I need some help. I'm making a "needle rifle" (similar to a Halo needler, only green needles and it's a rifle) for a (working) prop. I made a few drawings of needle guns I could (or could not) make (depends on If I can work out a few kinks). The one I'm farthest in development on is the weapn seen on the bottom. This is a needle rifle. I want to mod a Nerf gun to shoot green darts (hopefully illuminated by glow in the dark, LED, etc...) and APPEAR like it's shooting needles (dyed plexiglass spikes) from a wheel that spins and "regrows" (not really) needles. I need a Nerf/Air Blasters/Air Zone dart gun that is motorized, rapid fire, and loads by inserting the individual darts into the gun when opened (no clips or ammo chains- although, good idea for a different needler gun design...). So here's my question- Which gun do I use, How do I integrate it into/around the "needle wheel" thing, and does anyone know how do make Nerf darts (suction cup/tagger/sonic/whatever works is great) actually light up? If it helps, I've got a zillion of these button cell batteries that seem to be the same diameter as a standard Nerf dart...Would an LED work? Also, if anyone has any ideas for a dart gun to use for the other guns in the drawing, it would be great if I could get some help with that as well.
