Voltage Multiplier Waveform
« on: January 08, 2016, 18:06:04 pm »
good to see you are on the mots.... =) good luck
post some more about it...

One thing I'm doing with my MOT is building a voltage multiplier.  This is a simple diode/capacitor circuit which will increase the transformer's output voltage.  Here's an example of the circuit:

Here's a typical waveform:

Stan Meyer mentions DC ripple voltage so I'm going to see if this waveform can charge a cell.  If it does, it may turn out the be the cheapest approach.  With a multiplier, the ripple at a single capacitor can be extracted.  Additional circuit elements can then be included.

I tried that to for a while and just recently took it off my dual MOTs.  It worked well for making high voltage.  Yet the VM took all the sharpness out of the signal and made things noticeable quieter.  It looks the same on the scope but is obviously buffering the sharp signals.  I usually can make the wha wha sound at certain frequencies and the see the voltmeter and amp meter arm flop back and forth, but not any time with the VM attached, it's all smooth through the spectrum from 200hz to 200khz.

I make more gas I think without it because things are thrashing around more in the cells and the transformers make a sound related to the frequency I'm using.  Plus you have to wait for it all to slowly discharge before you grab anything...  ouch

Thanks for your feedback on this, kb.  It's encouraging that you did make some gas with it.  (Unless you're referring to "without the volt meter".)  I'm hoping mine will too, although I'll be testing a circuit variation.  I won't be taking the output from the high point electrode to ground.  Rather, I'm interested in the voltage on a single cap.  I'll be using a technique which produces pure static.
