Homebrew PCBs

You may have spend more then $20 for the guts...........

But there is no reason to go high cost for the rest. It's not  
difficult to build everything in a smaller container like a small  
wastebasket or plastic lidded filebox, and use that in something like  
a small plastic trashcan with a cover..
