    My opinion on my last post on this subject has changed.
    Brighter minds are posting here !
    I have an old 1886 riverside movement that I’ve put into a plastic case and mounted an electret microphone into.
    I plugged that into my computer’s sound card and can hear it ticking all over the house !
    Next phase is to hook up my oscilloscope to it with a digital counter of some sort.
    Minor variences of speed are too miniscule to view directly on the scope.
    Just had an idea.. Computer’s bios system fan speed is basically a counter.
    Need to input a rock-solid frequency into it and reset it with the tick of the watch.
    Or some sort of configuration.
    Think I’m gonna go there….I’ll post info and results….
