Just received my physical copy in the mail. It’s gorgeous!

After years of mental block, I've finally given niv the refresh I thought it deserved. More efficient UX and nicer UI. Forgot how fun Haskell is... and how deep the rabbit holes go! github.com/nmattia/niv

It’s never too late to try again 😁 I find MicroPython’s Unix port great for testing code and iterating fast!

Last year I prepared an article for @pagedout.bsky.social on how to display OLED graphics in the terminal to speed up embedded development. Was super happy they reached out and really like how the article came out! nmattia.com/posts/2026-0...

Nicolas Mattia – Terminal Graphics Protocol for fast embedded development

This article explains how the Terminal Graphics Protocol can be used to render embedded-style frame buffer graphics directly in a terminal for development and testing.

I’ve decided to buy a @prusa3d.com Core One+ using prusameters! I’ll be polishing up some projects and publishing them on Printables. The first one is this cute case for a #LoRa device. Like and download to fund my new printer! 😁 www.printables.com/model/163156...

You can now visualize how a color palette distributes across OKHsv, OKHsl, OKLCh and CIELab, and compare 6 distance metrics side by side. Zero dependencies, raw WebGL2. Took me 3 years to make something I wasn't too embarrassed to share 🙃 meodai.github.io/color-palett...

Cool repo! Link does not work for me as is though, I think you need to remove /settings 👍

SKAPA is the most challenging but also rewarding FE project I have undertaken (details 🔗👇)! I published the first version a year ago now. To celebrate the anniversary I've given it a fresh coat of paint, #a11y support and added some text for curious minds and crawlers alike. More to come soon!

I wrote niv years ago to make #Nix dependency management simpler — GitHub specific, built-in updaters. Talking about Nixtamal was fascinating. Different tradeoffs: no forge-specific shortcuts, fully scriptable updates, and a much more principled stance. I was impressed by how uncompromising it is!

My AirLab production unit just arrived! Very stoked! Designed and assembled by Networked Artifacts 10mn from where I live in Zurich, though it took a little detour to Texas before reaching my mailbox (: (Beta unit in the background looking jealous)

Found a postcard I had bought during covid and printed a SKADIS holder for it, then I knew I just had to update the cover image on Printables 😁 www.printables.com/model/113321...

Love it! Do you get any interference from surrounding boards or from the rack itself?

Before I spend a bunch of time reinventing this wheel for the hundredth time, does anyone know of a simple 4x4, nice!nano/ProMicro-based macropad PCB? If not, do you want one to exist?

Some of the 30 LEDs (1206) I soldered by hand for my latest obsession. Took me 10mn per LED for the first row; by the end I was managing about 1mn per LED!

Really love these old school DL1414t displays! The datasheet is convoluted — and in some places plain wrong — but when it finally works they're a delight to look at.

I ordered my first custom PCB. After some surgery on said PCB, I'm finally able to play snake how it was always meant to be played: on a 6x5 LED display, with 1 FPS. I still see it when I close my eyes.

I'm having the time of my life playing with Charlieplexed LEDs. With 4 pins, you can individually turn on each of 12 LEDs. Every unique of +/- combo turns on a different LED. 🤯 #ElectronicsFun #LEDMagic

I'm recreating a game (guess which one) for the Flipper Zero using a custom LED display. Sadly my display can only illuminate a single LED at once. But if it switches quickly enough... #FlipperZero

Some comments on your video say we’ll make up for the shortage with software optimization, let’s hope they’re right!

Uh I guess there are two "e"s in @jeffgeerling.com! Sorry and great watch BTW!

Nicolas Mattia @nmattia.bsky.social · 04/12/2025

RAM shortage: @raspberrypi.com is increasing their prices, and I just watched a video from @jeffgerling.com mentioning that others will follow suit — and it'll impact us all. I do all of my work on a 2021 MacBook Air with 8GB of memory and haven't experienced any sort of lag. What am I doing wrong?

Not again! Could anyone lend @github a ruler?

@pimoroni.com do you plan on making one with the Pico built-in like the 7.3”?

Trying to fit parts together for my next tiny device. The brains are an esp32-c3 and the star of the show is the DL1414t display by siemens, so old school!
