T-Shirt Cannon

[SamM]

We use one of these valves on our cannon:

A little bit more expensive than the sprinkler valves, but it's rated for air pressure.

Beside what is posted above 3" is to big. I think we use 1.5" or 2". It works great.

I wish I had found that one when my team was making our t-shirt cannon. We used a fairly similar valve, only 3 times the price.

this may seem stupid but how are you folding the shirts? if you just sort of shove them in the barrel it will open in flight like a parachute. However, there is a way to fold a $@#$@#$@#$@# to make it more rigid, if folded this way you can toss it, throw it, or shoot it and it will stay together. (PS, working on pics)

When we wired it to our PCM we keep getting a solenoid fault on it. We changed our program to a single solenoid as we were using a double. Just wondering if we had to do something different wiring wise as there is no errors in our program

Thanks!

The PCM may not be able to supply enough current for the larger solenoid. You may need to use a victor or another speed controller to supply power to it, which is what we did. You could also probably use a small automotive relay.

Great Thank you! So then we will wire the solenoid though the Victor to the PDP then correct? Thanks again!

[SamM]

Yes, just treat it as a motor and run it at full power when you want it to open and no power when you want it closed.

We switch the solenoid valves on our air cannon with a 12 relay module similar to this one. Our first iteration used a spike relay, with one valve powered by M+ and the other by M-, with a common 0V (ground) return.
