odd lpc problem

damn, that was the fastest response i've ever seen...
i was coming back to edit and say that the lm1117 heats up kinda fast... I don't get why, though. if the diode draws 3v, it should be releasing only about 1.5v, which isn't a whole lot, right?
If it's heat, how can i prevent it? the diode is in an aluminum heat sink, and doesn't even feel warm when the lm1117 is gettin' hot.
I don't get why the trimmer would act the way that it is, either
