Thanks! The project we started up, IoT Toolkit, is nominated in the Open Source category. We also use the Raspberry Pi and EVE Alphahttp://postscapes.com/awards/category/open-source-project
Raspberry Pi runs Open Source software but the hardware design itself is proprietary to the Raspberry Pi foundation.
By comparison, the Schematic and PCB files for EVE alpha are available on Github under an Open Hardware license. I have made my own EVE boards already.
I also have a question about the open-ness of Ninja Blocks. They provide an open client design but their Ninja Cloud is proprietary. I believe you need Ninja Cloud to make it work. So... is it Open Source?
