Bill Hunter posts on the Vans, HomebuiltAircraft and vaious lists using the handles
Vans101, Homebuilt101 or similar. He has a velocity.

Thanks anyway for the tip but the co-author is Bill Batten, not Bill Hunter.
I sent the article to Bob. He can post it if he desires.

Greetings all,=C2-Anybody know if an Arduino will create interference wit
h the aircraft radios, including GPS.=C2-Same question with regulators. W
ill a switching regulator create noise that we can't use or is it best to u
se a linear regulator with it's attendant heat problems. 12V to 5 V.=C2-T
his is a little above my pay grade.=C2-Hope everybody is staying well now
=C2-Thanks.=C2-Rich

unlikely but easy to test in VMC
flight. The only predictive activity
you can pursue is to take it to an
EMC lab and run the full suite of
radiated compatibility tests. You
probably wont find any violations . . .
and even if there are some, the
probability of posing a risk is
low. The last EMC lab time I rented
was about 20 years ago and it was
over $750/hr!

I take it you're not talking about an
alternator regulator. What energy class
are we talking about? Mounted on an
ECB to stroke the Arduino parts?
I wouldn't worry about it.

Thanks Bob,
I am considering using RC servos to regulate heating airflow from a fan heat
exchanger (liquid cooled) to enable me to electrically control 3 tubes
=94front seat, rear seats and defrost. The servos need pulse modulated... a g
ood application for the Arduino. The servos and Arduino need power at aroun
d 5V thus the necessity for regulator.
Maybe these kind of things have stretched my build time to 16 years and stil
l counting=F0=9F=A4-

I run several 5 volt arduinos for data collection, displays, and signal
processing in plastic boxes and haven't detected any issues whether they
are powered or not. No effect on a couple of gps receivers or VHF comm.
I do not have an ILS or VOR receiver.

Ken,
Very encouraging.
What are you using to reduce to 5V?
Thanks
