The CSV19 Compact Low Cost

Systm is the Do-It-Yourself show designed for the common geek who wants to quickly and easily learn how to dive into the latest and hottest tech projects. They will help you avoid pitfalls and get your project up and running fast. In this DIY episode, see how to build a compressed air tennis ball cannon.

300 yard tennis ball hucks? No problem. Your questions about calculating barrel to air chamber ratios, finding fittings and what exactly Schedule 40 is? No problem. David's new Versalaser? Problem: he's out sick!

On our big cannon, we went with an air triggered 'turbo charged' sprinkler valve. We also went with RainBird sprinkler valves, which seem to moan a lot less than the Orbit valves we used for the smaller cannon. Doomlabs Turbocharging Sprinkler Valves was invaluable for sorting out how to tweak the valves for more oomph.

The downside is that this makes it super easy to accidentally release your tennis ball. Always point it down range. The dual electrical switches in the smaller cannon are definitely more safety conscious.
