Introduction: 400V Stun Baton!
I was so annoyed at my seatmate that I vowed to pump 400 volts, 0.04 milliamps, 16 watts of calculated power into them in DC form. It all started when they started this quite insulting song that's been going around our part of the isle recently, so I reconsidered modifying that electric mosquito killer in order to make them think otherwise. This is also going to be used against my bus-mates (which are all too annoying..) and in self-defense. I opened it up so that I could see the circuit, and it was a relatively simple one. I am yet to reverse-engineer the circuit, but I could tell you that there was a 400V Mylar capacitor and a small transformer (inductor) in there. It's just a simple mod that involves opening up the unit, cutting wires and reattaching, then putting it back. The electric mosquito killer is in the shape of a tennis racket. It had some odd design in the middle. The business end consisted of 3 grids charged in the following order: negative, positive, negative. While I was still working with it, I got electrocuted (fingers, off course) and it felt like I was being thrown forward. I also considered turning it into AC (it could be a pure or modified sine wave, square wave also works); my friend kept saying, "remove the damn diode!" but I never did until I drew up the circuit so that I could know which diode to remove. I also considered adding 10kOhms worth of resistance in there in order to decrease the amperage further to increase safety. As long as it incapacitates someone for a while, then it's good. If YOU'RE (I meant my seatmate or bus-mate) READING THIS, <insert evil tone> watch out....
EDIT: I remeasured, and somehow, the voltage went up to 565 and the amperage went into the kill zone of 2.3 milliamperes. Now I have to recalculate how much resistance I need for this to not kill anyone. I have recently electrocuted myself with it, and it hurt much much more than I remember.
We have a be nice policy.
