Circuit Diagram is a free, open source application which enables you to make
electronic circuit diagrams and export them as images.
I started this project while studying A level electronics, having found no suitable
software to create diagrams for use in my coursework. Since making it available for

A web-based editor for making custom components for Circuit Diagram.
It includes a compiler that provides detailed error information and visual
previews as the component is created.
