| | | I have been searching for the answer to this one for a while. My intent is to find a supplier who has small electrically operated (solenoid) valves which can be driven by the RCX output(s). I have found one so far, but the valves are very pricy. But (...) (25 years ago, 21-Oct-99, to lugnet.robotics)

| | | | I'd love to get a hold of some small RCX controllable valves also. I just finnished building a six legged pneumatic walker that would benefit from these for different walking motions.
