[sdiy] PC board from artwork?

[David G Dixon]

Hi Terry,

I can rework the layout to accommodate more typical quad opamps such as
TL074.  This is actually very easy for me to do.  I do it in Excel.  With
the graphic and the schematic from the article, I can reproduce the layout
in Excel very quickly and then manipulate the layout to change the opamp
pinouts.  No problem.

I could also add some sine shapers if required.  I have a nice design for
sine shapers which I could basically drop onto the board.  It would get a
tiny bit bigger, though.
