This is an oldie, but oh, man is this ever good. It’s a Nixie clock made without a microcontroller. In fact, there aren’t any logic chips in this circuit, either. As far as we can tell ...

A while back we saw a logic clock that used the alternating current frequency from the power grid to keep time. We asked for information on your projects that use this method and we got a lot of ...

If all signals generated on-chip switch at the same time, the verification of the system is simplified: it has "only" to be verified that the delays from the output of the registers via the ...
