His Rubidium-standard atomic real-time clock is surely an example of hardware ... frequency counters so he went with logic chips. The pictures and a few video annotations are the only clues ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block ...
