The bathroom indicator

The purpose for this project was to create a simple and lasting solution to an everyday problem—knowing when CIID’s 1st floor restroom is being occupied—through the use of basic electronic circuitry and a variety of conductive material.

To do this, the team created an open copper wire circuit that connected two LED lights to a resistor, a 9v battery, and two pieces of conductive fabric on each end.

These fabrics were then placed within the door frame’s strike plate on opposite ends of the hole where the deadbolt fits in.  Once the door locks, the deadbolt is inserted into the hole and then comes in contact with both conductive fabric cushions. Since the deadbolt’s metal is conductive, the circuit closes and thus allows for the electricity to flow from the batteries to the LEDs.

In an attempt to further broaden the restroom experience, the team attempted to create a more complex circuit that would be placed within the restroom and would create a visual provocation of a cascade of LEDs which would simulate urinating.
