Homebrew PCBs

Thank you for the help. I have the web-site bookmarked and will be investigateing negative developement. I only 
know positive developement thou. Does any one know of a tutorial in negative developement that they would 
recommend going along with this topic I have been following? Thanks Kevin

S**t happens. When you solve s**t, it mutates.
S**t never goes away. Entropy IS s**t.
Depend on it.
