You're lost in the wilderness and you don't have anything on you except your trusty mobile phone. What now? The Art of Manliness blog shows us how to use the phone's guts to make a bunch of tools, including a compass to help you find your way home.
Now, smashing apart your phone to make rudimentary survival objects may seem daunting, but if you really do get lost in the wilderness, you'd be shocked at how much you can make with it. The compass relies on just two small pieces of the phone: a magnet (which is usually part of the phone's speaker), and some wire (which is part of... everything inside the phone). After sweeping the metal wire across the magnet a few times, you can place them in a pool of water, and it should point you north.
Hit up the post at The Art of Manliness for lots more mobile phone survival tools, including (but not limited to) a snare made from your headphone cable and a spear cobbled together from sharpened pieces of silicon.
