    Slight clarification: It’s battery powered and has no energy generation or harvesting capability.

      If we're going to gatekeep "self-powered" this hard, might as well clarify that energy cannot be created.

        Let be honest though. Do you really consider something like your phone "self powered"? I know I wouldn't. My light switches that are powered by the click, those I would.

    There's much more information in the linked github repo at https://github.com/krauseler/muxcard

    It even includes an eInk display as well as the battery.Insane, but really impressive.
