We absolutely LOVE the new LEGO Star Wars sets that have come out over the last couple of years. They're well designed, fun to build, and look great. What would make them even more fun is if they also moved on their own!

We took an off the shelf LEGO BB-8 set and automated it so the head spins around! Even better, we added sound effects and lighting effects! But if that isn't enough we also added a motion sensor so that it would activate when someone walks by.

Overall this project isn't overly difficult to do, but does take awhile and requires a healthy amount of random Technic LEGO parts to built the gear box area. We're using LEGO compatible Crazy Circuits components and a few parts from Amazon. All components are either readily available or Open Source. (Crazy Circuits parts are 100% open source!)
