HELP! i need help with sound activated flash!!!

Hello, i have recently been intrested high speed photography. I have rigged a cheap external flash to be fired when you tough two external wired together. I wanted to make some kind of circuit that would trigger the flash when there was a loud sound.

Convert airgun/Paintball gun to be fired by a computer (12v solenoid valve)

Hi!I have a project this summer where I need to convert a paintball marker and a co2 Airpistol to be fired by the use of a solenoid valve powered by 12v.The project goal is high-speed photography, more or less photographing object being hit by a projectile.What i need is a way to fire these guns precisely by the use of my computer and software, and since I already have plenty of 12 solenoid valves that work with this system I thought my easiest way is to adapt these valve to trigger the guns one way or another.I just purchased a Valken V-TAC SW-1http://www.valken.com/Marker-V-TAC-BLACKHAWK which I plan to use as base (for parts) My reason for getting this particular one was that it was on sale for 50% and seems to be fairly popular as it's based on the Tippmann 98 design.I attached an image of the valve I used with my controller and software (Cognisys Stop shot) now I can probably use any 12v solenoid valve (with the same spec ?) as the one I use now so it doesn't need to be these exact valves. As long as they can be operated by turning on-off power with the same powersource i use to control my current solenoid valves.From my understanding, most airguns use a pin valve, which is hit by a trigger mechanism that is then rearmed by the blowback.What would be the best way to modify an airgun for my needs? Replace the pin valve with a suitable solenoid i can control instead? Or go for a design that uses maybe use a piston and 2-way valve to hit that pin?The gun does not need to be mobile or ergonomic, it will be placed in a rig regardless, however keeping the barrel and keep the Picatinny is preferred to be able to mount marking aids etc. and mount the gun to a tripod.Any tips or suggestions are highly appreciated!Thank you!
