An open-source gateway that bridges Meshtastic LoRa mesh networks to the Iridium satellite constellation via Short Burst Data (SBD). One gateway device provides satellite backhaul for an unlimited number of mesh nodes — instead of paying per device like Garmin and ACR charge. Overview Aspect Details Function Bidirectional Meshtastic ↔ Iridium SBD bridge Hardware Raspberry Pi 5, Lilygo T-Echo, RockBLOCK 9603 Backend Go 1.24 (chi router, SQLite) Frontend Vue.js 3 (SSE, Leaflet maps) Deployment Docker multi-arch (ARM64 + x86_64) License GPLv3 Repository github.com/cubeos-app/meshsat Why MeshSat Consumer satellite communicators like Garmin inReach and ACR Bivy Stick MESH charge per person or cap at 12 devices. A 20-person expedition pays €300/month for individual Garmin subscriptions. MeshSat replaces that with a single €15/month satellite link shared across the entire mesh network. ...

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? Sonos ended support for older speakers, stranding them on a frozen S1 platform with no future updates or integration with newer devices. 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. ...
