During lock-down in the UK, I finally could find time to take components from a concept of many years ago from shed and build the new, integrated media streamer and stereo power amplifier called Eumeles. It runs Mopidy, with an extension to control the VFD, and can be controlled from a mobile app or a web browser, e.g. MusicBox. More information on my Medium story, Eumeles-Integrated, or here:
Many thanks to the Mopidy community for such a great software package; I have tried a few, but Mopidy is outstanding.
