Homebrew PCBs

Here's a good site I've used, for anyone who may want it:

http://www.interq.or.jp/japan/se-inoue/e_eagle.htm

There's some good polygon stuff in "Grounding pattern making".
(in the "Board making techniques" section)

BTW- As Ted mentioned, remember your fill patterns won't appear until 
after the ratsnest command, so even if you close the board, it'll look 
like they're gone when you re-open it. Totally screwed me up for a 
while. :(

Also, remember you can change any of those layer colors (or names too, 
I think). You just double click the colored square or name in the 
"Display/Hide Layers" list. I often switch a couple of the weird ones 
to a light colorful look, to draw temporary traces and stuff, so I can 
easily see them against the regular top/bottom layers.

Take Care,

George
