very simple and useful. I suppose the extra GND holes are for good measure?..... and I'm a hardcore perboarder, so pardon on this supposedly silly question for a person with a post count like mine, but can you post me a link on producing wicked-lookin' PCBs like that? I have juuuuuust started on the simplest and disgusting-looking ones (the 10-dollar apiece, printed circuit by using an iron press, yadda yadda one), and yours look like it's ready to be mass-produced.
