TOYTHON is a physical AI hackathon where people from the startup scene gather to implement ideas into actual prototypes and toys using AI Vibe Coding and development boards. Instead of just making apps, participants will create real, moving, and reactive objects in just 5 hours. No specialized knowledge, soldering, or embedded skills are required; simply connect cables to the connector and prepare for Vibe Coding. Participants will use NUCODE development boards (NU-40 DK, NU-87 DK) to create their own products with buttons, sensors, LEDs, and displays. The event is free and open to anyone in the startup scene, including CEOs, developers, planners, designers, and builders who are passionate about creating something fun. Participants can choose between two modes: EASY MODE for beginners to create reactive toys with boards, buttons, and apps, and MAKER MODE for experienced hardware makers to build commercial-grade products with sensors, output devices, and APIs. The event provides NUCODE development boards (for rent, can be kept by winning teams), OpenAI API credits and accounts, tutorials, mentoring, lunch, snacks, and additional credits for winning teams. Participants need to bring their own laptops and pre-install Arduino IDE + coding IDE accounts. Optional items include specific sensors (Qwiic modules like BME280, 9DoF IMU, ENS160, SGP40, or others from SparkFun Qwiic catalog) and pre-made cases (3D printed or acrylic cut).
