Motion-sensing bathroom noisemaker – made with the Chumby hacker board via MAKE.

Recently I was approached by an architecture/design firm to help with an electronic install at a client site. The client had requested a system that interacts with users in the bathroom- “interacts” meaning, hassles them when they come and go.

(…) The system has three events- enter, exit, and “loiter”, and sounds in different folders on the USB drive will be played for each event, allowing users to change the sounds later if they wish.
