Mount a spinning pole with a GoPro, on your helmet and get some interesting camera angles! I designed this one specifically for my helmet (Bern Macon). Safer than comparable models out there as you don't screw anything into the helmet. In the event of a crash, the 3D printed parts will break instead of your head!
Quick demo video, cheesey, I know!!!
(x1)1/2" PVC pipe
(x1)GoPro of your choice
Counterweight (In this case I used a small can of food but typically a bolt and nut with washers does the trick)
(x3) Ball Bearing 625 2RS 5x16x5 (I used leftovers from an Openbuilds project)
(x1) Nylon Insert Hex Locknut M5

I recommend sourcing these parts from somewhere like your local Fastenal or other similar nuts & bolts store.
Screw the M5 screw up through the HelmetBottomMount. Place the precision spacer and then the bearings onto the screw. Tighten down with the M5 nut. Next place the PVC pipe through the HelmetPoleMount. Insert the first assembly into the HelmetPoleMount. Tighten the M3 screw into the side of the HelmetPoleMount. Add your handlebar mount and GoPro to one end of the PVC pipe and add counter weight to the other. Done.
