DIY High Voltage AC Power Supply

[@Qwertyoneify]

I built one myself a while ago, with a capacitor from a microwave. Mine would throw out 30kv or so. Very dangerous, and amazing. Good video!

[@ludicscience]

+Nathan Boody Thanks!

[@peterc07]

i'd rather just use the microwave transformer then and add 2 capacitors in series to make it resonance . much better cuz high current and voltage . maybe even add a ballast

how many volts needed in which it couldn't harm a person that holds the wire

[@leblancmeneses3650]

How about using a 120 volt to 12 volt transformer with just an on off switch? That would give me a 60 cycle pulse out of the ignition coil but is there something I am not considering I dont want to give my dogs a permanent smile. Should I use some kind of resistor to limit the current?

[@tvtrompasdiegoyanto9550]

For the voltage triplicate what value do you use on the capacitor and diode?

[@EstjwabCom]

this week I'll start doing one maybe with dual ignition coil, hope 1.5uf (630v) with 240vac mains will work. can't find 1uf or less around me. next week I'll get an oven. my goal comparing emp effect and distance from magnetron and high voltage.

It's not isolated from mains so it would probably be dangerous.

[@kickcast7995]

Hi Ludic Science, I am building a rat zapper that will utilizing your schematic and adding a PIR sensor switch at the 220V source plus an MCB as fuse. One question, If NEGATIVE coil terminal and the HIGH VOLTAGE terminal successfully zap a rat and the rat will stay there, do you thing the MCB fuse will trip down (due to shortage in the circuit)? I want the circuit to be automatically ON when PIR sensor catch a move, so it can zap multiple time per setup. Currently I am using mosquito zapper part to electrify the zapper, but I need to use 220v to 3.7V DC stepdown and currently it works great with small mouse. I want to build a little bigger zapper that will kill bigger rodent for continuous use. The circuit is use in our own property with enough security inside a barn.

[@danburch9989]

Without going into physics, voltage and frequency aren't really dependent upon each other. Voltage is the amount of energy (in very basic terms); frequency is how often that energy is expended or used. You can have 100,000 volts pulsed 1x per year (frequency) or 100,000 volts at 100,000x per second.
