Want to build a stun gun? You would be surprised how simple the electronic circuit is. The basic concept is to take a small voltage source and convert this into a much higher voltage. This is done by pulsing a high gain transformer and storing the high voltage in a capacitor. Click on the schematic below for a detailed look at a nice simple design from Electronics Lab.
How Stuff Works has a nice article that explains why stun guns work so well.
Here are some other stun gun designs that are quite interesting. Remember that stun guns are not legal everywhere… Site 1 Site 2 Site 3 Site 4
I own a website that sells very affordable stun guns. It seems like alot of work to build one but good luck if you try. Check out my website if your curious about exactly how they work, stun gun laws and all pricing information.
a stungun is not a tazer, a tazer ‘shoots’, and with a stungun you must touch a ‘enemy’ with it.
the ‘bullet’ of a tazer is connected with something like a iron thread, so you can shoot the bullet out of your tazer while connected with with it.
