I built my second Bedini/Ihmotep Fan using more powerful fan and have setup an SCR, 16V Zener Diode and 450V, 270uF(M) cap using the schematic from here http://www.energyscienceforum.com/sh...ull=1#post6937
Once I got it running I noticed that every time the cap dumps (roughly 4 times a second) it seems to slow down the Fan a little and emits a type of soft knocking sound. I have tried some different Zener Diodes and CAPS and all of them do the same thing (albeit at different intervals). Is this the excepted behaviour?
Without this CAP setup, it spins without this "knock".
