A review of Meshtastic, a cheap, encrypted, offgrid communicator using T-Beam devices. The review includes both positive and negative aspects of the project.
T-Beam Meshtastic is a wireless module with ESP32, LoRa, GPS, WiFi, and Bluetooth capabilities. It features a 0.96-inch OLED display and supports various frequency bands including 433/868/915/923Mhz.
Nick Farrow has created MeshBoard, a text-based bulletin board system inspired by the BBSes of the 1970s and 1980s, running on a Raspberry Pi using the Meshtastic mesh network. The project allows for menu navigation and interactive games like Tic Tac Toe and an Escape Room, with no internet required. It leverages Python to create a modular and easily extensible platform, with plans to expand features such as file transfer over the Meshtastic network.
MeshCom is an open-source project for exchanging text messages, positions, and data using low-power, low-cost LoRa radio modules. It aims to create off-grid, mesh network communication systems.
