How did you power the LEGO light Rob? Did you wire the light sensor itself
to the light, thereby using the current that the RCX sends out to active
sensors to power the light? Or did you use an external battery box?

| (...) Battery box. Running ot off of the power supplied to the sensor is an interesting idea, but I doubt it would work very well. The light is brightest with a full 9V. I think the light sensor only recieves 5V or less. Rob (23 years ago, 26-Feb-02, to lugnet.org.ca.rtltoronto)

| (...) Man, that sucks. I loved your robot, and I really wanted to see it work. hte design was just beautiful. Maybe you can keep it together and show us all sometime? Maybe we will do pick and place again? I, for one see lots of room for improvement (...) (23 years ago, 24-Feb-02, to lugnet.org.ca.rtltoronto)
