Hey — Just a quick note to say that the Teabox is now open source. The schematics, gerbers (for circuit board layout), BOMs, source code, etc. is all on Github @ http://github.com/electrotap/teabox

Of course, you can also still buy a Teabox (or sensors/accessories) @ http://shop.electrotap.com/products/teabox

Cheers,
Tim
