Hi All!
I'm working on a light organ project that I found through Collin Cunningham YouTube channel. You can find the youtube video about the project here:

I purchased the kit for the project from Jameco. You can see the kit instructions here:
http://www.jameco.com/Jameco/workshop/diy/ledcolororgan.html
and a parts list here:

You can see the schematic for the project here:

I've essentially finished all of my soldering and I've hooked the board up to a 12v DC power source and the LEDs will initially flicker on when I do this, but when I plug in my ipod (or any music source) just the blue and yellow LEDs will flash together about every second or so, but the lights do not react to the music playing.
When I hook the board up to a y-connector to play music into the board and a speaker simultaneously the board actually seems to be emitting it's own sound that is picked up by the speaker and sounds like a distorted bass drum sound.
The one part of the schematic that I was unsure about is the connection from the 100k resistor to the VCC when it comes out of the 3 pin in the MC34072P. I wasn't sure if the VCC was meant to be just the power source or potentially another connection. In the end, I just connected it to power, but this could potentially be a mistake on my part.
I am also fairly new to soldering, so it's possible that some of my joints could be shorting, but I'm not sure where.
I've taken pictures of the top and bottom of the completed project:

Any help with finding my error or at least pointing out the most suspect soldering joints would be really helpful. I'd love to get this project fully working.
Thanks!
