Beginning Games Programming with Pygame Zero and Learn Electronics with Raspberry Pi (second edition).
Available from your favourite book store as softcover hardcopy or ebook.
Anyone with an outdoor track-powered railway knows the frustration of oxidation, and dead spots! 🚂⚡
I ripped up the track for a major garden railway refresh. Here is how I finally got outdoor track power working reliably:

Still work in progress, but now includes good functionality for controlling DCC locomotives and points using CBUS.
This year's Christmas Lights.
Controlled using 3 Raspberry Pi computers and 1 Raspberry Pi Pico.

I've upgraded a Disney Christmas Tree topper with a Raspberry Pi Pico.
Using a Pico W allowed me to add a web interface, and I used PWM to create an improved twinkle.
