Because the LEGO Rotation sensor is a powered type, it might be slightly
sensitive to battery voltage. I wonder if you notice the skipping is worse
with older batteries. Also, the problem might be aggravated by long wires.
Does the skipping get worse if you deliberatly add a long connector wire to
the circuit? The World Shop rotation sensor I ordered has a short wire while
the original one from Pitsco has a much longer wire.
