Wow, not only is the technical design on this portable coilgun impressive, but the whole thing looks completely badass. Check it out:

After 2 long years of on-and-off work my coilgun project is finally completed. For anyone who doesn’t know what a coilgun is, it’s a gun that fires a projectile with magnetic force instead of gunpowder. The projectile from this gun won’t kill a person, but the electrical energy stored in the capacitors is 78 times the lethal amount for human beings so this is no toy.
