Improving open source hardware: Visual diffs

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 […]
QR code generator script for Eagle
2D barcodes in Eagle: As i was preparing some boards for manufacturing (perhaps a 7400 entry) I thought it would be fun to partake in Itead’s OpenPCB program. But that requires me to have some identifying mark on my board and I thought a QR code would be perfect. Thanks honken! Via the forum.

Carving PCBs by hand
Carving PCBs by hand: Sometimes I need to make a quick prototype with a part that doesn’t match any of my proto PCBs, and I end up carving blank copper-clad with an Xacto knife (see attached photo of Cree XLamp XP-E LED with a center heatsink pad that would short out one or both power […]
