From the project
An open-hardware LED wristwatch that tells time with light. No mechanical hands, no display module — time is shown by 132 individually-addressable LEDs in concentric rings on a PCB dial, their light carried to the face through optical guides set into a branded mask.
Generated artifacts for the 37 mm dial PCB (156 LEDs, 13-pin Charlieplex).
