Fully Assembled Binary Clock – WS2812 LEDs, Microcontroller-Driven

Description

A clock that makes you work for the time. Each WS2812 LED represents a bit, either on or off. Read the pattern, do the binary math, know what time it is. Runs on an ATmega328PB with a DS1307 real-time clock keeping accurate time even when unplugged.

Fully built and tested. Just power it up and set the time. No soldering, no kit assembly, just a weird little clock that’s fun to read once you get the hang of it.
