The new Nexus 7 is a fantastic gaming platform. But for some of use, the holy grail is to have a mobile gaming power with the better controls from a physical gamepad. Touch screen controls can only go so far.
In this instructable, I go though how to create a mount for a Nexus 7 Android tablet. It's light, cheap, and does what it is designed to do really well. Basically, BEST. ANDROID. ACCESSORY. EVER.
This can also be adapted to fit other controllers and other Android devices.
I made this at TechShop. The tools there really helped make this doable.
