Audio Graffiti

For my midterm project, I hacked the sink in our 10th-floor bathroom.


The sink had an IR sensor with an exposed control box. I cracked that open, split off the power and sensor-data lines, and got it trigger a light show under the sink and play a sound sample from a speaker I attached under the porcelain. I left a record button hooked up to it, and, pretty soon, people were recording their own strange sounds and messages that would play every time someone went to wash their hands.
