Some friends and i exhibited different projects at Makerfaire Hannover 2023 (Germany). Part of the package was a goodie bag with a DIY kit for a word clock.

This word clock is just a Wemos D1 mini, some WS2812 and a paper box to put it in. What is missing? ... Right, the software. You can also buy the kit from "build-yours.de" with a pre programmed MCU, but you can't get the firmware.

So i wrote my own firmware, just out of spite. It is horrible spaghetti code and the fancy app is missing, but at least you can get it here.

Build Instructions

1

Get a kit.

You get a piece of wood with the schematic engaved into it. The Electronics and wires as well as a box, dividers to prevent crosstalk between the leds and two overlays for the wordclock. The firmware only works for the word clock, so that decision is easy.
2

Glue and solder everything together.

Glue the led stripes to the wood. Make sure the led stripes are oriented in a way so that they snake up the board. Do not change their position.

The Wemos D1 is glued with a big splasch of hotglue to the wood.

Solder the led stripes together:

VDD -> VDD

GND -> GND

Dout -> Din

After that solder the begining of the led stripe to the Wemos D1:

VDD -> VDD

GND -> GND

D4 (Wemos D1) -> Din (led stripe)
3

Put it in the box.
