"Once the basic idea to build a web radio myself was fixed, I thought about the components to be installed. So initially I also included a Raspberry Pi to discussion. Finally, I have decided on a combination of the TP-Link WR703N router (about which I have already reported several times in my blog) and an Arduino Mega.
This decision had several reasons - first, I had both the router and the Arduino still in my parts box and on the other I wanted to implement the project as cheap as possible and on minimal hardware. Certainly a realization with a Raspberry Pi would have been possible, but this would have been more expensive than the TL-WR703N and the Arduino Mega together. Furthermore the hardware of the Raspberry is almost "oversized" for the project requirements."
