Want a Wi-Fi radio that can play just about any audio source and you can control from your smartphone? Here's how to make one.
In the video above, Tinkernut shows us how to take an Asus WL-520GU router and a USB sound card to make a Wi-Fi radio for under $US50. The process described uses Windows, but if you want to use a different OS, you can follow the instructions over at MightyOhm instead. There are a lot of steps, but overall this isn't too difficult a hack. You just take install custom firmware on the router, change and install some files, and set up an application called Ario on your PC. You don't have to use Ario, however. Your choice of MPD client will work just fine, and you can find one for pretty much any OS or smartphone in this listing.
