For anyone interested, I've put together a build document on how I built my original trackball control panels. I sold these for almost two years before going to CNC built (and now phasing out even these). I have a sixteen-month-old with another one due in June so I've been allocating my 'free' time places other than controller building. A little more background info can be found in my project section (http://www.arcadecab.com/Projects/Ultra-Trackball_Original_Plans.html) or you can grab the PDF doc directly at http://www.arcadecab.com/Projects/TB_Plans/ArcadeCab's_Original_Ultra-Trackball_Plans.pdf. I'm not a writer so please be gentle. :)

I'm also middle of the way through another cabinet build for my brother-in-law. The writeup can be found at http://www.arcadecab.com/CabinetPlans2/CabinetPlans2_Tools.html. Nothing earthshaking or revolutionary, just another resource for beginners.
