I'm in the process of finalizing the designs for an open source hardware project (a pressure sensitive iPad stylus, see http://facebook.com/pressurepen ), and I'm at the point where I want to publish and share the various designs. I have 3D models on Thingiverse and Shapeways, and the app source is on Github. How and where should I publish the circuit diagrams and the files for the circuit board?
I imagine a standard format for the PCB files would be Eagle, but I think I'd like to publish the circuit diagram or schematic as well, so someone could design their own PCB based on it. Is there a standard format and repository for such things?
