MeshSat: connecting isolated networks

Prototype · field validation next Messages across mesh radio, satellite and mobile networks when connectivity is patchy or gone. I direct the software, architecture and hardware integration. Elli Zafeiridou Georgiadou assembles hardware and leads verification and QA; George advises on PR and marketing. Most code is AI-assisted, with human review and hardware testing. What works—and the limitsBridge software, Hub and phone clients are public. Radio and satellite paths have run on our prototype hardware; the transport documentation distinguishes hardware-tested paths from code-only and bench work. ...

opensymf — Open-Source SYMFONISK & Sonos Speaker Conversion

A whole-house project converting seven IKEA SYMFONISK and Sonos speakers from proprietary systems to Raspberry Pi-based open-source audio players — escaping vendor lock-in while keeping the original hardware intact. Source code & docs: github.com/papadopouloskyriakos/opensymf Why?

IKEA SYMFONISK speakers, being Sonos-based internally, face the same fate. Rather than accept planned obsolescence, this project replaces the proprietary brains while keeping the original power supplies, speaker drivers, buttons, and LEDs. ...
