Create Your Own Linux-Based TV Dongle for $ 40
There are tons of ways to install Linux on your TV, but in Node they demonstrate how to create your own little dongle that you can take with you wherever you go.
The dongle is powered by ODROID-W, USB hub and Raspbian. You’ll need some soldering skills to get everything hooked up, but once you’re done, you can plug it straight into any TV with an HDMI port, no extra cables are required. It’s ugly, but since it’s hidden behind the TV, it doesn’t really matter.
