Joe,
If you want, I'll send you my prototype DeSlumpifier for testing, since it is just
sitting on my desk gathering cat hair.
Contact me at Perihelion at charter dot net.

Joe, it would be an excellent experiment to put
Eric's hardware to the test in real hardware.
In the mean time, send me the booster you
bought and let me do some tests on it as well.
There should be NO significant AC component on
its output.

Which booster did you order?

Bob,
I communicated privately with Eric and he is sending me his DeSlumpifier for testing.
Thanks Eric.
OK Bob, I will send you the voltage booster. I have your address: PO Box 130.

Above is a link to the voltage booster that I ordered. It only cost $3.25. They
say you get what you pay for. It cost a little more than some others, but
still cheap. The copper coils looked impressive compared to some other units
without them. I can not find any more like mine for sale on eBay. People must
not be satisfied with them or else they would still be for sale. I bench tested
it before giving the seller positive feedback. But I neglected to check
the AC component of the output until it failed to power the Dynon D-180. Do you
still want me to send the unit to you Bob, or should we just consider it a
poor design and toss it?

Joe, all these DC to DC converters have ripple on their outputs, because th
ey have to convert the input DC to AC, then rectify it and filter it on the
way out.- On this particular model, you will see 180 KHz ripple plus har
monics.- Unfortunately, the ripple amplitude is not specified.- On top
of that, it is not protected for input reverse polarity.- I believe you m
entioned earlier that you tried switching input leads to see if the AC comp
onent went away.=0A=0A=0AI personally would not buy this product without th
e output ripple spec defined, especially for aviation applications.- I'm
also leery of Made in China products, although I know some are excellent.
