Give a Bluetooth speaker a character — build photo from the creator’s source

What the hardware does

A repurposed speakerphone supplies the microphone and speaker for a character running through an Android app and private backend. The character asks before retaining memories.

How the agent helped

The creator describes Codex as an engineering partner for the app and backend implementation. The documented work is not custom speaker firmware; firmware exploration remains future work.

Before you build

Custom Android app and private backend, not custom speaker firmware. Physical microphone and speaker provide the interface; firmware exploration is future work.
