Turn a smart phone into a signal gerator

[Phil]

"The smart phone signal generator can be built for less than $15! The hardware consists of a single stereo 3.5 mm headphone plug, some wire and then optionally three alligator clips to connect the signal generator to the test device."

Cripes, $15? Where are they buying their parts? Radio Shack?

Nice idea, needs a simple interface for the reasons given.
