Very interested in something like this, ESPECIALLY if it's triggered by something other than bbs - I do film and tv and theatre work using airsoft as props, so I don't want any projectile at all, but I love the effect of the smoke and light together.
Is there a way to order to the US? An online store or anything? Any US distributors? Heck, if it can fit in a suppressor it could probably fit in the barrel of something like a CAM870 too, right?
I'd even be interested in just knowing how you did the sensor, so I could convert some of the spitfire tracers I've been experimenting with...
