I got an Arduino Uno for Christmas last year, and of course the first thing I think of is laser pointer turret. I played with this for months while I learned the basics of Arduino programming. It was knocked apart when hail totaled my Trailblazer.

To simplify rebuilding the turret, I bought a pan/tilt kit from trossen robotics. I upgraded the laser from a wal-mart cheapo with the buttons taped. Aixiz lasers are inexpensive and very easy to use. The aluminum mount is taped to the pan tilt kit.

I actually bought my laser parts through eBay

The arduino and radio shack project boards are housed in a plastic bin I bought from wal-mart for a couple bucks. I hung it on the wall with a piece of decorative ribbon swiped from my girlfriend’s wrapping bin. I wanted to see the cats attacking the laser, so I dug out my webcam.

And of course they fall asleep when I’m ready to test it.
