I appreciate the comments regarding horological obsession. Mine started
with a desire for an accurate master
oscillator for my ham shack (built and use a couple Shera GPSDO's) and
has
blossomed into a much broader interest
As I type this, my solenoid actuated mechanical slave clock is being driven
by my GPS receiver. The 1PPS signal drives a two stage divide-by-sixty
counter. The two counter stages, 7490 divide by ten and 7492 divide by
twelve used as a divide by six, are interfaced to two large Nixie tubes
Hi Tom:
I've been looking at patents for secondary clocks and find that there's two
class numbers: 368/59 is Horology/Secondary and 968/548 is Horology/stepping
secondary.
Do you know what the difference is between the two top class numbers both
called Horology?
Have Fun,
Brooke Clarke
...And i forgot one thing...
The Telechron solenoid assembly is symmetric and
reversible.
That allowed some manufacturers to sell Bar clocks
that had their hands run backwards!!

Hi Mark:
There may be some other approaches.
Start from an electric clock that's battery powered and replace all the
driving electronics and just drive the coil directly with the proper
pulse rate.
Start from an electric clock and replace just the crystal with a 32768
kHz signal.
In the above

But one easy way to do it today is start with a $5 standard
quartz clock display. 1) Either run a precise synthesized
32 kHz signal into it (replacing the xtal), or drive the little
bipolar stepper yourself.
A 50 millisecond +1.5 VDC pulse is all you need;
