I decided to make a mobile/large version of the proton pack for the car. I basically combined the Slammer with some Proton Pack designs...
I sat down and did some sketches to figure out what I wanted and it came out really close to my concepts.
I ended up naming it the MHC: Mobile Hadron Collider. It's nickname is "The Big Twinky"
It is intended for use only when a Ghostbusters team goes up against a Deity-based threat, such as Gozer. In most situations, the basic proton pack isn't strong enough to wipe out a God and crossing the streams is too dangerous to the Busters in question, so they resort to this large Ectomobile-mounted collider that is capable of generating a small black hole in the creature's vicinity. It then switches to a reverse-field generator, which replicates the affects of crossing the streams inside of a dimensional gateway(in this case, a temporary black hole about the size of a truck tire).
I started off with a few Dollar Tree parts and some L-brackets..
It all fit together pretty well. The main structure is just a 5-gallon bucket.
The Ion Arm is PVC board with a brass tube. I used some rubber/steel clamps, and red lume, among a few other odd parts. I also used the red canister from the Super Slammer from the video game. It also reminds me of the animated series Proton Pack charger.
I painted the whole thing silver and then gave it a coat of flat black, like a lot of you guys do with your proton packs. I then sprayed black weathering over everything with some silver to make it look used...
Inside this whole thing is a mess of wires and LEDs. The power light works on the front and I have a bright strobe that flickers inside of the top(you can see it though the small square vents) that I pulled a Dollar Tree pumpkin strobe.
Since it's a temporary addition, I wired the strobes to a small switch in front instead of connecting it to the car's power supply...
I plan to attach it to the rack tomorrow.
