Aside from the electromagnetics (in a linear electric motor config) and bolt-action which supports a six-round magazine clip, this gun makes use of a multimeter, a few custom switches to turn the weapon on and off, some PVC piping, a scope, and presumably, a battery pack. My favorite part are the fold-down wood legs for those moments when hitting a can with extreme accuracy is imperative.

But the use of electronics and the clever use of wood through out the design give it a DIY allure that I just can't resist. But check out TechEBlog's vid for your self. It's pretty cool. [TechEBlog]

Don't count on holding an invasion of them, though. The coil gun—which uses electromagnetic coils configured as a synchronous linear electric motor, accelerating fire metal pieces as it goes through it—needs eight seconds to have enough electric charge. And that's while plugged to the wall. With batteries, it's 90 seconds.

That said, it's quite impressive, knowing that it only took its creator, Daniel Eindhoven, 40 hours to make it. I want. [The Contaminated]
