99 Friday mask (music louder, smiler brighter!!!)
99 Friday is a traditional MIT Media Lab party which will happen once a month. Each party has a topic and Media Lab students will wear costume and have a great time on the party.
For the last 99 Friday, I made a mask which has a breadboard on it. On the bread board is a pure analog circuit. There is an electret condenser microphone that measures acoustic signal, and then a op-amp circuit amplify the acoustic signal to drive a smile like LED array. When the music in th party is louder, the LED array is brighter - music louder, smile brighter!!!
