Polargraph Plotter Built with Junk Parts @nycresistor

This weekend I built a polargraph from random junk around NYCR. It’s amazing how much stuff we have available for projects, if you just take the time to dig through our thingsgiving bins. This one used NEMA17 stepper motors and pulleys, a surplus tinyg board and a dry-erase marker suspended from thread found in the fabric bin.
