Are PIDG terminals all the same? I'm wondering if I can resupply locally at

PIDG is a specific type of AMP brand connectors. There are lots of
terminals
(even other AMP brand types) that look the same, but may have different
materials and/or construction. The most important difference is whether
or
not the wire gripping barrel is brazed closed. My local sources tend to
be
unknown brands, so I just order actual PIDG terminals from SteinAir.

"PIDG" is a trade name (Pre Insulated Diamond Grip) of Tyco-Amp
for their particular series of top-notch terminals. An exemplar
part is described at:
http://catalog.tycoelectronics.com/TE/bin/TE.Connect?C=1&M=BYPN&PID=42563&PN=53408-1&I=13
and has features described in . . .
http://www.aeroelectric.com/articles/terminal.pdf#search=%22pidg%22
There are a number of manufacturers who supply similar terminals to
Mil-T-7928/4.
Generally speaking, ANY terminals you find that offer the metal
liner under the plastic insulator will fall in this class of
terminal and are the recommended technology for aircraft.

I agree but I would change the word "stupid" to "ignorant". I don't
believe there are hundreds of millions of stupid people around the world
voting against their own interests, they are simply ignorant of what's
happening around them.

I bought an AeroElectric multi light dimmer from a builder who never used it in
his aircraft.
The dimmer will work great for the few lights, radio, and transponder I am installing
in my RV-9.
One question though, I have an electroluminescent strip above my switch and fuse
panel. Can this be controlled through 'lectric Bob's dimmer?

Oh, how right-on-the-money. But it is even easier than that. Many
transponders will now display the pressure altitude from the encoder.
All you need to do is to dial up 29.92 "Hg or 1013.2 mB in the
Kollsman window and see if the display on the transponder is within
specified limits (150') of the display on the altimeter. You can do
this once on every flight and assure yourself that your encoder and
altimeter are telling you the same thing. If they differ by more than
150' then you know you need to check things out.
I have been away from email for most of the week (flying from FL to
CA via TX and ID) collecting various family members and delivering
them to the necessary places in the country on my way back from the
Caribbean in my Aztruck (Piper PA-27 Aztec to the uninitiated). I am
looking forward to wading back into the fray.

That I don't know.
One of the things I have learned is that military aircraft put the
PTT button on the throttle, not the stick. I have decided I *really*
like that location. The CJ6A has two buttons, one for PTT, and one
for ICS. I just have to move my thumb on the throttle to decide which
to use. You might want to do something similar and use a button to
key your ICS.

Do you care? When are you going to fly your airplane with the comm
and xpdr turned off? For those few times when you are in the airplane
with the master on and the comm and xpdr off will you really care if
the backlight is turned on?
Remember, simplicity is a virtue.

You have probably wired the diode wrong. The main bus attaches to the
'~' input (either one or both) and the e-bus connects to the '+' lead
of the bridge. If you are using a regular diode (or preferably a
schottky power diode) you wire it like this:
main-bus ----->|---- e-bus

If one wishes to draw a parallel, consider the production and racing
automotive communities. The new and innovative stuff comes from the
racing community. That then trickles down into the production
community. The unfortunate problem we face is that the FAA acts as a
serious impediment to the flow of new ideas from the experimental to
the production communities.

| Subject: | Re: 24V LED bulbs |
--> AeroElectric-List message posted by: Brian Lloyd <brian-yak@lloyd.com>
Remember, the forward voltage drop on most red LEDs is about 1.5V.
The forward voltage drop for white LEDs is about 3.0V. You can put
these LEDs in series such that the combined forward voltage drop is
less than the minimum bus voltage and then add a series resistor to
control current.
For instance, if you are using a group of red LEDs that need a 20 mA
current and you want to power it from your 14V bus, you can do the
following. Since you have a minimum bus voltage of 11V, you have to
have a string of LEDs that needs less than 11V. That means you can
put 6 red LEDs in series (6 x 1.5 = 9V) and then put a series
resistor that will limit the current to 20 mA for the max voltage.
The max voltage on your bus is probably 15V. That means that you need
a resistor that will pass 20mA for a drop of 6V (15V-9V). That means
a 4V/.020A = 300 ohm resistor.
If you want to do this with white LEDs use 3V per LED instead of 1.5V
per LED.
If you want to do this for a 28V electrical system then you have a
minimum voltage of 22V and a max voltage of probably 30V. You want a
string of LEDs to be less than 22V forward drop so I would pick
probably something like 14 red LEDs with a forward drop of 14 x 1.5
or 21V. Now I would need a series resistor to limit the current to
20mA for a drop of 30V-21V or 9V. That would be 9V/.020A = 450 ohms.
If you are doing this for a single LED just change the voltage drop
value.

Something less than infinite ohms, probably something like a couple
hundred ohms, but make sure that the ohmmeter lead that is positive
goes to the center pin. Most inexpensive ohmmeters have the *black*
lead be positive. Check it with another meter to be sure.

Yes. You have RF feedback into your headset. Things to try:
1. Try a different headset.
2. Wrap the mic lead to the radio around a ferrite core. Several
turns should do. Do this at the headset end and also at the radio end.
3. Move the antenna to a different place on the airframe more removed
from the headsets.
