[sdiy] Aaron's first PCB layout

[Veronica Merryfield]

I forgot to mention this other than the divided 0v. It is not a good  
idea to run one signal line right round a board like this because of  
noise/crosstalk pickup and because of any propagation time, but I  
assume this is probably not an issue. However, there is a path for  
that trace without going between the ground pins and without removing  
all the ground plane, although removing it that would make it easier.
