: Hmm...now you have me thinking.

: You could probably use a cam on a shaft and one of the push button switches. Read the pulses when the cam triggers the switch, and work backwards to get your speed.

That solution might work for a shaft which is rotating very slowly; I can't imagine
it working at all on a drive train. Well, you could drop the speed of the cam with
a large gear ratio, but then the precision would be so low as to be virtually useless.

If only we had interrupts...
