This is a very easy project to make a Mobile Phone / Tablet / Phablet Stand using just a paper clip. The phone can be held in either the landscape or portrait mode. The phone that I used to test this out was Motorola Defy which is a 115g phone. The Tablet that I used to test this was Nexus 7. The trick of this stand is that it uses the device's own weight to prevent itself from toppling over - just like a bookend.
Level : Easy Cost : $0 (approx.) Time : 2 min
I have also discovered that if you use two of these paper clip stands you can easily support a Tablet in landscape mode.
There is also a video to this and if you want you can jump directly to the last step to go to the video.
