Holy... Never seen this before! So the tube is hooked up to software that pulses it at different frequencies, but is the sound being generated from the wood burning and the gasses that escape are producing the frequency? Or is the tube itself vibrating?
Kinda , Its a Arduino driving the Co2 PSU with Sqaure wave notes , The sound can actually be heard from the PSU , Tube and the Spot its self ,
The burn spot is loudest source of the sound ,
I'm wondering about this too, is it current flowing which sets the music to play, or an optical sensor seeing the light? I'm disappointed they didn't show the laser tube itself.
Its my video and channel ,
Tube can be seen here - https://www.youtube.com/watch?v=42gJZ07qcTU
