Instead of pushing a pneumatic switch back and forth, you can use the old non-return valve: (URL) the pump to the middle hole, connect the air tank to the left hole and leave the right hole free. The old style pump will pull air out of the tank and (...) (24 years ago, 18-Dec-01, to lugnet.robotics, lugnet.technic, lugnet.build)

In NQC, I can use ClearTimer(0) and Timer(0) to get interval of time, how can I do it in legOS? I used t1 = sys_time, then t2 = sys_time, so interval = t2 - t1, is it correct? Zhengrong (24 years ago, 18-Dec-01, to lugnet.robotics.rcx.legos)
