Re: [Phys-l] Fwd: SB Courthouse tower clock now on the web

Which reminds me - a miniature atomic clock is now an article of commerce,
I notice in a design magazine. Requires reasonably stabilized low voltage, emits 1 pps
at an accuracy rather better (X100) than the best TCXOs. Measures an inch or two square.

In small quantity costs ~ $1500
Not quite as stable long term as a GPS driven clock but still, works under water etc.

p.s. for those w/o a convenient IBM platform computer -- would you add the time tics and label on the graph; please?

p.p.s. your complaint of small pics of my first try: command + increases them to "pixillation".
