Understand this story
On October 29, 2026, OpenBMB showcased an ESP32-S3 cockpit-style attitude indicator project open-sourced by OpenBMB ambassador @emwstudio. The project uses MiniCPM5-2B to generate tower replies and VoxCPM2 to synthesize speech; the device sends push-to-talk audio over Wi-Fi to a Mac-side pipeline, where Qwen3-ASR performs local recognition, and the reply audio then streams back to the device speaker. The tower combines simulated flight data such as altitude, speed, heading, pitch and roll to point out inconsistencies between requests and instrument readings. The project is currently in an open-source showcase state, with no further progress disclosed.
