To make an extremly cheap taser all you need to do is take apart a disposable camera and keep the green card. then put a wire on the little metal part that sticks out next to the capacitor (the black thing), and put another wire somewere else (just about anywere will do as long as it touches metal). also the two wires that connect capacitor to the rest of the camera are quite good. To charge the taser just press the button that charges the fla#*@! is a good idea to put tape over the rest of the taser so you don’t shock yourself. This taser won’t be anywere near as good as a professional one but it works.
Enjoy and don't fry yourself.
