Ever been inspired to mount your Gorillapod tripod on a metal surface, but can't find a suitable grip? If you are a creative photographer, then you should check out this Instructable that shows you how to modify an existing Gorillapod by adding some magnetic feet.
The detailed directions were created for the standard Gorillapod model that's compatible with a camera, but you can use the same steps to modify the iPhone version. The process is not too difficult, requiring you to drill a small hole in the bottom of the tripod feet, fill the hole with a magnet and use epoxy to hold everything in place. A final coating of sugru helps to give the feet a smooth, professional-looking finish.
If you are a savvy shopper, the cost of each magnetic Gorillapod can be quite reasonable with each unit requiring about $25, though you may have to shell out $40 to get everything you need. You will need a $16 Gorillapod, a $12 pack of ten rare earthmagnets (1/2" x 3/8) and about $12 in sugru. After using three magnets and a touch of the sugru, there will be plenty of supplies leftover for future projects.
It's a clever and relatively inexpensive modification that'll provide a novel way to hold your iPhone while you position it to get a unique angle shot.
