Re: Coiling again
Glad to hear you are back in business making sparks and counteracting the
alleged ozone depletion.
Just wondering if you have ever tried the simpler variation of your
interesting Marx gap idea. That is, simply charge your 0.05 uF tank cap on
one RSG presentation, and discharge it into the primary on the next separate
presentation. Charge and discharge are isolated, as you described for your
Marx gap. This would be one bang. Repeat the above over and over with the
same polarity of charge (not switching polarity every other bang as in your
I suppose success of this depends on just how completely the tank cap
discharges toward zero voltage across it after each bang.
Any comments on actual or simulated results would be appreciated.
