Hey guys!

I improved on the design of Sariel's autovalve compressor to come up with this:

It is pretty solid and works reliably. I have used the old style pneumatic switches:

It should be easy to use the newer type, but i dont have any to try it.

It currently powers only one pneumatic pump, but it should be easy to add another. The NXT motor has plenty of power to power more.

My goal was to be able to fully extend / retract a small pneumatic piston in around two seconds using the compressor.

You can download the .lxf file here:

The original design by Sariel can be found on his website here:

I'll make a video soon :)
