Scanlime’s Beth modded a remote control vibrator, replacing the interface with an Arduino-based sonar controller that she can activate with any part of her body, playing it like a theremin. The result is pretty cool — it “closes the feedback loop” between the vibrator’s intensity and the user’s physical response. The post includes a detailed technical breakdown of the reverse-engineering steps that she used to work out how to hijack the control mechanism, and the steps that went into building the remote, including a 3D printed chassis. The plans are open source hardware (CC-BY-SA), and posted to Github.
via Open source, sonar-controlled vibrator you play like a theremin, with your whole body – Boing Boing.
