Building the Whisper Net: Off-Grid AI and the Cyber Pony Express
My ongoing experiment testing Meshtastic LoRa radios to build a resilient, grid-down communication layer that integrates directly with a local AI librarian.
Off-grid. Low power. Untraceable. This is not your typical network.
Over the last few weeks, I've been building what I call the Whisper Net—a community-powered, encrypted mesh network built on LoRa radios running Meshtastic. The goal is a resilient communication layer that survives without cell towers or centralized infrastructure.
Hardware Loadout
- Mobile Tactical Deck — a handheld T-Deck with GPS for urban exploration
- Backyard Oracle Node — a passive outdoor repeater
- Heltec v3 — floating node for testing and range experiments
The Cyber Pony Express
I owe the spark of this to a developer named Liz and the Cyber Pony Express—a radical experiment in using LoRa nodes as low-bandwidth delivery systems for zines, software, and localized knowledge. It's the Internet-in-a-Box.
Integrating the Ritual Stack
I'm taking it a step further by connecting the mesh to my Ritual Stack—a fully local AI system running on a Beelink SER5 Pro mini PC. It runs llama.cpp with Mistral-7B, whisper.cpp for voice transcription, and a custom persistent memory layer.
The dream: a local AI librarian in a grid-down scenario that receives learning packets via LoRa, indexes them locally, and speaks back when pinged. In a blackout, GPT can't help you. Sovereign tech is built, not bought.
