Let the hive mind of Engadget get that for you.
"I am looking for a device that will stream sound from one source to several recipients. For example, I want to stream sound from my TV or stereo to my phone or MP3 player that has radio and Bluetooth capabilities. I have looked into radio transmitters and they seem like a decent choice, but I can't find one that uses external power (USB or from the plug) and I would want one with a transmit range of around 50 meters. Thanks!"
I'm right there with you. I've actually wanted to build this too, or at least assemble the parts to make a small multi-component system. And to all those fashionistas who think it ain't pretty, I challenge any of them to build anything better without a factory to back them up. As someone who's hacked together a solution or two, I think it looks great! Seriously, for the space it fills, it appears well engineered. Have you published a parts list? Despite all the negative comments from people whom I won't make any negative comments about, I think this thing's totally cool. I wish I had the time and your ingenuity. Though other folks haven't said so, let me be the first to say thanks for letting us know about your cool creation. I want one.
