Remember this guy? Well, he's back with a new "how-to" video that explains how to make a coil gun.

Is he intentionally being an idiot?
Wow.. Everyone is talking about how silly this guy is & I am left thinking how fast I could get a projectile going with an 18650 li-ion or 2 that I have hanging around..

Aluminum may not be the best material. Just a hunch.More coils = more field
More current = more field
tighter coil = more field
fairly straight forward on how to get more of a pull/push. Use aluminum to get it moving faster (less weight), not sure your battery will do much though.

Would have lived longer if he had a simple flyback dampening circuit. A single 1N4007 diode would make the coil shut down faster, less drag on the projectile and no more spikes to damage the MOSFET/FET/etc. But then the guy can't give it ALL away, and this way he gets another fun meltdown.
Wondering what country he is saying he's from where he says he can only get a butter knife.
