Make Weekend Projects - a touchless 3D tracking interface

[Video Link] This Weekend Project from MAKE is really cool: a touchless 3D tracking interface made from foil and cardboard.

Using a combination of low- and high-tech components, we'll show you how to build a completely touchless 3D tracking interface. This project will introduce you to the principle of capacitive sensing, and the Arduino microcontroller.

Complete instructions for this episode of Weekend Projects can be found here

Wow, this is great. I may have to make one so I don’t have to get out of my recliner to get a beer. Wondering if there’s a way to make it without soldering. Soldering worries me.

Could use this to make a theremin sort of thing.

This could be used to make a theremin with an added Z axis, (controlling flanging or vibrato?)

It could also make for one heck of a MIDI controller.

I got a project now. :-)

  Ring modulation. Control amount of ring modulation with the z axis.

    Love this idea. Flanging or some kind of echo on the Z axis, perhaps (or maybe add an LFO)?Vibrato and tremolo are just shivering in the X or Y axis – you wouldn’t need a Z axis for that as much as a really cold room.

  Had the exact same idea. You would need to make two of them, one for each hand.
