I have been trying to come up with some neat light effects for the Tokyo themed room I am designing for Sci’formal, but so far only the expected reactive LEDs come to mind. There are a few constraints that I will have to deal with. The biggest one is cost. I will be fronting this out of my pocket so it will have to be good bang for the buck. I think LED bars that react to the the music will be definitely cool but I will have to work with audio which will be new territory for me. I will have to start messing with a microphone and op-amps to filter audio and order a lot of LEDs. More learning is ahead!
