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!

Voting for #DDDAdelaide 2026 talks closes next week. If you haven't picked your favourites yet, now's a great time to get in there and have your say. The talks with the most votes get first pick of the agenda spots, so every single vote really counts. dddadelaide.com/voting

The ULX3S auto-labeling tool I've always wanted! Read from LPF Constraint file, generate and SVG image! Uses the @johnnewall.bsky.social pinout tool.

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

Hello world! #DDDAdelaide is back for 2026! Mark yourself as busy on the 21st of November! Time to start getting Call for Papers opening the 31st of July. And our new Early Bird tickets also open on the 31st of July. In the meantime, we have a slick new website out. Why not check it out?

You don't need expensive equipment or years of training to design your first chip. All you need is your laptop and a community to help you! Join our 2-day online workshop. July 13 & July 17, 5pm-7pm CEST. More info to follow 👀 Subscribe to our newsletter to get the latest updates. tinytapeout.com

Just pushing some pixels around today. #pixelart #isometric #indiedev #gamedev

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

It's a d-pad, with a twist! My current project is a handheld game console designed to showcase isometric content as a 'first class citizen'. #electronics #gamedev #indiedev #pixelart #isometric

Physical buttons are wired into the game and initial tests of the user interface are promising. Next: graphics to help explain this game console project. #electronics #indiedev

Pondering some scifi themed #isometric #pixelart characters . "Jacked-in gym bro" might make a good level boss? #indiedev

Touchscreens are nice but buttons are better! My game console is getting some buttons #electronics #gamedev #indiedev

Haiku devlog. Touchscreen is playing nice with a little robot friend. #isometric #pixelart #indiedev #electronics

Progress haiku on my handheld game console project. Finally - glitch free rendering. Makes me very happy. #isometric #pixelart #electronics #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

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

Because technical details make more sense as haiku. #electronics #gamedev #pixelart

Haiku at 20 frames per second. RPi Pico2 driving 320x480px display. #electronics #indiedev

Exploring colour palettes because <insert technical reasons here>. And they are pretty, so not complaining. #gamedev #indiedev #pixelart #electronics

More hardware tests and getting my isometric pixel art eye in. The display looks amazing. Way better than this pic suggests. #electronics #indiedev #pixelart

Glorious close up of pixels on my new display. Technical details sorted and visuals now looking good. #pixelart #isometric #electronics

Nearly, but not quite. Sending images from RPi pico2 micro controller to display. #electronics #rpi #pico #pixelart

Fresh and custom silicon day! 😍 This is a multicore riscv soc design based on the serv processor core. Based on GF180MCU PDK, and fabricated through wafer.space 🚀

Pixel art on a 3.5inch IPS display. Match made in heaven 💖 #pixelart #electronics

Man, PIO is so ridiculously OP.

whoo! game is live :D Sokoban, a turn based puzzle game. j0ono0.itch.io/scifi-sokoban #gamedev #indiegame #pixelart

Successfully testing the final level. Took some hours to convinced myself it was possible. My very small game of Sokoban is almost complete. #gamedev #indiedev #pixelart

Feeling like a responsible adult having published my first real maintenance update to Pinout, a Python package to help document electronics. Recently passed 400 stars on GitHub too! #electronics #Python

New main character has arrived. Forward progress on my little Sokoban project feels good. #gamedev #pixelart #scifi

Might have finished designing the hero of my little Sokoban game. Not perfect but total overkill for requirements. #pixelart #gamedev

Work in progress on some game graphics: Sci-fi themed Sokoban. I have some other ideas brewing too but aiming to publish a little demo game onto itch.io as a project milestone. #pixelart #gamedev #aseprite

KiCad version 10 is out today! Lots of features, lots of speed. We hope you like it. www.kicad.org/blog/2026/03...

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

Very happy to announce the winners of our demoscene competition! 🏆 We had some amazing entries - check out what can be done in just a few square microns of silicon! tinytapeout.com/competitions... Thanks again to our judges and participants! #silicon #demoscene #ASIC

I'm so atproto brained I keep thinking if enclose.horse had syncing with my account I'd 100% more do it daily if I could sync between my phone and computers

I made a game! Just a prototype but fully functional and ready to play for free thanks to @itchio.bsky.social 🎉 Pondering what the next steps might be to push this project along further. j0ono0.itch.io/theseus-and-...

Recycling some old pixel art to jump-start graphics for a little game I'm working on. Tech stack is #C, #SDL3, and #WASM all playing *very nice* together. #pixelart

ECS pattern, where have you been my whole life?! Currently playing around with some roguelike game programming in C. Might even finish something this time.

MicroPython v1.27 has been released! github.com/micropython/... It includes support for new micros, a whole swag of new features and bugfixes - and further improvements to automated testing, particularly by leveraging HIL. Congrats and thanks to the #MicroPython team!

My Zero to ASIC courses are the most recognized, highest-rated programs, and still the only ones that guarantee a tapeout! Start your journey toward holding a custom ASIC in the palm of your hand and save $150 with code Z2ABLACK25. ZeroToASICcourse.com

Good news! We open sourced the Pebble mobile app today -> github.com/coredevices/mobileapp Now all the software that powers your new Pebble is 100% open source. Read the full scoop on my blog ericmigi.com/blog/pebble-...

I was looking through my old projects and found this. I love how it looks and want to do more with this www.redblobgames.com/x/1638-voron...
