Hey Bourno I am electronically challenged but was hoping you might help me with a question? I really want to hack my $5 mp3 player, and was motivated by your page on the process. My question is, based on what I see, if I solder the ground wire as shown and install the other wire on the battery mount like you did, I should be able to trigger this with pretty much any typical prop controller right? I assume i would simply connect to the ground and an output contact on the controller like u describe with the prop-1? I look forward to having real mp3 sound with my haunt this year so this is where I start. Thanks in advance for any help you can offer. Regards John
