Sure, and glad to know others get spooked by things apparently moving out of
the "corner of the eye."

George, I agree that analog readout is preferable to a LED for observing
while turning wood or driving a car; as opposed to setting a certain
speed. Could Steven at reasonable expense, observe the changing rpm in
analog form while he is turning and simultaneously store the data in
analog form. Then at a reasonable expense later, have it processed for
computer use with someone else's AtoD and digital scope? Arch
