 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Ben Eater is releasing a series of videos building a clock using discrete componentes running on the mains frequency. As always, using breadboards https://youtu.be/3XDH-fZKnQk?si=TVRP8ydjmcW_mwSK Edited 2026-09-13 04:25 by LeoNicolas |

Many moons ago there was a design in one of the UK magazines using, IIRC, digitrons driven by rotary switches and a geared synchronous motor to push them round every minute. The switches had their click stops removed and the shaft had a "star" of rods, one of which was bent to give a "carry" signal to the next digit's switch. Not a normal valve or transistor in it. :) It had a certain electro-mechanical charm but I bet the lifetime wasn't great. Mick Zilog Inside! nascom.info for Nascom & Gemini |
