The Nothing Phone has 169 LEDs on its back. I wrote an app that puts a clock, a spirit level, a timer or a timetable on them. The modules above run live.

What is inside

  1. 01

    27 modules on 169 LEDs

    Clock, spirit level, compass, metronome, tuner, school timetable and more. All readable on a 13 × 13 matrix.

  2. 02

    Timetable from ŠkolaOnline

    The back of the phone shows whether it is a lesson, a break or free time.

  3. 03

    Builds anywhere

    The vendor SDK is not in the repo. The app finds the interface at runtime and falls back otherwise, so the project builds on any machine.
