Building and Playing a Laser Harp! Cali Lewis October 29, 2013 Episodes What’s a Laser Harp? While we were in London, my friend Steve Thompson showed me his awesome laser harp! It uses a single laser, but the beam moves super fast, making several visible beams, which you can then interact with. Each beam has a MIDI file associated with it, and when you break a given beam, that sound is played. It can be just a single note, or a song sample… whatever you want! And the pedal boxes on the floor can give you even more control. Steve put the entire package together for a little over £1,500 (about $2,400). Want to Build Your Own Laser Harp? Check out these instructions from the Artisan’s Asylum hackerspace in Massachussetts that lays out the steps to build your own laser harp.
