Another variation of this by using the premise circuit board holder plus the flexi pipes and alligator clips some hookup wire you can really upgrade it nicely.
Nice instructions and final "products". I have one question regarding the full wave multiplier bridge, for our household grid power, it does not seem to make sense to use it because we don't actually have V+, V-, and GND per se. Even when you showed three prong outlet, the voltage on LINE (V+) is relative to NEUTRAL (V-) which is basically the same as V+ to GND due to NEUTRAL and GND bias voltage pretty small. Can you comment?
