Pretty cool looking build that got my attention, thought you guys would like.

[over9k] used his Arduino to set up a laser trip wire. The laser is mounted along side the Arduino, reflects off of a mirror, and shines on a photoresistor that interfaces via a voltage divider. The signal from the voltage divider is monitored for a change when the laser beam is broken. [over9k] set things up so that a webcam snaps a picture of the intruder and Twitters the event for easy notification.

Lol, nice.

Disclaimer: when i was 14 i has the LegoMindstorms 1.0 kit with the optional lego usb camera, and i set it up to catch my little brothers sneaking into my room to touch my stuff. It's easy to get them in trouble when you have video proof. LOL.

This is cooler though. It involves lasers!!!
