Homebrew PCBs

If you use magazine paper, it is basically free to experiment.  Magazine 
paper works well for me, 8 passes through the laminator.  If an attempt 
fails, just clean the board and try again.  I DO make the occasional  
'proof of concept'  board  for  customers,  but  basically, it is a 
hobby. So even the time is free.
