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 :)
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 :)
Fully assembled, and running. I like it, it so much cleaner that the previous version.
I have some adjustment for the design to make it easier to build, but otherwise, I think this one is done !

New C library for Raspberry Pi Pico! This one displays procedural effects, animated sprites and text using WS2812B addressable RGB strips and matrices.
It allows multiple concurrent effects with independent framerates, masking, color inversion, global dimming, callback functions, and more.
Who needs a 6k display when you can do all of that on an 8x8 matrix?
