recently i bought a few of those incredible tiny and cheap routers called tplink 703n ( more info ). i started thinking about, what can be done with those devices and came up with the idea of building a small web radio device. package (including readme file with detailed info) Images for 703v1.7

hardware overview:

* cheap usb soundcard is connected to the usb port of the tplink

* old speaker of a mobile is connected to the speaker plug (plus resistor to get 24 Ohm)

* atmel attiny85 (or 45) is connected to the uart of the tplink router

* two potentiometers for tune and volume setting
