June 23, 2017Categories: Hardware, Tutorial
I've decided to put in a knob to control the volume directly on the box itself. It will be controlled by volumio itself via a plugin, much like the GPIO Buttons plugin. Since this is really a development kit approach, the hardware consists of: A KY-040 rotary encoder and A screw-based prototype…

A while ago I've decided to try my hand at replacing my Sonos system with a DIY version of a sound system.

HifiBerry Pin Usage

June 13, 2017Categories: Hardware, Tutorial
