I've updated the hardware interface for my homebrew rotation sensor. On
Sven Horstmann's suggestion (he said it was originally Bob Wind) I tried
using a LM339 comparator in place of the LM324 Opamp. The LM339 did the
trick. The RCX never looses counts unless you spin the shaft really fast.
The new circuit is at:

Thank you Sven and Bob.
