Laser Deflection Unit
thingiverse
This project is a laser deflection unit that can be controlled with two steppers. It's designed to teach students how to work with microcontrollers effectively. Additionally, there's a disc with a 4-quadrant photodiode as part of the system. In the git repository, you'll find code that controls the laser deflection unit so it always points to the photodiodes. I've only uploaded the essential files for the deflection unit since this is the part most people can use for other projects.
