DIY Hacks & How To's: Laser Tripwire
No security system is complete without lasers. We have all seen movies where the main character has to get past a high tech security system and there is always a room full of lasers somewhere.
So in this project, I show you how to build a laser tripwire alarm. All you need is a cheap laser point, a couple of mirrors, and a few dollars of electrical parts. With this you can cover an entire house with an array of light beams. If any one of them is crossed it sets off your alarm. And unlike in the movies, these lasers are practically invisible.
