I had some free time this sunday to solder the last two board I had, but not enough to test them.
So I did it this evening.
1 led in the wrong direction (on 1296 hand placed leds), and 2 with bad connections. All fix, and the board are running fine now \o/

I have no idea of what I'm gonna do with them. But I'll find out :)

#LedClock #ws2812b #esp8266

One is on the foreground, occupying 2/3 of the image, we see a close up of part of a led matrix ( around 17 columns of 11 rows of leds are visible). They are mostly lit in green, except the right columns which are light blue.
Behind, we see a part of another matrix (32 columns, 5 rows are visible). They are lit with a color gradient: red on the left, to green in the middle and blue on the right.

The two matrixes (60x11 leds each) sit on a black cutting mat.
They are both lit with a color gradient from red to yellow, green, cyan, blue, magenta and red again.

The two matrixes display time (20:36:20)

Humm, I guess I found why it's not working.

Can you? :)

#SpotTheDifference #ws2812b #LedClock #WrongDirection

Close up of a green pcb. About 20 leds are visible, they are align in a grid with a label above each one.
On each led, there is a green dot on its right.
Except one where the dot is on the left. Also, that led has burn mark :(

Hey Fedifriends ! What's the minimal css framework cool kids are using nowadays ?
I finally decided to write a UI for the configuration of my clocks :)

edit 2: maybe 'framework' is the wrong term. I'm looking for a css thing to make my page 'pretty' and consistent.
I can do (mostly) css, but I'm bad at pretty :)

edit: even if you don't consider yourself a "cool kid", you are to me and I'd like to hear the small css framework you use :)

#css #LedClock

I cut another grid on a better plywood and no more visible leaks \o/
There is still one, but in a place I'm not really using, so that's ok (for now).

I'll have to find a better way to make those kind of grid. Maybe 3d printing?

#LedMatrix #ws2812b #LedClock #LaserCut

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.

#LedMatrix #LedClock #esp8266 #ws2812b

And we have clock ! \o/

This means I will most likely design the definitive pcb during the week end :)

#LedMatrix #esp8266 #LedClock #ws2812b

Took some time this morning to sand the faces a little bit more, also I took better(?) pictures :)

#ws2812b #esp8266 #LedClock #LaserCutting

The fully assemble clocks displaying 13:35:31 with different colors.

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 !

#ws2812b #LedClock #LaserCutting

Cooking time :)

#pcb #LedClock

All layers (except front and back) are glued and clamped.
I'll let them cure for the night.
Tomorrow, sanding and final assembly before adding the electronic

#LaserCutting #LedClock

3 sets of laser cut plywood glued and clamped.

Two years ago I started a clock, called 'Stack'. The original thread on twitter https://x.com/avernois/status/1512472098849046535

I really like the way it represents times, but dislike the base (containing the pcb).
So regularly I come back to it to find a more satisfying solution.

Today, it such a day, and I think that, for once, I got something. 🧵

#LaserCutting #LedClock

All code/design/pcb is merged and can be found on my gitlab with the others : https://gitlab.com/avernois/clocks

Maybe I'll come back later to add some animation in the display.

But for now, I'll probably start to work on the next one ;)

#LedClock #LaserCut #ws2812b #gitlab

A slightly better picture.
#LedClock #ws2812b #LaserCut #esp8266

Same clock as previous post.
But now on a wood table in front of a white wall.
The clock is displaying 6:54:52

Seems to work fine ! \o/
No glitches in sight, I think I got it :)

I still have some work on the color pattern, but I'm starting to be happy with it.

#LedClock #ws2812b #LaserCut

A clock stand on a desk.
Behind we can see the bottom of a sceen.

The clock case is made of laser cut wood and displays time using 72 leds.
Leds are arranged in 12 groups. Each group has one in the middle and 5 around.
The 12 groups are arranged in a circle.

It currently displays 5:49:50

Here we go again !
Third iteration, hopefully the last one :)

#pcb #diy #ledClock

a green pcb.
The components are on it but not yet soldered holding in place with solder paste.
Among other technical writing one can read 'ws2812b & esp V2.1.3"

I think that clock reached its final form.
And I'm quite happy with it.

I still have some work on the color patterns and internal software. I'm not completely convinced on the way to encode time.

#LedClock #ws2812b #LaserCut #esp8266

Finally took some time to work on the color pattern. After few hours trying to be original I ended up reusing the pattern (and code) from 'linear' with a twist.
Internally, there are almost the same clock :)

edit: I uploaded the wrong video the first time. This should be better :)
