Bill Serasidis posted in his website a really nice arduino webradio circuit, which actually connects to winamp.com for fetching the data and decodes the stream through a vs1053b module. From the schematic I can see that is not too complicate to build and I really like the way he put parts together.
The parts list:
- Arduino pro mini
- ENC28J60 ethernet module
- VS1053B sound module for decoding
- Nokia lcd
- Simple switch for station selection
So why not transforming that old boombox you still have in the closet? Have a look here
