- | ===== Schedule ===== | + | A workshop for an Chua Circuit with in an analog computer to generate |
+ | chaotic signals, noise and sound. | ||
+ | This circuit generates chaotic signals over a wide range of frequency | ||
+ | therefore it is an interesting device for noise and sound art, | ||
+ | performances and installations.\\ | ||
+ | \\ | ||
+ | In the 1970th Edward Lorenz developed a mathematical model for the | ||
+ | weather and climate prediction, the Lorenz Attractor, a strange | ||
+ | attractor with chaotic and fractal behavior and sensible initials | ||
+ | conditions, that in the end could lead for example to a tornado in | ||
+ | Brazil - the so called Butterfly Effect. | ||
+ | At that time it was not possible to compute this module with in an | ||
+ | analog computer, the chips for doing the multiplication were to | ||
+ | noisy. That’s why in 1983 Leon O. Chua introduced a much simpler | ||
+ | circuit (no multiplication) with the same chaotic behavior, the Chua | ||
+ | Circuit.\\ | ||
- | === Part 1: Background, Introduction and Build === | + | The Analog Computer Confetti is a modular system that makes it |
+ | possible to perform all kind of computations and operations on base | ||
+ | of electrical voltage. This stack able modular electronic analog | ||
+ | computation system was and is still developed by Wolfgang Spahn since | ||
+ | 2015.\\ | ||
+ | \\ | ||
+ | Chua’s Circuit can be made out of two modules of the analog computer Confetti, aGyrator and the Chuas Diode. The analogue computer Confetti is a modular system that makes it possible to perform all kind of electronic computations.\\ | ||
+ | \\ | ||
+ | In the workshop we will learn the basic functions of an analog | ||
+ | computer. We also will build the two main components for an Chua | ||
+ | Circuit as modules of the analog computer Confetti: a Gyrator and a | ||
+ | Chua Diode. With these two modules we will create the Chua Circuit to | ||
+ | listen to the butterfly in our tornado.\\ | ||
