Hello,
I want to experiment (just for fun) with a PC controlled percussion player mechanism. Initially I want to play with a small solenoid valve connected to a small pneumatic piston. Piston will drive the hitting arm. I think max actuation/hitting rate would be around 20Hz. (Is this rate reasonable?) (I do not have any hands on pneumatic experience. That's why I've considered starting with pneumatic, so I can learn more)
How to control the hitting force in pneumatic system ? Can you recommend (low-cost) small/miniature solenoid valves and pneumatic pistons etc for this experiment? Any other suggestions?
