I had a major setback on my project today. With only 6 days until the event, I apparently fried my Hytechtoyz deluxe Cylon voice changer (which is the closest thing I've found to the Phantom). All I did was touch the battery backwards but that's apparently all it took. Back to square one on voice changing. With 6 days to go. I have the sound-to-light circuit ready, though.
