Description

This project converts an unused smartphone into a dedicated weather informer display. It uses a single self-contained HTML/JavaScript file to fetch weather data (via the Yandex API) and display time, date, temperature, and additional weather indicators in full-screen mode. The setup requires minimal hardware changes — just a phone, constant power, and a browser. Full russian description here.
