Today we have published the design files for the OggStreamer – which you can find on sourceforge: https://sourceforge.net/p/oggstreamer/pcb-design/
The design was done with PCAD 2006 – so you might need a viewer to have a look at the files. The Viewer can be downloaded here.
We used PCAD 2006, because it was the only feasible option for us to use at time we started the project. But we would be very happy if somebody could translate this Files to an OpenSource EDA-Tool like KiCad or gEDA
