John (j0ono0) @johnnewall.bsky.social · 01/10/2026I made some labels to remind future me of the changes pins. 100% chance I'll forget. I should mark the broken pin too somehow 🤔 000
John (j0ono0) @johnnewall.bsky.social · 01/10/2026 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 ✨ 100
John (j0ono0) @johnnewall.bsky.social · 30/09/2026Testing 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 021
John (j0ono0) @johnnewall.bsky.social · 24/09/2026Fresh 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! 010

Reposted by John (j0ono0)DDD Adelaide @dddadelaide.bsky.social · 10/08/2026Friendly 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 032
Reposted by John (j0ono0)DDD Adelaide @dddadelaide.bsky.social · 26/07/2026Hello 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.

John (j0ono0) @johnnewall.bsky.social · 27/06/2026Surprise 'joys' of hot weather living in a house not designed for hot weather? 000
John (j0ono0) @johnnewall.bsky.social · 24/06/2026Learning 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 082
John (j0ono0) @johnnewall.bsky.social · 20/06/2026Early testing is positive too, feels natural moving on the diagonals. Fingers crossed it translates well into a polished prototype. 000
John (j0ono0) @johnnewall.bsky.social · 19/06/2026Lots to learn, but I think it'll be an interesting journey. 000
John (j0ono0) @johnnewall.bsky.social · 19/06/2026Thanks!! Yes, at least a few games planned. Partly for testing and showing off hardware, but mostly because it'll be fun. 110
John (j0ono0) @johnnewall.bsky.social · 19/06/2026Yes! The genre is front of mind for me. I've been looking at Syndicate screenshots too. 110
John (j0ono0) @johnnewall.bsky.social · 19/06/2026Coding in C and started from scratch (including hardware drivers) so I have a fair idea of where my clock cycles go. Using both cores was the 'killer move' though. 020
John (j0ono0) @johnnewall.bsky.social · 19/06/2026The Pico 2 has been great to work with. Seems capable so far too. I have one core running the display and the other game logic. 120
John (j0ono0) @johnnewall.bsky.social · 19/06/2026It'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 7796
John (j0ono0) @johnnewall.bsky.social · 18/06/2026Physical 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 062
John (j0ono0) @johnnewall.bsky.social · 16/06/2026hahaha! love it :D A blend of fashion over industrial backdrop is actually where my head is at so on target with this imagery. 010
John (j0ono0) @johnnewall.bsky.social · 16/06/2026Pondering some scifi themed #isometric #pixelart characters . "Jacked-in gym bro" might make a good level boss? #indiedev 1213
John (j0ono0) @johnnewall.bsky.social · 12/06/2026Touchscreens are nice but buttons are better! My game console is getting some buttons #electronics #gamedev #indiedev 092
John (j0ono0) @johnnewall.bsky.social · 09/06/2026Haiku devlog. Touchscreen is playing nice with a little robot friend. #isometric #pixelart #indiedev #electronics 171
John (j0ono0) @johnnewall.bsky.social · 05/06/2026Progress haiku on my handheld game console project. Finally - glitch free rendering. Makes me very happy. #isometric #pixelart #electronics #gamedev #indiedev 0122
John (j0ono0) @johnnewall.bsky.social · 02/06/2026Working 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 0205
John (j0ono0) @johnnewall.bsky.social · 29/05/2026Glitching 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 0152
John (j0ono0) @johnnewall.bsky.social · 22/05/2026Because technical details make more sense as haiku. #electronics #gamedev #pixelart 071
John (j0ono0) @johnnewall.bsky.social · 19/05/2026Haiku at 20 frames per second. RPi Pico2 driving 320x480px display. #electronics #indiedev 060
John (j0ono0) @johnnewall.bsky.social · 16/05/2026Glitches and bugs continue 😭 Turns out I can't count high enough to address an entire 320x480 screen with a 16bit integer. Obvious once i pointed it out to myself 🙃 010
John (j0ono0) @johnnewall.bsky.social · 15/05/2026A gallery of samples from my glitch-tastic day as I iron out display bugs. #electronics #indiedev #gamedev #pixelart 182
John (j0ono0) @johnnewall.bsky.social · 14/05/2026Exploring colour palettes because <insert technical reasons here>. And they are pretty, so not complaining. #gamedev #indiedev #pixelart #electronics 0152
John (j0ono0) @johnnewall.bsky.social · 12/05/2026Sure is! Pico2w, talking to the display over SPI using PIO. The display is 480x320 pixels. I'm yet to measure refresh speed but it looks fast! 110
John (j0ono0) @johnnewall.bsky.social · 12/05/2026More hardware tests and getting my isometric pixel art eye in. The display looks amazing. Way better than this pic suggests. #electronics #indiedev #pixelart 1140
John (j0ono0) @johnnewall.bsky.social · 09/05/2026Glorious close up of pixels on my new display. Technical details sorted and visuals now looking good. #pixelart #isometric #electronics 050
John (j0ono0) @johnnewall.bsky.social · 08/05/2026Nearly, but not quite. Sending images from RPi pico2 micro controller to display. #electronics #rpi #pico #pixelart 070

John (j0ono0) @johnnewall.bsky.social · 23/04/2026Successfully 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 0102
John (j0ono0) @johnnewall.bsky.social · 21/04/2026Feeling 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 030
John (j0ono0) @johnnewall.bsky.social · 09/04/2026New main character has arrived. Forward progress on my little Sokoban project feels good. #gamedev #pixelart #scifi 1102
John (j0ono0) @johnnewall.bsky.social · 02/04/2026Might have finished designing the hero of my little Sokoban game. Not perfect but total overkill for requirements. #pixelart #gamedev 1122
John (j0ono0) @johnnewall.bsky.social · 24/03/2026Work 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 0122

John (j0ono0) @johnnewall.bsky.social · 14/03/2026Working 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 000
