Arduino Laser Show using real galvos

This video shows the laser show I did with an Arduino Nano and commericial 20Kpps galvos. The whole project is available on: http://www.instructables.com/id/Ardui... so you can build the laser projector yourself! The source code is available on Github: https://github.com/DeltaFlo/LaserProj... Music by BitArts (Red Sector Mega Demo, 1989, Public Domain) It actually looks a bit cooler in real life. I had trouble filming it with my camera, since it always re-applies auto focus when the show is dark for a moment. Human persistence of vision is much better than any camera!
