Re: T-Shirt cannon AC problem
Our experience with the 24vac sprinkler valves is that they operate just fine on 12vdc. That is, if you only power them long enough to launch the shirt. We used a Spike relay to power the valve. It can easily handle the current and has no problem cycling the valve quickly.

We found that you can actually save a lot of battery drain by just cycling the valve open for .1 seconds. How does that save on the battery? In our case, it prevented us from having to completely recharge the pressure tank. Leaving it open for one full second would drain the tank.
