Kit74 is an 8 relay device connected to a computer printer port. The video zooyorkag posted had some dimming and fading of the lights besides just turning them on and off to the music. The Kit74 would not be able to do that, just On/Off control of the lighting. I think for the fading effects you would need DMX controllers or something that can fade the lights.that is done using a Kit74 most likely you can find these online pretty cheap, you hook it up to your computer and it will run 8 electronic anything. then use brookshire VSA to run the board .
