Not so deadly BUT painful Taser!!!

Well this is not for the faint hearted. If u wanna make ur own taser (220V or 1KV) this is how u do it(WARNING : Dont try this on any1,before u try it 3times on yourself)...
Taser guns come in various types, but for starters we will keep it simple..Here is what u need for making the 220V Taser-
1) 9V or 12V battery
2) 909 Transformer or 12012 transformer if using the 12V battery
3) 2 BC547 Trasnsistors (Any NPN transistor will do)
4) 2 1/4W 10k carbon resistors
5) 4 1/4W diodes for making Bridge rectifier
6) 100uF 450V rating Capacitor (it is imp u use 450V rating, it just costs 30INR)
7) PCB to put the stuff togethr

Principle and Working:
1)First u make an astable multivibrator using the two transistors and resistors. Then u take this pulsed DC and feed it to the transformer's usual secondary (the side which gives +9,0,-9V when u put 220V in the primary).
2)By doing this u will get 220V pulsed DC in the transformer's ususal Primary...
3)Now put a bridge rectifier in front of the end from where u are getting 220V pulsed DC, to get (220*1.414)V DC...cool....but remember this DC voltage is very high Impedance and thus not at all harmful to any one...
4) Now u must charge a capacitor(450V rating) with this High DC voltage.
5) As soon as the capcitor will be charged ( around 15-20s) u will have a painful voltage strike ready.
6) Diconnect the capacitor from the charging circuit and direct it to two conducting metallic plates or bars.

Make some one touch the ends and see them get a 220V shock...its not deadly but it sure is painful!
Cheers!
