Duf,

I like CBO's idea of laying the job out on paper first to help you "own the concept" so to speak. That is just what I have done in several boats and classic car restorations. It really helps to visualize something like this. That was a good suggestion. In my humble opinion, I suggest you do not look at any more intimidating photos! Rather, let your brain "see" your schematic and then just build it. Decide on paper what method of coding you want to use.
Good Luck my friend,
Grady
