I received my talking skull kit on friday and assembled it yesterday. I put a bunch of time into programming the audio, (pirates of the carribbean) using the technique posted by Cessers on the cowlacious website, in which you use a 12-15khz tone to mirror the audio that you want the servo to open with. only thing is that I want to put it on an ipod to stuff in the skull, but it doesnt properly relay the 12-15khz tone. so it works when it is plugged into the computer, but not when plugged into the ipod. does anybody have any ideas? what audio source do you use with your talking skull, CD player, ipod PC etc? what format do you record your audio in. mp3 doesn't seem to work for me. help please!
