Multifunction radio
Description
# Multifinctional radio - current design is adapted to OrangePi Zero but can be migrated to use RaspberryPi ZeroW - design for inner usb-hub is for non hub that I had laying around so provided link to usb-hub is just for reference - based on the version of pc used for build wifi/bluetooth/dac dongles are not needed - design for CD/DVD drive is for slim version of notebook drives - for playback is used [Volumio](https://volumio.org/) and Opi Zero uses img from [Volumio Forum](https://volumio.org/forum/volumio-orange-boards-t9692.html) - script for updating playback cover to display [volumio-album-art.sh](https://gist.githubusercontent.com/aenniw/c74958f8e9ed7f8642c15de98bf57881/raw/af12328ba6fb72c83a895d1201522e03ceb5c825/volumio-album-art.sh) -
