Installing Armbian on Amlogic S912 Android TV Box (Tanix TX9s)

I love the idea of the Raspberry Pi, but there are some cheaper alternative single board computers that offer a similar experience for a fraction of the cost. While the community support isn't quite what it is for the Pi, there are a ton of projects you can accomplish on the cheap with these little hidden gems. Keep an eye on AliExpress and Amazon and you can find SBC's sporting quad core ARM process with 2-4 GB of RAM for under $30, including a power supply and IR remote control.

The box used in this video is a Tanix TX9s I picked up on GearBest for $24.99 shipped. It sports an Octa Core Amlogic S912 @ 2GHz and 2 GB of DDR3 RAM.
