for those that didn't t get:
you should run the motor with the tape in the axis and partially hit the tape with something for some time (5-10 sec) recording the noise with some audio analyzer software.
then, in the software you just count how many noise spikes there are in a time space and adjust the math for one minute (ex. 100 spikes in 2 seconds = 3000 rpm).
great idea but you should improve your instructables
