Homebrew PCBs

I'm getting the same thing.  Yahoo did this once before a couple of years ago.

  People:   What might be the reason that every posting made on this group since I signed on two weeks ago, hits my puter in triplicate?  Is this something the owner should know?

  Mike, i'm sorry there is no secret trick to get it routed the best way.
  It is a lot of trying, and much more art than anything.
  Arrange the components similar to the schematic to start with, and then
  move around to resolve most crossing "rubber bands". Leave enough space
  between the components to do this. The next step i do is deciding on the 
  board
  shape and moving the parts together again, starting to route the short 
  signals already.

  The autorouter won't do it right, at least for me.
  Remember you can use (few!) wire bridges to resolve problems.

  Boards: you can buy them at most electronics mail order shops. There is 
  FR4 (glassfiber)
  and phenolic resin (paper). second is easier to drill, first is better 
  quality.
  I buy my boards at ebay in big lots very cheap.
