We've shown you some awesome smartphone mounts you can buy, but if you'd rather DIY, you can have a strong, sturdy car mount for your phone with a few magnets and our old friend Sugru. Best of all, you can choose where your phone goes — you don't have to lose a vent or block something else just to mount it. Now, this isn't our first DIY smartphone mount. This famous one used a binder clip and rubber bands, but if you want a little more flexibility, all you need are some neodymium disc magnets, a coin (a magnetic one, preferably, or maybe some metal washers) and of course the Sugru. Use the Sugru to place the magnet on your dash or console — wherever you want the phone mounted. Then attach the coin (or washer) to the back of your phone or phone case with Sugru. Let them set up, and you're done.
Over at Instructables, Sugru themselves walk you through how to make this work, and have an alternate suggestion if you have a standalone GPS unit: Namely, two magnets on the dash and two coins on the bottom of the GPS, so it can stand upright while you drive. If you'd prefer your phone on the dash, you could modify the setup to work that way in landscape, You'll just need to put washers on your case for it to work, or create little bumpers with the Sugru so the magnets can stand upright and flush with the back of your case.
Either way, it's simple, affordable and customisable enough that you can find a way to mount whatever phone or device you have, anywhere in the car you want to place it. Check out the full walkthrough at the link below.
