Main Hall
An ESP32 + I2S MEMS mic performs real-time FFT analysis and, via four amplitude thresholds, drives DC motors that animate a modular 3D-printed gear system, showing how sound energy can be visualized and felt mechanically, not just as light.
Magnetically mountable aluminum poles house battery-powered ESP32 nodes and LED strips that form an instant mesh network, no router required, for synchronized, choreographed light shows. Tool-free to deploy, reconfigure on the fly via a simple web interface, and occupy minimal footprint, ideal for Deaf-friendly spaces where visibility, access, and flexibility are paramount.
