Texting When the Grid Isn't Available
Off-Grid Mesh Radio Workshop
Learn to build and deploy LoRa mesh radio networks that work without internet or cell service. These low-power devices communicate over miles of range, automatically relaying messages through the network to extend coverage across farms, forests, and neighborhoods.
What You'll Learn
- Hardware setup - Working with affordable microcontrollers like ESP32 and Raspberry Pi Pico
- Firmware flashing - Installing and updating mesh radio software on your devices
- Network configuration - Setting up channels, encryption, and multi-device networks
- Sensor integration - Connecting environmental sensors and sending data over the mesh
- Custom functionality - Building modules for your specific monitoring needs
Applications
- Farm monitoring - Track soil moisture, weather stations, and livestock across large properties without cellular coverage
- Grid-down communications - Maintain text messaging and location sharing when power and internet are unavailable
- Remote sensing - Monitor water levels, temperature, and other conditions in areas without infrastructure
- Asset tracking - Keep tabs on equipment, vehicles, or animals across wide areas
- Community networks - Build neighborhood communication systems independent of commercial infrastructure
How It Works
LoRa (Long Range) radio technology enables communication over several miles using minimal power. When multiple devices form a mesh network, messages automatically hop from node to node, extending range far beyond what a single radio could achieve. Each device can act as both an endpoint and a relay.
Workshop Details
Perfect for farmers, homesteaders, emergency preparedness enthusiasts, and anyone interested in resilient communications. No prior radio or electronics experience necessary - we'll start from the basics and have you sending messages by the end of the session.
