#ws2812b — Public Fediverse posts

A year later, and I finally cleaned the files, code, and history. *matrix* is officially done \o/.
All files (code, pcb & case) can be found here: https://gitlab.com/avernois/clocks/-/tree/main/matrix?ref_type=heads

Testing something else (reusing the small matrix I made as proof of concept for the bigger one).
It's nothing original, but it looks nice. ;)

And it will probably be better with thinner acrylic sheet and better led placement.
I guess I have to make a pcb and order some 2mm acrylic sheets :)

Finally found some time to bring my #NeoPixel Heart PCBs into a usable state and add some documentation. The #sourcecode is hosted on @Codeberg at https://codeberg.org/rommudoh/NoisyMcHeart and works for both variants (big and small).
I think I'll publish the #KiCad files soon, too.
Thanks to #platformio I can use the same code for both hardware variants.

Inspired by my last #WS2812B #PCB, I decided to do a smaller version and try to add a USB C connector. I'm very pleased how it turned out. The LEDs are not as close to each other as last time, but I still used my hot plate to solder them. And hot air for the back side.
Again, manufactured by @aislerhq and designed using @kicad

Here are the boards! I soldered a first one by hand, but the #WS2812B #LEDs are very close to each other. So some have burn marks. Hot air is no option, it would burn them up. So, I bought a hot plate and tried again. It's so much faster and easier! And it worked directly after #soldering.
I only need better solder paste, this one was difficult to clean.

Since it'll take some time for the PCBs to arrive, I decided to make a #prototype on #perfboard. It works fine, and I can test my programs using it. Turns out an #ATtiny814 is good enough for the task.
The #WS2812B #SMD #LEDs are very bright, though, and reducing brightness also reduces the possible color range.
The different color shadings are not very distinguishable, yet. I might have to adjust the color palette.

Новогодняя гирлянда на BluePill

Близится Новый год, а гирлянда на ёлку не готова. В комоде уложена старая, её использовали уже пять раз и хочется чего-то нового. Предлагаю сделать свою, на популярной плате STM32 BluePIll в связке с адресными светодиодами. Это история с открытым концом. Если читателю идея покажется интересной, будет прошивка на git с реализацией интересных задумок; в противном случае, придётся купить готовую на маркетплейсе. Но мы же этого не допустим? Предложить идею

Learn here how to install the wLED binary, which means flashing your ESP32 microcontroller.

Make sure your power source is constant, which means use a uninterruptible power supply, UPS, at least while you are flashing!

Please do not brick your ESP32

This is een important word of warning from the wLED Creator

New setups should use the ESP32 not the dated ESP8266 because that micro controller reaches end of life / end of support soon. The ESP32 also has Bluetooth which The ESP8266 lacks.

Heed his Warning

Now you can learn how to do the wLED control on the Raspberry Pi5

So first start with my previous post then come to this one. Of course you understand why this logic is used; first learn to crawl then Sprint.

My SBC of choice is the Raspberry Pi5
I want to control wLED with it!

So i dug further and found this site, where you learn from scratch how to start with the ESP8266

Today I learned about an incredible project for the ESP32 project WLED! ✨

It's an implementation of a ESP32/ESP8266 webserver to control NeoPixel LEDs

Read all about it on the website.

It’s time for new projects. Like this small version of the Space Clock as an LED matrix.
It opens up even more possibilities.

Slightly better (I think) picture :)

It'll land on the shop (https://shop.crafting-labs.fr/en) soon.

I made the missing cuts yesterday and finished the assembly today.
Circles 1/32 is up and running.

I still need to figure out the correct lighting to take better pictures, but that'll wait tomorrow.

#LedClock #esp8266 #ws2812b

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)

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 :)

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?

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.
