Phil,
What I ment was he may work on circuits that don't require a
certain type component layout. I have trouble shot micro circuits
where traces ran all over the board in order to get to their
destination. By using manual routing and a few jumpers, alot of
circuits can be done with a single sided board. Unless you know Eagle
very well it will produce a double sided board. Some people "Get to
the Getten" (American Chopper) instead of thinking things out like you
or me. I try for a single sided board with no ground loops. Explaining
manual routing to people who don't understand how circuits work would
require more work. Most people just enter in the schematic and accept
the board they get. I have seen tons of circuits on the Internet. Most
are missing the standard .1uf DeGlitching caps.

John
