Cheap Laser Target Finder Sensor
http://www.philohome.com/sensors/lasersensor.htm
Just as I was going down this exact road, I found this: someone else beat me to it, 5 years ago! Usually that honor goes to Phil Pilgrim...
Clever app; cheap laser pointer plus $4 sensor senses reflectors for direction & triangulation (not distance). This guy likes Legos and incorporated the idea nicely inside a brick. A VERY well-done web page with thorough step-by step instructions.
Don't·miss the final link to a webpage with info, photos & cool video of Daniel Rojas' missile launcher (duplicated HERE ).
