Signal Relay
A lightweight status dashboard for docked ships — broadcasts port assignments and departure windows.
Overview
Signal Relay started as a weekend experiment at berth seven: could a ship’s crew track port assignments without a corporate portal?
The answer was yes — with a static front end, a JSON feed from the dockmaster, and zero tracking scripts.
What it does
- Pulls assignment data from a plain JSON endpoint
- Renders status boards with semantic HTML
- Works offline once cached (service worker optional)
Lessons learned
Building for yourself first keeps the scope honest. The indie web mantra — own your content, own your stack — applied here literally: Markdown logs, hand-rolled CSS, no analytics.
