I have a ROTJ Fett underway and I'm really wanting to get as many working parts as I can on the suit. So far I have an integrated voice amp/mod in the helmet, working range finder flashing LEDs on a mercury tilt switch, (parts on the way to lower and raise the RF with a switch) left gauntlet arming light, flame tube pilot light, laser targeting sight, chest lights of course and on the jetpack light up diffused thruster lights. I've been playing with and trying to figure out some kind of remote CO2 propellant system to shoot bursts of 'smoke' through the bottom jetpack vent. I've all but gave up on it but thought I'd see if anyone has any suggestions or ideas. I'll attach a couple shots of my pack for fun, it's a MOW with my paint work
