I want a general purpose basic pneumatic system that can be programmed to use
any of the three positions of the pneumatic valve.  I modified the Brian
Alano valve control design by adding a revolving drum (I think Lego calls it a
"round brick") that hits a touch sensor as the valve moves between the three
positions.  Details are at

Hi Walt,
  When you say it "misses a command", do you mean that you don't get the touch
sensor pressed once in a while?  Or the motor doesn't turn when you want it to?

  If it is the touch sensor issue, maybe the round brick+boat plate that are not
close enough to the touch sensor.  Maybe you could make that spring loaded?

  Or is it that the switch is misaligned when the touch sensor is pressed?
