Do you feel that you have a little bit of extra time on your hands this coming weekend? If you have answered in the affirmative, then perhaps you might want to check out this particular DIY project – which is a wearable light organ that can be activated by sound. Measuring roughly the size of a couple of 9V batteries (while running on one, of course), the Light Organ that you see here is not only portable but fun.
Right smack in the middle of things to keep it groovy and funky would be the LM324 Integrated Circuit (IC), which is actually the black chip in the middle of the board. Coming with a quartet of operational amplifiers embedded, only two are required for this project to converting sound into light through the condenser mic element. Perhaps the video after the jump would be able to give you a better idea on how it works?
