Building A Transistor Clock From Scrap

Hackaday

[Phil] has already built a few clocks with Nixies, VFDs, and LED matrices. When his son requested his own clock, he wanted to do something a little different. Inspired by the dead bug style of [Jim Williams]’ creations, [Phil] set out to build a clock made entirely out of discrete components. That includes the counters, driver circuits, and an array of LED.

There are a few inspiration pieces for [Phil]’s clock, starting with the Transistor Clock, a mains-powered clock that uses 194 transistors, 566 diodes, and exactly zero integrated circuits. Design patterns from a clock so beautiful it’s simply called The Clockare also seen, as is a Dekatron emulator from [VK2ZAY].

[Phil]’s creation has no PCB, and all the components are soldered onto tiny wires arranged into something resembling the clocks circuit. It’s a fantastic contraption, and while we’ll still have to give the design award…
