🔥 Google Sign-In just landed on @juno.build About time I gave devs a familiar UX for signing in 😅 - really excited to see where this one goes! juno.build/blog/google-...

I polished and published a #MicroPython experiment for emulating OLED displays in the terminal. Uses kitty's Terminal Graphics Protocol. Feedback welcome!

From 0 to LOREM in 10 seconds! Flashing the @raspberrypi.com rp2040 is just too easy.

As a #Halloween treat to ourselves, my partner and I wrote a Choose-your-own-adventure story and flashed it to a @pimoroni.com Tiny 2040. 👻 That way, we can play wherever we want, on any device. Here in the 🍎 Notes app.

Last year I didn't wrap up my single-key "ghostwriter" keyboard in time for #Halloween. This year I should have plenty of time... *checks date* nevermind

I'm pretending I have too much free time and have decided to resurrect the Voron 💀

I'm writing a snake game for the #FlipperZero. Am pretty happy with the app icon :) 🐍 #DIYGame #Rust

Version 0.0.6 of quad-shader is out on npm! This only includes npm-related metadata fixes, thanks to @daviddalbusco.com.

I've recently added more code samples to my shader animation library. Reach out if you are interested in specific examples! #CreativeCoding #Shaders #GenerativeArt

i wrote about atproto and why it matters

Here's your gentle nudge from ESD-1 — the Emotional Support Device — reminding you that your outie is kind-hearted. #selflove #severance #dieterrams

Evening light diffracted onto the @prusa3d.com looks surreal

Did you know your MacBook has a sensor that knows the exact angle of the screen hinge? It’s not exposed as a public API, but I figured out a way to read it and make it sound like an old wooden door.

Getting ready for day 2 of NixCon

Experimenting with Charlieplexing: 1 Pi Pico, 4 pins, 12 LEDs

Experimenting with a new blog post format I'm calling "build logs". Short-ish articles recapping small weekend builds. nmattia.com/posts/2025-0...

Thank you @prusa3d.com for the shout out!!

I don't have a problem! I can stop buying microcontrollers whenever I want!

I bought a B&W label printer from a friend (for labeling boxes) and it turns out to be much more fun than expected

Oh that feeling when good tools work together! Using kitty's graphics protocol and MicroPython's unix port + framebufs to debug SSD1306 oled code in my terminal. gist.github.com/nmattia/7a00...

Getting really happy with where this is going

Playing with the design for a battery powered tiny computer, trying to shrink the case as much as possible

I'm making a puzzle game where you manipulate light! #gamedev #indiedev Wishlist: store.steampowered.com/app/3081690/...

Note to — adventurous — embedded Pythonistas (MicroPython and @circuitpython.org): I'm looking for feedback on an HTTP server library I'm working on. The repo is here: github.com/nmattia/uht Still a work in progress, but it's got install instructions and docs! nmattia.github.io/uht/uht.html

Needed a small case for traveling with my @raspberrypi.com Pico 2W, model is on Printables www.printables.com/model/136870...

Oh yeah! DIY filament dryer, hacked from a food dehydrator. Precise, smart and compatible with @home-assistant.io (Pico W aboard)!

Used to really like Onshape, now I love it! (designing custom bins for my Allit EuroPlus storage cases) #cad #3dprinting

Having fun with my latest gadget

Quick message to the Rust and Nix lovers out there! Did some long-overdue maintenance on Naersk👇, including better support for modern Cargo lockfiles. I did however nuke support for old Nix & nixpkgs versions, let me know if you run into issues :) github.com/nix-communit... #Nix #NixOS #rustlang

There’s no escape

I love it when I remember that #Nix has a `--max-jobs` option. My 2019 Intel MacBook doesn’t.

Captive portals are the worst part of hotels and airports. But they might be just great for configuring a Pi Pico! I’ve been looking for a way to set up a @pimoroni.com Inky Frame without connecting it to a computer - beyond the initial UF2 install (no thonny, mpremote, etc). More soon :)

Andor really should have had more than 2 seasons. The could have called them Andor, Xor, Notor, Nand, and Xnor.

Working on two Raspberry Pi Pico projects — one in @rust-lang.org, the other in @python.org (MicroPython). The difference between the languages is pretty wild. One has zero-cost abstractions, strong static typing, pattern matching, and modern syntax. The other has... whatever the f*ck this is.

Just plugged RampenSau into p5.js — effortless color ramp magic 🎨🐗 Generate smooth HSL gradients with zero fuss. Perfect for generative sketches: editor.p5js.org/meodai/sketc... #creativecoding #p5js #colors #genart

Fancy button, adaptation of previous work by @meodai.bsky.social codepen.io/nmattia/full...

New post out! (tutorial, technically) nmattia.com/posts/2025-0... #WebGL #GLSL #Shaders #CreativeCoding #JavaScript #CodeArt #TechWriting #genart

Hey @mary.my.id ! I was looking at your component for BlueSky embeds and trying to do something similar (client side). If I call windows.bluesky.scan() manually, how likely are things to break in one, three or 12 months? github.com/nmattia/nmat...

3KB ain’t much, but it’s honest work 😉

TFW you decide to write a “quick blog post” and 15 hours in there’s still no end in sight. On the plus side I have fallen in love with @excalidraw.com

Overhauled the microsite for my #WebGL helper library quad-shader, feedback much appreciated! nmattia.github.io/quad-shader/

Sunday afternoon fun with WebGL and “rampensau” by @meodai.bsky.social #genart #WebGL

Couple shots from LJ #slovenia

Fell in love with iPhone's "Hearing Test" animation, just had to try and recreate it #generative #art

Computer graphics is amazing, could watch this all day #art

Shaders don't have typos but happy accidents #art #creativecoding #shaders

New @home-assistant.io and ollama setup

Two hours to recover 10 pixels? Worth it. (Changing the edge detection to use the Sobel operator for cleaner diagonals)

New SKAPA clip design (right) for support-free printing → skapa.build

Weekend project: falling in love with ESPHome from @home-assistant.io. (Actual project: making an analog control panel for my printers. Sound on for satisfying switch sounds.)
