Circuit Diagram

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 others to use, it has had over 140,000 downloads.
