Newbie here. Is this "fiber-optic lights unit" the same as the rotation
sensor that's now on the Mindstorms page?
Has anyone tried turning the light sensor into a rotation sensor by
building a shaft encoder? Face the light sensor into a 'tunnel' and put
a (four bladed?) 'fan' in front of the other tunnel opening. You'd get a
pulse off the light sensor every quarter turn.
