Story

1 / 11 • LEDs to depict moss condition

Zenrack is a dishrack that promotes cleanliness and peace. Rocks and moss line the bottom of the device that absorb water and keeps the bottom from growing mold. Moveable crossbeams embedded with force sensitive resistors sit across an acrylic box to support a variety of dishracks. A separate compartment houses the electronics to keep them dry.

When dishes are placed on the Zenrack, tranquil music will start playing to encourage the user to continue to wash dishes. Music will continue to play as the user continues to place dishes on the rack. After all dishes are done, the music will stop.

A moisture sensor keeps track of moss conditions. This is hooked up to an array of LED lights so that is the moss is amply wet (dishes are done often), the light glows blue. If the moisture levels are okay, the light is orange. If the moss is dry (dishes haven't been done for a while), the light shines red.
