Earlier this year, Dave wrote up an Instructables project on building your own smartphone dashboard mount. That one involved a fair bit of work, though. If you like projects that require few parts and even fewer minutes, check out the DIY phone mount.
It starts with a Garmin suction cup mount, which you can find on eBay for as little as $4.49 shipped. Then you pair it with the cheapest hard case you can find that's designed for your phone. (For example, Meritline sells an iPhone 4 plastic case for all of $1.99 shipped.)
All that remains is to saw the two ends off the bracket (which was originally designed to hold a Garmin GPS) so you have a flat piece you can glue to the back of the case. Presto! A seriously solid mount that's custom-fitted to your phone.
This looks way better than the wobbly goose-neck mount I've been using. Think I might just do a little shopping today. You? [via Lifehacker]
