Good thing, matrix has 60 columns so I can make some test.
And I like it :)
Definitely needs a 61 columns to get a symmetry.

For the last months I spent my free time renovating a 100+ years old house.
But with today's heat that's not an option, so I'm back working on clocks :)
The plan is to apply what I learned building matrix (see this thread https://piaille.fr/@avernois/113391752318110644) to make a smaller version of my linear clocks (https://gitlab.com/avernois/clocks/-/tree/main/linear?ref_type=heads)

As I have way too much free time currently (I'm available if you'd like some help to tame a wild code base), I started a new clock project that is in the back of my mind since I reorganized my desk earlier this year.
The idea is to replace the word clock by a led matrix that could display time and fit on the shelf under the screen.

A case, and a piece of paper as a diffuser and looks so much better :)
I love it!
I still have some finishing touch, some features to code and a lot of cleaning :)

I designed the case, but it's too late to start the laser cutter. It'll wait tomorrow.
Instead, I quickly adapted the code I wrote for the prototype :)

So I added a connector, plugged it to a controller and nothing happened.
I had a moment of doubt, maybe the whole thing was faulty.
Then I look closely at the first led of the chain, and one of the pin wasn't correctly soldered.
I fixed it, plugged it again, and boom ! \o/

Only an hour to finish the placing of the leds.
I'm getting better :)
It's ready for the soldering on the hot plate.

90 min later, half of the leds are in place. That's 324.
And 324 leds to go :)

I did not realize when I posted that the video was that bad (it was late).
So, I made a (I think) better one.
I think I'm done with this prototype, I'll start working one the bigger version, maybe 11x50.

And we have clock ! \o/
This means I will most likely design the definitive pcb during the week end :)
@jasoncoon of Evil Genius Labs sent me his new 8x8x8 LED Cube. This is a volumetric display made of 512 WS2812 LEDs and a PixelBlaze inside a frosted acrylic box. It was a kit; I soldered and assembled it over the last two days. The PixelBlaze came with many preprogrammed effects, including these three.
It looks even better in person -- the camera oversaturated on the bright parts.

pcb arrived \o/
Damn that's compact.
I knew it (I designed them) but seeing them is something else. That's way smaller than everything I've made before.
So, it's soldering time !

This is quite compact pcb :)
Obivously freerouting did not successfully create a routing, but I can't really blame it.
I'll do it by hand tomorrow.

My plan is to use ws2812b led in 2020 package (2x2mm).
They are ridiculously small. They're going to stress my soldering skills :)
