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…

A while back I wrote a CHIP-8 emulator (which is considered the Hello, World! of emulators and is more accurately a virtual machine since historically CHIP-8 was an interpreted language running on top of the COSMAC VIP to make game programming easier). But a few months ago I got really interested in embedded software, so decided it would be neat to port my emulator to a STM32 MCU and design a console around it as a learning experience, since CHIP-8 never existed as a physical system. I didn't know much about embedded software when I began, and even less about electronics, but I managed to…

Hey HN, Over the past ~1.5 years, I built an open-source FPGA retro emulation handheld that can play Game Boy, Game Boy Color, and Game Boy Advance cartridges. To my knowledge, there isn't an existing open-source FPGA emulator that can play physical cartridges like this. One of my main goals was to do all of the pieces myself, and be able to understand every component of it, so I designed my own PCB, wrote the firmware, wrote a Game Boy and Game Boy Advance emulator for the FPGA (using the Chisel HDL), and designed a 3D-printed case. I detailed the design and development process in the…

I recently dug my Nintendo GameCube out of storage to revisit the first Animal Crossing game. Things were mostly as I remembered, but the game's heavy reliance on a clunky on-screen keyboard quickly wore my patience thin. Unwilling to accept this subpar experience, I did what any rational person would do and ordered a rare, Japan-exclusive, keyboard/controller hybrid on eBay, then used a Raspberry Pi Pico to 1. listen for keypresses and 2. send simulated controller events to the GameCube, automating typing in Animal Crossing at a Tool-Assisted Speedrun level. Of course, this oddball…

Just a toy, showing how easy it is to leverage built-in Emacs features (most notably Artist mode, which provides a set of functions for creating ASCII-art vector graphics) and things like trigonometric functions and timers to create something nice.
