It is essentially a re-purposed bike reflector mount with a plastic plate screwed to it, onto which the camera is mounted via elastic bands/cable ties or anything similar.
There are many instructables for mounts which hold standard digital cameras (using the tripod screw hole on the bottom) but I needed to attach my phone or other devices, so I had to come up with a more universal solution.
Enjoy the huge photo count! :-)
Videos of this being tested will be on Youtube shortly...MAYBE.
