Making a Gesture

When [krich] switched keyboards he lost his volume control. So he decided to hack one together out of an Arduino, an old floppy disc case, and a Hover Labs Hover board (not the Back to the Future kind). You can see the result in the videos below.

You’ll notice in the video that the device reads a “spin” motion to resemble a round volume control. The program sends simulated keyboard presses to the PC to control the audio. In the write-up, [krich] mentions it may be the first gesture-based volume control. However,we’ve done it before and so have others.

The Hoverboard does all the hard work, of course. It passes data to the Arduino via I2C. The PC side is handled by some Windows on screen display software, 3RVX.

Still, this one seems to work well with the Hover board. Hard to argue against anything that upcycles a floppy disc container.
