Context

Client Context

A non-profit organization ran the 'Clock of Change' project - a physical device with a 16-segment display showing messages to an international audience.

The control surface needed to be simple: manage content through a WebApp, edit multilingual messages, configure WiFi. But everything had to run on the Raspberry Pi 3b+ that already drives the display.

Challenge

Build a WebApp that runs on a Raspberry Pi 3b+ with minimal RAM and CPU - and that handles administration, multilingual content, and display control through a single interface.

Solution

Lightweight local web architecture - deliberately without unnecessary build steps or complex infrastructure. Data storage runs locally, with no separate process and no network overhead.

Admin and user roles, scrolling-text management for the display, WiFi configuration, and 4-language support (DE, EN, FR, ES) - all in one intuitive interface.

Result

Functional WebApp running on a 5+ year-old Raspberry Pi 3b+ with minimal resource use. The non-profit manages content independently, no developer required.
