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….
