MOTM

I just finished my TM, too.  It's not quite right, so here's my 
question: U20 is heating up more than I think is healthy.  Double-
checking everything reveals only one mistake (which I will correct 
tonight) - I put the LED in backwards.  Would this cause overheating 
in u20 and the unit not to work?
