The GoPro camera is a great tool for getting point-of-view videos, but challenges arise when you want to mount the camera to, say, a car. Instructables user gjchandler offers a simple solution: use magnets.
To put this mount together, you'll need washers, bolts and a disc magnet. You can also use the standard GoPro tripod mount for this project. All in all, it's an inexpensive way to mount an HD camera on your car. If you want to give it a shot, check out Instructables for the full how-to guide.
