This DIY Automated Sentry Gun Looks Terrifyingly Easy To Built

I know we're only halfway through the week, but I've already got the freakishly scary weekend project I want to take on. Some folks have put together instructions to build a completely automatic, autonomous sentry gun.

All the instructions, from how to build the firing mechanism to the open-source control software, are available on the site below and while the video clip leaves a bit to be desired for lack of an actual gun (water or otherwise), I still think this is one kickass project. I can't wait to build one and duck while it shoots paintballs at anything that moves. [Sentry Gun via Boing Boing]
