I needed a way to easily mount 2 GoPro cameras to video snow blowing action by the Kubota tractor (before the snow melted). I wanted one camera on the tractor and the other on the car parked in the snowed-in driveway.
Luckily I saved the packaging materials that came with the GoPro cameras - and the packaging happens to include a square plastic base with an integral GoPro base mount - perhaps something that's meant to be thrown away.
I ended up securing two neodymium magnets to the plastic base so that I can quickly mount and unmount the cameras to any magnetic surface.
It took just a short time to make the magnetic bases and they now are an important part of my GoPro camera gear.
The included video shows the snow blowing action that I captured with the help of my GoPro magnetic camera mounts.
Step 1: Attaching magnets to the plastic base
Epoxy will likely hold the magnetics to the plastic base securely enough but I happened to have some steel "magnet cups" on hand that attach with flat head screws. For this project I used wood screws but flat head machine screws and nuts would be a better alternative.
Step 2: Tools and materials
Step 3: Camera mounts as usual but be careful
The camera mounts to the (now) magnetic base the same way it mounts to the other GoPro accessories. But be aware that the neodymium magnets grip very tightly and removing the magnetic base might possibly mar or scratch a painted surface.
I plan on attaching thin felt on the surfaces of the magnets for my next job.
