Description PARAMETRIC CYMATIC SOUND BOX PURPOSE The aim is to construct a self regulating cybernetic machine that will effectually produce geometric randomness. The machine is to be environmentally unadaptive. Nonetheless, it is to be environmentally responsive. The machine will, in application, tap into a novel realm as far as architectural form genesis is concerned. Architectural forms which would be unattainable elsehow will be made realizable. OBJECTIVES: • That it responds and reacts to environmental activity • Geometrical forms are attained both randomly and parametrically. • That it performs input processing and output functions, owing to cybernetics. THE DESIGN The Hardware • Lighting fixtures: to sufficiently illuminate the operation plane thereby easing detectability of shadow behavior. • Light sensors: to detect shadow behavior and feed the arduino board information as detected • Arduino board : to parametrically compute information as fed by light sensors there by instructing the music player to produce sounds at specified frequencies. • Music player: to produce sound with instruction from the arduino board • A speaker operating within a 60-100HZ frequency range: to produce longitudinal waves which in turn produce dynamic effects on the liquid resting directly above. • Corn starch: At the right water content to be placed on speaker surface to produce oscillations. • Webcams: to capture activity on the working plane and directly produce a 3d video with the help of Stereo movie player software. • Laptop: to generate a 3d video and display to the operator

Description THE PROCESS Owing to the understanding of a cybernetic machine as adaptive in nature and environmentally responsive, the machine will perform sensory, processing and output functions. The output will be a form changing (dancing) effect of corn starch in response to different oscillations at specified frequencies as produced by a speaker in conformance with cymatic principles. The resultant movements and geometrical transformations will be captured by video cameras and with the aid of Stereo Movie Player software a 3d video will be generated. Since the fluid is in a constant state of dynamism, a different form will come about in every frame of the video. This then will ensure the attainment of forms of potential architectural applicability. Light will be projected to the working plane and an operator will have to create shadows by moving hands or objects directly above the operation plane. Shadow behavior will then be sensed by light sensors and fed to the arduino board. The arduino board will then respond to this information by working out and producing sounds parametrically as need be. Albeit the vibrations will be parametrically generated, the corn starch particles are bound to be in a constant state of reorganization, thereby guaranteeing operative randomness in both geometry and sound.

THE DESIGN

Preliminary sketches of the proposed machine, outlining the main components of the machine

THE PROCESS Owing to the understanding of a cybernetic machine as cyclic in nature, the machine will perform sensory, processing and output functions. The output will be a form changing (dancing) effect of corn starch in response to different oscillations at specified frequencies as produced by a speaker in conformance with cymatic principles. The resultant movements and geometrical transformations will be detected by motion sensors mounted above the activity/working plane and fed to an arduino board. The arduino board will then respond to this information by working out and producing sounds parametrically as need be.

Albeit the vibrations will be parametrically generated, the corn starch particles are bound to be in a constant state of reorganization, thereby guaranteeing effectual randomness in both geometry and sound.
