 Well,
I finally got the video editing software up and running on my
new machine so that I could put the video of my air cannon here.
It was built to test an idea for an episode of Robot Rivals.
The entire cannon was built from parts that I found at my local
hardware store for about $55. It has 11' of 3" SCH 40 PVC
rated to 330 PSI for the accumulator. It goes through a 3/4"
ball valve that is sprung open with a bungee cord and then into
a 1 1/2" 160 PSI PVC barrel which just happens to fit a golf
ball perfectly. The reason for using a mechanical ball valve versus
a solenoid valve is price and flow rate. To see video of it in
action click here or head
over to the Videos page. |
