EucWorldPebble: your electric unicycle on a Pebble watch
29 March 2022 / Lefteris Iliadis / SomniusX

When you ride an electric unicycle, the phone stays in your pocket. Speed, battery and temperature still need a glance, though — and the handiest place for that glance is your wrist. That is what EucWorldPebble is for: a watchapp for Pebble watches that takes the figures from EUC World on Android and shows them on a big, easy-to-read gauge.

Both versions on real watches, next to EUC World’s screen at the same moment.
- Speed on an arc that changes colour as you near the limit you set.
- Battery, temperature, voltage and, depending on the version, the time or the current.
- Vibrations for alarms, with a different pattern for speed and current, so you know what is happening without looking.
- A horn on a button, a screen with ride time, distance and top speed, and km/h or mph.
There are two versions: 1.0tv with time, voltage and big digits, for every Pebble, and 1.0cv with current and voltage, for the Pebble Time. Both are ready as .pbw files under Releases, and load through the Pebble app with Rebble.

From the Pebble Time 2 to the round Time Round: one watchapp, five platforms.
The base is WheelLogPebble by JumpMaster, with contributions from Alexandros Kintis for voltage, current and the other models. Today’s change is a small one: the initial values now start at zero instead of the demo values used for testing.
How it works inside — the messages between watch and phone, the gauge that sweeps like a needle, and the font that keeps only the digits it needs — is on the EucWorldPebble page.
