Piezo sensor, Arduino, synthesized audio, Pepper's Ghost holographic effect

A brutalist-inspired interactive installation that transforms physical impact into ritualized digital response. When viewers strike the slab with a small stick, a piezo sensor detects the vibration and sends data to an Arduino microcontroller. The system triggers a synthesized w soden fish percussion sound while simultaneously activating a l olographic Pepper's Ghost effect that manifests a cybernetic "karma blessing."

The project merges spiritual symbolism with embedded electronics, translating gesture into sound and light. By integrating sensors, real-time audio synthesis, and illusionary-based projection, the work demonstrates skills in hardware prototyping, signal processing, and interactive system design. The installation invites participants to consider how action, feedback, and belief operate within both technological and cultural systems.
