Finally finished is the prop weapon for my Fallout-based costume. I can't afford to make exact replicas (and in some cases, I preferred doing alt designs). The power supply is held by a belt (maybe some shoulder straps later). the spring-wrapped wire is connected to it, leading to the rifle part, which was made from an air rifle, some fuse boxes, a microphone and a 75 ohm low-pass filter. The power supply has an mp3 player and a battery-powered speaker.
