Homebrew PCBs

I've gotten a few submissions so far, and right out of the gate have found substantial variations in how even the most basic Gerber specs are interpreted by different CAD vendors. Please keep them coming!

Especially useful are layouts where one or more copies of the same circuit are placed on the same board, or where the layout is rotated or flipped from the normal axes. Layouts that include text or artwork to be etched into a copper layer are also particularly interesting.

Many thanks to everyone who's sent me files!
