- During OpenAI Build Week, a community buildathon in Göppingen brought together 40+ people for an 11-hour day of building with OpenAI Codex.
- The event was intentionally non-competitive: no rankings, no winning pitch — just beginners, experienced developers, students, business leaders, children, and adults building together.
- One highlighted project was a child-friendly, smartphone-like device built around a Raspberry Pi, with restricted calling/media features and a parent companion app for access control and location checks.
- The post frames Codex as useful across microcontroller code, mobile apps, and broader project prototyping in a community setting.
