Old, staying for reference [Pneumatic PickUp Claw]

A few dys ago I received a bricklink order. It contained one pneumatic cylinder, a switch and a compressor.

As I was thinking about what I could possibly build with only one cylinder I thought about making a pneumatic pickup claw! Right before I started designing the claw I built a compressor. It is powered by one power functions M motor, p.s. it’s not my design-I saw it somewhere  over the net. To save energy, and make controlling the claw more efficient  a comfortable, I hooked up the PF switch with the pneumatic one, so when one is off, the other is as well. It prevents the compressor from compressing too much air, by ativating the motor only when the pneumatic switch is on (works for both sides).

The videos and pics will explain the rest….
