Wow awesome! Glad to see other teams making T Shirt cannons!

We're building our 3rd generation cannons right now into our robot. Sprinkler valves are the best to release the pressure because they can be controlled by a spike relay. Fairly cheap too.

As for the pressure, we've figured out that all you need is a normal pressure switch. So that's usually 115psi-120psi. Between the pumps and the air tank reservoir add a pressure regulator. You can regulate the pressure and know what the pressure will be at, and the OI will receive the shut off from the pressure switch as you normally would.

I don't know if that's been posted before or not, I didn't have time to read all 60+ posts on this thread, i was just too excited to post. So if someone else DID post this, I do apologize.
