An EE friend of mine told me once you actually could make a noise source by
simply using a long string of resistors. A bunch of carbon film units, and
then amplify the signal and you're all set. They apparently generate a small
amount of "thermal noise" but you'd need over 100 resistors to get something
even worth amplifying. I think a crappy (hand selected to be crappy, of
course) zeener is a much easier method. ;)

tunable and very patriotic noise source)
