I started making a mini plotter based on the Arduino platform mostly because I was cleaning the storage room and I found some old cdrom drives laying around. So instead of throwing them away I thought that it would be a good idea to use
Brilliant idea! A robot that writes poems to sidewalks with sand! In four hours it can write up to 160 meters. It is built from a cnc milling machine. Have a look at the video:
If you still have some floppy drives around Richard Harris is showing you how to make a small cnc in a ten video series. As you may know in order to make a cnc you need stepper motors. Floppy drives were using stepper motors so
