Find a safe, no-cost and teachable method for attaching a Mobius Actioncam to a dowel
I started with a double "barrel hitch" knot, with the string ending in two overhand loops.
I took a keychain (could be a paperclip or whatever) and formed it into a horseshoe shape, with slight out-turn at the ends.
I marked the dowel at approx crossing points, then nicked little slots with a knife.
Then I put the dowel in place,, and spun the horseshoe to cinch it all down. Then I tucked the end of the horseshoe under the taught line to lock it in place (see main image).
The whole unit is just a rubber stopper, small-end-up, over the dowel and going into the neck of a 1/2 soda bottle. I left one end of twine long, so it could protrude through the neck, potentially clipping it to a carabiner as a safety should it slip off the dowel for some reason.
Questions and next steps
What do you think? Is this too complicated? Is it actually worse than rubber bands, safety wise?
