I've been employed by an E-waste recycling company that employs people with disabilities, my first task was to build a machine to break up CRT yoke ferrites, so naturally I had to sneak an Arduino in.
The rig I built is a beast, pneumatic powered cylinders that crush the yoke coils and drops them out the bottom.
It's only about 30 lines of code to control 3 cylinders.
I'll take some photo's and video, post them tomorrow.
This is THE most seriously physical thing I've built in ages!
