Just wanted to share a little project from a couple of months ago, Arduino Nano clone driving WS2801 LEDs with FastLED. I like these Nano clones from Aliexpress because they come with a more convenient USB micro port instead of the default USB mini port. Works for both programming and power if you don’t have too many LEDs
I made the hexagons small enough that I can use the string as is without having to splice in extensions.
The diffusers are just printer paper, lol. I made a template in Illustrator with foldable tabs. I used a little wood glue to keep the tabs adhered to the hexagons.
