We are a collective of dancers and bicyclists that organize huge bicycle rallies up and down the west coast. There are dozens of bicycle sound systems on these rides, and we seek to send an airplay audio signal to everyone's smartphone with wifi. The software of choice is Airfoil. http://rogueamoeba.com/airfoil/ For it to send audio, it needs to be installed on a windows or mac computer (not cell phone or tablet). Smart phones can then receive the audio signal. I need help designing a road worthy wifi router and windows machine to be the moving hub of this wifi broadcasting party. Extra points for durability, signal strength and thrift. Please be detailed, because I am only vaguely knowledgeable of wifi, and I'm not that bright. Please note that I am well versed with other options for sending an audio signal. I have reasons for being this specific. Without your help, I would acquire a used netbook with a solid state drive running windows (maybe about $200), grab a wifi router (I have a few older ones lying around) run it all on an inverter and give it a go. Because I am a mac guy, I don't know how to do anything, like how to set up a local area network.... (I usually jam in a cable from a high-speed modem).... we are not doing that on a bicycle, so I'm a bit fuzzy on that part. I am well versed with power supplies, and willing for the range to be less than ideal at first... (that can be improved later) I am just looking to get a trial of this system up and running. I am most appreciative of your help, and I plan on writing a full article on what I've learned, if successful~ Thanks!!! Tor PS, Photo not of me, but these people are obviously awesome, and will love what we are doing.
