When a normal alarm clock just won’t do, the only option is to build your own, entirely out of discrete logic chips. [jvok] built this alarm clock for last year’s 7400 Logic Competition.

a high-speed clock. The fabricated chip has demonstrated how a self-timed network-on-chip can perform all of the functions offered by a more conventional system bus such as allowing test access and ...

The size, power, and other metrics of a latest-generation chip-scale atomic clock.

The processors had their L1 bridges lasered off to prevent users from changing the chip's clock multiplier. This was at least partially done in response to shady computer shops who were ...
