As a linux guy for many years, the RaspberryPi is the perfect solution to my problem, and I'm already comfortable with the OS. Before you begin, make sure you read through my instructions. I have updated several sections through the past few months.
Just so you guys know, this is my first instructable after being a lurker here for almost seven years. I'm excited. So, let's begin!

As with any project, you will need some basic household tools. And some bits of wire. As for the cost, you should expect to spend around $400 for everything you need. Fortunately, half of the cost goes into the video glasses. Otherwise, a laptop would be a better option. Keep in mind that the computer part is $35 (without shipping)
