Several years ago (OK, the last millenium) I GPS disciplined a friend of mines
200 year old grandfather clock that she had inherited. I used a solenoid to
nudge the pendulum. Surprisingly, it worked quite well the first time. The
biggest problem was the pendulum did not swing at a 1Hz
Bert,
Thank you for posting your project info!
One of my hobbies is collecting and repairing clocks. For several years
I've been thinking of making an add-on device to discipline pendulum
clocks. I've been using PIC based circuits to provide pendulum impulse.
I've not tried to discipline the

Hello Bert,
It is good seeing this in motion.
I have had this project in mind since I read the article in Scientific
American,
A Venerable Clock Is Made Highly

Hi Bert,
Thanks for posting that project. What a wonderful combination of electronic and
mechanical timing, of design

which I control with PIC micro firmware and try to mainain at a constant
temperature. Accuracy for 20-second averaging is typically
