Lady of Shallott is a DIY analog water sensor using Arduino and Max/MSP. It was loosely inspired by this scene in Anne of Greene Gables, where Anne almosts drowns when reading poetry in a canoe.
 

Genius moment: blowing up a balloon in the doll head insuring its buoyancy.

Stainless steel wire was the best material because it didn’t corrode. I used other wires previously. Some sort of chemical reaction was still created.

The analog read from Arduino went into Max/MSP, which then looped through specific frames when the doll head raises the water level to each wire.

Power and stainless steel wires going to the Arduino’s analog in.

When the view pushed the doll head underwater, my friend Bayla seemingly floated underwater.
