Building a Printed Circuit Board from a Blank Canvas with GPT-6 Astra and Codex

Justin Lin, a research team member at OpenAI, walks through a project exploring how GPT-6 Astra can design a printed circuit board and how voice interaction with Codex can be built into a physical interface. He shares the process from a blank board layout to a fabricated prototype, along with the iterations involved in working with a manufacturer.

■ Project Overview
- Background and goals of the Astra project combining computing and physical engineering capabilities
- Designing a printed circuit board from an empty layout, including supplying plans and multiple design attempts
- The multi-round manufacturing process and parallel design prototypes
- Iterating on different structural versions of the board
- Creating an on-screen Codex interface with a button to press and speak to
- Interacting with Codex by voice, including checking active agents
- Views on how interacting with physical devices expands what is possible

Recommended for viewers interested in how large language models are applied to hardware design and voice-driven agent interfaces. Watching will give you a sense of the workflow, the trial-and-error involved, and the direction this kind of device interaction is heading.
