Time to Rise: Hacking Mornings with JavaScript, Raspberry Pi, and Creativity
summary
Builds a children’s alarm clock: a Raspberry Pi kiosk with touchscreen, USB speaker and a web admin UI, running Fastify + React + TypeScript and serving sounds from the backend because Chromium won’t autoplay. Configuration lives as a small JSON file on the filesystem, devices sync via local-only with WebSockets (no cloud access), bill of materials tops €100 so it’s not cost‑effective but it works, with a recurring sound failure that currently needs a weekly reboot. Hardware is a Raspberry Pi kiosk with Chromium.
