If you have an interest in CAD, please see http://www.tenlinks.com/CAD/products/free/cad.htm. This is a repository of all things in free cad, and add-ons too.
Despite many forays into other CAD products, I use DesignCad (not free but cheap).
Almost all CAD software does similar things, but if you call tech support
for DesignCad...YOU ALMOST ALWAYS GET THROUGH! This says a lot about the company,
but it says more about the program because they only have a few people in
tech support. Users just don't have many issues.
Later,

Bob,
Since I was the catalyst for this latest round of skirmishes on the
avionics bus, I want you to know how much I appreciate your advocacy
for the OBAM community. The energy and commitment you apply to
improving the state of the art in aviation electronics is awesome and
we all owe you a big debt of gratitude.

Bob,
Is there any way to start with both taxi and landing lights on a 2-10
switch and add the Galls flasher on a separate switch, without adding a
lot more complexity ? I looked at your diagrams but couldn't figure
out if it would be possible.

Joel- I'm using a 3PDT relay with three separate SPST switches that provides the
capability or either or both lights on, and either or both lights flashing.
(Galls FS020 flasher) Looks like you could do the same with the 2-10, one other
SP switch and the relay. Not sure if this is what you are looking for, but it's
fairly simple and straightforward (has to be for me to understand it anyway!)
If interested I could send you a dwg.
Here's the relay: ( $14.56)
http://www.mouser.com/ and search for: 528-3898-12
Catalog page is: http://www.mouser.com//catalog//614/757.pdf
It has .25" faston terminals and a mounting bracket built in to the housing, so
no socket is required.

Mark,
Yes I would be interested in the drawing. What I'm trying to
accomplish is a setup that for me would be intuitive, with the 2-10
switch giving me OFF, TAXI, AND TAXI PLUS LANDING LIGHT. Then I would
like to turn the flasher on or off with a separate SP switch. If your
configuration can accomplish that, then that's what I'm looking for. I
can certainly identify with your comment about simple and
straightforward. Thanks for the info.

So I have a Falcon T & B. This probably means I will have radio noise. How
do I fix this when the time comes? It would be much eaisier to "install"
the fix now while the panel is out for the last time.

For a wirebook, the fuseblock symbol is simply the bus bar with
fuses as opposed to breakers. You can configure your bus with either
form of circuit protection as needed . . . All of the z-drawings
are available from the website in .dwg format and most have
the busses set up to depict fuseblocks.
. . . or am I misunderstanding your query?

Here ya go- one's a .jpg and the other is a .tif (!) Suffice it to say
that Windows-X-FREAKIN'-P and I are NOT getting along-
grrrrrrrrrrrrrrrrrrrrrrr!!!!!!
..........but Explorer will open them both and they look fairly legible
on this end- any questions, let me know! By the way, they were done in
AutoCad R14, so if you have a CAD package, they would work much better &
you can edit to your hearts' content- If you want the .dwg files, let
me know- I did my entire "wirebook" this way- these are only 2 pages out
of WAY too many!!! 8-)
Note that the Landing light circuit is referenced on the right side of
the Taxi/flasher drawing- running both lights from the 2-10 would work
fine if you used the center postion for "both". The slick thing about
this way of doing it is if the relay fails, you still have both lights
and if either light fails, (or switch) you still have the other light
and possibly the flasher, and neither light is dependant on it. I
originally came up with this because I had the taxi light and flasher on
the main bus and the landing light on the e-bus so I'd have a light even
if the master contactor took a crap, or the main bus just failed for
some reason. After much consideration and several chidings from Bob N.,
I opted to keep the total possible e-bus loads to as small as practical
for a number of reasons. Therefore, they are both on the main, just
completely independant of each other except they are wired through the
relay.
Hope this helps.......

FWIW this gauge seems to be a frequent noise source, but not always. I
fly two airplanes with these instruments and have had -no- radio noise.
One is a Cessna 140 with a TKM/Michels comm radio and the other is our
AirCam with a UPSAT GX-60 mounted directly below the Chinese turn
coordinator.
You can see the AirCam Panel at:
http://homepage.mac.com/flyeyes/PhotoAlbum6.html
There are no filters on either installation and both are noise-free.
IIRC Electric Bob suggests trying it first before applying patches--it
may not be broke...

Bob, I looked for this Halogen headlight with the # H4352 at auto parts
stores, but they all show this light to be SINGLE filament hi beam primarily
for Camaros. Small in size at only 2" x 5 1/4" and priced at $29.95 each. So
to get 2 hi beam for landing and 2 low beam for taxi, the price for 4
headlights is $120. Low beam is part # H4351.
I did see a dual filament headlight but it was almost twice as large and with
different connectors. Any further suggestions??

Yeah, I have all that. I was just looking for the fuseblocks themselves.
No big deal, if they don't already exist.

For a wirebook, the fuseblock symbol is simply the bus bar with
fuses as opposed to breakers. You can configure your bus with either
form of circuit protection as needed . . . All of the z-drawings
are available from the website in .dwg format and most have
the busses set up to depict fuseblocks.
. . . or am I misunderstanding your query?

| Subject: | My camera on Ebay . . . |
--> AeroElectric-List message posted by: "Robert L. Nuckolls, III" <bob.nuckolls@cox.net>
I'm planning to do LOT more media presentations and publishing
best done with high quality digital photography. After 45+
years I'm getting clean out of the chemical photo business.
Thought I would miss it when I upgraded to a new Canon EOS
a couple of years ago and sold all my darkroom equipment.
I ran a few rolls of film that the local one-hour place
processed to negatives for me for $3.00 a roll. Used a scanner
to digitize the negatives. Really good results but pretty
clumsy and slow turnaround. Found that 90% of my photo needs
were covered with the Mavica . . . and if I move up a couple
more model steps in the Mavica series, the digital route
will cover 100% of my needs.
Soooo . . . if anyone is interested in a nearly new 35mm
camera, they're welcome to take a peek at:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2927709307
I'm planning on ordering a new Mavica CD1000 next week.
Bob . . .

2D mechanical drawings? I think I did them a few years back
but don't recall using them. I'll dig around in the archives
and see what I can find. I know I have an isometric view of
a 20 slot fuseblock.

Hmmm . . . pulled the 4352 out of my junkbox and sho' 'nuf, it's
a single filament lamp. Sorry 'bout that. I'm unaware of any other
automotive parts in that envelope. If you want to use this
package, you'll probably have to settle for single filament lamps
on each side . . .
Given that they ARE halogen bulbs, the life should be quite long
compared to the so-called aircraft landing lights.
