Cockroft-Walton multiplier Vs. Apple 2

Running on 13 V DC.

Something interesting occurs when an apple is under arcs carrying a big amperage, after some hours, the exposed zone turns soft and fragile, like it had started to rot. It seems the arcs damage the apple at a cellular level.

Technical data:

The circuit revolves around a 555 timer IC, it drives a MOSFET that sends high current pulses through the primary of a flyback transformer, which steps the voltage up to around 1000 volts, the 5 stages with 3kV, 10nF caps do the rest.

EDIT: It broke, again, it's not the first time this happens, I believe the 10nF caps hold too much charge, and the diodes seem to pay the price. Maybe I'll replace them with 1nF caps when I have the time to do so. You probably should take this as an advice if you plan to build one.

You can find the original circuit here, I've just made some mods to make it a bit more powerful.

I also made a video showing the interior of it:
