Phil,
There are tons of circuits out there where the component and
trace layout is not important. Chopper controllers and audio amps are
a different story. People who write books tend to get the job done
quick and go for the money. Don Lancaster's TTL Cookbook was one of
the first books to knock my socks off. That book is stuffed with tons
of easy to understand info. Others write books based on one project
and in most cases it lacks refinement. I have gotten two articles
published and I got paid for them. What I sent and what was published
was different than my vision.
I protoboard my circuits. Then I perfboard them to refine my
layout. Then I Eagle or CAD the traces.
