This a screenshot from a movie I am working on, the pack is slanted on my back. And the proton gun is in my hands and the cable connecting the two doesnt show up in the shot. Its a rather low quaility screen capture. The pack has working lights, (on gun and backpack) Blue pulsing and Red circular, yellow lights on main box of gun. Tip lights up when triggered. The backpack vibrates when it is turned on from the switch mounted on the gun. The gun also vibrates when it is being fired, along with the light on the tip of it flashing.

(note I had to edit in the lights for this picture, they did not show through well in this screen capture.

Im still modifying the pack, I just ordered the correct ribbon cable and I am working on the booster frame.

When I get a digital still camera I will take some better pics. I am also working on implementing sound.
