Cool project and am glad to see RethinkDB getting some love, a couple questions, specifically about the hardware, came to mind:

Do you order the hardware and then place it wherever you like, or do you guys set it up?

How does shipping it work?

What is it underneath: Raspberry Pi + custom stuff (batteries etc)?

Will you be offering fancier machines later on, as in a machine that lets you input text?

Thanks for posting, i might well have use for this some day.
