Automated NERF Vulcan EBF-25 turret

I rigged an Arduino up to a servo to control trigger motion, connected a USB webcam to feed to motion, linux motion detection software, and wrote a short python script to interface with the Arduino and have mplayer play back a random Portal turret sound.

Now, when the door opens, the laptop plays one of the Portal sound files ("I see you", "target acquired!" et cetera) and pulls the trigger for a second. Once it finishes detecting motion, one of the other Portal files is played ("Nap time", "Target lost", et cetera).

The gun itself is a NERF Vulcan / Havok Fire EBF-25, with three ammo belts chained together to give a 74 round capacity, and an upgraded battery (3S Lipo) which about doubles the rate of fire.

See http://www.youtube.com/watch?v=-FBXKrU1Jec for turret-side video footage and http://www.flickr.com/photos/randomskk/sets/72157624178093055/ for photos!

Thats fuckin sick. Dude u got mad computer skills. Now if you modded your vulcan to shoot bbs, i would pay u like $300 dollars to do that. Then anyone who came in my yard would be toast
