I’m working on an idea that I’ve been pondering over for a while: a simple, low cost option for networking low power microcontrollers for hobbyist projects, art installations, interactive exhibits, hackspaces, etc etc. There are a few options around, but nobody’s specified something to build an ecosystem around; radio is widely varied and problematic in many installations, and Ethernet is too expensive and high-overhead for small embedded projects.
Rather than reinvent the wheel, the plan is to use existing standards to specify a stack – physical, electrical, protocol and API – that multiple makers can produce compatible products for.
