new
development. The question is WHEN in the hassle after
hassle after hassle pileup you switch back to the Basic

Stay tuned for the next level of problems.

For years, I've been fascinated by "secret" rumors of
spectacular wet desert hiking in Arizona's Santa Maria River
area. These days, its a simple matter to do a flyover using
Acme Mapper.

Of its 30 mile or so length, the last and westernmost third
seems pretty much wide, sandy, and dry. This part goes to
Alamo Reservoir from the Las Vegas Highway and routes
throug the Arrasta Mountain Wilderness area. A feeder
area called Peoples Canyon appears to be pristine but
likely quite dry and of restricted access.

Things get much more interesting in the middle third ten
miles between the Bagdad Road and the Las Vegas highway.
The area is often perennial with a few occasional pools.
Some appear eminently swimmable.   The riparian part
tends to get scrubbed out by violent but occasional floods.
This is definitely canyon country with the river cutting
through thousands of feet of  elevation difference.

Winter or spring are probably the best visit times.

But the best part would appear to be the initial ten mile reach
from the Muleshoe Ranch to the Bagdad Road.
The ranch is
where the Santa Maria gets fed from Kirtland Creek and
others. This portion does look like it has bunches of
really spectacular desert pools and quite narrow canyon
vistas. Access would seem to be foot only.

While you are in the neighborhood, there's also opaque
apache tears, a pair of world class bridges, a warm
spring, six mile crossing, one of two remaining company
towns in Arizona, several wilderness areas and the "lost"
Zanarapolis ghost town. Which was really a tungsten mine.

No services, except for the rather unlikely Wayside Inn that
you can't get to from here. More Arizona stuff to do here.

Got my long delayed Raspberry Pi computer yesterday.
This, along with the Arduino seems to be redefining an
hacker electronics re-emergence.

An obvious use for the Pi is for the next generation of
Magic Sinewave research. 8-bit devices required
sneaky tricks to do 12-bit and higher precision delays
that led to code "pinch points" and extra complexity.
Their memory restrictions also made combining
frequency setting and waveform generation in one
deviceboth limited and tricky.

By dropping the Pi down into machine, simple
and brute force obvious{ pattern-value-delay}
can be done for hundreds or more
different amplitudes and hundreds of different

There's also the ability of mixing and matching
magic sinewaves so that the number of pulses
decreases with increasing frequency.
This could
limit the range of the first uncontrolled harmonics
and thus have filtering advantages.

The pi should help in evaluating potential new classes
of three phase magic sinewaves.
There is potential
here for reduced early unwanted harmonics and,  
once again, filter simplification.

Some preliminary third party pi code can be found here.

Yeah, by any metric the Raspberry Pi completely and
utterly blows away the KIM-1. But I strongly like
the KIM-1 better and feel it ultimately will prove to
be far more historically significant.

There's a virtually unknown "CCC Playground" somewhat
north of the Hawk Hollow tank. Here you will find many
dozens and possibly many hundreds of utterly useless
water spreader projects.

This area gives historic meaning to "shovel ready stimulus"
projects, aka "totally worthless boondoggles".

While the area is fascinating to visit, it does take some
remote bushwacking. The Allen Hanging Canal tunnels
under all of this worthless grunge and I have still been
unable to trace its exact path thru this labyrinth.

In places, the water spreaders clearly cross the original
canal route. Strongly suggesting that they are in no
way prehistoric.
They also have a "too new" and "anal"
look about them, besides having jumbled patina.

The exact canal path is somewhat limited as it has to
be of constant slope, below its entry altitude and above
its exit altitude. Besides being likely to stay east of the
wash bottom.

Hawk Hollow tank is a mile or two southwest of Thatcher
International Airport
. Which is rumored to still offer late
night DC3 service to Columbia.

Our foremost example of this had been our water soluble

Other no longer available items included the dimpled chad

civil defense porta-potties, bulk cargo netting for truly bizare
teen clothing

Coronado Vinyards has switched to a wine and tapas lounge
format from their restaurant. So far, the results are superb,
but I am wondering how well the venue will long term fly in
rural Arizona.

I'm not even sure how many of the locals would even know
the difference between "tapas" and "topless". At any rate,
Coronado is located just south of the easternmost Willcox
I-10 exit.

Arizona has a surprisingly wide variety of quality wines

Upload/Download availability will be 24/7.

The probability of paper acceptance will
be 1.0 or 100 percent.

The maximum acceptable publication

Thought we would once again review how to find price
and value of items for possible eBay resale, especially
electronic components. Our usual price point for
"like new" items is typically one sixth of distributor

Obvious starting points are eBay itself and Google.
Less obvious are OEM's Trade and PLC Center.

Plus, of course, the obvious mainstream suppliers
such as McMaster Carr, Allied, Newark, Mouser,
Grainger, and such.

We previously looked at some emerging opportunities in

interesting new summary can be found here.

One of their interesting points is that a one inch diameter
water pipe can transfer as much "cold" as an eighteen

They did not mention magnetic refrigeration through the

little recent progress and outrageous materials costs.

The Bear Springs area is a candidate for a prehistoric
hanging canal
. While I've found nothing obvious so far,
it is unlikely such a major water resource would be
ignored by canal literate people.

There is a huge but abondoned and obviously modern
canal nearby. I had this going FROM Bear Springs
to the north. However, a study by a historian has what
likely is the same canal going TO Bear Springs from
the Lowland Union Canal.

Some of the historian photos do indeed have a prehistoric
look about them.

The only little problem I have with the reverse canal
is that Bear Springs seems to be around 150 feet or so
HIGHER than the Union Canal.

The mystery deepens, but the known prehistoric
canals take precedence in resolving known issues.

A fundamental rule of engineering design: Any
uncontrolled parameter will likely go against you

Two wildly different examples...

On our magic sinewaves, the tradeoff for zeroing
out any number of low harmonics requires that the
first few uncrontrolled harmonics will inevitably
be fairly large and require careful filtering.

On our prehistoric hanging canals, in exchange for
extreme energy efficiency in construction, the canals
will of necessity end up longer that would be optimal
using modern construction techniques.

Thus, longer "S' or "U" constructs are needed to
avoid energy wasteful cuts or fills
. In other places
miles of parallel canal may be needed to gain a very
few feet of required elevation difference. The split
between the Mud Springs and Jernigan canals is
a typical example.

Excessive length gives us yet another potential proof
of prehistoric age .

One of our lecture attendees felt I was too harsh
on the compressed air car scam. Once again, there
are fundamental physical laws that absolutely
guarantee that compressed air cars flat out ain't
gonna happen

The energy density of compressed air at best is
around 15 watthours per liter. Compare this against
lead acid at 30 wh/L or gasoline at 9600 wh/L.

Efficient air compression demands it not get warm
when squashed.
At the very least, this takes multiple
stages and elaborate intercoolers. No means of
true isothermal air compression is known.

Compressed air motors are outrageously inefficient.
An efficient air motor would have to noiselessly exhaust
at zero velocity and at ambient temperature. And do so
over an extreme pressure range.
With no ice issues.

The fire service has spent over a century trying to
use compressed air to perform useful work for
such things as vent fans, fast cutters, spreaders, and
such and has spectacularly failed.
Again, due to
fundamental physical laws that trash efficiency.

Yes, compressed air is shop floor useful because
its convenience overwhelms its pitiful efficiency.
And huge public utility underground compressed air
storage might prove viable because it lacks the severe
vehicular restrictions.

Believe it or not, there really is a Nothing, Arizona and a
Nowhere, Arizona. They are/were roughly 60 miles apart.

Things get somewhat confusing when Nothing sometimes

At any rate, the two would make a very interesting winter or

Found what may be a bizarre feature of GhostScript that may
cause some problems with at least some of my PostScript
programs. Particularly existing ones.

A lot of these programs use the log file as their primary
output. Normal GhostScript operation places a scrolling
limit of 82 lines or so in their reported log file results.

There is no such limit in Acrobat. But, as we have
recently seen, Adobe appears to be flushing any
Distiller use that writes disk files.

Here is a typical demo...

0 1 1000 {= =} for

An obvious GhostScript workaround is to output via custom
and specific files
, rather than the quick-and-dirty use of the
stock log file.

A second workaround is to run GhostScript from the
command line
. Right clicking on the command screen
can pull up properties that let you change the amount of
scrolling lines permitted.

I have long recommeded using the Distiller in Adobe
Acrobat as a general purpose PostScript computer.
has been the primary method for running and using my
many hundreds of PostScript applications.

Starting with Acrobat 8, Adobe made using the file
command in Distiller difficult. They recently appear
to be in the process of completely eliminating any
file capability
. Any and all references on their
website to Acrodist-F and similar options have
apparently been meticulously flushed.

And I have been unable to get Acrodist-F to
work on Windows 8.

The good thing about the file command is that
it let you use PostScript to read or write virtually
any file in any language
. This was particularly
useful for manipulating bitmaps or generating
fancy JavaScript programs. But, as our website
shows, has countless other uses.

The bad thing about the file command is that its
abuse potential is off the wall
, since it can easily
plow an entire computer or network.

Fortunately, free GhostScript retains the ability to
deal with unfettered file commands. It also can
be used to run most of my programs and most of my
applications directly or with minor modifications.

The only minor problem I have found so far using
GhostScript is that max may be a reserved word.
In my Architect's Perspective distortion correction
utility, A change of the max variable to max1
appears to be a working solution.

The customer demand for online auctions may be
lagging waay behind the number of them being offered
by the traditional auction houses.
There seems to
be a unique but temporary opportunity here with
many auctions apparently now having as much as
one quarter (!) of their items unsold.

Yeah, unsold stuff traditionally was scrap, junk, or
had massive rigging issues. But this seems different
in that there would appear to be a major unbalance
between offers and demand.

So, on any auction of interest, it now would seem to
certainly pay attention to what got unsold

rethink your interest in it, make unsolicited lowball

I'll be presenting a revised and updated talk on our prehsitoric
hanging canals Saturday December 1st at 6:30PM in the Jupiter
Room of Discovery Park.

Here is an excerpt of what may end up the Courier PR...

"Prehistoric hanging canals of the Safford Basin"
subject of Saturday's free Discovery Park Lecture

Local author and researcher Don Lancaster returns
to Discovery Park this Saturday December 1st at
6:30 PM. As part of Discovery Park's ongoing fall
lecture series.

The presentation will report on the latest updates
and rediscoveries on a stunning world class
series of Safford area mountain stream fed prehistoric
canals that are literally "hung" high on the edges of
steep sided mesas.

Over twenty hanging canals remain virtually unknown
with a total distance of at least forty miles.
The canals are believed to date from the 1350's.
Some have also seen historic adaptation and a few

still remain in active use.

The construction of a hanging canal can be
exceptionally energy efficient in that its slope
can be made largely independent of terrain. The high
side of the canal is often "free" and construction
can largely take place across rather than along the

In many places, the canals provide a strong illusion
of "water flowing uphill". In reality, most of their
slopes are at a nearly optimum downhill grade. The
evidence suggests that virtually every drop of
northeastern Mount Graham stream water was put to

While no survey tools are known to survive, "pilot
extensions" of the canals themselves were thought
to serve as water levels to establish the needed
grades. Many independent arguments verify the
prehistoric origins of these canals.

These include roads, tanks, fences, dams, and even
cemeteries that run roughshod over the canals
without access or accommodation; large Mesquite
trees and barrel cacti mid channel; uniform desert
varnish, caliche, and lichens; absence of any
apparent modern tool use; and, above all, a
purposefulness that clearly and uniquely meets
prehistoric needs. The newly updated presentation
can be previewed at Don's

There is no charge and families are welcome.

some of the items are buried in non-obvious places.

But what is not at all obvious if you are, say, after
a +3 and -3 volt supply, is that the cell stacking is
highly unusual!

The cell sequence is 1-4-3-2!
The "center tap" is
thus at "three quarters".

I've been refurbing a bunch of Variacs for our eBay

ailments: The neon pilot lights are burned out and/or
the power switches fail to work.

Both of which are inexplicable in that neon pilot
lights should be virtually indestructable and the switches
seem to have some burned black grunge in them.
Like their contact grease was set on fire.

Perhaps there is some transient phenomonen when
Variac power is applied in the wrong part of the ac

Canal 21 aka the Blue Ponds hanging canal may end
up being wishful thinking.

A field verification visit to this location has revealed
what looks a lot more like an early wagon road,
complete with broken horseshoes and an often
double spoil row.

And the obvious short canal at this location seems
to be modern, judging from its concrete diversion
section. And appears to be a simple switch to select
the upper or lower Blue Pond as a destination.

A presumed hanging portion remains unchecked
here, but it now would likely seem to be a wagon
road continuance. Closer aerial photo inspection
again suggests double spoil rows in places.
Although it is not quite clear why a wagon road
would get hung on a mesa edge.

There are some sparce tradeware shards remaining
in the area. And the location is certainly reasonable
for a major early hanging canal.

Canal 21 cannot quite be written off, but its
evidence to date seems to be diminishing.

The immediate questions are which of these allow convergent
full amplitude solutions and what reductions, if any, can be
provided in close in filtered unwanted harmonics.

There would seem to initially be 4 + 16 + 64 = 84 possible three
tier solusions covering n=2 to n=12. And 340 possible four tier
solutions covering n=2 to n=16. But there would seem to be
no point in exhaustively evaluating these if their one or two
tier predecessors were previously found to be nonconvergent,
limited amplitude range, or disallowed..

In general, the "less uniform" the "carrier" is, an assumption
can be made that the spectral energy will be shifted higher.

How far this can go and how much improvement can be
made has yet to be determined.

I can't seem to be able to get Acrodist-F to work
in windows 8!

Yes, you can get the command line in Windows 8
back by seaching on aps that start with "c" and
creating a C:\Windows\SysWOW64\cmd.exe shortcut.

The PostScript language has long been exceptional
in that it can read or write most any disk format in
most any language!
I've personally based many
thousands of PostScript programs on this ability.

The easiest and simplest and most mainstream way
of deaaling with this was to use Acrobat's Distiller
as a general purpose PostScript computer.

However, way on back in Acrobat 8, Adobe decided
that the abuse potential of this incredibly powerful
write-or-delete--any-system-file ability had some
utterly awesome evil possibilities.

So they placed what then seemed like a reasonable
restraint on disk access by requiring you enter Distiller
via a command line Acrodist-F any time you genuinely
needed full disk access.

I get the feeling that they want to completely eliminate
any possible Distiller use for better and more important
PostScript applications. Partial proof of this is that Adobe
has kept Acrodist-F a secret
and seems to have dropped
any mention of it on their website for several years now.

The obvious workaround is to use public domain GhostScript
to run unfettered PostScript programs.

Preliminary testing shows that must of my aps will work
just fine under GhostScript.

The energy density of gasoline is 9600 watthours per
Considering heat engine efficiency limits, any
battery that was to one on one compete with gasoline
would have to have around a 4500 watthours per liter
energy density.

Lithium Ion batteries have a theoretical imit of about
1500 watthous per liter, but off-the-shelf units are
lucky to hit 250 watthours per liter.

But a new and close-in development uses a crushed
silicon anode that approaches 1000 watthours per
liter. Per this anouncement and this analysis.

Better yet, there is a potential lithium air battery
technology that has the ability to theoretically exceed

           November BLM Brown Bag Talk
“Prehistoric Hanging Canals of the Safford Basin”

Safford, Ariz.  As part of Bureau of Land Management
(BLM) Safford Field Office’s ongoing Brown Bag lecture
series, Thatcher author and researcher Don Lancaster
returns on Thursday, November 1, at noon.  His
presentation will report on the latest updates and
rediscoveries on a stunning world-class series of Safford
area mountain stream fed prehistoric canals that are
literally “hung” high on the edges of steep sided mesas.

There is no charge and families are welcome so bring
your own “Brown Bag” and spend your lunch hour learning
about these unique local features.  The BLM is located at
the corner of 14th Avenue and 8th Street in Safford.

Over 21 hanging canals remain virtually unknown with a
total distance of at least 40 miles.  The canals are believed
to date from the 1350s.  Some have also seen historic
adaptation and a few still remain in active use.

The construction of a hanging canal can be exceptionally
energy efficient in that its slope can be made largely independent
of terrain.  The high side of the canal is often “free” and
construction can largely take place across rather than along the

“In many places, the canals provide a strong illusion of “water
flowing uphill,” said Lancaster.   “In reality, most of their slopes
are at a nearly optimum downhill grade.”

The evidence suggests that virtually every drop of northeastern
Mount Graham stream water was put to use.  While no survey
tools are known to survive, “pilot extensions” of the canals
themselves were thought to serve as water levels to establish the
needed grades.

Many independent arguments verify the prehistoric origins of
these canals.  These include roads, tanks, fences, dams, and
even cemeteries that run roughshod over the canals without
access or accommodation; large mesquite trees and barrel cacti
mid-channel; uniform desert varnish, caliche, and lichens;
absence of any apparent modern tool use; and, above all, a
purposefulness that clearly and uniquely meets prehistoric needs.

I was appalled that somebody on a newsgroup had to ask
what the computational heritage of PostScript was.

PostScript was related to and derived from Forth. In a
third cousin, twice removed sort of way.

Forth in turn was largely invented as a control language for
astronomers. Its hallmarks were being strongly stack oriented
and using a Reverse Polish notation. When a command is placed
on top of the stack, underlying stack entries contain all the info
that is needed to carry out that command.

I still do not have positive proof over whether "Canal 21"
is real or not. Because of rough 4WD tracks and difficult
hiking routes.

But I did manage to get within 300 feet of what sure
appears to be a typical mesa hanging portion.

I did also verify that the more western traces a few
hundred feet to the west are almost certainly a city
of Safford water line.
One of the hints is that there
are very few prehistoric canals that include chlorinator
buildings. Handmade "old style" rivited steel scrap
pipe gives additional age and use clues.

If real, #21 would be one of the more significant canals.

It would appear to originate in Frye Creek and seems
to be headed to yet unverified fields under the Blue

Those old "oval" three pin round HP power supply cords
have pretty much gotten impossible to find at sane prices.

More often than not, there is not enough room behind the connector
to allow some more modern chassis mounted solution. Not to
mention some awkward nibbling or filing,

One workaround is to take an IEC C-14 male three pin power line
, shorten it to a few inches and solder it directly to the HP
pins. The live connections can then be shrinkwrap protected or
glopped with silicon rubber.

The middle pin is always green and safety ground. There are two
different conventions, depending on manufacturer for the outside
pins. If possible, route white to white and black to black.

But it usually does not matter much, unless there is some hot

One of the more interesting things to do with Google Earth
and the .kml custom programming language might be to
slice up an area to only show imagery between two different

Our canal research still has many unknown gaps. Usually
Ockham's Razor lets you conclude that the canal going into the
gap is the same one as the one coming out. It is also a
given that the reach in the gap can be no higher than the
input elevation and no lower than the output one.

A further reasonable assumption is that the slope in the
gap is more or less constant, and will likely be near half the
height at half the distance.

The lower slice could be opaque black, while the upper
one might be a highly transparent white.

Other potentially more nerfarious uses of altitude slicing
could be to pin down the location of a site for which you
only know the altitude and general neighborhood. The
strength and direction of the altitude gradient could
also sometimes be of help in further narrowing things down.

is the correct spelling and we do not know William's

A possible twenty first (!) hanging canal canidate has been

This has not yet been field verified, but the topography
and imagery both seem
quite favorable. It would seem
to source in Frye Canyon and deliver somewhat west
of the Longview area.

Total projected length might approach four miles.

A hanging portion is likely at the second and third
southernmost markers.

The somewhat more obvious reach roughly 500 feet
to the west is believed to be a buried City of Safford pipeline.
Presently in disuse because of a chrolinator issue.

While there are many examples of "steal the
plans" and "dig
out an old ditch" in the area, there is no compelling evidence

Some Raspberry Pi sourcecode for Magic Sinewave
generation can be found here.

The code is potentially much simpler and easier to write
than PIC code because of the availability of high resolution
and low jitter single step delays.

The enormous memory space also makes internal generation of
both frequency and amplitude quite feasible.

Brute force machine language remains required. Service routines
in Linux introduce unacceptable jitter that adversely affect
supposedly rejected harmonics .

It still might be desirable to shorten the actual code generation first
by using quadrant symmetry and second by going to some sort of
indexed or table lookup for the delay values.

But, even at 1K words per magic sinewave, only 100K is needed
for one amplitude, and 10 Megs for a hundred frequencies. Thus,
entire families of magic sinewaves should easily fit one SD boot card.

As is often the case these days, brute force can thus triumph over

A magic sinewave high speed calculator can be found here.

Google Chrome seems to have an infuriating property that
can cause you all sorts of grief: It does not check too thorourghly
before deciding to reuse a cached copy of a requested filename.

Ferinstance, say you are doing some site maintenance and upload
a .pdf file that is bad or needs modified for one reason or another.

You find the problem and fix it, retaining the same filename. Chrome may
refuse to give you the new file, using the one in its cache instead!

The workarounds are to switch to a different browser anytime you
suspect this is happening to you.

Waiting a day also seems to usually clear the problem.
Rebooting may also help. As may temporary filename chnges.

Common mode chokes are a somewhat unusual and sometimes
pricey component used to reject ingoing or outgoing ac line borne

They are basically a two winding toroidal coil. One winding goes in
series with each ac input power wire
. Together the bucking action of
the two working together provide a high impedance in the low
Megahertz range where much of RFI and interference is centered.

A physical safety barrier is also usually provided. This is usually
a "spanning" insulator. Common mode windings are often
paralleled bifiliar or tetrafilar to improve their high frequency
rejection and maximum current capability.

There's a lot of hidden or little known features of Google Earth.

Ferinstance, you can use the history bar to find out when the
last resolution upgrade was made

notification of your favorite area updates by using this link.

There's also a time of day slider that can be used to vary
the contrast in any particular area. I've found this very
useful to reveal hidden mesa edge details in our canal studies.
The image tone is also somewhat adjustable.

Also available is a ruler that can measure exact distances in
your choice of units.

The altitude reading changes as you mouse around, and does
so apparently to much better than GPS resolution. One of
the characteristics of a canal is that it has to go downhill at
a constant and measurable slope
. Repeated checks can
separate a potential canal from a cowpath or 4WD track.

Acme Mapper also uses the Google Earth and Google Map

The water powered car overunity fiasco continues unabated
on the web. Driven primarily by one or more individuals in terminal
denial over
how bad they were ripped off in a "gross and
egregious" fraud scam.

Believe it or not, overunity electrolysis is in fact possible up to
one-sixth overunity.
This is caused by the process being up to
one sixth endothermic at very low gas production rates. But
cell losses utterly and totally overwhelm for reasonable or
amortizable production rates.

The cause of further overunity claims rests on largely incompetent
measurements, outright scams, delusion, or not having the faintest
clue over what legitimate science and genuine research is.

There is a thermodynamic concept called exergy that tells us that
a kilowatt hour of grid, pv, or alternator electricity is worth ridiculously
more than a kilowatt hour of unstored hydrogen gas. Caused by the
reversibly recoverable energy fraction being much less.

Which tells us that electrolysis from high value sources simply
ain't gonna happen
because the process is identical to 1:1 exchanging
US dollars for Mexican pesos.

The economic loss in electrolysis at best would be 3:1 since no
way is known to convert hydrogen back to electricity at greater
than 33 percent efficiency

Otherwise known as an electrocity.

Which tells us that the first 300 percent discovery in overunity
electrolysis would not be of ANY interest in the least, because it
STILL would be destroying value.

The kicker, of course, is this: Any higher percentage overunity results
would have long ago been totally and painfully obvious.
Even without
their necessary side effects of black holes and any similar explosions
that might only take out a city block or two .

car can be found here and here. More on "real science" energy here.

For a number of reasons, it pays to work backwards on any
online auction.
For your best buys and best winning odds
strongly favor the high lot numbers.

Firstoff, the auction house tends to use the lowest lot numbers
for the really pricey stuff that you are unlikely to be interested in.

Secondly, there are far more early bids on the first page of
an online auction than there will be on higher pages. And the
fewest early bids ( if any ) will show up on the last auction page.

Early bids, of course, are utterly pointless and monumentally stupid.
Your best online auction strategy is always to proxy bid your max
ONCE just BEFORE the time that trips any automatic extensions.

Thirdly, your competitors are likely to have their needs fulfilled,
become bored, or run out of money late in the auction. Especially

The super secret insider directory of Arizona indian ruins has
long been maintained by ASM, aka the Arizona State Museum.

The basis is a gridded system, such as CC-1-37 in which the CC

Access to the data base has been tightly restricted and often outrageously

Solar pv panel prices are clearly in free fall. Although still nowhere
remotely near being a renewable or sustainable resource capable
of net energy production.

Sites such as this one or this one are offering panels in the
fifty to eighty cents per peak panel watt range. And some
China sources are talking thirty cents per peak watt.

New schemes are dramatically reducing the amount of
material needed and the costs of those materials. And
learning curves and economics of scale are rapidly
setting in.

Subsidies with their obscene price supports and "iceberg"
hidden costs thankfully have nearly vanished

But, curiously, the closer pv panels get to net energy production,
the MORE they will temporarily continue
to be a gasoline destroying
net energy sink.
Why? Because of the zillions of new investment
dollars thrown at emerging opportunities.

More on the equivalence between dimes and kilowatt hours here.

Net energy breakeven ( along with renewability and sustainability )
can be anticipated eight to ten years AFTER the average panel price

As usual, the ongoing source for the absolute worst in the
way of perpetual motion machines is Keelynet.

Which, of course, leads to unintended but utterly fascinating reading.

As with ALL of the others, the latest stupidity is not even wrong
in several fundamentally different ways.

It consists of an inverted cap falling in water. Potential energy is
somehow converted to electricity as the cap falls.

Problem number zero is that the system is obviously thermodynamically
as unwanted waste heat will inevitably be generated due
to the water viscosity

Problem number one is ( just like no windmill can exceed 59 percent
) is that the cap would have to fall at zero velocity for
an efficient recovery.

At the bottom of the cycle, a bubble of air is introduced into the cap.
Allowing the cap to float back to the surface for the next cycle.

Problem number two is that water exerts a pressure of roughly half
a psi per vertical foot. Thus, the injected air has to have work done
on it to allow its introduction.

Problem number three is that no method is known to efficiently compress air.
For efficient compressibility demands an isothermal process.

My own very first perpetual motion machine, of course, bypassed all these
problems. See column #33.

The "Tesla Turbine" nonsense is infesting the newsgroups again.

One more time: Bladeless turbines and pumps DEMAND a
thermodynamic irreversibility for their FUNDAMENTAL operation
of maintaining a lossy shear force in a viscous medium. And are
thus useless when high efficiency is a factor.

They, of course, do not work at all if the fluid has zero viscosity.
I'd expect them to be far less efficient in vapor rather than liquid.

These devices ~are~ superb as shit pumps or when pumping frozen
chickens or live fish. As the now defunct leading supplier
tells us, blades have to be added if higher efficiency is needed.

Yes, it may make sense to use pv panels on featherweight
student racers
to teach engineering constraints and tradeoffs
involved in system design .

But pv panels on a full size vehicle are ludicrously absurd.
Far beyond the "What are they on and where can we get
some of it?
" level.

Incoming solar radiation on a clear Arizona summer day might
approach 1000 watts per square meter. Present pv efficiencies
beyond the inverter or sweet spot optimizer rarely exceed
ten percent. For 100 watts per square meter.

But a car panel will almost always be pointing in the wrong
in shade, under clouds, or inside a carport or a
garage. Which means the effective panel output will be
very lucky to approach thirty watts total for only a very
few minutes on a very good day.

Which would almost ( but not quite ) be enough energy for
the power mirrors.
Provided you did not adjust them very
often. And that is before you factor in the energy needed
to pay for the panel, the cv aerodynamic degradation of
the vehicle, the panel heating, and the excess cooling needs
from being in the sun all the time.

And ignores the fact that not one net watthour of pv energy
has yet been produced.
Despite dramatically recent improved
pricing and performance, all of pv today remains a gasoline
destroying net energy sink. Net energy breakeven can be
anticipated eight years after the panel pricing drops
under twety five cents per peak watt.

It might be interesting to ask what can be done with a 55
foot eighteen wheeler trailer totally covered with panels.
At best you would have about fifty square meters of misaligned
panel surfaces. At ten percent efficiency, peak power
might be about 5 kilowatts. Or something like seven

aka... not worth pissing over. And certainly unamortizable.

The AMOE gets at least a dozen requests a week as where to find
instant wholesale drop shipping suppliers. Since eBay prices are almost
always well BELOW wholesale, the only recommended company here
would be Norfolk & Waay.

Who this week only have free sample pallets with free shipping from
their choice of Sears, Neiman Marcus, Land's End, Sharper Image,
Macy's, or Bruno's Trucking.

The REAL key eBay source secret is simply this: Quality merchandise
MUST have taken a stupendous hit in value BEFORE it will be of
interest to a successful eBay seller. Sources that work for me include
mil surplus, community college auctions, industrial bankruptcies, and
dot com failures. Some recent medical stuff has also worked out well.

Other key eBay success secrets include always seeking out a 30:1 or
higher buy sell ratio, seeking out sales above $19.63, listing not less than
75 items at any time, spending at least two hours post processing each
photo, and selling US only and Paypal only.

How can you deal with shipping or receiving the wrong
eBay item?

Any individual who receives something in the mail that they
did not order is under no obligation whatsoever to do
The item can be treated as a gift or thrown away.

Issue a full refund or fully comp the item if you are an eBay

Under no circumstances should you ask the wrong
recipient to forward the item. Even getting it returned
is risky.

Did I ever tell you about the day I invented the frisbee?

It was at a Sunday School picnic at Rose Barn in North Park.
Sometime around 1953. Seems they had a kiddy contest that
involved sailing paper plates for a ball mitt.

The first six kids sailed their plates right side up and they
all went about seven feet plus or minus an inch or two.

I was last in line and decided to sail my plate upside down.
It almost went thirty five feet. Until the last instant when
a puff of wind caught it and blew it out of sight downhill.

Two fundamentally different methods have been used
earlier to solve the magic sinewave  equations.

The basic problem is to solve math equations similar to...

cos ( 1*p1s ) -cos( 1*p1e )+…+cos( 1*p7s ) -cos( 1*p7e ) = ampl* pi/4
cos ( 3*p1s ) -cos( 3*p1e )+…+cos( 3*p7s ) -cos( 3*p7e ) = 0
cos ( 5*p1s ) -cos( 5*p1e )+…+cos( 5*p7s ) -cos( 5*p7e ) = 0
cos ( 7*p1s ) -cos( 7*p1e )+…+cos( 7*p7s ) -cos( 7*p7e ) = 0
cos ( 9*p1s ) -cos( 9*p1e )+…+cos( 9*p7s ) -cos( 9*p7e ) = 0
cos (11*p1s)-cos(11*p1e)+…+cos(11*p7s)- cos(11*p7e ) = 0
cos (13*p1s)-cos(13*p1e)+…+cos(13*p7s)- cos(13*p7e ) = 0
cos (15*p1s)-cos(15*p1e)+…+cos(15*p7s)- cos(15*p7e ) = 0
cos (17*p1s)-cos(17*p1e)+…+cos(17*p7s)- cos(17*p7e ) = 0
cos (19*p1s)-cos(19*p1e)+…+cos(19*p7s)- cos(19*p7e ) = 0
cos (21*p1s)-cos(21*p1e)+…+cos(21*p7s)- cos(21*p7e ) = 0
cos (23*p1s)-cos(23*p1e)+…+cos(23*p7s)- cos(23*p7e ) = 0
cos (25*p1s)-cos(25*p1e)+…+cos(25*p7s)- cos(25*p7e ) = 0
cos (27*p1s)-cos(27*p1e)+…+cos(27*p7s)- cos(27*p7e ) = 0

There is a fundamental proof that polynominal equations
above order five cannot directly be solved
. On the other hand,
a carrier can be distortionlessly modulated and demodulated,
so viable solutions should exist.

One approach is called Newton's Method in which you make
a guess, improve that guess using the function slope, and
keep iteratively repeating the process till acceptable accuracy
results. Variants on Newton's method might involve Taylor
, Chebycheff Polynomonials, or trig identities.

My earliest and simplistic approach can be called "Shake the Box".
While excruciatingly slow, it was responsible for first proving the
viability of the magic sinewave concept and finding real results.
Examples of the method can be found in the Magic Sinewave
Historical Archive

With "Shake the Box", you first make a 0.1 degree change in the
first edge of your first pulse
. You keep making changes till
the distortion no longer improves. Then you repeat with an
0.01 degree change, then 0.001, etc... You then go to the second
edge of the first pulse and then repeat this for all pulses.
After several long trips an acceptable solution should result.

In hindsight, we are really just solving a partial differential
equation set. It might be interesting to use fancier math to
clean up and speed up this primitive approach.

The "standard" method used in the present calculator and
its still buggy improved version makes use of this trig

cos(a+x) = cos(a)cos(x) - sin(a)sin(x)

If x is very small, this enormously simplifies to...

cos(a+x) is approximately cos(a) - x*sin(a)

Since cos(a) and sin(a) are plain old numbers from
our previous guess, the trig vanishes! Poof. Gone.

You can substitute cos(a+x) in the above equations
and then rearange the terms so the variables are
on the left and the constants on the right
. Which
leaves you with a plain old nxn linear equation set.
One that is easily solved by Gauss Jordan Reduction,
provided you watch for problems on higher n.

As the present calculators show us, the results are
amazingly and increrdibly fast, approaching real time.

I've recently been made aware of an alternate solution
method that uses even fancier math to improve the
stability and solvability of higher n values. I still do
not fully understand the method, nor appreaciate its
claimed benefits.

A complementary pulse series is used that with the
intended pulse solutions sums to a square wave.
Coefficients on the sought zero harmonics become
1/3, 1/5, 1/7, 1/9 ... on the complementary series.
Each pulse is placed in a vector space that involves
a cycloid. Solutions are apparently iteratively
based on differentials only.

Incredibly, solar energy bankruptcies seem to be approaching

clearly betting on the wrong horses, the silicon shortage now

Yet, the best present panel pricing at best remains about TWELVE

We've seen here and here that many Magic Sinewave solutions
can be based on making a guess, and then improving that
guess by solving a square nxn linear equation using Gauss
Jordan reduction
and some extra care.

Once again, Regular Magic sinewaves are somewhat inefficient in
that they zero out two fewer low harmonics than the Bridged Best
ones. But they retain a curious property in that their
first uncontrolled harmonics can be precisely opposite in sign
to BBE
. Sadly, to date, any cancellation attempts have met with
failure. Largely owing to loss of quarter wave symmetry.

But the Regular magic sinewaves had a problem in that you seemingly
had only n-1 equations in n unknowns. A previous workaround
held one variable at its "best guess". This did work, but may have
produced "not quite right" results. It did, however, offer a modest
range of tuneability.
Whose implications have yet to be explored.

Here's an alternate workaround yet to be checked out: Write a new
zero equation halfway between the first and second groups of
larger uncontolled harmonics.
Ferinstance, on a n=8 regular magic
sinewve, the first uncontrolled harmonics center on h31 and the
second larger ones on h61. Write a new equation zeroing out h45
or h47.

If air powered cars are so utterly and laughingly ludicrous, why
are power utilities considering to use air powered peaking

The energy density of compressed air does not quite approach
that of lead acid.
15 watthours per liter is very hard to acheive.
And recovering even a fraction of that can
be exceptionally tricky.

Further, air tends to heat when it is compressed and cools when
it expands
. Both of these severely rob the efficiency.
air motors work best at LOW pressure differentials that do not
change much
Normal industrial air motors are highly inefficent.

The utilities beat these limits by using huge insulated storage
tanks in the form of underground caverns. The heat of compression
can be stored along with the air itself.
Only a tiny fraction of the
stored air needs used on any cycle, making for much higher
recovery efficiencies. And the pressure differentials can be
quite low, further aiding efficencies.

A compressed air car might approach this by using a 20,000
cubic foot highly insulated storage tank. Low cost and low drag,
of course.

Even then, the best real world efficiencies of compressed
air peaking storage today is only slightly over fifty percent.

But the large cost differential between baseline power and
peaking power can make air storage projects both
compteitive and cost effective. Especially if building a
new power plant can be avoided.

The |jDeadman |jCanal
The Deadman canal is presumed to be a 6.4 kilometer long partial historic rebuild
and reuse of a prehistoric original. The route is well marked on the topo maps
and is believed to originate in Deadman Creek near its perannual flow limit.

The reach of the canal between < N 32 44.354' W 109 48.687' > and
< N 32 44.697' W 109 48.394' > appears to be consistent with other significant
hanging portions of nearby canals. This reach has apparently been completely
buried by a City of Safford water project pipeline. There is no present use of
this resource owing to a chloninator issue.
There is a small collection pond at < N 32 44.697' W 109 48.394' > that marks
the diversion limit of extensive modern rework. The canal continues eastward
along the HIGHEST portions of Deadman Mesa still in its apparent original
prehistoric form. This portion of the canal flows year round to this day. Some
diversions into modern cattle tanks seem to have been done. Some of these
appear to be in current disuse. No apparent use of modern tools and
techniques appear below the collection pond.
At < N 32 45.640' W 109 46.877'>, the mesa top is literally two meters wide,
with a one meter canal centered on it. It is unlikely there is any similar routing
anywhere in the entire southwest. Attribuiting this to coincidence would seem
highly improbable. At this point, diversion of the canal into three different
routes would appear easily done. Thus forming a "three way switch". One
route would lead to Porter Springs tank and a well established Longview
prehistoric habitation area. However, only very limited hints of canal
structures have been found in this area, which is characterized by numerous
apron enhanced check dams. The center diversion currently routes to an
apparently abandoned Lower Deadman Tank. Fields or prehistoric
evidence in this area have yet to be extensively studied. The eastern
diversion presently seems to route to Upper Deadman Tank and would
appear to be consistent with linking to the Twin West canal.
An alternate source deemed less likely for Twin West could be found
at < N 32 44.098' W 109 45.737' > As considearably time, energy, and
engineering obviously went into the Deadman Canal, use questions arise
if Twin West is not a credible primary destination.
Some enignmatic constructs near < N 32 45.564' W 109 45.864' > and

An improved version of our standard Magic Sinewave
can be found here. It still has some fairly minor
issues, so I'm still not officially releasing it just yet.

Properly working are new harmonic calculations out to the
177th. Solutions for Best Efficiency, Bridged Best Efficiency,
and Delta Friendly are now available up to n=23.

The internal calculations are only partially extendable without
code revision.

n=8 examples have been added for Regular and Nonzero Bridged
magic sinewaves. But have yet to be expanded to other n values.
These are less efficient but have the curious property that their
early unwanted harmonics are opposite in sign to BE and BBE

Attempts to exploit this feature have failed to date, largely
to a lack of quarter wave symmetry.

The new calculator includes a new and vastly improved way
of calculating real world quantization. Its only tiny drawback
is that it is not yet working properly.
I suspect this is due to
a minor math error. The ability to export quantized values
has also been newly added.

I'd also like to add spectral plots, both a linear and a log one.
For which I am still exploring JavaScript bar code solutions.
I think I just found a good "steal the plans" source.

"Pretty Printing" techniques have largely fallen by the

multiple columns, you want them to stay aligned, even
if the number of digits in a count are different or if
the math rounds off trailing zeros.

Here's some stunts that were used in yeasterday's
roll distance measurement scheme:

First, the process is infinitely simpler if you use
a fixed pitch font such as Courier.

Leading edge adjustment of simple counts can
be crudely done some something like this...

dup 10     lt {( ) print} if
dup 100   lt {( ) print} if
dup 1000 lt {( ) print} if

Many newcomers to the PostScript language will get
maddeningly infuriated when the contents of their
strings suddenly and mysteriously change well into
a program's execution.

The cause and cure is often simple: PostScript
normally does NOT duplicate a string each time
it is newly referenced
. Instead, it only provides
a pointer to the original string.

This makes for much lower memory use and
greatly simplifies garbage collection.

The solution is to provide your own new

assemblage or a non-obvious alternate apparently has to provide Robinson Canal and
possibly Riggs Complex water. Not yet field verified.

Frye |jMesa |jConstructs
A recent revision of Acme Mapper < > has revealed
some unique potential artifacts along the northern and upper elevations of Frye
Mesa. There is a possibility of a hanging canal system that sources the Robinson
Canal as well as some potential field regions both up and down canyon. If these
as yet largely unstudied discoveries are in fact prehistoric, the engineering
implications could well be stunning. Besides beng the "crown jewels" of the
entire regional hanging canal systems.
The fact that most of Frye mesa is lower in elevation than the constructs would
tend to exclude watershed gathering possibilities. Shuttling water "sideways"
from Spring Canyon would also appear rather unlikely. Strongly suggesting
Frye Creek itself as the Robinson Canal source. The highest feasible water
takein point would likely be at the base of Frye Mesa falls at < N 32 44.768'
W 109 50.282' >.  It is not yet clear whether any viable hanging canal route
exists, nor whether it was in fact prehistorically exploited. But there are
definite linear satellite imagery features at < N 32 45.017' W 109 50.271' >,
<  N 32 45.125' W 109 50.236' >, and < N 32 45.196' W 109 50.257'>
that suggest potential canal reaches.
A unique series of braided and presumably manmade water channels of yet
to be determined age appears to begin near the Frye Reservoir turnoff at
< N 32 45.316' W 109 50.104' > and routes to a potential gathering and
dispersal pond at < N 32 45.605' W 109 48.686' >. While intermediate
areas clearly show definite signs of CCC water spreader involvement,
these structures would appear to be later add-ons of opportunity running
across rather than along the braided channels.
The ponding area appears to split into two separate potentially prehistoric
canals. The western one at < N 32 45.535' W 109 48.820' > seems highly
unusual as it would appear to deliver water UPCANYON. This canal ends
in a deep and presumably manmade channel at <  N 32 45.467' W 109 48.908' > .
A study of the USGS topo map would reveal that Frey Canyon widens
considerably at this point while assuming a much more modest elevation slope.
Leading to the possibility of prehistoric fields in this area that could be the
reason for the unusual water delivery system direction.
A second eastern apparent delivery canal at <  N 32 45.587' W 109 48.473' >
seems to route water downcanyon in a reasonably expected manner.
And could be the water source for the Robinson Canal whose study area
extended from <   N 32 46.004' W 109 47.919 > northeastward.
An alternate water source could be in the area of Frye Mesa Reservoir.
The topography in this area was seriously compromised both during initial
construction and later rebuilding and revision. This alternate does seem
somewhat more topographically favorable, but would exclude some of the
earlier potential channels and braided delivery routes.

The |jJernigan |jCanal
The Jernigan canal is a western branch of the Mud Springs Canal. It
likely is 2 kilometers or 1.2 miles long  It terminates in a French Drain
cascade and routes to an apparent prehistoric field area in the vicinity of
the old Central dump and near sites previously studied as EAC field
projects   << Jim -- Need Site Numbers and Jernigan Reference?  >> .
The Jernigan Canal is characterized by sweeping "double S" curves
apparently used to maintain slope independent of terrain and is
moderately hanging near its northern terminus. A fairly deep ( 90 CM )
and fairly long ( 100 M ) cut is present near its northern extreme loop.
One seven inch Mesquite tree is present mid channel suggesting antiquity.
At one point, thet canal mid route returns remarkably close to the Mud
Springs canal, with a kilometer or more of converging dual channels
apparently purposely used to gain only a very modest elevation difference.
Two large gaps remain in the canal's exploration, possibly explained by
sheet flooding or unverified alternate routes. An associated "solid
aquaduct" like structure has yet to be age determined and remains
highly enigmatic. Significant portions of the canal remain well defined,
while other areas are only suggestive or seem to be missing entirely.
The Jernigan Canal apparently branches off the Mud Springs Canal in
a "T" structure at < N 32 49.659' W 109 49.170' >. Several smaller
rocks in the otherwise uniformly coarse Holocene valley fill soils
suggest a possible unexcavated "headgate" or similar diversionary
structure. Both canals in this area are not well defined. However,
seasonal dead wildflowers at times rather strongly reinforce this
likely routing.
The canal becomes better defined just west of the 4WD track at
< N 32 49.751' W 109 49.132'> and may even have a second parallel
channel at this point. Size is the typical one meter wide by 30 cm deep.
After crossing the track near < N 32 49.806' W 109 49.086' >, the
canal route seems to vanish entirely without a trace. Considerable
time and effort has been spent trying to find the projected missing
600 meters or 2000 feet of route without positive results.
The most credible canal crossing of the West Layton Road would
appear to be the modern waterbar at < N 32 50.215' W 109 48.898'>.
The potential route between here and < N 32 50.347' W 109 48.926' >
is rather vague but seems to be the only somewhat reasonable
"Ockham's Razor" choice.
There is a possible western canal branch at < %  N 32 50.364'
W 109 48.850' > leading to a possible partial aquaduct at
<N 32 50.347' W 109 48.926' > However, this structure is highly
enigmatic and could in fact be a historic wash crossing.
At < N 32 50.410' W 109 48.763' >, the canal is very close to
West Layton Road and amazingly near the adjacent Mud Springs
Canal. It is only slightly higher in elevation. Extreme length
measures were apparently taken to gain this exceptionally
modest height gain.
The Jernigan canal continues north in a well defined manner
and then suddenly disappears near < N 32 50.574' W 109 48.760' > .
A large "S" turn is anticipated at this point and sheet flooding is
a possible reason for the lack of on-ground evidence. There is no
obvious connection between this point and the continuing northerly
Mud Springs canal after its road crossing.
The Jernigan Canal resumes at < N 32 50.570' W 109 48.869' >.
There is a possible west trending cutout at this point dropping into the
wash. This may go to minor fields, may have been used for flow
regulation or desilting, or may not exist at all. The main canal is
well defined south of here and includes a large Mesquite tree mid
channel. Finding this portion of the canal proved quite difficult
because of a non-obvious and unexpected "U" turn when
crossing the wash from the west.
The canal makes another "U" turn in an obvious well hung
portion that includes a fairly long and deep cut at < N 32 50.564'
W 109 48.927' > It then routes northerly and drops into an apparent
French Drain type of structure that feeds some well defined apparent
prehistoric fields.
This east viewing photo  < >
shows a hanging portion of the canal just above the fields with the
tentative French Drain structure just off image to the right.

Present work that needs done on the Jernigan Canal...

   \267 Resolve the route over the two missing pieces.
   \267 Further interpret the possible headgate structure.
   \267 Verify the credibility of the modern waterbar crossing.
   \267 Determine the age and purpose of the potential aquaduct.

The |jAllen |jCanal
The Allen canal sources from Spring Canyon and presumably delivered
water to fields under the present Layton flood control dam. It is
potentially 9.6 kilometers or 6 miles long and has an average slope of
4.1 percent. However, this  surprisingly high figure includes a
significant drop over a mesa edge. Most Allen slopes are comparable to
the other hanging canals in the series. Portions have been convered by
modern cattle tanks and failed flood control dams. There is a rather
spectacular "Culebra Cut" that is far and away the deepest and longest
known excavation in the entire hanging canal series, approximating some
two meters deep, three meters wide, and over a hunderd meters long.
There are also more modest hanging portions and less deep cuts
apparently used to maintain grade largely independently of terrain.
Almost all of the known portions of this canal lie on Arizona State
lands. Access is generally difficult and largely limited to foot or
small recreational vehicles.
This canal has apparently been historically modified to create the
seemingly misnamed Hawk Hollow cattle tank and has also seen CCC style
water spreader construction features. Two segments of the canal remain
unexplored and its ultimate destination remains presumed but unknown.
Evidence of anquitity includes the spectacularly failed SCS Allen Dam
running roughshod over the canal without any apparent accomodation
whatsoever. There are also numerous mature barrel cacti midchannel on
the mesa. Plus the fill and spoil areas show highly consistent patina,
desert varnish, lichens, and caliche.
The canal Spring Canyoun takein point is rather obvious at < N 32
46.943' W 109 50.130' > . Erosion has rendered its present use
nonfunctional. This takein point seems to correspond to a modern
seasonal stream flow limit and is near the expectecd contact between the
Precambrian Mountain Schist and the Holocene Valley Floor fill. While
the canal has obviously been diverted to meet historic needs, the
reaches themselves appear to be largely devoid of any evidence of modern
tool use.
This image near the takein shows the typical size and construction
characteristic of most portions of most of the hanging canals. The image
also exhibits a rather strong "water flows uphill" illusion\274

< < >

The Hawk Hollow tank ( which is really in the Central Wash branch of
Spring Canyon ) represents a modern adaption with obvious tool use and
European style precision coursed masonry construction in its overflow
channel. At present, the area south of the tank remains unexplored but
is expected to yield no surprises. Similarly, the area north of the tank
remains unexplored. Satellite imagry in this area reveals numerous CCC
water spreader projects. Rock cobbles in this area are generally larger
and less uniform, leading to apparently cruder canal construction. There
is also a modest hanging portion where the canal "climbs" out of a wash.
The canal tracing can be resumed further North where a rather long but
fairly shallow cut was made to retain grade.

From here northward, the canal is usually quite easily followed.

Especially near < N 32 48.652' W 109 48.717' > Typical size might be a
meter wide by 20 CM deep. There are numerous mature Barrel Cacti mid
channel, suggesting a total lack of recent use beyond the Hawk Hollow
tank. None of the mesa reach seems to show the slightest evidence of
modern tool rework.
Only scant hints of possible canal routes have been found between the
mesa edge at < N 32 49.732' W 109 48.094' > and the Allen Resorvoir at <
N 32 50.022' W 109 47.702' > to date. Leaving a definite gap yet to be
resolved. The Allen reservoir clearly ran over the canal route without
regard to any use or accomodation whatsoever. Giving yet another example
supporting the prototype canal being prehistoric. This reservoir was
built by the Soil Conservation Service in the 1930's and its overflow
was possibly intentionally blocked in the 1950's. Which resulted in its
specatcular failure two decades later.
The watershed of the Allen Reservoir is quite small and significantly
lacking in mountain runoff, major springs or artesian sources. It is
possible that the Allen Canal itself served as an early primary or
auxiliary water supply source. However, the midchannel Barrel Cacti
would seem to pose contrary evidence. There are anecdotal claims < > that the resrvoir once
supported water ski recreation.
The canal is easily traced below the dam, leading to this moderately
hanging image just above the Culebra Cut at < N 32 50.133' W 109 47.870'

< > hanging portion just
above Culebra Cut

The white channel color is likely based on caliche related dissolved
solids. The few washouts in this area seem amazingly minor.
The Culebra Cut at < N 32 50.133' W 109 47.870' > represents an amazing
commitment of manual labor and transport resources. No other hanging
canal artifact approaches its scope. In retrospect, the Culebra Cut
seems to be much larger than the rest of the Allen system and of an
architecture significantly different from the higher mesa canal areas.
Reasons for this discrepancy are not entirely clear. But there seems to
be no evidence whatsoever of any modern use of this canal reach.
The canal continues westward beyond Culebra and remains fairly easily
traced. There is a rather complex double "S" where the canal crosses the
double tracked north south fence. The canal suddenly loops northward
when it crosses Central Wash near < N 32 50.133' W 109 47.870' > . Just
north of here, the previously obvious canal track vanishes entirely.
Possibly caused by sheet flooding or major wash rework.
While the Mud Springs canal is a reasonable distance further west, the
presence of minor hillocks and a somewhat rolling terrain largely seems
to preclude any connection. Instead, the canal is presumed to continue
northward. With a logical but unverified termination in fields presently
under the modern Layton Flood Control Dam.

Online auctions often will combine shelves or cabinets or

bargains. But you may not want or need the shelves or
cabinets and dealing with them can lead to excess shipping
costs and labor.

These can often be given to other bidders. Simple abandonment
may involve outrageous charges buried in the terms and conditions.

as always, read and understand before you sign any auction contract.

Another interesting alternative is an outfit called Habitat For Humanity.

These folks build low cost housing and have outlets where donated
building materials are sold in their ReStores, usually at bargain prices.
Clean empty auction shelves and cabinets certainly would qualify.
And there often is free pickup.

The |jShingle |jMill |jCanal
If the premise that virtually every drop of Northeastern Mount Graham
stream water was totally exploited by the hanging canal systems is valid,
then a prehistoric canal rather likely existed in the Shingle Mill Canyon
or Merrill Wash area. And might otherwise be conspicuous by its absence.
There is in fact a rather obvious abandoned historic canal called the
Minor Webster Ditch System present. Although of a somewhat deeper
vee construction, having evidence of modern tool use, and having an
atypical access road, a reasonable case can be made for adaption from
a prehistoric prototype. Total length would be approximately 3.2 kilometers
or 2.0 miles. While presently largely unexplored, the canal could reasonably
be expected to deliver water from the Shingle Mill and Merrill Wash
transition area to fields near the present Cluff Ranch headquarters of
Arizona Game and Fish. Approximately one-half of the historic canal is
quite obvious and easily traced and followed from the satellite images.
No hints of a canal, historic or prehistoric, have yet been found south and
west of the Mceniry Road crossing at < N 32 47.869' W 109 52.384' >.
There are, however, numerous CCC diversion structures in the immediate
area. This area is a floodplain and a case can be made for major and
possible distruptive flooding over time. A reasonable input point might
be at the transition between Shingle Mill Canyon and Merrill Wash,
perhaps at <N 32 47.327' W 109 53.401'>.
The historic canal becomes rather obvious just east of the Mceniry Road
at <N 32 47.869' W 109 52.384'> and is easily traced northward. Present
exploration ended near < N 32 47.869' W 109 52.384' >, with the canal
continuing to be readily extended northward. A modest hanging portion
of the canal can be reasonably expected further north, but has not yet
been field verified. The projected end use area was likely around
< N 32 48.769' W 109 51.988' >. Terrain in this area has been
extensively and repeatedly modified by farming activities and
more recent AGF projects.
Many thanks to historian George Hayes of Arizona Game and
Fish for his highly useful research input to this topic.

The |jRobinson |jCanal
The Robinson canal is presumed to be a historic rebuild and reuse of a prehistoric
original. The route is well marked on the topo maps and believed to originate in
Frye Creek near Frye Mesa Reservoir and originally deliver water to fields possibly
in the Robinson Flat area. Partial modern use apparently delivered water to the
Thorpe and Stowe stock tanks. Long dead but still extant remnants of parasitic
trees suggest fairly late continued use.
The "earlier" section of the Robinson Canal was treated separately, owing to

Got an email asking if Walsh Functions could not be used
for my Magic Sinewaves. The short answer is "not really"

Despite being an interesting and potentially useful digital math
construct, Walsh Functions never really got off the ground.
At one long gone time, they were the great white hope
for electronic music timbre generation.

Every Walsh sinewave generator I've seen demands a
weighted analog combination during synthesis
. This
clearly is a big time no-no for efficient power electronics.

In general, each and every math approach to anything
has one task it is particularly good at. In low pass filters,
you can do no better than Butterworth if the smoothest
pass band is your goal. Because Butterworth fundamentally
defines and demands the meaning of "smoothest passband".

Similarly, for flattest time delay, you use Bessel. For no
stopband ripple, Chebycheff. And the best you can possibly
do with both passband and stopband ripple, Elliptic. The
latter guaranteed to give you the fastest passband to
stopband falloff. By definition.

More on all this in my Active Filter Cookbook.

Similarly, my magic sinewaves define and demand
the maximum possible number of zeroed sequential low
harmonics for the minimum possible number of pulse edges.

In the same context of other functions being optimal
for other specific tasks, nothing better than Magic
is possible for this narrowly and specifically
defined task of max zero harmonics for min pulse edges..

A visitor to our website asked how to create a 0-100 random
number generator.

If the system is large enough to have any sort of language
associated with it, chances are there is a random command of
some sort. Such as the PostScript rand command, the random
command in my Gonzo utilities, or JavaScript's Math.random();

These days, a traditional hardware solution might not make too much
sense. Being better replaced by a PIC, the Basic Stamp, or the
Arduino from Radio Shack. Or pure software in the host.

You might have a choice of "real" random or "pseudorandom".

Ferinstance, you could run a high frequency clock through a pushbutton
to cause numerous overflows on a modulo 100 counter. Such
as this "modulo 36" older example. For best operation, the
pushbutton should be fully debounced.

If you do not want to press the button each and every time, the
chances are something else in the system ( such as a keyboard
or display scanner ) can advance a register to continuously
create new random seeds. A classic early example were the
RNDH and RNDL page zero slots on the Apple II.

Or, you might take a long shift register and exclusive-OR
two or four stages to create a long pseudorandom sequence.
But note that a pseurandom sequence will generate the
same sequence over and over again unless you reseed it.

Per this tutorial or this tap listing.

TTL Cookbook.

A reasonable guess for the "next breakthrough thing"
might be air conditioners.
The SEER ratings these days
are mandiated to be 13, with new units having SEER's as
high as 22 or so.

The only tiny gotcha is that the industry seems to have
internalized their gains
. The incremental cost of going
to a more efficient unit often may not amortize.

Probably because of ripping off subsidies.

But as this site tells us, theoretical SEER's can be
as high as 122 for normal areas and 46 for desert
Thus the potential for improvement can be
nearly a staggering 10:1

Four key factors got the efficiency to where we
are today: The scroll compressor, new refrigerants,
variable speed air handlers, and intelligent thermostats.

Immediate new gains can be made by going to
inverter compressor controls where the compressor
needs can be real time load adjusted.

Solid state or Peltier Devices are very unlikely to
have any close in breakthroughs, as they hit the
wall decades ago with their horrible efficiency.

A COP of 0.2 is hard to realize.

As shown here, a key Peltier problem is that a
unit might offer a 15 degree drop but have a
30 degree heatsink RISE above ambient.

For a net cooling loss. Thus, these devices seem to
me to be forever limited to such low power uses
as microscope slide chillers or thermoelectric
chip coolers. They are clearly worthless as beer
And totally unlikely to handle anything larger.

Instead, I would expect new breakthroughs to be
made by dropping costs of variable speed drives
and by dramatic reductions in thermal impedance,
boundary layer reductions, frost management, and
heatsink efficiency.

The latter similiar to yesterday's Blog announcement
or by way of similar MEMS techniques.

Along with fundamental changes in how HVAC units
are distributed and installed and sold.

June 30, 2012 deeplink respond

How fast is a river flowing at the shoreline? ZERO. Because
you cannot have a velicity discontinuity in most physical systems.

This is called the boundary layer problem and is it ever. IF the
boundary layer thickness can be dramatically reduced, all sorts of
efficiency improvements becomes possible in HVAC and cooling
or heating systems.

Despite its obvious overhype, this development would seem to be
a major new development in improving the efficiency of heatsinks.

It is likely that similiar "thin the boundary layer" reductions using
MEMS Techniques might dramatically improve HVAC efficiency

And possibly soon.

More often than not, anything you cannot use will end

I noted three interesting quirks in some of the latest online
only auctions.

Sometimes for a brief instance, the online bidders may be
given the opportunity to open bid at one-half the minimum
This is somewhat similar to waving your hand across
your chest at a live auction to get the bidding started with
a lowball offer.

And - disconcertingly - It seems that several online only
auctions are revealing your proxy prices above $100.

This shows up as a next required bid sometimes being
well above the expected next increment.

Which means your competing bidder no longer has to keep
trying to beat your proxy, since they know ahead of time
what is needed. On the other hand, the higher next required
bid may scare away potential bidders.

It seems to me that revealing proxies overall will reduce
seller income but increase bidder convenience

Also, any opening prices that are too high to interest bidders
are often cut in half
as the closing deadline approaches.

Benefitting from these quirks requires extreme attention to detail.

June 20 , 2012 deeplink respond

More and more auctions are going online only, with
Bidspotter and Branford leading the pack.

Some tactical guidelines...

Keep a list of usernames and passwords if you
are involved in more than one auction.

Proxy bid your max ONLY ONCE and do
so ONE MINUTE before any auto extension
trips. Do NOT bid further!

Your "max-max" may be slightly higher than your
"max" since the full proxy price is rarely paid.
Usually you will get the item for less or will
lose the auction. A "max max" price something
like thirty percent above your true max might
be an appropriate gamble.

Pre-register by at least two days.

Early in the auction, attempt to place a lowball
nuisance bid on a low value item to make sure
your bidder access is activated.

Base your maximum proxy price on your
TOTAL cost, INCLUDING shipping and
pickup, buyer's premiums, and sales tax.

Bit early items ONLY if closing the deal
makes sense BY THEMSELVES.

If at all possible, preview the auction.
Especially on "contents of cabinet"
and "contents of room" where by far the
best deals can often be found.

Create a "shopping list" ahead of time
with known item values and their interest
to you. Keep this onscreen during bidding.

Make sure pickup or shipping will not
end up an insurmountable hassle
before placing ANY bids .

Stay alert if you have interest in sequential
or near sequental items. Celebrating a
win may cost you one or more better ones.
Prices of identical sequential items often
go down as other bidders needs are met.

Dollar cost average if you get a few
early great deals. These may allow
you to offer more on later items.

If you have not made a $25 mistake,
you are not being aggressive enough.

Be patient! The best pricing and
deals will usually happen very late
in the auction. Because others may
have left, gotten what the want, or
have run out of money.

Craig's List seems to be turning into a highly useful

one or two useful hits per month. And an amazingly

A third party search called Search Tempest is enormously
useful, since it lets you view entire geographical areas

One tip: on higher populated results, always click on the
latest offering to view
, regardless of whether it is useful.
This color codes how far down the list you'll have to go on
your next search.

fairly well. Scanning about five per day.

So far, I have not had much luck with "proactive" want-
to-buy listings. But there is no reason they should not
eventually work.

It is super important to seek out only specialty industrial
that you have unique expertise in and can add
significant personal value added.

And to work in larger lots, preferably fifty or more items
per offer. It is also of utmost importance to stay away
from anything even remotely illegal
or of access or
interest to meth heads and such

It is also important to test each and every item that is
no longer in its original factory sealed package. And to
offer an unstated but unconditional guarantee on all
listed items.
Usually with no return needed.

This is a good place to find the value of industrial items.

Continuing the rough drafts of our upcoming field guides
to the prehistoric hanging mountain canals...


A newly reexplored group of spectacularly engineered prehistoric
"hanging" mountain canals appears to exist South of and above the
Safford Basin in Arizona's upper Gila Valley.

The canals appear to be agriculturally oriented and possibly date
from the 1360's late classic era. They apparently attempted to
exploit virtually every drop of Northeast Mount Graham
perennial stream water. And apparently had more than succeeded
in doing so.

At least fifteen canals are now verified with a total distance of at
least 40 miles. Twenty canals of at least 55 miles does not
presently seem a totally unreasonable extrapolation. Each and
every preannual stream shows moderate to strong evidence of
activity. Many are remarkably and consistently
and uniformily similar.

The canal system appears to be total and complete. Because
of system completion, it apparently can be considered largely
successful. No
evidence of incomplete canals under obvious
construction are presently known.

The engineering required appears to be exceptional and world
class significant. And certainly underappreciated. Several of
the canals
flow to this day. Albeit with modern adaption and

There are also apparently solid aquaducts, headgates,
"french drains", route switching, and multiple sources
and diversions present. Some
extreme cuts are present.
The "Culebra" cut on the Allen Canal is some six feet
deep, twenty feet wide, and many hundreds of feet long.
And would clearly represent a staggering amount of hand
labor. Other fairly deep and long cuts exist elsewhere in
the complex.

Extreme measures were apparently spent in maintaining
efficient slope. Even if it meant multiple "S" curves or
building a mile or so of
parallel canal simply to gain or
lose a few feet of elevation.

A hallmark of a typical canal would be its being partially
"hung" on the edge of a steep sided mesa. Such a
"hanging" canal has the
remarkable property of its slope
being largely independent of terrain. Thus leading to extreme
energy efficiency in which most labor and
effort went across,
rather than along, the canal constructions. The amount of
hang elevation can vary from a few feet to the better part
of one hundred.

Another hallmark of the canals is the often presence of a
rather strong "water flows uphill" illusion. In reality,
most known canal
slopes remain just over a consistent one
percent range. One that appears to have been exceptionally
carefully maintained.

The hanging mountain stream canals appear to be independent
of possibly contemperaneous lowland based Gila River
canals. They would seem
to have an advantage over the larger
canals in that the hanging canals are less likely to fail
catastrophically and would be much easier
and much faster
to repair.

Many of the hanging canals were apparently adapted by
Anglo and Spanish pioneers. Involving cement lining or
adding reservoirs and cattle
tanks. A strong case can be
made that most of these adaptions seemed to be of a
"steal the plans" and "dig out an old ditch" variety.

With very little of modern tools and techniques being
applied to improve the actual pre-engineered canal
route or construction. Almost
always, only a portion
of the original canal was adapted. With other reaches
remaining largely intact and unmodified.

The canal routes appear to be exceptionally attuned
to immediately local topography. And often made
use of highly unusual grade
situations. Of particular
note is the crossover between Ash Creek and the
Mud Springs bajada.

Evidence of the canal ages can be based primarily on
their purposefullness and extreme energy efficiency.
An efficiency demanded by a
total lack of horses or
wheelbarrows or Gradealls.

Age evidence can be based supplementally on their
lack of evidence of modern tools and techniques;
the presence of mature trees, cacti,
and shrubs mid
channel; the consistent desert varnish, caliche, and
lichens; weak to nonexistent aerial photography
compared to newer
structures; a generally "vague"
or "fuzzy" appearance; dams, roads, and fences
running roughshod over the system without any
regard to
use or accomodation; significant
"missing" portions; the presumed much higher
prehistoric population compared to the pioneer;
of later day adaption; extreme
differences compared to CCC architectural
techniques and purposes; routes largely unadapted
or meeing
modern needs; lack of respect or a
pioneer preservation ethic; possible CCC fingerprint
and tool foresnics; lack of mentions in pioneer
family histories; and the exceptional measures taken
in avoiding significant cuts and fills.

No evidence of survey tools have been recovered.
A speculative case can be made that the canal under
construction itself served as a
modifiable "water level".
In which a very small and easily modifiable exploratory
canal could initially establish a desirable slope.

The majority of the canal routes lie on Arizona State
lands. Several takein sources appear to be inside
Coronado National Forest. There
is some but very
little BLM or private landholder involvement.

All but one of the canals appears to be mountain stream
fed. There is one possible exception of an artesian
sourced canal. None of the
mountain streams are particulaly
large today, with average flows in the one CFS range
being typical.

The canal takein points appear to be largely consistent
with the last modern elevation of reasonably reliable
water flow. This tends to
correspond with the contact
between Precambrian mouontain gneiss and Holocene
lowland conglomerate fill.

The canals are largely devoid of artifacts or intermediate
use along the delivery portions of their reaches. Although
there is a highly
atypical field house or "wading pool" in
direct association with the mid reach of the Mud Springs
Canal. This enigma remains under study.

As is expected, the few potsherds found in weak
association include corregated, black-on-grey, black
on white, or red slipped tradeware.
And appear to
demonstrate an exceptional trading activity between
most major Southwestern cultures. Apparently including
Mimbres, Salado, Anazazi (or ancient pueblo
peoples), and possibly Sinagua.

Tentative working renames of the canals in counterclockwise
order are P-Ranch, Ledford, Henry's, Modern, Marijilda,
Tranquility, Twin
Boobs East, Twin Boobs West, Deadman,
Longview?, Riggs Complex, Robinson, Frye Mesa Complex,
Allen, Mud Springs, Jernigan, Shingle Mill,
and Lefthand.

A case can be made that the Mud Springs canal was an
earlier prototype. There are points along this canal where
the entire route can be
simultaneously viewed.

There are many examples in which a canal "climbs" out
of a wash to "higher" ground. As before, the involved
engineering appears utterly

It would seem difficult to imagine the needed technology
and engineering being imported from elsewhere. Owing
to the unique presence of
multiple small mountain streams
in the Safford Basin area. Which possibly suggests that
the engineering and technology largely evolved in

There are many layers of complexity to the Safford Basin
prehistory. Many of which are apallingly understudied and
underreported. These
include Gila River major lowland
canals, many thousands of agricultural grids, even more
mulch rings, numerous habitation sites and field
houses, aproned check dams, extensive tradeware
decorative pottery, other apparently ag related rock
alignments, and the usual odd point,
core, or knife, It
is not yet clear what spatial and temporal interactions
took place between these and the hanging canals.

My earliest exposure to anything remotely resembling a
computer was a useless IBM beastie and some analog
non-starters at otherwise superb Lafayette.

Followed by some BASIC timesharing.

But I guess my first foray into original and hands-on
programming took place on an Olivetti Programma 101.

Followed later by an Interdata 1 with a whopping 2K
of system RAM. And of course, the quantum leap in
going to the personal and incomparably stupendous KIM-1.

The first Olivetti project was a simple mortgage calcultor.
At that time, nobody knew the deep dark secret that by
tripling or quintupling up on utterly small early principal
payments, you could ridiculously shorten the loan time

and the amount of total interest paid.

The second project directly led to our Musician's Pitch
. in PE. The question to be asked was "What is
the best possible 8-bit sequence to synthesize an
equally tempered top octave music scale?

The subtle and non trivial answer was 116-123-130-138-

Equally tempered musical notes are separated by the
highly irrational factor of
1.05946309 in frequency.
Known to its many friends as the twelvth root of two.

AKA six percent if you ignore sour notes.

At the time, I thought I was doing unique and original
research. But MOS Technology had to be working on
something similar leading up to their MK50240. Which
had the unspeakable luxury of using a 239-253-269...
nine bit sequence instead.

And the JAES paper apparently appeared much later.

Modern synthesizers use a separate generator for each
polyphonic note.
The top-octave-and-divider scheme
used for electronic organs incurably lacked a richness
of locked together octave phasing and presented background
noise and crosstalk problems with all of the unkeyed
notes. Besides needing a keyer for each possible note.

I still overwhelmingly prefer to use PostScript as a general
purpose computing language. Particularly when stunning
graphics beyond world class are needed. But there are
times when strong interactivity or 64-Bit math are required.

And solutions such as JavaScript over HTML may be the
better choice.

I'd kinda like to include some quantization bargraphs in
the next version after the next version of our Magic
Sinewave Calculator
. Where interactivity and high
math precision are a must.

While there is no way in hell that JavaScript can even
remotely approach PostScript graphics quality, some
web solutions to bargraphs can be found here, here,
here, here, here, here, here, here, and here.

One route is to use bar images and change their
display width or height. Others involve CSS.

I'm not yet sure which way to go, but there should
be some sort of "steal the plans" solution.

Magic Sinewaves are a unique method of digitally
synthesizing the waveforms needed for solar panels,
electric cars, and industrial controls. They offer the
highest possible efficiency consistent with zeroing out
the maximum possible number of low harmonics.

Current work on our magic sinewaves consists of
removing some minor bugs from the latest update of
our ultra speed magic sinewave calculator. Something
is still not quite right with the quantization export code.

I'd also llike to add some quantized spectral displays
to the next calculator version. But first, the best way
for me to do a HTML bargraph has to be determined.
This is apparently not trivial.

The original magic sinewave hardware consisted of 8-bit
low end PIC chips. In which the clock input was used to
externally set the frequency. And fancy "factoring" tricks
had to be used to get 12-bit precision delays out of an
8-bit system. Which led to code complexity and some
"pinch point" issues.

But these days, we have alternate 16- and 32-Bit micros
at sane pricing. Which should allow direct synthesis of a
precision 12-bit delay. And should have enough internal
flash memory that both frequency and waveshape can
be generated inside the chip.

Ferinstance, fifteen delay values might be needed for a
typical magic sineave. If there were to be a hundred
amplitudes of a hundred frequencies, this would take
as much as 150,000 bytes of storage. Or much less
than what is reasonably available as flash today.

Development associates welcome.

I was susrprised that a scientific type living in east
Payson never heard of the Tonto National Forest
Seismological Observatory

It turns out the facility north of but halfway on the road
to Starr Valley is long gone
. And apparently now part of
a golf course in a slurb.

This was really a cold war facility to snoop on the evil
empire's nuke testing. Supposedly the instruments were
sensitive enough to have to compensate for a squirrel
stamping its feet.

Useful research was also done on measuring and
analyzing such things as sonic booms and surface dispersion.

The web does show some abandoned and grafittied instrument
bunkers. I'm not sure these still exist, given that the area is
now a wall-to-wall slurb.

The |jTranquility |jCanal
The Tranquility canal would seem somewhat atypical as it appears
to be artesian sourced, is only 1.6 kilometers or one mile long, is
"urban" subdivision located, and remains very much in need of
stronger proof of verifiable prehistoric origins.
The canal appears to start at an artesian source of N 32 45.599'
W 109 43.964'
and ends in the Cooks Reservoir of N 32 46.445'
W 109 43.678'.
Much of the canal reach lies on posted private
There remains considerable evidence of historic artesian
building/rebuilding at |/to N 32 45.599' W 109 43.964'/tx ,
mostly in the form of iron or steel pipes, headgates, and
diversionary channels. This is presently the presumed
location of a prehistoric canal takein as well. All
development appears to be presently abandoned.
Presumably because of a dropping water table.
At |/to N 32 45.599' W 109 43.964'|/tx , the Tranquility
canal comes amazingly close to the Eastern prehistoric
hanging canal feeder of the Labanon ponding area.
Approaching within 250 feet or 75 meters horizontally
and perhaps only 25 feet or a mere 8 meters vertically.
However, the Eastern Lebanon feeder is at a distinctly
higher elevation and the two appear totally unrelated.
There is a significant cliff between the two water channels.
This image just south of the Annes Ranch Road shows
a curious mix of prehistoric and historic canal features\274
< >
The channel is "hung" in the normal prehistoric manner
and appears to be of minimum energy construction. But
there also is an access trail and a thin puddled and lager
aggregrate concrete liner remarkably similar to the
Marijilda Canal historic improvements. Unlike virtually
all of the prehistoric canals, the routing goes through a
modern "urban" housing development and crosses
posted private property.
The Annes Ranch Road at |/to % N 32 45.881'
W 109 43.769'
|/tx runs roughshod over the canal,
completely oblitering it without any regard whatsoever
for continued use. The date of road construction is
presently unknown but assumed to be in the 1960's.
Just north of this point, the puddled large aggregate
concrete lining appears to be taking a parallel "short cut"\274
< >
Should this rerouting in fact be verifiable, it would
strongly support the usual "steal the plans" historic
modification  of a prehistoric origin. Note also the
"dead flowers" that seasonally tend to verify routes.
The canal becomes indistinct where it crosses West
Lebanon Road but shortly becomes obvious on Acme
Mapper further to the north. When the canal crosses
the Schmoller property yet further north at
|/to N 32 45.599' W 109 43.964'|/tx , it no longer has any
concrete lining or access trail. And very much appears
exactly like any of the other prehistoric hanging canals
in the Safford Basin system. Locals in this area even
call it "the old indian canal". This reach is quite obviously
and fairly easily explored.
The Tranquility Canal presumably ended in fields under the
Cooks Reservoir. This reservoir presently appears unused.
Tranquility Canal topics needing further investigation\274

\267 Seek additional proof or disproof of prehistoric origins.

The only tiny thng wrong with the pv breakthrough of
the week is that they consistently seem to have a half
life of 6.99 days.

There's a whole other world of dye based solar that
can involve super cheap chemicals and simple structures.
Their only problems are that they normally only last
a few days at most before self-destructing.

These are sometimes called Gratzel Cells.

Some of the dye based problems have apparently
been eased with this new development that substitutes
a solid for the liquid electrolyte. And dramatically
lowers certain materials cost.

Efficiency is in the ten percent range. While there is an
obvious tradeoff between cost and efficiency, few people
realize that a five percent efficient pv cell is totally worthless.

First because only half or less of the systen cost is itself
in the cell, and secondly because the required areas
and structures skyrocket leading to amortization issues.

As previously mentioned, improvements in Acme Mapper
have shown some curious rock alignments on Frye Mesa
that would appear to be prehistoric canal related.

It is never a good idea to let speculation run rampant over
the hard facts on the ground, but a possibility exists that
a Frye Creek canal system is real and could represent
yet another crown jewel of the dozens of prehistoric mountain
stream hanging canal systems of the Safford Basin.

Both the Robinson Canal System and the Riggs
Complex further downstream need a water source
and Frye Creek would seem probable. The modern
water pipeline appears to have a totally different
route further south and more in the canyon bottom.

Obvious CCC involvement in the alignments would
seem to be busywork "targets of opportunity" on
existing structures.
Just as with the Deadman
prehistoric canal, the route appears to consistently
be along the highest mesa slope. Any attempt to
use Frye Mesa itself as a watershed would likely
be lower and further north. Similarly, sourcing
from Spring Canyon or even Hawk Hollow would
appear unlikely as Frye Creek is far more obvious.

All of which suggests the highly speculative premise
that an incredibly sophisticated canal was prehistorically
present between the bottom of Frey Creek Falls and the
rock alignment structures on Frye Mesa

Proof is presently lacking, and initial and recent rework
of the reservoir may have masked the existence of
such a canal. One hint of a whiff of bare fumes of a
possibility appears here and certainly needs field

Probably the best instrument to "solve" the problem
of measuring prehistoric canal slopes is called a
self-levelling exterior laser level. While these cost
$400 to $1000 each, they sometimes show up for
much less at auctions. Presumably they are rentable.

These are a laser on a pendulum with a rotary motor.
They produce a rotating beam that is dead level so
long as they are minimally set up. Range of a quarter
mile is reasonably obtained. More at night.

They also should be useful to find missing portions
of a canal by noting that half the distance would
likely occur at half the elevation between the
missing ends.

And that elevations above the inlet and below
the outlet can be categorically excluded.

Continuing the field guide to the Mud Springs Canal.
Previous coverage appears here...

% < > % mid point below dam

% < > % troll house mystery structure

A rare and curious structure that appears intimately associated
with the canal lies just South of the 4WD track crossing at
( % N 32 49.522' W 109 49.368' )\274
< > % troll house mystery structure
The structure can be variously ascribed to being a field house or a
"wading pool". It is circular, three meters in diameter, and presently
half a meter deep. Its basal elevation is apparently flush with and
one meter from the canal proper. Its purpose remains enigmatic.
Tentative name is the "troll house".
The Mud Springs canal continues eastward, just north of the
4WD track until it reaches an apparent "Tee" junction that is
possibly the inditial diversion point for the Jernigan Canal.
There are a few small rocks buried in the otherwise southern
dirt sidewall at this point that suggest a headgate structure.
"Dead Flowers" are sometimes a fairly unique but highly
seasonal marker for canal routes in this area.
After crossing a larger 4WD track to the east, there is a split
that appears to provide a short feeder to a more modern small
cattle tank. This tank has surprisingly dense brush content.
The tank's origin and actual water supply presently remains
unexplained. The Mud Springs canal tends northward and
eastward from here and remains somewhat dim and rather
small but fairly tracible for the better part of a kilometer.
In general, there are very few artifacts associated with any
of the hanging canals. But in this area, very rare and quite
sparce potsherds can occasionally be found. Although not
in direct association. These are typically late classic
tradeware, often corregated or red slipped. As is typical for
the entire Safford Basin, the varieties suggest exceptionally
strong trading patterns between the dominant Southwestern
The canal seems to totally disappear between N 32 49.826'
W 109 48.955' and N 32 50.296' W 109 48.597' Possibly
because of sheet flooding or simply looking in the wrong
place. There also seems to be a possible short canal
segment at a totally unreasonable |/to N 32 49.735'
W 109 48.932'|/tx that presently defies explanation.

Further east, the Allen canal approaches within a
kilometer but appears "blocked" by small rolling hillocks.
No evidence of a more southerly direct canal route down
Hawk Hollow has yet been found and is presently deemed
Once relocated northerly, the canal remains fairly
traceable, although a portion of it has clearly been
trashed by an offroad bike track. Things get somewhat
dim near the major east west fence but renew
themselves nicely further north. At |/to N 32 50.556'
W 109 48.631'|/tx , the canal goes into a hanging mode
and is remarkably white. Most likely owing to caliche
deposits. The canal crossing of the main West Layton
road is fairly obvious but heavily erroded. There is a
distinct ocotillo on a small slope to the east.
Curiously. the Mud Springs canal and the Jernigan
canal remain quite close together in this area. Despite
their apparent intentional separation a full two
kilometers earlier.
Near |/to N 32 50.556' W 109 48.631'|/tx , the Mud
Springs canal becomes wider and quite easily traced...
< >
Nearly the entire route of the canal can also be viewed
from this point. Patina and desert varnish here would
seem to strongly support a prehistoric canal origin.
Frustratingly, the canal seems to vanish directly to the
north. With the most likely explanation being it lying
|/to under|/tx the obvious 4WD tracks. Terrain further
north is highly disturbed, including flood control
strucutres, a cemetery, trash dumps, offroading,
and power lines. While there are no obvious field
candidates, the canal route at this point is remarkably
close to ultimately merging with lowland Gila River
based canal systems.
Considering the stupendous effort that went into
canal construction and maintenence, a well defined
and obvious purpose must surely have existed.

Despite all the "apologist" publications that think they see
a future in books, I remain firmly convinced that the sudden
and complete demise of books will happen faster and more
spectacularly than anyone could possibly imagine.

No, decent readers are not here yet, and yes, the ludicrosities
of DRM and copyright have not yet been blown aside. But
it is just a matter of time. And ebooks are already outselling
dead tree ones by an ever expanding margin. The key point is
that there are clearly fatal flaws in books as an info
distribution method.

Flaws that are utterly and totally bypassed by electronic
media distribution. Let' s start with two subtle ones and
then go on to the obvious...

The first is the dirty little secret of the book industry:
Because of the Thor Decision, your federal government in
their infinite wisdom pays publishers to shred books.
fact, more books have recently been shreded that were
destroyed during the entire dark ages.

Overwhelmingly so.

This happens because the IRS ruled that back inventory
has to be carried at full value, rather than its scrap or
remainder value. Thus, any book that drops even a
little bit in current sales popularity gets destroyed and
becomes termnally unavailable

The second and not too unobvious secret is that students
are pissed over dragging around backpacks
. And a revolt
against at least the heavier of them would seem in the offering.

Going to the more obvious, books cannot be full text
searched. Books lack links. Adding color and images to books
is expensive, but virtually free with electronic distribution.
Many books never sell and have to be destroyed. It takes
time and energy to haul books around or store them.
Books can't
easily be read out loud. Most books are only read once.

The total energy waste and carbon footprint of books
utterly and totally overwhelms that of what goes into
the readers. While some quote a "twenty books to pay
for one reader's environmental impact", the average
reader can eventually be expected to provide access
to thousands or tens of thousands of titles.

An utterly overwhelming superiority.

Electronic media is instantly available 24/7. Its storage
space and volume is negligible. Prep time is ridiculously
shorter and simpler. Revisions, updates, and corrections
are trivial.

A brick and mortar bookstore at best can stock something like
5000 different titles in modest quantities. But even the
smallest and sleaziest of online suppliers today can provide
millions of titles in unlimitied numbers of copies. And that
is before the upcoming petabyte revolution where all books
can be provided all at once on a single thumb drive.

Acceptance of an eBook for publication is a certainty. As
opposed to a dead tree publisher who shall remain unnamed
who sat on one of my titles for over a year and then rejected
it because it was "not timely"

There's finally accumulating outrage over scholarly pub
houses charging utterly outrageous prices for research that
was paid for by your tax dollars in the first place. Open
source publication is now well on the way to becoming
inevitably dominant.

On the other side of the fence, Book-on-Demand publishiing
largely arrived stillborn. Its window has slammed shut. Owing
to outrageous costs and the key problems of economical trimming
and binding having never been addressed, let alone solved.

over into the Mud Springs Bajada and ultimately delivers water both to the
Jernigan Canal and to apparently fulfill yet unresolved needs in the Central
Cemetery area or even within the Gila basin flatlands themselves. Total
primary canal length is projected to be 6.0 miles or 9.6 kilometers. Of which
two thirds have now been reasonably field verified.
A case can be made that Mud Springs could have been the initial or prototype
on which all of the other hanging canals were based. The reasoning being
that from location |/to N 32 |47.492' W 109 51.228'|/tx , the |/to entire length
of the canal can be viewed at once|/tx , planned, and possibly surveyed. No
other known area prehistoric hanging canal seems to permit a one point
total viewing.
The Ash Creek takin is believed to be just within the Coronado National
Forest at |/to N 32 47.247' W 109 51.272'|/tx . The takin is not yet
explored and likely has been obliterated by long term flood damage.
A significant hanging canal can be anticipated in heavy brush on the
east canyon wall between the takein and the crossover saddle.
This reach also has not yet been located. Finding the actual route
may prove difficult.
The saddle point |/to N 32 47.492' W 109 51.228|/tx at which the
canal crosses from the Ash Creek drainage to the Mud Springs
bajada watershed appears to be remarkably well chosen from
both a minimum energy expenditure and a hydraulic engineering
standpoint. The crossover also appears to be topographically
unique with no reasonable route alternative. The canal at this
point is one meter wide by 30 centimeters deep. The channel is
reasonably and uniquely defined by its rock borders but is not
exceptionally obvious here.
The 4500 foot or 1.4 kilometer reach northward between the
saddle point and the Mud Springs Corral at |/to N 32 48.191'
W 109 50.360'|/tx has not yet been located. No significant surprises
are expected. This reach is projected to be reasonably findable
over much of its length and to include minor hanging portions.
The route is presently expected to be largely along the western
periphery of the Mud Springs Bajada. A resumption of the well
defined canal is easily viewed somewhat west of the corral
access road, again at |/to N 32 48.191' W 109 50.360'|/tx and
is easily traced a significant distance to the north.
The canal crosses the Mud Springs access road at |/to N 32 48.417'
W 109 50.274'|/tx . Which, coincidentally, was the initial
rediscovery point of the Mud Springs Canal route. A west
trending side diversion channel appears to be located at this
point. Whose apparent goal may have been to dump excess
water into a nearby wash, to adjust flow, or to aid in silt control.
There are also hints of apparently not well developed grids, rock
alignments, and possible smaller and ill defined water channels
somewhat north of this point and east of the access road.
Perhaps in and around the |/to N 32 48.836' W 109 50.350'|/tx area.
From the road crossing, the canal is easily traced northward,
eventually ending up in association with some rather obvious
CCC water spreading projects. The CCC architecture is
distinctly unique and almost always is routed across, rather
than along any canal or wash channels. There are many dozens
of CCC project examples in the area.
Eventually, the canal ends up in a brushy wash bottom and
becomes difficult to trace. But somewhere near |/to N 32 48.793'
W 109 49.969'|/tx , the canal begins a rather significant,
distinctly obvious, and superbly spectacular "climb" out of
the eastern wash terrace face. The engineering involved in
this task seems most impressive. Once back "up" in the
flats, the canal becomes indistinct and difficult to trace. At
a significant east-west fence, the canal is believed to cross
a short distance west of a unique triply "rock weighted"
wire reach. Access to this point is a not overly difficult
southwesterly hike from the end-of-track flood control
barrier at |/to N 32 49.049' W 109 49.664' |/tx . Besides
the GPS locations, a useful process would be to "find
the fence" to the southwest, then "find the weights". The
significant hanging portion will then be a short distance to
the southeast.
North of the major east-west fence, the canal becomes rather
indistinct. But eventually makes a sweeping "S" turn to
maintain grade. The canal resumes obviousness and easy
tracability somewhere near |/to N 32 49.098' W 109 49.887'|/tx .
At this point, there is a ten inch or 25 centimeter diameter
mesquite tree squarely in the canal mid channel. Which
strongly suggests a possible prehistoric origin for the
canal's origin. The tree has not been cored, owing to augers
being exceptionally easily damaged by such desert hardwoods.
From the Mesquite tree, the canal is easily traced northwards
nearly to the largest flood control dam in the area at
|/to N 32 49.415' W 109 49.459'|/tx . There is a short cut nearly
a meter deep where the canal exits a ridge. The canal appears
to go through several architectural variations in this area,
owing to topography and the problem of maintaining reasonable
grade. There are also extensive and enormous CCC or SCS
side channels present near here, along with possible actual
canal rework. Whose apparent purpose was to route flood
waters into the flood control dam. These are presumed to be
modern and date from the 1930's. The canal itself seems to
route somewhat west of the 4WD access trail. The canal at
this point appears somewhat smaller than its earlier and later
reaches. And might in fact be diversionary to separate fields
with the main channel buried or modified under newer construction
and rework.
|/to The flood control dam apparently ran roughshod over the canal|/tx ,
obliterating its route under silt fill and making no apparent
accommodation whatsoever to preserving or using the canal
channel in any manner. At present, there is a major and
unrepaired blowout in the lower dam wall that precludes its
intended use. Exploration of this blowout would appear to be
extremely unsafe and is definitely not recommended.
The canal is easily traced quite a distance from the dam face
southward and eastward. It initially begins yet another hanging
wall climb "up" the north wash wall. In reality, all of the
"climb" or "water flows uphill" portions strictly maintain an
optimal |/to downward|/tx slope in the one percent range.
The sheer brilliance of using a hanging canal for extreme
energy efficiency and to force its slope to be largely
independent of terrain cannot be overemphasized.
Here is an image near the mid point of the Mud Springs Canal...

< >

This reach is somewhat atypical in that it is wider and shallower
than most portions. The SCS flood control dam dating from the
1930's can be clearly seen in the background, along with its failure
blowout. The dam crosses the canal somewhat north (right) of the
blowout. And does so without any regard or accomodation
whatsoever. Neither adding to, removing from, or preserving any
flow possibilities. Also viewable is the Mud Springs Bajada,
appearing as a large triangle "pointing" to the also visible upper
Ash Creek drainage. About three miles or 4.8 kilometers of the
canal are more or less visible.
The scope and magnitude of the hydraulic engineering can be
appreciated by noting that this is one half of one of something
like twenty hanging canals in the total system. It appears that
a consistent attampt was made to totally exploit every possible
drop of Northeastern draining Mount Graham stream water.
Note that the canal goes |/to uphill|/tx into the picture. Despite
the illusion of climbing "up" out of the wash from the base of
the dam. Such "water flows uphill" illusions are quite common
elseware in the local hanging canal systems. In reality, a
carefully controlled slope often approximating one percent is
consistently made.
Note further that mid-channel brush strongly suggests no
recent use. Note also the exceptionally uniform patina, desert
varnish, and ( sometimes ) lichen patterns. Strongly
suggesting no recent canal wall or spoil bank modifications.
At this point, the canal appears to have a moderate fill that
could be water borne silt or aeolean dust.
A rare and curious structure that appears intimately associated
with the canal lies just South of the 4WD track crossing at
( N 32 49.522' W 109 49.368' ) The structure can be variously
ascribed to being a field house or a "wading pool". It is
circular, three meters in diameter, and presently half a meter
deep. Its basal elevation is apparently flush with and one meter
from the canal proper. Its purpose remains enigmatic.

Doing a Newton's Method solution for our Magic Sinewave
can be tricky for Delta Friendly sinewaves.

Because pairs of edges have to track to guarantee compatibility..

Variations on this sneaky trick seem to be useful: During a Newton's
Method itertion, substitute a single new parametric variable for each
pair of tracking old ones.
Convergence should remain the same.

Ferinstance, say we were exploring this possible new wrap map..

.     XXXXXXXXXXXXXXX       XXXXXXXXXXXXXXX       6   5    60-30     
.    X               XX  XXX               XXXX  1 2 3 4    0-30

With a new variable qa, let p1s = (qa - 30)   and p7s = (qa + 30)

Eventually with our "real" Fourier calculation, we will need
cos(p1s) + cos (p7s)  and similar multiple terms. Find the qa parametric
variable equivalent...

cos (qa - 30) + cos (qa + 30) =
cos(qa)cos(30) + sin(qa)sin(30) + cos(qa)cos(30) - sin(qa)sin(30) =
cos(qa)cos(30) + cos(qa)cos(30) =
1.735*cos(qa) for leading edges of p1s and p7s

You can now write similar equations for qb through qh.
Some will be positive, some negative.

The "parameterized" similar equations to be Newtons Method
solved would end up as...

cos(qa+t) -cos(qb+u)+...cos(qg+y)-cos(qh+z) = ampl*pi/(4*1.735)
     ( similar 5,7,11,13,17,19,  and 23 harmonic equations = 0 )

where the q's are known numbers from the previously best guress
and the variables t through z are to be solved via Gauss Jordan
to produce an improved guess for the next pass.

Some related techniques can be explored by viewing the underlying
JavaScript code used in the actual calculators.

There's got to be a cache to it somewhere. A maddeningly

Apparently .JPG images are being saved and reused to speed up

Stainless steel is a wildly inappropriate choice of material
for any electrolysis device where energy conversion efficiency
is important. Because of the hydrogen overpotential of iron
and chromium in SS alloys. Hydrogen overpotential simply burns
up incoming energy without performing useful conversion.

The "rusty" low energy passivated and low effective area surface
also does not bode well.

For this reason, "real" electrolysis devices to date ( as opposed
to web scams ) have demanded platinum electrodes. Not only
platinum, but a special form called Platinum Black that needs
renewed over and over again.

In a new discovery announced here and discussed here, a
"nanosheet" microcatalist has been developed that offers near
platinum performance
with much lower cost materials.

Which still does nothing for exergy, which tells us that
electrolysis from high value electrical sources such as
grid, pv, or alternator flat out ain't gonna happen. Because
a kilowatt hour of electricity is ridiculously more valuable
than a kilowatt hour of unstored hydrogen gas. The process
is thus pretty much the same as 1:1 exchanging US dollars
for Mexican Pesos.

Heathkit has once again folded, presumably this time for
good. Per this analysis and this discussion. This time around,
much of the blame can likely be placed squarely on the utter
cluelessness of their entire educational computing division.

Even worse, takedown notices have been posted to most free
web providers of legacy Heathkit info.
Flying in the face of the
standards long set by HP and Tektronix in carefully releasing all
legacy product info to the public domain.

And the once hearalded intended rebirth of Popular Electronics
magazine seems to have completely fizzled.

Hobby electronics peaked many years ago. It died for many
reasons. There no longer was any savings in kit construction.
Parts got small, complex, sensitive, and difficult to handle with
home shop techniques. Testing and debugging became a nightmare.

As did the ability for doing bleeding edge things on the cheap.

New diversions arrived, first in computer software, video games, and
then in web resources and then in social networking

Ham radio became a quaint and ludicrous geriatric parody of its one
time greatness. First because of CB and termnally because of mobile

But I feel the hidden cause of hobby electronics virtually disappearing
was the evil empire going "poof".
By bye. Gone. Nyet.

Community college electronics courses were predicated on guaranteed
jobs in aerospace for their graduates. Which completely vanished.
So the programs and entire departments were simply cancelled.
High schools shortly followed suit.

In some cases because the football team needed the money.

A minor backwater of hobby electronics remains. Available publications
include Circuit Cellar, Make, and Nuts & Volts. Such firms as Marlin
, Circuit Specialists, Electronic Goldmine, and others still cater to
an ever- and shockingly- shrinking audience. As do our own eBay sales.

Some kit suppliers remain, such as Sparkfun, Adafruit, and Evilmadscience.
And the Steampunk folks must be up to something, although it is not
clear exactly what. New Santa Claus Machine people are certainly
emerging here, here, and here.  

No definitive complete source of PE and other reprints seems to exist.
But a few random reprints can be found here and here.

Update: See American Radio History for mind blowing coverage.

Jeff Duntemann has revived the Carl and Jerry series. If brought
up to date, though, Carl would be a hated gazillionaire and Jerry would be
relearning to tie his shoes, owing to a slight drug overdose mishap.

Michael Holly has a SWTP tribute page with quite a few classic reprints,
and I have many of my classic reprints freely available.

The rate at which additional classic hobby electronics stuff can be added

I was chasing down some rumors of a local Apache Tears
field. And concluded the info was not yet good enough
for our Gila Dayhikes library. It is supposed to be south
of the San Francisco river above Cliffton. But I find it
strange that none of the "usual suspects" mention it at all.

Obsidian points and knives are quite rare in local prehistory. This
would seem unlikely if an obvious nearby field existed.

Not too long ago, I did check into the Bluebird Mine reference
in MinDat. But all I found was some exceptionally low quality
obsidian outcrops
. Awful, even.

Meanwhile, there is a web scam going on where most of the
Apache Tears being sold are really glass nodules being mass
produced in Indonesia via industrial processes.

One of the traditional best locations for smoky translucent tears
had been the perlite beds a mile SSW of the Superior Arizona airport.
But access was somewhat restricted the last time I checked.

We still have some fist sized specimens from way back when kicking
around somewhere.

There's also an extensive field of opaque tears a mile southeast of
the Burro Creek bridge, in the flat mesa just south of the highway.
Also check out sometimes excellent swimming in Burro Creek and
a nearby warm spring a
mile further west .

A review of our present "flavors" of Magic Sinewaves can be
found here. And their ultra fast calculators here.

At present, only one "style" of three phase delta friendly Magic
Sinewaves has been developed. Per this "wrap map"...

-----XXXXXXXX--------XXXXXXXXXXX---   60-90
-----XXXXXXX--------------XXXXXX----------   60-30
--------------------X--------XX ------------XXX----    0-30

This example zeros out the first 22 harmonics, offers full three
phase compability, and needs only one-half the storage of a
general Magic Sinewave. But a comparable Best Efficiency
seven pulse Magic Sinewave would zero out the first 28
harmonics and thus is more efficient at trading out zeroed
harmonics for pulse edges. But lacks delta friendliness.

The rule on the wrap map is that you can have zero or
two pulses in any column
. But not one or three. This
is required to not have to rewire three phase motors,
double the drivers, or introduce circulation problems.

The "missing" earliest pulse was chosen to allow some
processing time after a zero crossing for amplitude or
frequency updates.

I still do not know if there are any fundamental reasons
why these two alternate patterns should not work. But any
previous results have been disappointing...

-----XXXXXXXX--------XXXXXXXXXXX---   60-90
-------XXXXXXX------------XXXXXX----------   60-30
-----X-----------------------XX ------------XXX----    0-30

or this eight pulse version...

-----XXXXXXXX--------XXXXXXXXXXX---   60-90
-------XXXXXX--------------XXXXXX----------   60-30
-----X-------------X--------XX --------- --XXX----    0-30

The "water powered car" continues to run rampant on the
web. Overpriced kits are now available that let you conclusively
prove the bogosity to yourself beyond a shadow of a doubt.

Here's a summary of why the concept is not even wrong...

1. What part of "Gross and Egregious Fraud" don't you

2. A fundamental thermodynamic principle called exergy
    absolutely GUARANTEES that hydrogen produced from
    high value grid, pv, or alternator electricity flat out ain't
    gonna happen.
For the simple reason that a kilowatt hour
    of electricity is ridiculously more valuable than a kilowatt
    hour of unstored hydrogen gas.

3. There are EIS or Electrochemical Impedance Spectrocopy
    instruments readily available. These "run the experiment"
    many millions of times daily with uniformly negative results.

4. The resonant frequency of water is ONE MILLION TIMES
    higher than proponents claim, applies only to water vapor,
    and is not in any manner overunity.

5. Stainless steel is wildly inappropriate for hydrogen production
    devices because of the hydrogen overpotential of iron. and
    because of its low energy and low area passivated surface.
    Special Platinized Platinum Black normally is required for
    efficient devices and demands careful repeated renewing.

6. Because of Faraday's Law, only the Fourier Series direct current
    term of any complex pulse waveform can contribute to electrolysis.

    High frequency ac components primarily create bunches of waste
    heat and inefficiency.

7. It is trivially easy to mismeasure the energy in pulse waveforms.
    So much so that this is Beginning EE Student Blunder 001-A.
    Such measurement is almost always ridiculously low.

8. It is similarly trivially easy to mismeasure that actual dry
    STP hydrogen content in any vapor. Such measurement is
   almost always ridiculously high.

9. Surprisingly, electrolysis can in fact be up to one sixth endothermic
    and can produce "runs cool" effects. But such operation only can
    happen at very low and unamortizable production rates.

Curiously, the Ohio trial court fraud proceedings have never been

Over the years, my Magic Sinewave calculators have gone
from excruciatingly slow to nearly instant. The ongoing
debugged version appears here, while a yet-to-smooth-some-
rough-edges fancified code appears here.

The basic problem is to solve math equations similar to these...

cos ( 1*p1s ) -cos( 1*p1e )+…+cos( 1*p7s ) -cos( 1*p7e ) = ampl* pi/4
cos ( 3*p1s ) -cos( 3*p1e )+…+cos( 3*p7s ) -cos( 3*p7e ) = 0
cos ( 5*p1s ) -cos( 5*p1e )+…+cos( 5*p7s ) -cos( 5*p7e ) = 0
cos ( 7*p1s ) -cos( 7*p1e )+…+cos( 7*p7s ) -cos( 7*p7e ) = 0
cos ( 9*p1s ) -cos( 9*p1e )+…+cos( 9*p7s ) -cos( 9*p7e ) = 0
cos (11*p1s)-cos(11*p1e)+…+cos(11*p7s)- cos(11*p7e ) = 0
cos (13*p1s)-cos(13*p1e)+…+cos(13*p7s)- cos(13*p7e ) = 0
cos (15*p1s)-cos(15*p1e)+…+cos(15*p7s)- cos(15*p7e ) = 0
cos (17*p1s)-cos(17*p1e)+…+cos(17*p7s)- cos(17*p7e ) = 0
cos (19*p1s)-cos(19*p1e)+…+cos(19*p7s)- cos(19*p7e ) = 0
cos (21*p1s)-cos(21*p1e)+…+cos(21*p7s)- cos(21*p7e ) = 0
cos (23*p1s)-cos(23*p1e)+…+cos(23*p7s)- cos(23*p7e ) = 0
cos (25*p1s)-cos(25*p1e)+…+cos(25*p7s)- cos(25*p7e ) = 0
cos (27*p1s)-cos(27*p1e)+…+cos(27*p7s)- cos(27*p7e ) = 0

Each pair of terms can represent the Fourier Series of one
unity amplitude pulse having a sought after starting and ending
These equations are unlikely to have a direct solution.

Instead Newton's Method gets used in which you make a guess,
find the slope to zero, and then make a better guess
. The
process often rapidly converges here, usually beyond twelve decimal
places in five or fewer passes.

A really sneaky trick gets used to dramatically simplify and
speed up the equation solution. Consider this trig identity...

cos (a+x) = cos(a)cos(x) - sin(a)sin(x)

which is true everywhere for all a and all x. We already
know a from our previous guess, so it is a constant.
We also can restrict a to the first quadrant without any

Now, if our guess was good ( or"better" ), x will be a
very small number
. The cosine of x will be very close
to unity, so call it one! The series expansion of sin(x)
is x - x^3/3! + ..., so you can approximate sin(x) = x for
very small angles. Reducing the above equation near
x = 0 leaves us with...

cos(a+x) is roughly cos(a) - x*sin(a)

There seems to be emerging interest in a new Lithium-Air battery
technology. Vaguely comparable to the zinc-air scheme used
on hearing aids and elsewhere.

The big advantage is a potential energy density comparable to

presently available. The big disadvantage is that there are
serious and major problems yet to be resolved.

developments here and slashdot comments here.

There are two related electric car problems that may prove
unsolvable. If you try to charge an electric car battery rapidly,
the voltages and currents needed become absolutely ludicrous

And if you exchange batteries, you triple ( or worse ) the cost

The new high resolution imagery from Acme Mapper may

Yeah, there clearly is some CCC involvement, but this may

Industry uses three phase power because power flow is
continuous, wire and iron are less, there is less noise and
vibration, and motors start and reverse more easily.

But home electric service is normally single phase center
tapped 220 vac. Which creates a problem if you have one
larger three phase motor in your shop or wherever.

Traditionally, a beastie called a three phase rotary converter
was used. This was sort of a motor generator that was single
phase powered but produced three phase outputs. While
these remain available, the costs typically start above $500.

But these days, there is a better way. Called a VFD or variable
frequency drive
. These solid state devices are available for
$200 or less and are much smaller. They also can sometimes
let you vary your motor's speed as well. Allen-Bradley is
one supplier. Automation Direct is one discount source.

Some VFD's are single phase powered, while others are three
phase powered. It is obviously important to select a unit
that is single phase powered.

"Truth is stranger than fiction" gets even more bizarre 
when you wander into Western New Mexico. 

The Brushy Mountain Radar Station is South of Mule 
Creek at the end of a secret mountain laboratory road
whose access is easily controlled. It likely started life as a 
cold war facility and presumably still sees use for drug
interdiction activity.

Little known is that it includes oversize kitchen and
dormitory facilities.
It was supposedly used as a remote
retreat by both the Kennedy and Johnson presidental
administrations. Since then it occasionally has seen such
mundane uses as BLM team building excercises.

BUT and IF you needed to stash some super secret stuff
( such as, say, some extraterrestrial aliens ), the facility is
virtually ready to go.

Even stranger is nearby Terrortown, once known as Playas.
This began as a company town for a long defunct smelter
and was bought by a New Mexico school and funded by
the Department of Homeland Security for a training
facility for counterterrorism and urban hostage situations.

Truth can certainly be stranger than fiction. As a bunch 
of Gila Valley happenings over the years can attest.

One of the most blatant scams was the McEniry Tunnel,
a scheme to tunnel all the way through Mt. Graham. 
The gold and silver could simply be scraped off the ceiling
into ore cars, greatly simplifying extraction. At the same time,
zillions of acre feet of water could be recovered, along with
great heaping bunches of electricity. Plus lots of timber. 

The entire prospectus, of course, was an outright lie. The
Grahams are precambrian intrusives with virtually zero
mineral content whatsoever. The site today is a plain old
short mining tunnel. 

BTW, all the locals have their own favorite spelling and
pronounciation of "McEniry". And love to argue about it.
I'll stick with his signature on the above prospectus. This
is also sometimes called the "Triumph Tunnel Site". 

Somewhat further west was the Spenazuma Mine, shortened
from getting "them" to "spend their mazuma". And a 
classic example of blatant salting. Today, this is on a private
ranch on which visitation is strongly discouraged.

What might or might not have been a scam was the Bear Flat
Irrigation District.
 In which artesian water was run over a 
long series of canals and lakes in what today is totally barren
and dry as a bone.

More modern is the saga of the Banana Farm scam. Which older
Thatcher residents do not want to talk about. Also, for some
strange reason, nobody but nobody in the entire Gila Valley
wants to talk about the "Golden Letter" scam whose pyramind
scheme flushed out the entire area during the 1980's.

Managed to field verify that nearly ALL of these "curious
rock alignments"
  do seem to be prehistoric canals!

I'll change the name to the Riggs Complex.

Evidence includes their apparent extreme efficiency of
construction, their slope and linearity, the lack of any
concrete or rebar, the lack of hallmark CCC signatures,
a five inch mesquite growing mid channel, consistency
of cross section, and uniform caliche/pavement/lichens.

Beyond that, things get highly speculative. Frye Creek
suggests a credible water source, delivered via a branch
off the Robinson Canal. Fields associated with the canals
are rather vague and possibly demolished by heavy
area flooding.
Huge boulders are involved.

It is not at all clear whether all the canals were used at once
or in some sort of time sequence.
One alignment is wide
enough to be a pioneer wagon road, but seems to lack any
evidence of grading or mechanical assistance. Let
alone any pioneer purpose or goal.

Things are rather vague compared to the other hanging canals.

Even stranger and yet unchecked is this area. While obviously
CCC, did they "steal the plans" from an underlying
prhistoric origin? Why? Curioruser and curiourser .

Our Automatic Background Mottler / Vignetter / Filler-inner
demands that these rules are followed if it is to work properly...

There MUST be ZERO unwanted red=255 pixels!

While these can be eliminated programatically with several
of our routines, they can inadvertently be replaced by such
actions as resizing, gamma, contrast, brightness, sharpening,
color balance, or similar commands..

A useful workaround is to back off the color balance in
Imageview32 or whatever by two or three small clicks.

Do this imediately before creating any "real" red=255
pixels in your outlining process..

All wanted red=255 pixels MUST be continuous!

Even a one pixel "hole" will cause the background to "blast
through" the portions of the image to be retained. It is also
important that red=255 places boundaries on any image
portion that goes offscreen.

But until several obscure bugs can be further checked, it is
best to avoid any red=255 pixels within two pixels of any edge.

Internal fills MUST be solid.

The external mottlers work up to just beyond first red or white
pixel groups, starting from east, west, south, and north. But the
internal fills work on a pixel by pixel replacement basis.

It is also super important to have new and different output
filenames for both the mottling and tilt correction routines.

Examples of the superb results of our mottler appear here.

One thing the new Acme Mapper Gila Valley image resolution
has made apparent: There are an unbelievable number of CCC
projects remaining in the area.
Way beyond hundreds, and
possibly in the thousands.

The overwhelming majority of which seemed to me to be totally
and utterly useless makework boondoggles. Your economic
stimulus spending in action.

Here's a dozen water spreaders as examples.

In general, a CCC project will be much larger, more linear,
and higher than a prehistoric one.
It will also be much more
distinct on an aerial photo. And often exhibits anglo
"stone masonry" skills. With railroad tracks or cables or
fencing sometimes thrown in for good measure.

Caliche, desert pavement, and  lichen demarkments tend to be
obvious and wildly out of line. Some rocks will often show signs
of wheelbarrow or truck use through their local mismatch.

Prehistoric projects will almost always be much more energy
efficient in their construction
, and will almost always have an
obvious and an overwhelmly defining purpose. Aprons are more
common on prehistoric check dams.

Prehistoric projects are also much more likely to have very old
cacti or mesquite trees mid channel and are often "run over"
by dams, roads, and old fences without any accomodation
whatsoever. There is also very strong "stole the plans" evidence
where anglo pioneers repurposed small portions of spectacular
prehistoric originals.

Much more here.

The improved imagery in Acme Mapper has just found yet
another hanging canal

We might call it the Riggs Canal. Small, very steep and rather
poor workmanship. Extremely rocky terrain with huge
boulders. Area to the north is even less hospitable near the
east-west fence.

Potential length is two to three miles.

There is no obvious reason to believe this is not prehistoric,
despite the extensive CCC work in the area. I feel this
particular canal may have been incomplete or a failure.

Potential source would be an off feeder from Frey Creek
via the Robinson Canal. Its potential use is not at all
obvious and does not look ag in the least .

Also curious is that the hiking trail to the main Robinson
Canal should have crossed this canal at some point. But
such a crossing has not yet been noted.

Verifying the exact route of our Allen prehistoric hanging
below the misnamed Hawk Hollow Tank may prove
tricky because of the extensive CCC rework in the immediate
area. There are at least three dozen CCC water spreaders in the
target area!

This is over and above its fairly difficult access. Nearby portions
of the canal are interesting because they "hang" their way
"up" out of washes and include remarkably long and deep cuts.

As always, the world class prehistoric engineering boggles the mind.

The reason to hang the canals in the first place is to make their
slope independent of terrain
. For spectacular energy savings.

At present, there are several gaps in the six mile long Allen Canal
route. A short unverified stretch near the Spring Creek takein point
that is not expected to have much in the way of surprises. The
abovementioned CCC spreader area, and the crucial region between
the mesa and the dam.

Plus, of course, determining the ultimate destination and use of the
system. To date, it simply vanishes into the "Black Hole of Central"
after a well defined run.

One of the apparent requirements for our Magic Sinewaves
is a precision time delay that has low overhead, lots of states,
and is totally jitter free.

This requirement is non trivial and pretty much excludes many
traditional timers on many older microprocessor chips. It
also pretty much demands programming in raw machine

Especially if pinch points are to be avoided in the code for
higher values of "n" that combine the need for both very
low and very high delay values.

Here is a PIC table lookup timer that has a one instruction
cycle resolution combined with interrupt free zero jitter and
a mere SIX cycles of overhead.

CALL as subroutine with delay value in W
and PCLATH preset to page three…

02FE SUBWF PCL,1 ; move pc to needed delay
02FF NOP ; padding - never accessed
0300 NOP ; burn one cycle if used
. . . . . . . . . . . . . . . .
03FD NOP ; burn one cycle if used
03FE NOP ; burn one cycle if used
03FF RETLW 0x00 ; return to calling routine

Unfortunately, this was only an eight bit solution to a twelve bit
or higher problem. In the past, factoring had to be used to
sop up most of the delay with a crude timer and the rest of it
with the precision code above.

The problems should be resolvable by going to a new generation
of samely priced 16- or 32-bit microprocessors. These also have
ridiculously more flash memory. Which should allow internalizing
frequency setting. Or using seemingly outrageous blocks of table

The traditional ways of dealing with banners all seem to have
problems. .BMP files have the best appearance ( especially with
antialiased small text ) but are outrageously large. While .GIF files
have licensing, dithering, and obsolescence issues. And JPEG files
tend to trash small lettering and splotch everything up on small images.

It turns out there is a fairly new kid on the block called a .PNG file.
It lossless and without degradation can dramatically reduce the
size of a .BMP file.

A .PNG summary is found here and the full spec here.

At first try, the .PNG file may not reduce a .BMP all that much.
Going from, say, a 50K image of 280x65 down to 25K. But there
are tricks you can pull that can actually make a .PNG file smaller
than JPEG or GIF.
While retaining full .BMP appearance!

Reducing the number of colors to sixteen or fewer can have the
most dramatic effect. This may mean that if you are using
antialiased lettering from our Bitmap Typewriter or whatever
that you may want to adjust the antialias shading to a limited number
of values, perhaps six or eight maximum.

Mottled backgrounds should also be replaced with a solid color.
The .PNG code algorithms are related to both Huffman and
Run Length encoding, so the fewer the colors and the longer
the color runs across the banner, the better.

.PNG files also support several transparency modes. The simplest
of which lets you round the edges of a banner or create odd shapes.

Going back to some ancient history that I think it is now ok to
talk about, side looking radar required that a swept waveform
be collapsed through a linear delay versus frequency device

to get from a target phase history to a target display.

Before things like the Fast Fourier Transform and sanely priced
digital techniques, the only practical method was to use ray traced

The process is utterly simple. Take an image plane and shine
coherent light through it a distance x from, say, a convex lens.
Place a second frosted image plane another x distance on the
other side of the lens. Presto. The image Fourier Transform
appears on the frosted image plane.

I'm making some progress on Thumb Drive "websites".

Apparently Chrome grabs anything and decides if it
is a website or not by whether it starts with a "http" .
It then remembers the location as a "real" url or
alternately as a PC host based filename.

Any new filenames are then made "virtual" and
"relative" to the initial host name if they do not
start with "http", and as absolute web references
if they do.

An image inside an "include" folder might be accessed

glotz = "includes/barro.jpg"

I'm not totally clear why you do not need or want a
leading slash here, but the above seems to work.

One hassle is that Chrome apparently does not
recognize any <include " "> or <#include " ">
Apparently because it is client based and
does not involve itself with server side includes.

I'm not sure what or whether includes can be included
in Thumb Drive websites. There is some sort of an
document.head.appendChild method, but it looks
both scary and flakey.

Your suggestions on including incudes welcome.

Oops. There's a blowup bug in our Background Mottling

The obvious workaround is to make sure there are no red=255
pixels ( iutentional or otherwise ) on your top image line
. The
odds of this happening can be much higher than you would
expect. Unintended red=255's are eliminated automatically
if you use the nutilt or nored code first.

The code fix could be as simple as changing to a maxnorth 2 sub

The meanings of "normally open" and "normally closed"
are exact opposites, depending on whether you are talking
electrically or pneumatically.

A normally open switch or relay contact has a gap that DOES
conduct electricity or signals or whatever. Until such
time as its position is changed or coil power is applied.

A normally open valve DOES allow a liquid or gas flow
from input to output. Until such time as its position is
changed or coil power is applied.

Valves are often further complicated in that if liquid
stays stuck in a pipe, nothing much happens
. Thus,
three way, four way, and even five way valving is
more the norm. In which you either provide air or
oil or else let it drain off or return somewhere else.

Maricopa Solar just went belly up and shortly will be auctioned

They seem to have been done in by a combination of dropping
pv prices, trying to mix problematic technologies ( Carnot
limited solar thermal with Stirling with Hydrogen ), issues
with reliability and downtime, and plain old bad math.

Ferinstance, their 38 foot diameter ratio telescope style
device label generates 25 kilowatts. Or about the needs
of ONE electric car!
The real output would likely be around
20 kilowatts peak, equal to a hundred kilowatt hours per
day or about $10 in retail electricity per day.

Which would amortize out to something like a total investment plus
land plus labor and maint to just under $30,000 per unit. That, of course,
would be for a totally pointless "paint it green" transfer payment

We'll be further populating our internal banners in the next

"view source" on your browser.

On the server side, all that is involved is a .js include in a
.SHTML file. On the client side you will find a short and
fairly simple JavaScript routine.

Part of the routine is a data array in which three elements of
each banner have their custom info stashed: Where to go to
get the banner art; Where the banner link is to take you, and;
The alternate banner text.

A second portion of the code takes an array that is nothing but
an advancing stack of numbers and shuffles it. Shuffling is done
by repeatedly interchanging any position with itself or one that
is somewhere lower in the deck.

The third part of the routine simply repositions each banner as
needed. Note that all banner slots fill each time and there are
no repeats.

PostScript code for a new Apache 404 log reporter appears

This scans an Apache/Debian style log file and first extracts those
lines with a 404 error report. Lines are then truncated to only
the error and the referrer. Lines are then grouped and counted,
creating a report of worst first.

A key algorithm midstream is to use a sorted array-of-arrays format
of [ [ (firsterr) firsterrcount] [(seconderr) seconderrcount] ... ]

The array is then top to bottom scanned one line at a time. If the
current line has a different error of the next lower line, it goes into
a new array. If the current line has the same error as the next lower
line, its own count is incremented by one and placed in the count
of the next lower line.

Web Log files can be enormously useful, but there are
significant differences between IIS and Apache/Deleban.
Which means a lot of hidden rework on this end.

A log file normally consists of text lines ending in a
line marker or carriage return. Spaces are used
to "tab" between entries, and a hyphen "-" is used
when an item is missing.

The log files are usually issued daily and might be
.gx or otherwise compressed. If so, they must be
uncompressed to plaintext before any use.

There are nine fields to an Apache/Delbian log file...

calling website in nn.nnn.nn.nnn format
dns name lookup (usually omitted -)
dns customer lookup (usually omitted -)
[ date and time ] in brackets
method (usually GET) and file gotten
results of attempt 200=good 404=bad
referral came from ( sometimes - )
browser and system.

DNS lookup takes a lot of computing power and
bandwidth, so it is often omitted. Sometimes you
can do your name lookup using Whois.
dedicated URL's are no longer the norm, so this may
only get you as far as a number block inside an ISP

Referrals can be enormously useful, but there are
recent complications that need dealt with. At one time,
it was a good bet that any "?" in a referral meant
a search and that these were easily readible. But
these days, most searches go through Google and
parsing their very long URL's can be a hassle.

The new banner rotator is now up and greatly improved.

first defines an array full of the banner specific HTML

src='http://banner art' alt='text_message.'</a>";

One of my favorite examples of mathematical subtlety
is the error in the "obvious" card shuffling algorithm.

Why, to shuffle "n" cards, you simply random interchange
each card with itself or another one in the deck. Right?


This stunt will end up "fairly close" for a full deck of 52 cards.
But it introduces severe errors for, say, eight banner rotations.

Here's why: Consider the worst case of a three card deck.
There can be only six possible outcomes. But there are twenty
seven intermediate results. 6 does not divide into 27 very
well, so you will have 3 possible outcomes that happen 4
times each and 3 possible outcomes that happen 5 times each!

The correct ( and actually faster and easier ) algorithm is to
replace any card with a random choice of itself or any other
card that is LOWER in the deck.

Yes, it has been scientifically proven that a five

improve vehicle mileage and reduce pollution.

The key gotcha is that there is no known way to
produce the hydrogen on board that is remotely cost

I am utterly amazed at the depth and breadth of Google's
search abilities. It seems that the overwhelming majority
of industrial part and stock numbers can be readily found.

Especially if they are more than six digits and have letters
and dashes in them. And espeically if given a hint or two
as to what they are and their intended use.

Here's some of the routes I'll use to find the value and
popularity and currentness of an item for eBay resale or
Auction bidding...

I'll first Google the part number to find the number of hits,
the manufacturer, and any company name changes. I'll
then try the manufacturer's web site and see if I can get
current technical data. On oddball older electronics, sometimes
the newsgroup can be of help.

Next comes finding the item value. Should this not be obvious
on their website, my favorite useful places include PLC Center,
OEM's Trade, or McMaster Carr.

Plus the usual suspects of Mouser, DigiKey, Newark, and the
rest of the gang. Or, for the really obsolete stuff, Rochester
or 4 Star Electronics .

An interesting consequence of current product development
is that form no longer follows function.

Not so long ago, if you wanted a telephone, you had to place
a heavy transformer and a klutzy dial in a box too big and too
heavy to pick up.

If you wanted a camera, you had to have space for two cylindrical
rolls, a film plane, and the bottom out of a coke bottle or some
similar pice of glass out front.

Television sets and other display devices had to be heavy and deep
because of how far you could bend electrons in a vacuum.

If you wanted some information, you had to carry it around either as
a flat disk or a long strip of tape or film.

If you wanted some light, you ended up with a high intensity point
source and severe heat management problems.

These days, a telephone can be any shape and size, and routinely
can include a video camera, a pocket watch, a flashlight, a GPS
receiver, and a laser pointer as an absolute minimum.

Display devices can now be arbitrarily flat and thin. Flexible, even.
Cameras can be any shape and size. Even ( a mystery to me )
including SLR lenses that once cured a long gone defect.

Gigabytes ( and soon, terabytes ) of data storage can be any shape
or size and often totally static. With a present size limit of slightly
larger than an USB connector.

And point source LED lighting makes no sense whatsoever, as multiple
sources with managable heat become the norm.

Yorg. The water powered car that refuses to die --> still <--

Crudely engineered and waaay overpriced kits are now
available that let you conclusively prove the bogosity of
the original rotten labwork. No, I won't give you the link.

Nearly the entire circuit can easily be replaced by one USB
friendly fifty cent microprocessor.

A fundamental thermodynamic property called "exergy"
ABSOLUTELY GUARANTEES that electrolysis from
high value electrical sources such as grid, pv, or alternator
flat out ain't gonna happen.

The value of a kilowatt hour of electricity is usually insanely
higher than the value of a kilowatt hour of unstored hydrogen
gas. Thus, the process is pretty much the same as 1:1 exchanging
US dollars for Mexican Pesos.

Believe it or not, overunity hydrogen production from electrolysis
is in fact possible
. Under special lab conditions, the process can
end up as much as one sixth endothermic. (Which, BTW, also
explains why automotive fuel cells also ain't gonna happen.
For no hydrogen fuel cell can be over 83 percent efficient. )

The only little gotcha is that endothermic production can only
occur at exceptional low gas production rates. Guaranteeing that
amortization will nail you to the wall.

We picked up a bunch of genuine Canon Circular Mil
style threaded connectors and will shortly have them
all listed on eBay. For a tiny fraction of their usual
$40 to $80 distributor cost each. All in their original
factory poly packaging and absolutely "as new".

Deciding which connector is which can be confusing.
You can start with this Canon data website.

All of the connectors offered are threaded, rather
than bayonet twist lock. The shell size is the
number of sixteenths of an inch for the threaded
diameter. Thus a size 12 shell would be 3/4 inches.

There are two styles. The "3100" style is intended
for panel mounting but also includes a clamping
strain relief. It can be identified by its rectangular
shape and four mounting holes. The "3106" style
in intended for cable end termination and also
includes a clamping strain releif.

The "P" options provide male pins, while the "S"
options provide female sockets. Note the four
variations: panel male, panel female, cable male,
and cable female.

Most of the connectors use the "standard" insulator
rotation. But any with a "W" through "Z" in the
part number have their orientation rotated through
a specified number of degrees. W will only mate with
W, etc.. This gives up to five options for a given
connector to prevent cross connecting.

Amazingly and incredibly, a new variation on the Fast
Fourier Transform
has just been discovered that can be up
to ten times faster! Per these details.

The trick is to use a precompression that only needs
calculations for the coefficients that actually will end
up significant.

I'm still going to stick with the plain old classic discrete
Fourier Series for our Magic Sinewwave Calculators,
though. Because for this use, it is astonishingly fast,
much more easily understood with lower level math, and
completely eliminates any windowing or envelope hassles.

MOTTBK1.PSL - Automatic Background Mottler. Replaces NESW
backgrounds with random patterns up to first white pixel, optionally
fills all internal white pixels, and optionally does border vignette.

DODBURX1.PSL - Version of Dodge and Burn utilities restricted to
light shading correction. Original full code here.

BMTYPEW2.PSL - Bitmap typewriter provides exceptional small
typography on top of existing bitmap image  artwork. Newly revised
to allow mottled or randomized backgrounds and web friendly colors.

NORED2.PSL - Utility to eliminate any true reds or whites. Needed to
prevent punchthrus if tilt correction size, gamma, or brightness changes.

Found another way of looking at the Architect's Perspective
distortion correction that seems to work and seems to have
a reasonable geometric explanation.

Assume you want a howmuchtilt of 0.5, equal to an extreme
fifty percent correction. Uncorrected, the 0 row position of
a diagonal should stay where it is at 0 and the top row position
of a diagonal should also stay where it is, normalized to 1.0
times the image height.

The 0.33 row position, however, should end up at 0.5 normalize
height. The 0.5 row position should end up at 0.707 normalized
height. The 0.67 row position should end up at 0.866 normalized
height. This is precisely a plain old normalized sinewave!!!!

Per this figure.

I'm not sure exactly why this happens exactly at a fifty percent
correction, but the math sure seems intuitive and accurate.

Lesser howmuchtilt corrections can be made between linear and
sine in a proportional manner.

As mentioned before, we are in the process of dramatically
reducing our older inventory items. Particularly those that are
two or more years behind in being listed on eBay. We are
also flushing several zero interest items.

This also improves our quality control in that only the best
of the best will get newly listed
. Favoring currently popular
"like new"items.

At any rate, many tons of inventory have been turned over to
an associate, and you should be able to pick these up at
outrageously low prices. Items may be viewed and picked up
in the Tucson Area.

You can contact our associate for further details.

A reminder that our background mottler demands a
continuous white border around your subject. Even
missing a single pixel will cause a breakthrough that
will demolish much of your image.

The external and internal algorithms are somewhat
different. First. a mottled background is placed
one row at a time from the west, stopping on the
first white ( or true red=255 ) pixel. The process is
then repeated from the east, the north, and the
south. Then, optionally, any internal white pixels
will get replaced with their mottled background

Note that the external fills stop on the first white
pixel, while the internal ones fill white pixels only.

Thus, if you have an undercut or an intentional
"hole" in your subject, it should be made solid
white or red=255.

Should you intentionally want to "bleed" into a border,
you will still need at least one white pixel at the
extreme edge.

Iffen it ain't broke, don't fix it.

Yesterday's distortion correction via table lookup seems to work
and its latest version can be found here. But somehow, the math
is not what I expected and is by no means intuitive.

If you are simulating a view camera tilt, you would expect the
image rows to move up on the screen. And if you are moving
different vertical positions right or left by different amounts,
you would expect nonlinear distortion on diagonal lines but not
on the horizontal or vertical ones. So far, so good.

But I was sort of expecting math that had an obvious geometric
interpretation, perhaps related to an inverse tangent series.

Instead, our table lookup seems to be based on a function of
the class k(x - x^3) and I seem to be at a loss to explain why.

Per this plot and this sourcecode, red is the table lookup accurate
to the quantization. Blue is a very good cubic spline fit. Green is the
best three point cubic polynominal fit matching amplitude .58 and 1.0
and slope 0 at .58.
And black is the function with the quadratic term

There's no reasonable doubt that the table lookup error based
approach works. Especially for sane amounts of correction. but
how it works remains a mystery to me.

Your analysis and comments welcome.

Each value represents how far up a given scan line should be
moved to correct curvature distortion. The 800 entry table should be
scaled against the actual number of scan lines in the image. The
number read should be scaled against the howmuchtilt compared to
0.5 or 50%, further adjusted if needed, and then converted to an

That integer is then used to move each scan line up from its
present position. A detailed example appears here.

There is a penalty of approximately one third the vertical resolution
at the full 0.5 howmuchtilt. But substantially less for more
realistic amounts of adj
ustment. Nonetheless, the highest
practical resolution should be used for this correction.

Here is a summary background for tomorrow's table

I have long been overly enameled of architect's perspective
in which all expected vertical lines end up truly so. Especially
for our eBay product photos. An older way to do this was
to use the swings and tilts on a view camera.

I've long had some PostScript based swings and tilts code
that worked fairly well for modest correction but tended
to "bend" slanty lines if the correction was too high.

I recently started an obsessive program to see what could
be done in the way of repairs. It did turn out there was
a minor error in the algorithm and that centering the adjustment
on the subject also greatly minimized any observable effects.

But distortion in extreme cases remained. This was caused
by different portions of a slanty line being moved different
distances, causing nonlinear effects somewhat akin to
barrel distortion. Horizontal or vertical lines were not
directly affected.

A good approach to any mystery problem is to "make it
. So, I asked what kind of distortion we could
expect from an extreme 50% correction. By starting
with this image that could represent one quarter of
a building being corrected or an eBay product photo.
As expected, after the correction here, the horizontal
and vertical lines ended up just fine, but the principal
diagonals ended up "really bent".

The needed correction appeared to be moving the scan
lines up in the image
, similar to how the view camera  
did so as tilt was advanced. For an extreme 50%
tilt correction, the middle lines need moved up
one sixth of the total screen height.

No correction is made at the bottom or top, up to
a one sixth vertical rise at the middle. The result
gives us straight diagonals, straight verticals, and
straight horizontals. And presumably is ( at the
very least ), a whole lot better everywhere else.

There is a penalty of one third the vertical resolution
at this extreme case
. But this is much less for normal
corrections. Nonetheless, the distortion correction
should always be done at the highest practical resolution.

Another reason for highest practical resolution is that
nearest neighbor interpolation can be substituted for
more exotic ones which might add an extreme speed

The present code can be found here.

Seems to be the time of year for WAG predictions.
Here's my current assortment...

While pv solar still remains a gasoline destroying
net energy sink that is in no manner renewable
nor sustainable, it is in the process of turning
around and ultimately becoming viable. In
part because of CIGS and the new quantum dot
developments, improvements in high frequency
efficiency, and ( thankfully ) to the elimination of
obscenely counterproductive subsidies.

Goldilocks and other exoplanets are now being reported
at a one per day rate and soon will become common
as dirt. We will be in deep trouble the ( reasonably soon )
day that one of them receives a lucid ten second clip
of Roller Derby as the sum total of our culture. The
alternatives, of course, are Captain Video or Kukla,
Fran, and Ollie

HVAC ( heating, ventillating, air conditioning ) is
obviously due for a major efficiency upgrade.
Brought about by MEMS and nanotechnology.

One obvious product crying to become reasonably
priced: hot tub heat pumps.

Your website is unlikely to just keep growing in
popularity like it did in the past. Brought about by
the "eyeball siphoning" by the social networking sites,
the upsurge in online video, and the norm now being
full HDTV video as a web experience.

Things that no longer make any sense whatsoever are
the US Post Office, "Big 3" network Television, over-
the-air tv transmission, public libraries ( unless totally
and immediately reporposed ), or any tax funded
Public Broadcasting. Also utterly useless is any
tv set that does not include unstricted web access
or does not provide at least full HDTV resolution .

Santa Claus machines are about to drop dramatically
in price and greatly expand in availablity. Brought
about in part by low end open source examples
such as this one or this one.

Word will finally get out over exergy being the reason that
the hydrogen economy flat out ain't gonna happen. In
particular, electrolysis from high value sources such as
grid, pv, or alternator is pretty much the same as 1;1
exchanging US dollars for Mexican Pesos. A kilowatt
hour of most electricity is ridiculously more valuable
than a kilowatt hour of unstored hydrogen gas.

Printed industrial trade journals can be expected to vanish
enritrely. Their useful content has been long since gone
and their economic model has become laughingly pointless.

Drug legalization should soon dramatically turn around as
governments and municipalities will no longer be able
to ignore it as a major income source.

Dot matrix printers can be ridiculously improved by going
to a pair of duplexing full width printheads. The mechanisms
become ridiculously simpler, the paper path totally direct,
and speeds insanely faster. Reliability and the cost learning
curve will be the key issues here.

The latest of light emitting diodes now include warnings
not to look at them
because they are too bright. Efficiencies
are getting totally offscale, with 150 Lumens per watt
production and 250 in the lab.

Finally got some distortion correction in our Architect's Perspective

Starting with the top row, the scale factor needed for the initial

Had a caller ask about finding geranium transistors for
guitar stomp boxes. Naturally, in this day and age, if you
want to add noise, hum, or distortion, you use a decent
DSP algorithm
rather than vacuum tubes, primitive solid
state devices, or other performance limiting and highly
unpredictable components.

But to answer the specific question: One good info source for
older semiconductor secret sources in the
newsgroup. And eBay has bunches of older semis readily
available. Both on our own auction store and elsewhere.

A surprisingly high number of older components still remain available
at major distributors. A very good place to check is OEM's Trade.
A second often useful resource is PLC Center.

Meanwhile, there are firms that specialize in obsolete smis. And, if
all else fails, they will even custom build new ones for you. Two
examples include Rochester Electronics and 4 Star Electronics.

4 Star seems be down to their very last 28,525 NKT275's. Which
remain enormously popular with the stomp box revivers.

The neat thing about germaniums was that they were so leaky that
you didn't really have to bias them.
Provided, of course, that you only
ran them at one temperature.

The math behind the distortion in Architect's Perspective
is a tad obtuse, but easily resolved using a first principle
of "make it worse" and seeing what a simple polynomial tells us.

Consider this extreme case of a fifty percent correction. We apply
the usual "progressively shorten each line" for this intermediate result.

Where we see that our vertical lines are now straight and vertical, and
our horizontal lines remain straight and horizontal. But, sadly, our principle

diagonals are badly distorted and bent.
As will be much of the rest of the

It looks like a repair can be made by raising the intermediate rows. Perhaps by
one sixth in the middle.
Normalize the right diagonal so it goes from 0,0 to 1,1.
Assume this bent curve can at least be approximated by a polynominal of
y = ax^2 + bx + c.
Since y=0 at x=0, c will also be 0 and can be ignored.

y = 1 at x = 1, so we have our first equation of a + b = 1. Assume from measurement
of the figure that y = 1/3 at x = 1/2. Which gives a second equation of a = 2b .
And a tentative solution of a = 2/3 and b = 1/3.

The desired "curve" should be the linear y = x, so our error function will be
x - 2/3*x^2 - 1/3*x    Or 2/3x*(1-x).

Per this plot, the approximation correction appears "close enough" But not
a true correction. Looks like a further small sinusoidal adjustment may help. Or
finding the actual "real" math.

More testing soon.
And code eventually.

Some amazingly clean "nearest neighbor" interpolation code
seems to have evolved from our distortion correction

Our usual array-of-strings will contain a pixel line in the
typical Bitmap   .....bgrbgrbgr...  sequence. A desired left
shift or right shift could end us anywhere in the sequence.

Which clearly is ungood, because blue has to stay blue
and the starting point of each pixel triad must be an
integer as well.

This repositioning does it all...

a continuously rotating potentiometer without stops that

What could get cute in a hurry is if you stacked two of

It can be real easy to lose track of the fact that storage
units should be emptied at the same rate they are filled

Otherwise you end up needing more and more space with
worse and worse junk hiding the stuff you really need.

Otherwise known as "shit floats to the top".

There is an optimal rate at which stuff should end up on
eBay. For us, this rate is often a twenty eight day cashout
and a fifteen month hang time.

Thus, ideally, stuff should be listed within a very few days
of acquisition
and never should need stored more than two
years. Most espeically if not listed.

Sooooo, we are long overdue in making a dramatic cutback in
our stored inventory items
. These will be flushed to a
third party and should become available at ridiculously
bargain prices. By the truckload.

A reader asked about .PDF files for some handheld genealogy
apps. I was not sure if what level of response was needed.

For many uses, Adobe Acrobat .PDF is an ideal way of presenting
technical information. Especially when the exact layout format is
important and when high quality integrated graphics is a must.

There are three flavors of .PDF. The Acrobat reader is free but largely
prevents you from creating yoxur own material. Commercial or educational
versions of Acrobat
can accept a wide variety of input content for conversion.

And alternate versions such as GhostScript give you open source options.

Acrobat .PDF is based on the PostScript language, of which you'll find lots more
here. But because of the extreme power of PostScript, Adobe has restricted its
ability to do most of its more useful tasks involving unlimited disk access. The
SX workaround is to run "acrodist-F" from the SX command line for full use.

But Adobe has qotten quite secretive about this access option recently, especially
on other or newer computer systems.

I remain an overly enameled fan of PostScript and .PDF. But with newer
small screen or low resolution devices, there are emerging alternatives that
reasonably should be explored.

In particular, check out the Android 3 version of Java. With some help from
Linux and C+. Microchip has a new Android Development Kit as well.

Something that could be between an interesting development
and a major pv panel solar breakthrough can be found here.

At present, the efficiency of a conventional solar cell is abysmal.
You would be extremely fortunate to get nine percent efficiency at
the terminals of your synchronous inverter.

There is a fundamental technical reason for the bad efficiency.

Any wavelength of light has an energy level associated with it.
For e equals h nu and all that.

If you have a conventional single workfunction photoconverter,
any light whose wavelength is too long can not knock any electrons
loose, and is lost as heat.

If the light's wavelength ( and thus its energy ) is just right, you can
knock one electron loose with quite high efficiency.

If the light's wavelength is too high, all of the "spare change" energy
is also lost as heat. Thus, only one magic wavelength of light can
be efficiently converted. Too high or too low, and you burn up the

Previous proposed workarounds have included cells with several
workfunctions, quantum dots, or light frequency downconverters
involving phosphors and similar stunts. None have proven economically
or engineeringly viable to date.

The proposed new method apparently can knock two or more electrons
loose when fed light of a high enough frequency.
And does initially
seem eminently workable.

The Science paper can be found here.

Some pv panel economics can be found here, an industry trade journal
here, a pv solar tutorial here, and general energy stuff here.
