I had an amazing time working on the Nagelier, the chandelier that nags you, at Science Hackday 2013. This was my first attempt at inspirational furniture — smart household objects that know about you and encourage you to reach your goals and be your best self.
To bring Fitbit data out of the internet and into the living room, Gabe and Michelle and I created an Arduino-controlled chandelier with an individually-addressable RGB LED strip whose light output is controlled by the user’s current Fitbit step count. A ruby script is used to poll the Fitbit API, quantify your progress towards achieving your daily step goal, and transmit the current state to the Arduino over USB.
If your chandelier is flashing red, you’d better get off the couch and go for a walk.
