Surely you can find a proton pack on ebay! My little brother had one. Well, it was a cartoon one, not a movie one. But modifying that would still be easier than starting from scratch.
After numerous set backs, broken promises and general fuck-ups I am now re-assembling my place. It is slow, arduous work. Apologies if I'm incommunicado this weekend, but I need to get this place livable again.
