It’s only deadly to paper, but hey. We here at CrunchGear love our coil guns. Tesla coil guns, Wiimote coil guns, robot coil guns, we’ll take ’em all. What can I say, it’s just good fun for the whole family! This one is for baby.
The little light-switch enclosure contains a camera flash battery, some circuit hackery, and the few parts necessary to accelerate a BB to paper-penetrating speed. Want to make your own? Assuming you know how to make a basic coil gun, here are parts used. Go forth and coil.
