I homemade a gopro mount. did this by...
Cutting a library card (who needs the library anyway) in half lengthwise to make it super skinny. then, i used a flatmount onto the card. Finally, superglue to card lengthwise to the end of a trekking or ski pole. And remember, ductape is your friend, as it provides all your structural integrity. You just gotta get silly with it... and voila, you now either have a snowboard pole cam or a follow-cam pole mount..
hope i helped
