I’ve done some work on the design. The major goals were to incorporate learnings from the current prototype and to simplify.
The battery is now completely separate from the light. Every person I talk to has different requirements and different views on how to power the light. Separating out the power gives flexibility and seem to the a sensible thing to do.
More mounting and attachment options. Camera rigs uses 15mm rods, so accommodating the standard seem obvious. Please see the video for details:
Getting the design right, or at least reasonably close to right, takes serious effort. This is not an easy banana to peel! I’d love to hear what you think about this design.
