/diy/ - Do It Yourself

>charge to a few thousand volts several times per second
For my purposes I need something in the hundreds of thousands of volts, it needs to jump an air gap of around 4.5 inches. The idea being that I make the gap five inches, so if something over half an inch tall, like a mouse enters, it'll automatically discharge. If a rat enters, it'll do the same. I just wanna see them pop on a slo-motion camera.
>not enough joules to do much
I was thinking something more like pic related, but the higher the voltage I can find, the smaller the capacitor.
Five or so capacitors at the size in pic related would be good, but if I can only get them in 3kv then I'd need at least a hundred.
Thus, I'd instead use more capacitors like in >>1381522, in an array of, say, 6 in series, to get the voltage, but then run them 10-20x wide, to get the current/capacity.

Those numbers are sounding much better than what I was looking for, but I didn't think anything homemade would have even a fraction the capacity of anything commercial.
