The main construction is based around aluminium 2020 extrusion. I’m using seven laser pointers and an MSGEQ7 to separate out and project seven frequency bands from an audio source.
A central piece of 2020 extrusion spins around – driven by a brushless motor. Each side of the 2020 has a mirror stuck on it in seven positions to correspond with each laser. The MSGEQ7 and Arduino MEGA control the positions of seven shutters attached to R/C servos which cause the projected laser line to change length.
