The Simplest Circuit

Ever wondered build a high voltage generator powered only by a battery of 1.5 Volts? Well, this circuit described herein, taken from the website Indestructible is able to do this. It generates a voltage of about 450 volts, enough to give a very nasty shock. Before thinking of doing this project, read our disclaimer.

The most critical component in this circuit is the transformer, it is used in flashes of cameras. This transformer is a ferrite with five pins. The ferrite transformer must have five-pin, if the processor has 4 or 6 pins, it will not work for this project. But you make an adjustment if you have experience in electronics.
