All of our open source and even closed source products are developed using the parts from our Pizzacake Altium Library, which can be found in the Pizzacake GIT repository here: https://github.com/spberglund/pizzacake. Feel free to use these parts for personal use, or within the requirements of the CERN Open Hardware Licence v1.2.
We're working on a fully functioning Star Wars BB-8 replica. You can see some of the progress on the hardware from Ryan's Vlog!
