CAUTION: Before going to explain about this circuit, we are going to strictly suggest that DO NOT TRY TO IMPLEMENT IT PRACTICALLY AS IT PRODUCES VERY HIGH VOLTAGE.
DO IT ONLY UNDER A PROFESSIONAL'S GUIDANCE!
A stun gun is usually a device used to produce a very high voltage, low current signal and is used mostly as a weapon to stun or send shock waves to the target with the intention to weaken or paralyze the target.
However moving towards to design the circuit, it should be kept in mind that in some countries, stun gun is banned so this project is only for educational purpose.
Because, this is actually a lethal weapon which can render a person mentally and physically paralyzed. It is usually powered by a 12 Volt battery or by a 12Volt DC adapter.
The stun gun circuit uses a 555 Timer to produce a current fluctuating signal and a voltage multiplier using a transformer and a multiple stage (8) arrangement of voltage doublers using capacitors and diodes.
You can use a Mosfet in place of BD679. For eg: IRF220
As soon as the switch is pressed, the operation of 555 Timer starts. A pulsating electric signal of low current is produced because of supply, which is stepped up using a step up transformer, to a voltage of around 1000V. The signal from the Timer is fed through the transistor switch.
All this results in the output of around a thousand volt which is enough to stun the target for some minutes.
