Hi Kone,

thanks, I have made a short video. You are saying this could be real voltage so I am posting the link again:

It seems possible that the coil is indeed acting like a capacitor too: Before I had a cap on the output the o/p voltage was lower, I then charged a cap. The interesting thing, after removing that cap again the voltage remained higher than before.

Put meter away from sparks and coil, that's making all electronics crazy behaviour in field...
Also if you put bridge made from fast switching diodes then charge capacitor from BEMF, expect high voltages there.

Could not get the high voltage effect again today. Max DC voltage w/o cap I can get is 82V on the meter. I can flat out the voltage on DC side with caps. But it still doesn't seem to be enough to fill a 1000µF cap fast enough. Tried to connect another coil as a generator like the one I have, output was just 10V.

Hi Chalamadad

I bet the reed switch is already worn out from those HV spikes and short-created oscillations -  a bit of carbon has already covered the contact points and it doesnt work like it did anymore.....shorting coils at peaks does the same thing to coils as a Tesla HV spark-gap does - they both will collapse the coil, and when switch or gap "opens" the coil goes into highe frequency oscillations...
anyways try my idea of shorting the "other' peak that you see on scope then maybe you can fill up 1000uf cap quick..

other idea is to chop up your input-pulse whatever it is, into cluster of five or so on-off pulses that overall cover the same pulse width as the existing one fairly large pulse and short each of those pulses...

other idea is to short once very quick then short the oscillation-peaks created from the the intial short...

or combine the two ideas, chop the intial pulse up into 5 or so, and then each pulse has its oscillations created from short have those oscillations themselves shorted at peaks... this is Ismael's MEG more or less as far as I understand it...

Hey Kone,

I can short both peaks with the reed, that's when I get about 80V. Although it does sound promising this still ain't enough. At least I don't know how to deal with it yet. I have the same DC converter that Romero had. When I hook that up to the output I am having just 2-3 Volts again. After all those small bipolar caps are filling to 250V almost instantly. But 4.7 or 22 µF won't do it.

Remember I am playing just with a generator coil. No input pulse. That is yet to come when I'm gonna try your coil-shorting circuit.
