I've been adding a few things to my GurgleApps Word Clock. That's a 3D-printed desktop clock kit from GurgleApps based on the Pi Pico W running MicroPython inspired by the Biegert & Funk QLOCKTWO.

• Instructables: GurgleApps Word Clock Assembly With an Ambient Light Sensor - this shows how to add a phototransistor and resistor to measure light and automatically set display brightness, it also includes some notes on assembling the clock.
• Instructables: Adding a Touch Button to GurgleApps Word Clock Using RP2040/RP2350 Programmable IO (PIO) - shows how to add capacitive touch to Pi Pico 2 W (or any Pi Pico) with just a wire and no additional components using a derivative of the jtouch library.

I also had a go at some Halloween-themed pixel art with varying degrees of success and took a close look at what happens when you run the RGB LED 8x8 matrix (similar to Adafruit's NeoPixel ones) with a supply voltage below 5.0V.
