Default Air cannon test video
Here is a quick test video of the air cannon that I am building. It needs a barrel, paint, and a switch installed - but it is getting there. This test was at 80psi. I used a $13 sprinkler valve and am happy with the results. There isn't a BOOM, but there is a loud WHOOSH and no honking.

I'm not quite sure why it doesn't honk. I've tested it between 20-90psi at 5psi increments. My guess is that the honking is eliminated by either the valve that I used, or the power supply. I will create a build thread outlining all the parts with pictures once it is complete.

What brand valve did you use? This is on my project list this year and I've heard from several people to not go that route because of the infamous "honk". I would much prefer to be able to shoot down to the Depot to get all the parts and just get it done.

Looking forward to the how to.
