Just a micro controller a mosfet and a high voltage module these often get labeled as "stun gun modules' but I assure you the voltages they claim are never correct but still be safe if you replicate this project. The parts I used are down below i'll consider uploading a 3d model if you guys want it but it is kinda useless unless you pick up the same metal containers at the dollar store. I used a 10k pull down resistor I had a 1k resistor as well but detached it and moved the connection I wanna use that one for a peizo buzzer and the 1k resistor was pointless to drive the gate of the mosfet the digispark pins don't output much....
