Back in December I was looking for the next project after the proton pack. I knew I wanted to build a robot but I wasn’t sure what I wanted to do. R2D2 seemed like a lot of work and then I found some files for Chopper from Star Wars Rebels. He’s a bit shorter than R2 and I wouldn’t have to worry about trying to replicate a perfect chrome dome. After a lot of reading and joining the astromech.net forums I started printing. All in all over 15 rolls of 2 pound filament was used. I did learn a few tricks to speed up the process.

Spirit Halloween recently released a pretty nice proton pack replica for a really good price. There are a few issues that I have with it though. The lighting they included is not very good and there are some real issues with the way the wand is mounted. These issues needed to be fixed!
I had a bunch of extra components lying around from the full proton pack so I got to wiring. I wanted the standard powercell and cyclotron animations while I walk around. I kept the flashing light in the powercell when firing the wand but removed them on the cyclotron. The result can be seen here:
The full Arduino code, 3d models, and diagrams for this mod have been added to my github repo and you can find it here:
