In this video, Jon Bumstead demonstrates his Upright Laser Harp instrument.
The Upright Laser Harp is a custom design, based on an Arduino brain.
In the first part of the video, Bumstead demonstrates performing with the Upright Laser Harp. In the second section, he takes a deep dive into the details of the instrument’s design.
Heres what he has to say about the instrument:
“In this project, I built a laser harp with stacked laser beams that propagate horizontally. The beams reflect off mirrors to form square shaped beam paths.
Instead of a MIDI output, like my previous laser harp, this device has built-in MIDI player so the output is an audio signal. This means the device does not have to be connected to a computer or MIDI player (e.g. keyboard) to play sound.
Both built-in speakers an audio output jack are available for playing music.”
