Many years ago, there was an article in the back of Scientific
American about making a grandfather clock keep great time. Anybody
else remember that one? Got a date?
I think the pendulum had a small magnet on an arm going through
a coil with some circutry to pulse the coil in sync with the
correct time. It would gently push/pull on the pendulum to
dudge it in the right direction.
I wonder what a modern version would use? Obviously, the source
of "correct" time would use NTP. How would you push/pull the
Robot arm to add/remove coins?
A puff of air aimed at the pendulum?
Vaccuum pump to reduce air pressure and hence drag?
Heater to tweak the temperature slightly?
