We here present a series of design explorations focusing on batteryless interactions powered by hand cranking body movements. The explorations concern not only the matter of powering but also the use of human physical engagement for controlling interactive systems, as well as how to support designers in testing, exploring, and making such interactions. This pictorial illustrates contributions concerned with the embodied and electro-physical prototyping of such experiences, in addition to our efforts to facilitate such design work through new technical tools.
