Don’t run it too quickly or too slowly. http://www.sjbaker.org/steve/lego/rotation_sensor.html

Um, that’s all I know, besides using BrickOS which has code to make it more accurate. You mentioned that already. Actually, now that I think about it, BrickOS might be able to run assembly language functions since it’s C++ anyway.

Two problems:

1. From what I’ve read about the problem, the speed I ran it at was right in the “sweet spot”.

2. BrickOS would not qualify for the competition.

I wonder if (hope?) the recent unavailability of rotation sensors at Pitsco is because the manufacturer recognized the flaw and has changed the manufacturing process to improve it. Trouble with that theory is, I suspect it has to do with the whole method of reading the sensor, which would require a firmware update as well; not too likely this will happen in that case. Unless there’s already a (poorly implemented) compensation for a sample coinciding with a voltage transition, which they can improve in the sensor itself.

Does anyone know? I wish they wouldn’t play so “close to the chest”; computer companies have long since realized that’s not a good way to do business.
