All in one digital music player/streamer

Here is a project going around in my mind... It will most probably never go anywhere beyond that, but here are notes and thoughts.

The goal would be to build an integrated all-in-one music player/streamer with plenty of features, but still relatively simple and with a low cost.

WORK IN PROGRESS (MAYBE)

Features

  • Plug-in speakers, plug-in media storage, plug-in power, play music
  • Small footprint
  • Hi-Fi component look with volume control and IR remote capability
