Mood Base uses a Zigbee radio protocol, where a coordinating Zigbee, is housed within a large glowing orb placed on the floor of ITP. The orb or Mood Base sends out a heart-beat to a call-and-response network of radios in hand-held enclosures within close proximity of the base station. These smaller \”Mesh Pet\” enclosures, in turn, send out their current mood status, determined by a potentiometer controlling pulse (excitement level) and another controlling a range of colorful LED moods. Each of the four pets will have a different personality, augmented by lights, simple sound-generating hardware, and unique fabrication. On the Mood Base the collective mood of the group is summed into a more complex relay-driven light display and vibrating sub-woofer drones, resulting in a playful a communication of light and sound.
