Re: Ways of using compressed air to shoot the ball

See my team's history section, 2008, for our track ball launcher: http://www.frcteam95.org/wp/history/

A close-up of the two-stage piston launcher:



If memory serves it was capable of launching the track ball 10-12 feet in the air. The trick is using many small pistons (and thus many solenoids) so that air flow into your launching mechanism is legally maximized.

Just cite your source please
