Bringing my LED display to life with GPT-Live-1 and Codex
Blog post from OpenAI
A hobbyist transformed an airplane-tracking LED display into a voice-controlled home information wall using a Raspberry Pi, a 128 × 64 HUB75 RGB panel, an ESP32 controller running WLED-MM, Codex, and GPT-Live-1. Codex assisted with identifying hardware connections, configuring the panel, developing rendering software, troubleshooting, and moving the system from a Mac to an always-on Raspberry Pi. The resulting assistant, called Jack, supports conversational voice requests for weather, calendar events, subway arrivals, web research, images, messages, charts, countdowns, and custom scenes. GPT-Live-1 manages full-duplex voice interaction and delegations, while GPT-5.6 Luna handles tasks such as web searches, read-only calendar access, Wikimedia Commons image retrieval, and scene selection. A local renderer validates scene data, converts it into pixel frames, and sends them over the local network to the display, allowing the user to interrupt, clarify, or extend requests while research and rendering continue in the background.
