A bit over a decade ago I built a word clock - one of my first microcontroller projects. The project was fairly expensive: It uses a large stainless steel front panel (ca. 39cm x 39cm, laser cut) and a similar sized PCB. Over the years I had to resolder one or two of the RGB LEDs and replace a failed one, but other than that it’s still working as intended. ...
I‘ve always been fascinated by lights and all kinds of displays. Nixie tubes certainly are no exception. So I had to built my own Nixie clock as probably every EE does. ❗ Caution Nixie tubes require high voltages that might cause damage, serious injury or death. If you’re not authorized or qualified to work on such devices, don’t do it. I don’t take any responsibility for actions you take or the results of these actions. You do everything at your own risk. ...
