Build a DIY Arduino Can Crushing Machine
Banging over the head with cans is great fun, but if you really want to impress everyone around you, doing it with a car you built yourself is much more fun.
At Make, they walk you through building this DIY crusher, from coding to getting the drive to work properly. This is all pretty easy to build, and while awfully slow, it’s still a project that teaches you a lot about how all of these components work together. Plus, it’s just fun, even if it takes 60 seconds. Go to Make for a complete guide.
