You could cruise the Internet bazaars for a talking clock but you’ll never find one as awesome as this. Just look at it… even if it didn’t work it would be awesome.
[Art] certainly lives up to his username. His Rubidium-standard atomic real-time clock is surely an example of hardware art. The substrate is a collection of point-to-point soldered perfboard modules. Each laid out meticulously. What does such layout call for? A gorgeous enclosure which doesn’t obscure your view of the components. For this he went with a copper tube frame and a custom fabricated aluminum chassis pan.
For the circuit itself [Art] tells us he wanted to build something akin to the old HP nixie frequency counters so he went with logic chips. The pictures and a few video annotations are the only clues we have for how this works. Hopefully your encouragement in the comments will help prompt him to share more about that.
Oh, and the talking clock part that we referred to earlier? Every minute you get a readout of the time thanks to a PIC playing back audio using [Roman Black’s] BTc sound compression algorithm.
