So I have revamped Runamok 'Bot with 40 tooth gears for a great speed increase. And the rotation sensors are still accurate at this increased speed. Now, however, the light sensor misses--could be the codeing or the light conditions in my room--so (...) (23 years ago, 13-Feb-02, to lugnet.org.ca.rtltoronto)
