My Original Chua Project

Morris and I working on the ChuaBack to where the madness all began. I just found this link to the first project I did involving Chua's oscillator as an undergrad in 2000 at the University of Illinois Urbana-Champaign with Morris Chukhman, who at the time was a graduate student in mathematics, for a class on the physics of electronic musical instruments taught by Steve Errede.

We succeded in building an analog implementation of Chua's circuit, learning about the details of the required components and where non-idealities were not acceptable. We then experimented with combining the circuit with traditional digital effects as well as perturbing the system with the output of an electric guitar, as in the photo. These sessions produced the recordings which led to the use of the system in my sound design project at SIUE with Nathan Ruyle.

What's the Solution?

Analog or Digital?

Analog - Physical and/or Electronic Interfaces

Digital - Max, Java, Processing, C++ (VST), etc.?


Many dimensional

High expressivity, at least in a few channels

Interface Approaches

Video Sensing

Hand Recognition

2 Hands * 3 Dimensions = 6D Control

Color Recognition

Use printed patterns and/or lights to control

Sensor-based Gesture Recognition

3D, Flight-sim like interface

Existing interfaces

Any ideas?
