Granddaughter Clock

Posted on September 1, 2026 Tags: madeof:atoms, madeof:bits, craft:electronics, craft:paper Remember the Conference Talk Timeout Ring? Well, things may have escalated a bit. The first thing that happened is that I may have accidentally added more RGB LED rings, one for each size to an order of things that we actually needed, because they were cheap and potentially shiny (and I may have ideas that involve the big ones, but they are still just vague ideas). When they arrived, I played a bit with them to check that they were working, and one was used in a pinch as a light while soldering, and worked nicely. In the same order there was also a Raspberry Pico2 W and I decided to use it instead of the ESP32-C3-DevKit-Lipo I’ve used a lot lately because it has better support1 in CircuitPython. So, I have an RGB LED ring with a multiple of 12 LEDs and a microcontroller board with a lot of memory and wifi, what I’m going to do? a grandfather clock, obviously. Except our grandfathers didn’t…
