Ultrasonically controlled instrument

[Rui] is working on a sequencer to control his robotic gamelan. The software maps out the controllers that operate the musical robot, which play the traditional Indonesian instruments.

The controls use ultrasonic distance sensors that detect the proximity of the musician’s hands. This data is collected by an Arduino and sent to a computer for use with the sequencer. The controller body is an upside down salad bowl from Ikea; cheap, available, and creative!

distance

Reader [Joshua] sent in his latest project. using a sonar rangefinder, an Arduino, and some clever programming, he’s made is computer react to his distance from it. As you can see in the video after the jump, he has programmed it to change text size and background color depending on his distance from the screen. While he admits that his implementation doesn’t seem immediately useful, there’s lots of potential¬† there. We can actually think of several uses. What would you use it for?
