Give your lifting sensor a voice coach — build photo from the creator’s source

What the hardware does

An ADR Encoder measures the motion of a lift and passes velocity readings to a Mac over Bluetooth, where a voice interface can discuss the current set.

How the agent helped

The creator says Codex built the command-line bridge that reads measurements from the sensor. This is evidence of a custom hardware integration, not a validation of its coaching advice.

Before you build

Uses a Mac and Codex Voice. Sensor integration is documented; training recommendations are not independently validated.
