| (...) My guess (having never looked at the schematics, or taken one apart) is that when connected backwards, "dark" would be 0V and "light" would be -8V. Again, a simple bridge rectifier (this time in the RCX) would get it sorted out. It might be (...) (23 years ago, 4-Feb-02, to lugnet.robotics)

| (...) No, there's no bridge in the RCX, just a pull-up to 5V (10kOhm IIRC). If you look at the schematics (say at (URL) see that there is another bridge rectifier in the sensor between ground and the raw sensor output. The ground half of the bridge (...)
