With DIY gear so readily available, building your own controllers can be fun, rewarding and really creative. Here, Liam Lacey shows you how to make your own 3D gesture-sensing USB MIDI controller.
Thanks to the recent development of the Microchip MGC3130 gesture and tracking chip, a number of new affordable sensor boards are being introduced that allow you to create 3D hand gesture and tracking devices with ease and for less than $40. One range of these sensor boards is the Pi Supply Flick range – a set of surface-mountable boards that can detect seven different specific hand gestures as well as 3D XYZ tracking within a range of 15cm, which also have touch sensing for 15 different types of touches. While most of the Flick boards are designed to attach to Raspberry Pi boards, there is a standalone Flick board which can connect to any other I2C enabled microcontroller or microprocessor such as Arduino, Teensy, or BeagleBone.
