So I have decided to finish this up and use it for my entry into this year's Hackaday prize. I think this is just the motivation I need to complete this project. I dropped it a while ago and it has been collecting dust, but always at the back of my mind. At the time, my Eagle skills weren't really up to the task, but I have since practiced and made a few smaller board and think I am ready to tackle this task again.

That's the new project page, as per the Hackaday prize rules. Follow/like/skull me over there to get the latest updates on this project. I will still update this project occasionally too, but the aforementioned one will be the main headquarters for updates. It is a placeholder now, but I'm going to fill it with all the research and relevant information from this project shortly. Thanks!!!
