Ironically enough I had my last working DMD board start acting up on me today. We tried to repair it but the board has disintegrated too much from the years of heat. But of course the logic section is still good meaning it will work with a low voltage display. So after seeing what winteriscoming did with his JP we said, "What the heck?" and decided to outfit our Addams Family with a "poor man's color DMD." Winteriscoming, thanks a heck of a lot for disclosing the details of your build. I have absolutely no experience working with laptop displays and how the controller must be programmed and wired to work with a specific brand of panel. Listing the exact parts you used saves me a lot of time and trouble. Plus, your work looks awesome!! The Rasberry Pi arrived today, just waiting on the Extender, converter board, and LCD. Man this is going to be one sweet mod...

I have written a brief connectivity guide for large Sega displays, but it will work with any setup as long as you have the correct parts for your game and configure the software to use the correct machine manufacturer setting. The new version of the Extender uses Raspberry Pi model A plus/B plus now.
I will also be following Herg's Tron conversion for guidance: http://pinside.com/pinball/forum/topic/diy-colordmd-installation-in-stern-sam-tron
Update! ALY has written a fantastic setup guide to supplement my instructions.
And HighProtein has made a great setup video explaining the entire assembly process.
