(...) Thanks, Jen. I'll have a go at it. (...) Well, I was just thinking to what extent you could take the pressure sensor device. Actually, most of my own creations don't use the RCX. And they're mostly powered by the manually operated hand pump. (24 years ago, 10-Apr-01, to lugnet.robotics, lugnet.technic, lugnet.build, lugnet.dacta)
