CODEX


A personal project currently in the works at the intersection of industrial design, resilience, and generative AI. Codex is an all-metal, Faraday-sealed terminal housing a local LLM and a massive offline database of technical survival schematics. It is a tool designed not just to help you survive, but to provide the technical competence required to thrive in a grid-independent world.

In other words, it’s offline Chat GPT for the end of the world.

The Details


Status: In Prototyping (Hardware & Software Architecture)

The Concept: Codex is a "Library of Alexandria" for the end of the world. It provides immediate, offline access to the sum of human survival knowledge without reliance on GPS, cellular, or cloud infrastructure. It’s a grid-independent system designed for the post-connectivity era.

The Hardware: At its core lies a Google Pixel 8 Pro compute unit, stripped of tracking telemetry and re-housed within a custom 6061-T6 aluminum chassis. The device features a proprietary "Flip-Flop" architecture with N52 magnetic sealing, creating a verified Faraday Cage that physically isolates the device from RF signals when closed.

The Intelligence: Unlike standard devices, Codex runs a locally hosted, uncensored Large Language Model (Nous Hermes 2 Pro - Llama-3 8B). This AI does not rely on the internet. Instead, it utilizes a RAG (Retrieval-Augmented Generation) framework to index and synthesize a massive onboard repository:
  • The complete US Army Field Manual library.
  • Surgical and emergency medical databases.
  • OpenStreetMap vector data.
  • The entirety of Wikipedia (compressed text).
