Hey, everyone:
While using a wall-wart directly is probably not a good idea, you might 
want to see what Terry  (WA0ITP) did to solve the problem.  Essentially, 
he epoxied an LM7812 and heatsink to the back of a wall-wart, added a 
couple of capacitors, and checked the output for any ripple.  Finding 
none, he dubbed it the "Motel Power Supply" and is good to go for QRP 
operation from a motel.  But you can go to his website (below) and read 
for yourself.  He has quite a few good ideas on that website.

Happy holidays to all!
