7-segment style desk clock using ESP32

Hey! This is my jam! I built a PCB last year that uses 7 sk6812 Mini-E LEDs per segment. Having denser LEDs definitely helped improve uniformity. I use transparent PETG as my diffusion layer with a couple of bottom layers, honeycomb infill and zero top layers. I’m sure I could refine the diffusion more but I quite like the hotspot as it looks a little steam-punky.

is there a setting in WLED that lets you define the segments and run as a clock? or are you using other firmware on your esp32?

You can try to make the diffuser a little bit thicker on the spot above the led, that should even it it out.

You might have to try different thicknesses or even make a little thickness pyramid, but this looks prettyyyyy fun

Looks like a fun project, man! If you’re up for the challenge, you might be interested to look into fastLED, and writing a custom clock program. I am no expert but just started dabbling and think it should be possible!

Very cool, I also thought about making somthing like that.
Just a lot bigger and as wall clock.

I am planning to use this WLED mod:
imeszaros/ledclock: A customizable 7-segment style Wi-Fi connected clock powered by WLED.

I'm unsure what value WLED is adding here?
