I use a #RaspberryPi #Pico2 as a debugger/programmer but fried a pin and broke it 😢. That's okay though! Tools and source are all #foss so updating to use new pins is possible and simple. Works like new again ✨

Testing sound on my custom built board. A bit quite but otherwise working nicely 🔉. I discovered #i2s is built into #micropython! Made for fast progress. The board is destined to become a handheld game console. #electronics #rp2350

Fresh off the workbench. My custom rp2350 board. It was a long journey with many mistakes. First time soldering 0402 and 80QFN parts. Board looks toasty as I redid the rp2350 chip 4 times!

Friendly reminder that the CFP for #DDDAdelaide 2026 is open. You don't need a finished deck or a polished pitch, just a rough idea and the willingness to give it a go. Some of our favourite speakers each year were people who almost didn't submit at all! dddadelaide.com

Learning new programming design patterns be like "All of you, get in there!". ECS + Command + Observer patterns are making an awesome combo though. Thinking about adding Behaviour Tree too. #gamedev #indiedev

Working on some basic #isometric #pixelart assets to test my hardware and display. Yes, that means the glitch broken display phase of my project is almost over ( I hope). #indiedev #gamedev

isometric pixel art of some basic shapes and textures.

Glitching so hard I couldn't add my #haiku to the screen: Data throught wires pixels speed to the display lapping at the screen #electronics #indiedev #gamedev #pixelart

Working on some goggle designs at the moment. This is version 2 which I'm very happy with, mostly because they work and don't look like a prop outta the Flintstones. Critical failing on both count of version 1 😂. #3dprinting #prusa #blender
