Palette - Capacitive Addressable PCB touchwheel

Palette was intended both as a tool and a design exercise.

It uses side-emitting individually addressable LEDs facing inwards so that the colour mixing is done on the white surface of the PCB board.

The PCB is a capacitive touch wheel, which allow colour & brightness selection, similarly to the original iPod touchwheel.

The driving microcontroller has WiFi & Bluetooth 4 connectivity, allowing to output the selected colour onto wireless DMX fixture, for example.

I developed the electronics and the firmware. The design was made in collaboration with Harish Persad.
