It took some logistic trickery, but we got five prototypes of the badge into hands of willing and skilled people, who will now test and improve the hardware, software and documentation. There is a repository at https://github.com/circuitpython-badge/circuitpython-badge containing what was produced during the sprints at PyCon.UK, and some discussions in the issues section. After the initial prototype design we can now hopefully take it to the next step, to make it fit the needs of the conference participants.
