[Dragonfly DIY] Today's irritating lesson

You can NOT just blow off the filter caps on an AMS1117 LDO regulator. It will go into oscillation or some damn thing and you'll get squat on the output. That small input (and larger output) capacitor is actually necessary. Guess I'd better get a stock built up.

I've been trying to get into the modern era, getting away from the old 7805 and big through hole components, ordering up reels of passives and strips of regulators, but this is the first time I've used one of these. Spent an hour and tried 3 regulators, thought maybe the ebay vendor had slipped me some garbage.
