Here are some pics of my complete for Halloween 09 proton pack. I use the word “complete” loosely, because there are quite few details wrong or missing, but I ran out of time and went for “close enough”. 
I wasn’t going 100% accurate, but wanted to come close. I used Pink Foam as the base for a lot of pieces, as well as Wood, plastic, PVC hardware store parts, stuff off the floor of my garage, etc. The wand body is wood blocks glued together, with PVC pipe.
I scored a real ALICE vintage pack frame from a surplus store, and added some lighting effects with christmas lights and a kids safety wand for the gun. I will post some build pictures later. I used a combination of all three sets of plans for the pack and wand, using whatever made sense at the time.
The stickers really made this look great, so thanks to bobamatt for the awesome work. Also, thanks to the site and the makers of the fine set of plans made available here, I would not have been able to do it without you.
