Laser Audio Transmission with L-Cheapo

in: lasers

The L-Cheapo laser cutter can do more than cut, engrave, or burn. It can also be used for direct-beam audio transmission! Make sure your goggles are secured for this one!

The build was an L-Cheapo Mk4 with an LM386 preamp, feeding the PWM input for the laser cutter. The schematics for both the laser and the preamplifier are available on the L-Cheapo wiki page

Excuse the camerawork in the video, we were having a bit too much fun with this one.
