Abstract

A modular experiment board for hands-on exploration of sound generation using simple 4000-series CMOS logic ICs. Developed at the Karlsruhe University of Arts and Design (HfG Karlsruhe) within the Circuitry-Based Sound seminar. Unlike conventional synthesizers or DSP-based systems, the board relies entirely on discrete CMOS logic chips arranged as a patchable interface for experimental sound creation and live performance. This deposit archives version 1.0.0 of the documentation: complete EAGLE schematics, Gerber files, mechanical drawings, Bill of Materials, and the build guide for hardware revision 2.0 Rev B.
