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:
What started as just the Neutrino Wand has turned into building a full pack for my son this Halloween. The goals were pretty simple. Replicate the movie pack as best as I could, keep it low weight, and give him some stuff to play with. Here is what I came up with…
The result is about 80% scale, around 8 pounds on the back, and completely mirrored as my son is left handed. The pack is 3D printed using a PVC backpack frame and some other odds and ends to finish it off. The lights and sounds are based off an Arduino Nano that is controlling a bunch of Neopixel LED’s and an Adafruit Audio FX Board. The entire code, models, and PC boards used can be found on github here:
Now that the PKE Meter is finished I’m starting in on the full proton pack. I found a really good base to start with on Thingiverse. DancinFool82 did an amazing job on the 3d models for it but I need to make some modifications to meet my needs and make these models printable on my Davinci Mini. I’m just starting in on the base of the Neutrino Wand but I’m really pleased with how it’s coming out.
My son has decided that he wants to be a Ghostbuster for Halloween and I have my work cut out for me. I found a number of plans on Thingiverse for proton packs, traps, and PKE Meters and decided I’d take a crack at one of them. I originally thought the PKE Meter would be the easiest so I decided to start with that. About a month later I’ve completed it and it looks like this
