Hey Dan,
I sent a direct email to your address on your webpage concerning these, let me
know if you didn't get it.

| I managed to find a small collection of 12V Solenoid valves. I have been working on trying to get them to work with the RCX Brick. The voltage output of the Brick is pretty low. I have been able to get very good success using just a battery pack and (...) (25 years ago, 4-Feb-00, to lugnet.robotics)
