Got a wounderful little headless radio going at home now, and felt like I just had to get a pair of Cambridge Audio Minx Min 11's:
They're tiny, but with tremendous sound.
Want to take the software for a headless spin? Download the binaries and mplayer.exe and unpack to same folder. Then it's just to run AidBand.exe. Press [F4] to start playing your favorites playlist, for instance.
Currently only Swedish public service radio is supported, but it's a piece of cake to add more. You simply add a (publicly available) streaming mpeg URL to a text file. Done.
The source code is available on github. Some 700 lines, packed with stuff like a remote telnet-style control, various playlists, using Spotify artist search for filling your playlists, using Microsoft Speech to let you know what's going on, building .exe a file, etc. Go crazy!
