Yeah, I think they are WAY too expensive too. Try this though, use a
touch switch, about $10 most places, and one of the larger pulley wheels
with the 6 (I think) holes in it. Place the pulley on a shaft that the
wheel turns such that the switch is not triggered when the hole passes
over. Then you can attach a counter to that button and count the ticks
you get to determine position or RPM rate. This should be do-able in
"not too large" of a Rube Goldberg space...
