I suppose we could ask for help also to non-legos owners of RCX and rotation
sensors. What if any of us posts a message in the robotics newsgroup asking for
some reads of rotation sensors? Raw values can be read with the sandard
firmware too and then we will scale them. With a set of values a bit larger
then mine we can probably set up legos constants to make them more general.
