Fun with a laser, servos and microcontrollers

This is actually not a robot, sorry. But.. If you have an old laser-pointer, and are building robots:

 

• Hook up the laser to the microcontroller. Now you can tuen on/off a laser
• Set one servo on top of another, now you can control 2 axes
• Set a mirror on one servo, point the laser to it..

Now you can precision-control where your laser points, if it is on / off etc. There are a million posibilities. Video is from when I was setting up a game of "pong" / "TV-game" so I could play with friends on large buildings at night ;)
