Does such a thing exist? I'm thinking electronically triggered soda-stream cartridges installed in the arms of my Iron Man suit with a pipe leading out to the repulsor LED's in the palms of the gloves. My LED's, when activated, wind up in brightness, reach a peak ridiculous lumen then wind back down. Sound too. I'd like to tie in some sort of electronic trigger/solenoid? To fire the Co2 just as the central LED blasts full brightness, illuminating the white plume of Co2 My electronics guy, James is all over the electronics, we just need a few ideas/direction on what's commercially available out there. The closest I have seen is bicycle tyre inflators, but they are all activated manually with a wheel or push-pressure. Anyone? Baz.
