EMPs (Electromagnetic pulse) are quite popular in the world of science fiction. Wouldn't it be cool to have one of your own? That's what I thought when I started building it.
I wanted to make an EMP which will be portable and which can be hidden under full sleeves( That's naughty!). If you have the right parts, you can build it in no time. If you don't, you're in trouble.
WARNING: Not for children under 15 yrs of age :D
Well seriously, If you get a shock it'll shake your spine. These capacitors are really powerful. So please be cautious while handling the circuit.
I SHOULD NOT BE HELD RESPONSIBLE FOR WHATEVER THINGS YOU DESTROY
An old camera circuit, doesn't matter whether its disposable or not is absolutely necessary. If you don't have one, its not that tough to make one, but it'll take lots of time. An alternative way is to use the circuit of a zapper or a separately sold camera flash.
I used the circuit of a 15-yr old camera. Just had to take out the circuit out of it. The circuit runs on a 3V battery system.
The reason I used a normal camera circuit in place of disposable ones is that the capacitor in a normal camera is much more powerful than the disposable ones. If you use the circuit of a separate flash, its even much more powerful than the normal cameras.
Please be careful while taking out the circuit. The capacitor might still have stored charges.
