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 πŸ™ƒ

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

SKAPA is the most challenging but also rewarding FE project I have undertaken (details πŸ”—πŸ‘‡)! 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 β€” 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)

For 2026 I’m treating myself to a new programming paradigm with the Icepi Zero

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!

My friend’s programming book arrived just in time for some cosy holiday reading!

Really love these old school DL1414t displays!

The datasheet is convoluted β€” and in some places plain wrong β€”Β 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.

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...

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

RAM shortage: @raspberrypi.com is increasing their prices, and I just watched a video from @jeffgerling.com mentioning that others will follow suit β€”Β 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?
