I'm collaborating with a team of local makers to make a good sized space ship for kids to play in, and we'd like to add a little bit of ambient sound by streaming SomaFM's Mission Control (
http://somafm.com/missioncontrol/) station in some high power speakers. However, we are building everything from scratch, and need to come up with a solution here that streams internet radio (over Wifi) cheaply.
We've thought about Mac Minis and netbooks, but those can cost anywhere from $200 and up. Does anyone have any simpler solutions to bring internet radio to an exhibition space on the cheap?
