No expensive lightboards or sound packs here. This is 100% homemade and on the cheap.
Here is a couple stills of the final pack.
Step 1: Costumes
Flight suits off of Amazon.com
Paratrooper Belts off of Amazon.com
Boots off of Amazon.com
Then a couple custom patches off of Ebay to read 'Hogan' and 'Morrison' and of course the No Ghost symbols and we were pretty much good to go!
Just a few details needed adding like the gloves, circuit board (which were junked old sound cards) and some random tubing which can be found easily at Home Depot.
But in making a Ghostbusters costume remember...90% of the work in the pack.
Step 2: Cutting the Motherboard
Step 3: Sculpting the Parts
So we cut our parts out of insolation foam. This stuff is very dense and very pink. And perfect in terms of weight and ease of use. Jess and I had both used this stuff while at art school (SCAD) and with a little work you can get some great results.
But we also went one step further to really get things smooth and the corners sharp by coating each piece with spackle and then sanding it down. This really is the key to getting a foam pack look like machined parts. It even leaves a very nice and subtle texture that really feels like steel machined parts.
Then by adding a couple pieces of PVC you start to really get down the shapes needed for an authentic Proton Pack.
Again Home Depot was the store of choice.
(These are obviously just a couple of the parts we made, and don't include the battery pack etc.)
Step 4: Dollar Store Heaven
Step 5: Bumper
Step 6: Getting Ready for Paint.
So to prevent that we gave it a protective coating for Gesso.
There are some water based spray paints out there made by Krylon, but we had a hell of a time finding Matte Black. This stuff tends to spray on kind of runny anyways, so this is the preferred method we found.
(Other random parts on the packs include a Radio Shack project box for the mounting of the Wand, and craft wood ribbing glued onto the appropriate parts)
Step 7: Back in Black
Step 8: Light 'em Up!
This should be treated as a separate project as it did take quite a bit of work, and should only be taken on by someone who has soldering experience.
The battery pack is a simple chaser circuit, and the Cyclotron is just 4 blinking LED's daisy chained together each with a slighly higher capacity capacitor.
To make life easier I went ahead and just purchased ready made kits at [ AllElectronics.com]AllElectronics.com. Just dig through their LED and Kit sections and you'll find tons of fun stuff to play with.
We then put them into the pack and were ready to move onto most expensive part of the pack...
Step 9: The Gunbox and Wand
I ended up needing around 7 lbs of silicon to make the mold which ran me $125 for 10lbs. That was the big expense since I had to order it online. The resin you can find at pretty much any craft store and was only $25-$30.
Then with a little sanding this puppy was ready to go.
The grips were handles found in the gardening department at Home Depot, which we then spray painted matte black and wrapped in standard electrical tape.
All the little parts on the gun were made out of sculpy. And the same approach was taken on the pack as well.
Step 10: Alice Packs
Step 11: Wiring It All Together and Finishing Up.
This took a few hours to wire up each one and resulted in a rats nest of wires inside, but it got the job done. Electrical tape and hot glue is your friend during this step to prevent any shorts.
I added in a LED Bargraph that lights up and also a tri-color LED in the gun tip, which was made out of a turkey baster found at the Dollar Store.
Step 12: Demo Video
Step 13: Random Stills
Plus it finally fulfilled my childhood dream of owning my very own Proton Pack!
To end here are just some random stills of the other parts of the packs not mentioned in this instructable. Oh and also my cat because she's awesome.
