DIY Audio Spy Laser

Alen from wrote about this laser listener device. A microphone is simply a diaphragm that vibrates with sound waves. The theory behind this device is that when people are talking in a room, the window will vibrate. If you shine a laser on the window, it will bounce off with the same vibrations. Using a cadmium sulfide photo voltaic cell connected to a stereo plugin, the laser can be converted to sound recordings. View this cool DIY project here.
