A local man was arrested today after going on a shooting spree with what appeared to be a homemade gauss rifle. Eyewitness reports state that the individual was screaming repeatedly, "Die Serco scum!! Die!!". He was apprehended when another local man, also with a homemade gauss, shot the offender with a battlecry of, "For the lady Serco!!". Experts are bewildered as to the nature of this crime.

I always suspected that those Itani were less stable than they're trying to appear.

I actually bought one of those kits two years back and got it working. It's fantastic, and very good at embedding a steel ball an inch into the front of a dorm fridge.

I want to build an electric one some day. I mean, to make a super simple one, it can't be too hard. Just hook up a capacitor to a coil, add a barrel and a magnetic ball and you've got a coil gun. Well, I suppose to make it shoot hard, you'd need a lot more equipment and stuff. But yea.

Is this the one we had a thread about a while ago? I think it is.
