I built an 8-bit CPU simulator in Python from scratch▲72
I built a tiny 8-bit CPU simulator in Python to better understand how computers work at a low level. It visualizes registers, memory, and instructions in real-time, so you can actually see each operation as it happens. You can write simple assembly code and watch how the CPU executes it step by step. The project is mainly for learning and experimentation, but I’d love feedback or ideas for improvement.

Interactive pinout for the Raspberry Pi Pico 2▲150
I've been trying to make accessible and beautiful GPIO pinouts since I started one for the Raspberry Pi in 2013 [1]. I've since given the Raspberry Pi Pico [2] and Pico 2 [3] microcontrollers the same treatment when they launched. Recently I've updated these with a new "Upside-down" view to complement the rear view, giving a pinout in the right orientation to match your project. The Pico sites are all hand-coded single HTML pages with supporting CSS and minimal JS. They are set up to optionally install as a "Desktop" web app. They also degrade into a somewhat usable table in lieu of CSS and…
