What the hardware does

Touch sensors activate a voice interaction while an Arduino-controlled light ring signals conversation states inside a physical crystal-ball enclosure.

How the agent helped

The creator credits Codex with the voice application, Arduino firmware and integration between the Raspberry Pi and lighting hardware. The divination theme is entertainment, not a claim of predictive accuracy.

Before you build

Physical prototype requiring wiring and cloud voice service. Astrology is entertainment, not an evidence-based prediction method.

Astrology output is entertainment, not a factual prediction. Keep the speakerphone external as the source describes; no microphone amplifier is needed if using the documented USB speakerphone.
