  • 12V-180kV: A Battery Powered Marx Generator (and introduction to electronics)

    Well, maybe with a really BIG Marx Generator, but I have tried to use two different Marx Generators for Kirlian experiments (one of them discharging around 100KVDC), but did not notice an effects which suggested that they were working. Kirlian photography machines all seem to utilize high voltages AC and not DC which seems to suggest that AC is what actually works. Too bad I can't ever find a non-rectified flyback. Guess an ignition coil is still the best way to go DIY and at least they are pretty cheap on Amazon.

    Did this work for you? I have not found that coils work very well with this kind of pulsed high voltage, but I am not very experienced with building coil guns so maybe I did something wrong. Never did try adding a cap in parallel with the coil so maybe that would have made a difference?Anyway, I sure would like to know if you had any successes with this.

    So I have built a mere 7-stage Marx Generator and it produces somewhere near 100KVDC at the business end. When I fire this thing off, just by itself, in my office, my computer about 10 feet away acts REAL funny! My monitors turn on and off, windows get moved around. Some windows get closed while new ones get opened and, sometimes, I completely lose one of my monitors until I perform a reboot and entirely reconfigure my video settings to, once again, recognize my multi-monitor adapter. I built a 9-stage handheld variant and it will also cause these effects using 2 AA batteries as the supply source so I know this is EMF and not shorting high frequency, high-voltage to outlet ground.Point is, I'm not sure this setup requires a coil, at all, to be effective for your stated goal, though ...see more »So I have built a mere 7-stage Marx Generator and it produces somewhere near 100KVDC at the business end.

    If you scavenge one of those bug zapper rackets and use that circuit as your supply source, you can make a Marx Generator which runs off of 2 AA batteries which would make it a lot more portable. I have, personally, built a 9-stage "hand-held" Marx Generator which uses one of those circuits and it works very well, considering the power-limitations of those bug-zapper circuits.
