Could you imagine that a so simple schematic provides touchless and gesture control?

Here is our 3Dpad recipe:

• First, take a small 8 bit microcontroller,  Atmel ATmega328 on Arduino Uno for instance
• Then you'll have to find a good old HEF4046
• Just add few well known "stock components" around him
• Don't forget to make an electrode plane PCB

Well done, you've got it!
