I'm not sure what you mean by "making light sensor passive". The light sensor, by design, requires power to work. You can tell the RCX that the light sensor is a passive sensor, but you don't get much range in readings - the phototransistor in the (...) (26 years ago, 25-Feb-99, to lugnet.robotics.rcx.nqc)
