Hex Matrix Clock Is Spellbinding

Just when we think we’ve seen all possible combinations of 3D printing, microcontrollers, and pretty blinkenlights coming together to form DIY clocks, [Mukesh_Sankhla] goes and builds this geometric beauty. It’s kaleidoscopic, it’s mosaic, and it sorta resembles stained glass, but is way cheaper and easier.

The crucial part of the print does two jobs — it combines a plate full of holes for a string of addressable RGB LEDs with the light-dividing walls that turn the LEDs into triangular pixels. [Mukesh] designed digits for a clock that each use ten triangles. You’d need an ESP8266 to run the clock code, or if you’d rather sit and admire the rainbow light show unabated by the passing of time, just use an Arduino Uno or something similar.

Most of the aesthetic magic here is in the printed pieces and the FastLED library. It has a bunch of really cool animations baked in that look great with this design. Check out the demo video after the break. The audio is really quiet until the very end of the video, so be warned. In our opinion, the audio isn’t necessary to follow along with the build.

The humble clock takes many lovely forms around here, including pop art.

    1. Pick up a curb treasure fridge… not only do you get a stable temperature for your 3D printer to work in, it’s probably fire and according to Indiana Jones, nuke proof as well.

  1. I was wondering why he’d designed the enclosure to be so huge… then the LEDs with all that wire went in. I guess those strings must be cheap, but I’d have spent the time on desoldering and trimming the cables.
    It is quite a pretty thing, I think I’ll make one.

    1. I used the WS2811 LEDs,each LED is covered with resin we cannot desolder the LEDs. Instead we can use WS2812b LED stip. For that you have to design the Matrix but the code will work fine.
