I recently bought a Nikon Coolpix S9400 camera, and have been really impressed with the video quality. I'd like to start documenting some of the routes I ride regularly, so would like to mount this on the bike.
First, the camera has the mounting threads at the extreme end of the case, right next to my left hand when shooting it hand-held. It makes me kinda nervous to think about the weight of the camera hanging off of the mounting screw on any mount, but if I can't find a mount that will fully support the bottom I'm sure I can cobble something that will deal with that.
It would seem that the best place to mount the camera is on the frame, not the handlebars to avoid the constant twitching as the bike is steered, though I might be wrong on that. If not, this suggests a mounting on the head tube. I can find plenty of camera mounts to go on the handlebars, but haven't found anything that might work on the head tube.
