There was an article in Scientific American Sep 74 describing a nice hack to
synchronize a pendulum clock to a quartz crystal. They attached a magnet to
the pendulum and then pulsed a coil at the right time. It was the typical
Amateur Scientist level of detail.
Some pack rat on this list (I think) sent me a scanned in copy. I can send
it to anybody who wants it.
