Taz: a voice-reactive pocket pet — build photo from the creator’s source
covacut · build photo

What the hardware does

An ESP32 drives a small OLED face and connects a microphone and speaker so a physical pet can listen and react with animations.

How the agent helped

The creator credits Codex with implementing Wi-Fi setup and troubleshooting the firmware's connectivity, audio and conversational behavior. Task execution is an ambition, not a demonstrated feature.

Before you build

Wired prototype with separate microphone, amplifier and speaker. Performing tasks is future work, not demonstrated functionality.
