Few years ago, I bought original Raspberry Pi, planning to use it for internet radio project. Unfortunately after initial trials it became clear that built in DAC is unfit for listening to music. Project was shelved for some time. Then Raspberry Pi Zero fall into my hands and I decided to utilize it, resurrecting that old project. At that point I was a happy user of Chromecast Audio, so utility factor was somewhat reduced, but I decided to build it anyway. Just because I can!
Entire device is built on single mother board, which contains:
1) WM8731 audio codec
2) ENC28J60 Ethernet controller
3) connectors for RPi0 GPIO header and SPI LCD screen
4) IR receiver for remote control
5) Two tact switches and rotary encoder
Music Player Daemon is the main piece of software, responsible for the audio playback - hence the name "eMPeDocles". :)
Device can be controlled from standard Android MPD client. Basic playback control functions are also available by buttons and enco
