Laser Harp I made! Looking for feedback, please share any thoughts :)

A LEGO enthusiast created a custom Laser Harp using an Arduino UNO and the ChucK musical programming language and is seeking feedback on their design. The creator hopes to market this innovative product as an educational tool, potentially as part of LEGO Education or LEGO Mindstorms.

The Laser Harp features six horizontal "strings," each consisting of a pair of laser diodes and light sensors. The design incorporates velocity sensitivity, meaning the volume of the notes changes based on the speed of "plucking" the strings. The creator demonstrated the harp playing an E major pentatonic scale, but all musical and audio parameters are customizable.

The creator is open to suggestions and ideas from the LEGO community and is eager to answer any questions about the project. The ultimate goal is to integrate this unique instrument into educational settings, possibly as a new addition to LEGO's educational product lines.

If you are interested in building your own musical creations, you might find a LEGO Technic set helpful for experimenting with gears and mechanisms.
