Laser Harp Is Frikkin’ Lasery

By Evan Ackerman

Laser harps aren’t, as far as I can tell, brand new tech, but you’ve got to admit, seeing a home built one in action is pretty cool. The principle is deceptively simple; a reflection sensor watches the beams, and when one is interrupted, it signals a MIDI routine to produce a tone. Sliding your hand up and down the beam can bend notes, or do anything else that you feel like encoding into the MIDI protocol. So, yeah, the music is great and all, but I think the best part of the video is the shutdown sequence at the very end. Hey, I wonder if he takes requests… How about Flight of the Bumblebee? No, wait! Free Bird!!!

If you want to build one yourself, it’s possible with some know-how, check out the website. Oh, and click here to watch an absolutely adorable video of how the harp works.
