Standalone WiFi Radio Control Panel (Arduino-Powered)

Picture of Standalone WiFi Radio Control Panel (Arduino-Powered)
I wanted an Internet Radio for a long time, and was delighted to find Tinkernut's Wifi Radio project (http://tinkernut.com/archives/2387 ), which I built and have enjoyed for a few months. 

However, I didn't really care for the Ario based control interface, which required a computer up and running to start, stop, or change the channel.  I wanted to build a stand-alone controller, and found MightyOhm's Wifi Radio (http://mightyohm.com/wifiradio ), on which the Tinkernut project is based.  MightyOhm's control panel looks very nice, but it seemed more involved than I was ready for.  I don't have a non-Arduino AVR programmer, and I wanted to use things I had on hand and avoid opening up my router if possible.  Please note that this is an intermediate project, which will require basic multimeter experimentation to determine how the rotary encoder functions, and intermediate breadboarding, since there are a lot of connections involved.

So, using an Arduino-compatible controller board (Adafruit's Boardiuno , actually), a standard Arduino Ethernet Shield , a 16x2 character LCD, and a rotary encoder knob, I was able to quickly put together a controller that could select and play from a number of preset channels, turn off the radio, and display station, artist, and title information for the currently playing station and song.

If your router has a serial port and runs linux, it might be cheaper to just communicate to it via serial instead of ethernet. You might need to write some code to do that though, but it will definitely be cheaper.

MightyOhm's build did involve opening up the router and hooking up the microcontroller to the serial port, but it involved soldering a header to the router's PCB, which I was hoping to avoid. I know the Arduino + Ethernet shield is a rather pricey route. I would like to use something like this: credit-card sized arduino ethernet controller  which has it all in one, and would be much cheaper, but I haven't been able to make up the PCB for it yet.

I was thinking yesterday, it might be possible to add a USB serial port (with a USB hub), and control it that way.
