Off-grid mesh node with local AI TAK integration and Bitcoin Cashu payments built on Meshtastic

Open source gateway bridging Meshtastic LoRa, Iridium satellite, cellular SMS, APRS and TAK over a Reticulum routing layer. Keeps people connected when the network is not. Runs on a Raspberry Pi.

connect like it's 1984 - neo146 provides a minimal (and experimental!) information gateway that serves as an emergency network connection method inspired by dial-up, allowing you to access content via certain protocols like SMS.

A curated list of open protocols, applications, hardware, and resources for communication during internet shutdowns, disasters, intermittent connectivity, censorship and off-grid operation.
