Description

The LED Façade is a trifold panel device placed at the front edge on a DJ's table. It contains strips of individually controlled red, green, and blue light emitting diodes (LEDs). This product was created as a part of an engineering design project in the Spring of 2012 to create a set of low cost and feature rich devices for use by a DJ at events. Existing façades are not synchronized by a music beat or they are expensive (over $7000). This cost-effective equipment will help fill the gap in the market. At the start of this semester, the LED Façade’s structure, lighting, and diffusion elements were already designed and built, but the controlling software and beat synchronization capability was still in a rudimentary form.

This semester (Spring 2013) we designed a LED Façade controller which synchronizes the lights with the music for approximately $100.00. The project consists of several components: • Beat extraction hardware and software algorithms for use on a live audio feed. • Audio visualization effects for display on the façade. • A user interface for the façade that gives the end user options to customize the behavior of the display. • A user manual that describes the procedures for all operations of the façade. Beat detection has numerous applications in medical, automation, and audio processing. Developing a highly accurate beat detection algorithms is still under active research areas. We learned signal processing and advanced topics in electrical engineering by doing this project.
