Sebastian send us a link to an article that explains how visual diffs can improve open source hardware.
Doing change logs and version control with source code is easy to implement, since it comes down to comparing two text files. While trying to find differences between two revisions of the same hardware is a bit more difficult. The latter comes down to comparing image data.
The article goes to show how, with the use of simple software like ImageMagick or DiffPDF, managing and finding changes to different revisions of the same design can be made easy. It explains how these methods can be applied to both schematic and PCB gerber files. An interesting point is that GitHub now automatically supports visual diffs for image files included in commits.
