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.
