BlueMesh

BlueMesh, developed by Eugene Yip, Jeffrey Yan, and the Department of ECE, is a comprehensive open-source circuit editor designed for both digital and analog circuits. It features an intuitive drag-and-drop interface, supports multiple browsers without any software installation, and allows for easy question generation and marking solutions. BlueMesh employs ActionScript 2.0 and is compatible with Flash Player 6.0. Its modular design also supports flowcharts and UML diagrams, making it an ideal teaching and learning resource for online assessments.
