I have used Nicecast to do this before, with acceptable results: http://www.rogueamoeba.com/nicecast/ Unfortunately the link would only be one direction, from the PC to the router, not vice versa. I have no idea if the USB speaker will work, it depends on the chipset used and whether it is supported by OpenWrt. The only adapter I have tested is the SYBA adapter I link to in the tutorial. I have no experience with other USB-audio adapters. Jeff kabukicho2001 -

And if you may send one email for another consultation.

Would be even better if you learned that "it's" should not be spelled with an apostrophe, except when you mean "it is." Nice series of articles.

The minor incovenient is that it comes without case. And i have a question ¿do you know another usb sound adapters?, i wish to know if conceptronic usb sound adapter (CSOUNDU) works on openwrt. http://www.conceptronic.net/site/images/produkten/CSOUNDU/CSOUNDU_prodpicZm_1.jpg thanks Now i think there is a more suitable patform, the nanostation routerstation (50 € aprox.)

I'm not sure wether espeak will fit into the internal flash, but I'll try it. Any contribution will be welcomed. Buddy, about the speech output:

One thing that's kept me from a streaming Internet radio (besides the price) is that they're woefully inaccessible to blind users...so I've been interested in a project like this. I'd like to see controlling it with a USB numeric keypad and having speech output (say, using espeak). And I like my WL-520GU so much, I do think I'll buy one just to play with for this project. Router+USB sound dongle+USB hub, I already have a numeric keypad. Nice project, although I think I’ll forego the serial port (I’m all thumbs).

I was just about to buy the router and audio interface from newegg, to build my own, but the tiny $8 interface adds $7 to the shipping, which convinced me to look for cheaper options. Any idea if this will work: http://www.dealextreme.com/details.dx/sku.9723 ? The description make it look almost the same, but I can't find the chipset anywhere. If anyone is interested, DX has a slightly more expensive one with a volume control, and the same chipset as the newegg one: http://www.dealextreme.com/details.dx/sku.8978 But I'd rather go cheap if possible :) Wow, thanks for posting this!

The post was getting long so I decided to break OpenWrt into part 4, but this should get you started. To complete this project you'll need soldering skills and some level of comfort hacking around with Linux and/or a willingness to learn. I can't promise you won't have to write a line of code but I plan to post everything I create for this so you can at least use my work as a starting point. Foo -

Question: Am I going to be able to copy your project from an experience point of view? I am fairly handy at soldering, modify equipment physically doesn't scare me, but rewriting code or coming up with my own, not so much. If I can make the electronics connections, will you have source code to download? Also, hurry up and get part 3 up! My router and usb wil be here from newegg tomorrow! :) BTW, router is down to $26 with rebate.

It will run on Linux or OS X (although it's more painful on the Mac). I've been able to port a couple simple programs although I am not an expert by far - I found that almost everything I needed was already included as an addon package to the main OpenWRT distribution. <a href="http://www.openwrt.org" rel="nofollow">OpenWRT</a> Z –

I've never quite been able to get one setup well enough to compile applications, and I want the exact same thing you do, a cheap streaming radio bridge for my garage. You might also want to look at a Sondingo unit, geeks.com had whitelabel versions from C-Media, the OEM, for sale, and they've got audio outs built right in.

I added the serial port so I could see the stock firmware boot messages, watch the reflash process status, and eventually I'll be using it to connect an LCD display and the rest of the user interface. It's also really nice to have a reliable terminal that doesn't rely on proper network configuration. Craig/Chris - I'm planning to add an LCD display and a tuning control. A webserver for configuration would be great. At a minimum, mpd (the linux music player I am planning to use) supports many clients, including the iphone, for network control. “Me” – sorry I missed your comment earlier.
