This diagram illustrates how to fire off a BooTunes with a PicoBoo AC (105).  When output 1 is activated the BooTunes will play the input 1 MP3 file.  You can also share output 1 on the PicoBoo AC with other 110v devices by using a power strip.

You must use a relay with 110v AC coil so that the PicoBoo AC can activate it.
