I’m researching a theatrical special effect that is essentially a confetti cannon on your wrist.
So the givens. I’d like to mount a CO2 cartridge on a wrist board. It would connect to a valve which would evacuate a cylinder packed with confetti.
There are projects on the web which do this. But they use a plumbing bulky lever valve to open the gas into the load cylinder.
So I’m investigating an electrical valve. The parameters are that it must be rated for 900 psi AND be operated by low voltage (I’ve seen 12V valves) I’m sure this would be less bulky than s plumbing cut off valve AND be easier for the actress to activate.
But what I haven’t seen are current requirements. I was thinking of running it of a USB battery pack. But, will a boost circuit up to 12V have enough current to operate the valve?
Please help!
Thanks,
Don
