Sky-writer - a electrical near-field sensor for 3D gestures

Hey everyone, recently got hold of a sky-writer which is an awesome little electrical near-field sensor for 3D gestures. I was surprised how easy it was to set up and how accurate the readings of the gestures.

Here is the code to get basic readings from the sky-writer (tap, swipe, air-wheel)

I then used this to control my lifx lightbulb. Where a tap would switch the light on, a swipe up/down would adjust brightness and a horizontal swipe would change colours.
You can take a look at the code here and see a little demo below.

I’ll put together another demo once I have built a better housing for the machine. If anyone has other cool ideas on how to use the skywriter let me know!
