I once wired a board up the wrong way, where the net result was that the 
12V and 5V lines got shorted together. I didn't notice for a while, 
until I saw it wasn't working right. Board had two PICs: a 16F877A PLCC 
version, and a 16F876 DIP version. Some 74HCxx logic thrown around too. 
The 876 went toast, but everything else survived. The 7805 that was 
regulating the 5V line from the 12V one just got hot, but was otherwise 
undamaged. Good thing too, since I really didn't want to resolder the 
PLCC chip (the 876 was on a DIP socket).
