Homebrew PCBs

Actually, it's the high ESR, which masks the lead and trace inductance. Or 
something like that. I'm sure others will correct this quickly if it's the 
least bit misleading or oversimplifying. The rule of thumb is one big, high 
ESR capacitor per board, and one low ESR cap for each power/ground pair per 
device. It's the small ones that need special care in layout.
