If you need to crush a bunch of aluminum cans you might as well build a machine to do it. That is what we see on the Ben Heck Show here. After Ben bent through a bunch of design submissions a cool design was selected. A single stepper motor crushes a can with a 30 to one gear reduction it can crush the can but isn’t able to crush the can completely. Not that the final design is ready for production but the design steps are very interesting.
