PCB Watch

Under the guidance of Prof. Arik Slepyan, I built this PCB watch as a project for the class EN.520.299. Powered by an ATtiny 414, it uses 12 SMD LEDs to indicate the time and also has a magnetometer so you can use it as a compass. Its three auxiliary LEDs, located under the 12 O'clock position, display AM/PM, daylight savings status, and compass mode status. The board was designed in KiCAD.

Watch on my wrist next to a Casio watch — The finished watch on my wrist next to my dependable Casio

Lessons learned/things I would change

Smaller lug-to-lug width. I didn't anticipate the strap sticking so far out beyond the attachement loop.
Thinner battery holder. The watch sticks off my wrist an uncomfortable amount
