[MakeLV] Etched Single-sided Arduino

[Will]

Comment and question.

Comment: If you want to save etching solution and make your lines cleaner,
don't remove all the extra copper from the board that isn't used. There is
no need.

Question: Are these boards going to be used for any arduino work shops? If
so, I have a cheaper and quicker solution to that waiting a little in the
space already.
