"A reverse-engineered typewriter hack to make it into a printer. Using a simple MOSFET circuit and an Arduino (actually, a Light Blue Bean+ arduino compatible board), I reverse-engineered my IBM Wheelwriter 6 typewriter to print out text and some rudimentary graphics. The GitHub repository is here, and I'll continue to update it with schematics, etc., when I get some time: https://github.com/tofergregg/IBM-Wheelwriter-Hack"
