Homebrew PCBs

jcarlosmor,
           The direct method started out using floor wax. One guy was
telling people it was a done deal. I milled my circuit boards at that
time. There were people who pointed out that milling could not do fine
traces. While they discounted my efforts I sold hundreds of milled
boards for profit. I could produce a 4" X 6" board with lots of traces
for around $7. The same board done at a place in Texas cost me $16.50
each in lots of 30. Then I went retro producing booklets showing how
to perfboard a project and turn that layout into PCBoard artwork. 
         The direct method now works after years of hard work by a few
people. No matter what method you use you have to stay with it until
you iron out the bugs. All methods give somebody a problem. Just read
the posts.
