Subject: | Why? [Please Read] |
Dear Listers,
Each year I like to explain why I have a Fund Raiser and also take the opportunity
to express why I think the List Services here provide a superior experience
over the commercial equivalents.
I use the List Fund Raiser each year to offset the costs involved with running
a high performance email list site such as this one. With the annual support
from the List members through the PBS-like Fund Raiser, I have found I can run
the entire site without having to inflect any of the members with those annoying
banner ads flashing up all the time trying to sell little-blue-pills or other
garbage nobody wants or needs. From the comments I've received over the years
regarding the Lists, the great majority of the members really appreciate
the non-commercialism of my List systems and don't mind my 'go-team-go' banter
once a year during November to encourage members to support the Lists.
I believe that the Lists services that I provide here offer many benefits over
the commercial equivalents in a number of ways. The first feature I believe to
be significant is that you cannot receive a computer v*rus from any of these
Lists directly. Each incoming message is filtered and dangerous attachments
stripped off prior to posting. I also provide a Photo and File Share feature
that allows members to share files and bitmaps with other members and everyone
can be assured that these files will be prescanned for any sort of v*rus before
they are posted. Safe and simple.
Another very important feature of this system in my opinion is the extensive List
Archives that are available for download, browsing, and searching. The Archives
go all the way back to the very beginning of each List and with the very
fast Search Engine, the huge size of some of the Archives is a non-issue in quickly
finding the data you're looking for.
And added just this year is the new Email List Forum that allows members who prefer
the Web BBS-style of List interaction. The beauty of the new List Forums
is that they contain the exact same content that is distributed via email. Messages
posted via email are cross-posted to the respective Forum and vice versa.
The Forums also allow for another convenient method of sharing pictures and
other files. Additionally added this year is the new List Wiki that allows
members to build their own "Online List Encyclopedia" of sorts, documenting various
aspects of their project for all to share.
I've been running email Lists and services under the matronics.com domain since
about 1989 starting with RV-List and 30 guys I knew and who where also building
RVs. It has grown into nearly 70 different aviation-related Email Lists and
an associated web site that receives over 23,000,000 hits each year!! Additionally,
the List Email system forwarded well over 87,000 postings last year,
accounting for an unbelievable 39,000,000 (yes, that's 39 MILLION) email messages
delivered to Matronics List subscribers! I think there's a lot of value in
supporting a service that has gone the long haul and is still providing and
improving a high quality service all _without any advertising budget_!
I have to admit running these Lists is a labor of love and I hope it shows in the
quality of the experience that you receive when you get a List Email Message,
Search the Archives, use the List Browser, or surf the Forums and Wiki sites.
The Lists will be here for a long time to come. If you just want to lurk
a while for free, that's great and I encourage you to do so. If you use, appreciate,
and receive value from these Lists, then please support them during the
Annual List Fund Raiser!

My friends,
I understand the frustration with folks who do not
understand, embrace or even fight for the principals
of liberty as enjoyed and protected by an honorable society.
It's a difficult concept to grasp by individuals
who are raised and live in an atmosphere of perpetual
victimhood.
There are plenty of blogsites where folks are encouraged
to offer their views of world conditions. Let's not let
this List loose its grip on the mission. I'll encourage
all participants to choose their words so that they
illuminate points of fact and logic in the assembly of
simple-ideas into useful systems.
The single biggest threat to the usefulness of our endeavor
is to pitch mud balls and cabbages at anyone for any reason.
It adds nothing to the mission and discourages folks
from attending to the discussions when they loose
interest or believe they're being attacked. The whole
notion that hatred is justified by anything other than
grossly dishonorable behavior is illogical but
this is not the venue for the discussion. Let's
strive to offer words that expand our knowledge and
understanding of physics and the art of crafting the
best airplanes. But without demeaning others with
pejoratives and imagined or real shortcomings in
personality.

Not sure I've properly installed the Ground Power Jack per the diagram
from Bob. I'm wondering if I have the circuit breaker switch properly
connected--which terminal goes to the ground ("Line" or "Load") & which
goes to the contactor?
When I connect power to the plug the test light comes on, regardless of
which position the circuit breaker switch is in. Is this what's
supposed to happen? I am thinking that I should be able to test the
ground pwr contactor to see if it's closed by testing the voltage across
the terminals but I don't get the voltage I expect (~ 12 v?). I'm using
a Schumacher Model WM-1562A "Fully Automatic Battery Charger/Maintainer"
(1.5 amp slow charge)when I test the system.

There are several ground power wiring options in the
literature I've published. Since you speak of a light
then I presume you're referring to the drawing shown
in . . .
http://aeroelectric.com/articles/grndpwr.pdf
The symptoms you describe suggest that the light
fixture is wired wrong. There are three terminals
on the back that must be wired as depicted or
you'll get unpredictable behavior which includes
the symptoms you've described.
I don't think the WM1562 charger is appropriate to
simulate a ground power source. This charger is of
limited output current . . . about 1 amp as I recall
and the ground power contactor needs about 0.7 of
the total. It MIGHT work but without trying it
or doing more detailed analysis of the charger's
expected behavior, I cannot predict.
When you connect a ground power source (try a battery
with a 10A fuse in the line), the indicator lamp should
be dark as long as the breaker-switch is open. Pressing
the fixture should produce a light showing that ground
power is applied and that the lamp is good. Closing
the breaker should also cause the contactor to close.
This will happen with a audible "thunk". The light
will come on also showing that ground power is now
applied to ship's wiring.
A reversed ground power source will cause the switch
breaker to open immediately after you try to close it.
Likewise, if you've installed the over voltage protection
option, applying 24v to a 12v airplane will also cause the
switch=breaker to open.

Subject: | Volume & Transmit Issues |
Bob et al,
I just energized my simple VFR panel for the first time this weekend. I'm
happy 'cuz there is only one issue: Garmin GNC 250 XL seems to function
EXCEPT volume is intermittent & it will not transmit voice. A handheld
plugged into the antenna both receives & transmits fine. Also, when the PTT
button is pushed the 'TX' symbol comes on in the display & the click can be
heard in the headphones, yet the voice will not transmit.
Any suggestions on where I can begin troubleshooting this issue?
Thanks,
Grant

Good suggestion Bob. I agree. While it's not the
best we know how to do, the consequences of having
the 'foreign' coax in place are probably not all
that bad.
Getting a good sweep of antenna SWR as-installed over
the full frequency range of interest would be a good thing
to do. If it stays below 3:1, it's probably not worth
the $time$ to rip out and/or work around the compromised
system.

And just so people on the outside don't point fingers and assume that

that the $12,000 was done away with, that a department could write a

politicians get to look like they're doing something about corrupt
purchasing procedures AND someone gets a job.

The 'economic impact' is that I would have to go out and find metric AN
hardware for my project, redrill all the holes, and physically swap all
the hardware out. At that point, I have to again find the metric stuff
whenever I do maintenance. I, like every other builder I know, would
prefer to just say, "You first." If I were running a company that built
water heaters, every one of them would go out the door with fitting that
matched what is commonly available at Lowe's and Home Depot; otherwise,
I'd quickly be out of business. May not be a national impact, but my
family wouldn't appreciate how much of a patriot I was trying to be. If
I were running a company that made lawn mowers, every bolt hole would be
tapped to match the hardware that was on the shelves of Ace Hardware.
Same logic. You call it micro-economics. I call it feeding my family.
Stop calling people clueless. It is not about metric vs the English
system (and it is a system, no matter how convoluted it is). The debate
is a about a new, more efficient infrastructure that was designed vs an
older, ingrained one that just grew out of nothing. Why wasn't the
legacy system well thought out and logical like the metric system?
Because we didn't even know we needed it until we already had it, and at
that point it becomes painful to switch. Europeans have had the dubious
'benefit' of having their industrial infrastructure devasted twice in
the past century, thanks to a couple world wars. At the point where
there is no Lowe's, Home Depot or Ace Hardware, because they ALL have to
be rebuilt...might as well go with the efficient system. We also see
Europe and the ex-Soviet block nations adopting advanced cellular
infrastructures much quicker than the US. But people forget that the
new 3G (third generation) systems there don't have to compete for
customers with the legacy 2G systems. It's much easier to build an
advanced system if you have a slightly less advanced system to build off
of. It's also much easier to implement it if you don't have the older
system to compete with.

Yup, unfortunately a group of folk in every society are burdened
with the notion that critical review means to "expose"
every real or imagined "bad" point that one may think of.
If one wishes to be an effective reviewer, it's insufficient
to simply toss in mud-balls . . .
I have a proposal floating around my workplace now to set
up a REAL IR&D facility with a modest budget but no windows
to stand in line at. ALL purchases will be made on one
credit card. At the end of the month, we get a single piece
of paper that lists where every dime was spent. No
secrets, no intent to defraud, but no impediments to
progress. When someone needs a tool or material item, he
or she does all their own procurement and turns in the
receipts and packing lists at the end of the month.
The successful venture depends on smart, honorable folks.
I prefer to assume they're honorable and to provide
the environment in which they can get smart. It's up
to each individual to prove themselves worthy of the
responsibility and trust. ISO (or government) approved
policies and procedures are incapable of offering a cost
effective filter for incompetence or dishonesty. It
will be my responsibility to see that funds are properly
spent.

This metric "world vs the U.S." debate is entertaining. But I want to make
sure I've got it straight: Americans are stupid for messing up one of the
many space probes we sent to Mars because two different U.S. research and
space sub-agencies used different measuring systems (of the 15-20 or so
there are to choose from), causing that probe to crash. This in contrast to
the genius of others who've settled on a single system for all such
measurements in the many probes they've sent to Mars?

Lee,
> This metric "world vs the U.S." debate is entertaining.
I would like to point out that my original question was "When or why did
the reversion from Celsius to Fahrenheit occur in aviation ?". The
debate was all between North American citizens.
There is no such thing as a "world vs the US" debate in Europe. We just
use units, period. We are trained to change units if need be.
Just remembering to convert into inches and pounds when talking to US
citizens. We consider it a matter of politeness.

It came as a shock to the aerospace and scientific community to discover
that the top brass and engineers in this project did not even give any
consideration to the problem of multiple unit systems.
Units and dimensional analysis have a paramount importance in science
and engineering.
That is...in the rest of the world ...;-)

Gilles, just joking ;-)

I have several lists that I look at - the AeroElectric being my
primary. I contributed to that list but not others.
I am not sure how the support is supposed to work - support your work
or individual lists.
It is OK if the intention is to support every list individually -
please let me know.
Thanks for your very useful work

This gentleman has demonstrated that the most efficient
pathway to success is an exploitation of time, talent
and resources of "smart people" who are not encumbered
by what I call, "*impediments to progress*" and he calls,

very capable associates and managers but my professional
wet-dream would be to have enjoyed an association with
the likes of *Dr. Virgil Elings*. http://tinyurl.com/nudtw

My professional dream would have been to work with *Kelly Johnson*
in his *Skunk Works*. I was born a few years too late for that to happen,
but I had an almost equally satisfying stint working with the
*Defense Advanced Research Projects Agency* (DARPA)!
http://www.*DARPA*.mil/body/overtheyears.html<http://www.DARPA.mil/body/overtheyears.html>
They had very few "*impediments to progress*" - and that's only one
of the many things that attracted me to the place.
*DARPA* is an unusually small Government agency that funds research.
They were formed back in 1958 (same year as NASA) and their research led to
the ARPAnet, Stealth technology, tele-surgery, body armor, and many other
things.
Some items are now classified, some aren't. In accordance with their
mission,
DARPA has had some costly dead ends, as well as some tremendous successes.
They do all this with a staff of government folks that has "swelled" to 240
people
since they were formed in 1958. One of my favorite DARPA examples is a
useful device
that went from "concept" to "deployed" in under a month during the first
Iraq war.
(Can't provide more details now, try again in about 40 years. ;-)
Some people argue that DARPA has reached the tipping point at 240 people,
and the "good years" are all behind them. I hope (& suspect) that isn't
true!
My background includes many years working for DARPA; first as a military
officer, then as a contractor. So when I was digging wire out of
dusty boxes
in Oakland and benefiting from the dietrus of the NASA and Loral contract -
it wasn't that I didn't understand what or why the Loral folks had to do
this.
Instead, it reminded me of my years at DARPA and deepened my appreciation
of the time I DIDN'T spend "*standing in line at windows*" and taking
unmarked ESD bags back to my desk to dig for two tiny washers
that were quite literally "lost in the paperwork".
So while I was both amused & appalled, I wasn't surprised at what NASA had
required or what Loral had to do to comply with their contract.
NASA has a very different mission than DARPA, and the NASA staff of more
than
19,000 has a longer & much more complicated chain of accountability
than DARPA's staff of 240.
This isn't meant as NASA bashing. Instead, consider it as encouragement and
a challenge for the competent folks to seek out rewarding opportunities
that still exist at places like: DARPA, Scaled Composites, and other
places.
These opportunities aren't gone with Kelly Johnson, they're just hard to
find.
A good friend of mine helped me build my *Lancair ES* and now he works at
*Scaled Composites*. (I know they have some DARPA contracts.) He can't
tell me what he's working on, but he can't hide the smile on his face
either!
The satisfying & rewarding jobs are out there - you just have to find them!

Assume you used a headset with the panel mount, but you didn't say whether
you used your headset with the handheld, but if not, the issue could be
there.
I recently had an experience where I did not have good communications with a
new headset I was trying out - turn out that the microphone under the foam
pad was facing away from my face rather than toward it. Flipped it over and
it worked fine.

Subject: | Wig-Wag Makes Strange Buzz |
I installed my taxi and landing lights in my Mustang II kitplane,
using the WigWag system described by Bob Nuckols in his published
article http://www.aeroelectric.com/articles/WigWag/WigWag.pdf
The WigWag flasher came from B&C Specialty. I am using two
independent 2-10 (three-way) switches with independent power sources for
each light. The system is wired per the instructions. Everything works
as it should, with one small exception, noted as item No. 6, below.
1. Both switches down - everything is off
2. Both switches up - both taxi and landing lights are on
3. Either switch up - the light for that switch is on
4. Both switches in the middle - power goes through the WigWag
flasher and the lights alternate on and off in about one second
intervals.
5. Taxi light switch (only) in the middle - light is on but no
flash.
6. Landing light switch (only) in the middle - FLASHER GOES
CRAZY!
In the last described position (no. 6.), the landing light
flickers and you can hear an audible buzz coming from the flasher. The
flasher seems to be vibrating rapidly (many times or dozens of times per
second) between on and off.
I think the vibrating mode occurs when the power runs through the
middle connector of the flasher, because when I change connections from
the flasher to the Landing and Taxi Light switches, then the buzzing
starts only when the other light switch is moved to the middle.
I do not understand why one light merely turns on when a single
switch is moved to the middle (flasher) position but when the other
switch is moved (alone) to the middle position, the flasher goes nuts.
Does anyone have an explanation for this strange behavior?
Perhaps the answer lies in the way that the flasher works, but since I
do not know or understand the mechanism of the flasher, I cannot figure
it out. I guess the simple answer is, "Don't put a single switch in the
middle (flasher position)." But I would still like to know why this is
happening and whether there is any way to prevent it. I do not want to
inadvertently damage the flasher by accidentally triggering this
vibration mode and leaving it there.

Subject: | Some tips on using self-sticking Velcro |
In my various capacities as supplier to the OBAM aircraft
industry and skunk-werkser on the TC side of the house, I've
found many uses for the self-mounting, pre-stickied Velcro
products sold by Hobby Lobby, WalMart and others. On of my
favorites is a "Heavy Duty Adhesive, Industrial Strength"
product I've been buying at WalMart in the crafts department.
A 15 foot by 2" wide roll is about $8 as I recall. I've
never encountered a situation where holding power of the
Velcro was lacking but getting the adhesive to stick can
be iffy on some surfaces.
I've found that wiping the surface down with acetone (pure
acetone available in cosmetics as nail polish remover. 8 oz
for about $1.50). Then use your heat gun to warm the adhesive
to as hot as you can stand while holding the Velcro in your
fingers. Stroke it for a minute or so under the heat gun.
Press into place firmly and know that the bond is somewhat
time sensitive. It may take 24 hours to reach full bond
strength. Putting this stuff down with the technique described
has produced some amazing attachments . . . some have required
the heat gun to re-soften the adhesive so I could pull the
stuff up. I've used this technique to install remote mounted
instrumentation packages in the hell-hole on airplanes and
in the nose compartment with results that amazed folks I
was working with. One skeptical technician didn't think Velcro
would hold this 5 pound data acquisition signal conditioner
in place.
http://www.aeroelectric.com/Pictures/Data_Acquisition/Weeder_Module_DAS_1.jpg
I invited him to remove it after I'd installed it. He had
to go get a pry bar to open the Velcro interface and we
needed a heat gun to get the adhesive to let loose of the
airplane when we were done. He's convinced.

Since under the new Military Commissions Act any response from a
non-citizen could get them treated here like Sadaam used to treat his
dissidents in Iraq, perhaps you will permit me, a born once (& again) US
citizen, to respond.
It's really interesting how different conclusions can be, depending on
your perspective when viewing a problem. How thrilled do you think
Americans would be if, say, the Germans decided to secure our border
with Mexico for us & moved a hundred thousand or so German troops into
our border states? We might think we are doing the world a favor by
protecting it with troops stationed in dozens of countries, but it
doesn't mean that the 'protected' citizens of those countries
necessarily feel the same way.
I'd suggest that you educate yourself with a little history. Start with
learning how the three groups in Iraq got artificially spliced into one
country. Then look at who gave the Evil Sadaam chemical weapons to start
with, when they were propping him up against the Iranians. Then back up
& look at who put the Shah of Iran (just in case you're totally ignorant
of history: he was a bad guy easily on par with Sadaam) in power in the
early 1950's. Ask yourself if that action might have something to do
with the Iranian people hating us enough to attack our Embassy & take
American hostages. Next, look up who was the leader of the 'insurgency'
(currently known everywhere else as terrorism) against the Soviets in
Afghanistan, his nationality (it ain't Afghan), & who gave him his
weapons & taught him all his terrorist techniques. Now, look up who is
*actually* responsible for 911. Has his name shown up before in this
exercise? Same guy, maybe? What was his nationality? He wasn't from
Iraq, was he? Now look up which Royal Family has been proven to be
funneling money to this the guy who is *actually* responsible for 911.
(You remember the one; the guy that Jr. said he didn't think about much,
any more.) Were they from the same country as our Afghan/Soviet/American
terrorist? You will probably have to move completely outside US news
sources to find the next item. What reason did the terrorist himself
give for planning & executing 911? Hint: It wasn't Bill Clinton singing
Kumbaiya. Don'tcha think it would be good to at least understand your
enemy? Lots of very smart military people do. Unfortunately, not many
chickenhawk neocons felt that way when they got us into the current mess.
Let's move to recent history. Have you noticed how many 'retired' CIA
operatives have written books detailing how they repeatedly told the
Neocons *before the invasion* that there was virtually no evidence of
WMD or chem/bio in Iraq? That there was virtually no evidence of any
contact at all between the hedonist Sadaam & the fundamentalist Muslim
terrorist that wouldn't even be able to tolerate being in the same
country with someone like Sadaam? (Watching something other than the
Fascist News Network will probably be required for this exercise.)
Remember, the CIA is like the Mafia on steroids: you never really leave.
Don'tcha think it's a pretty safe bet that what all these 'retired'
agents are writing are probably pretty close to the CIA's attitude about
this stuff? Have you noticed how many recently retired American Generals
have gone on record criticizing our Administration's actions in invading
another country based on lies? Do you really think that all those guys
are bleeding heart liberals?
For extra credit, go to the CIA's web site, look up & list the natural
resources of Vietnam.
I could go on (remember the 'missile gap', from the '60's?), but I hope
that by now you're able to detect a bit of a pattern.
Before we deal with some foreigner's plan for the terrorists, let's
deal with yours. Do you live far enough south to be familiar with fire
ants? Ever tried to intimidate a mound of 'em by reaching into the mound
with your hand & crushing a few to death? Did the rest cut & run or
become pacifists & submit because you were stronger? To paraphrase our
illustrious president on lessons learned in Vietnam, if you continue
with your technique, do you believe you will win over the fire ants
unless you quit? Do you honestly believe that your technique is
weakening the fire ants?
When you've completed your assignments, get back to me & we'll talk. :-)

Subject: | Re: Wig-Wag Makes Strange Buzz |
Bob;
Note 1 on the drawings you've linked to, states "The SSF-1 flasher will
not operate unless both outputs are loaded with a lamp. Hence the
requirement to transfer both lamps to the flasher for wig-wag priority
operation" By placing either 1 or the other switches but not both in
the centre position you are violating this condition, hence the flasher
does not operate correctly just as the note explains. (steady in one
case, berserk in the other)

There is a lot of check list etc. entries to be made and I wonder if there

I am not very computer literate and I'm guessing that what I think I want
