Dreaming of making my own OS- what should I use? (suggestions) [closed]

I was just wanting to go ahead and make an OS. Because working on projects makes one's knowledge quite good enough. I know I will have to study OS inside-out before actually trying to implement one on my own. I also know I wouldn't be able to implement something right from square one. So I searched the internet for something to work upon. The most common option that I found was to work upon existing Linux distro and contribute to it. But I found some more interesting options. Would like your suggestions on what to choose for and work upon.

I would get around 6 months time to work upon it. But before I start off with it, I want to do my research work properly and finalize what and how to work. Drop in your suggestions on what should I use to work on. :)
