You're thinking of a taser. A coil gun basically makes a really powerful magnetic force to pull a projectile towards it, and then shuts it off, letting the projectile fly. I'm using the camera's capacitor to provide this force. It could also be used to make a taser, but as far as I know, that's very illegal in Canada, and probably in the States too.

just seen vids of coild guns on youtube :O they are awsome!
are u sure that the camera circuit works? i've tryed making an EMP with one... copper burnt... it was too thin, then i tryed with thicker copper and nothing happened... anyways good luck with that, Post some pics when ur done!
nite
Joules is watt-seconds, it doesn't care how you use it.
You are off by a decimal, 120µf = .00012 = 12*10^-5.
The voltage is not constant, it decreases exponentially, that's why the wattage formula fails.
This is the wrong approach - your peak current will be much higher, because it will discharge in milliseconds or less. It will be limited and controlled by the inductance of the coil.
When that capacitor is fully charged it will hold 6 Joules of energy. If you can convert ALL that energy into bullet energy then a 10gram bullet would travel at 35m/S or 124kM/h. In reality you will be lucky to convert half the energy and so the good news is that you won't kill yourself. At least not with the projectile - the high voltage is another thing.
Yeah, 6.125J with those numbers. I see someone else has kicked this idea around a few times.
Even at 35m/s he couldn't kill himself. Bullet velocities are ten TIMES that, and kinetic energy goes up with the square of the velocity, so he has a way to go before he shoots himself in the foot and notices.
