Homebrew PCBs

Thanks for the feedback.  Lots of points and questions:

- I've looked into the various usps options and there are several that
are quite reasonable.  especially if it can be in an envelope form
factor - $3.85 for a pound anywhere in the usa.

- no unclad FR4

- I'll need to determine if it really is 1 oz or .5 oz.  the stuff I
got has a number of stacks of boards labeled "FR04 1 oz/1 oz".  Since
I bought it in a lot at auction, I don't think anyone was trying con
me - the guys running the auction had no clue.  I guess I need to do
some googling and weigh the stuff.

- eagle compatible size - really great idea!

By the way, I also got, as part of the lot, a bunch of aluminum clad
particle board.  It makes a fantastic drill backer.  Tke drill exit
holes on the bottom are quite clean.  Better than any other backing I
used.
