First post so please be gentle!
Here's what I want to do: a) Build an alarm clock that can wake up my desktop (in another room) via WoL b) have the desktop send audio (either from files or from streaming website) back to alarm clock's speakers
I think item (b) would be significantly more complex, since (a) just needs something that can broadcast a magic packet. Therefore, I have two questions: 1) What would it take to achieve (a), i.e. What is the minimal amount of hardware I need to attach to my Arduino UNO in order to be able to send a magic packet? 2) What would I need in order for my desktop to transmit music to the Arduino? I'm guessing some software accommodations to the desktop and some hardware upgrades to (a) are required.
Through searches, I know that several posts have breached this subject before. Few of them seem to find resolution, and the solutions don't seem to involve WoL.
I also found this really neat guide where a guy builds a WiFi internet radio by hacking a cheap router: http://mightyohm.com/blog/2008/10/building-a-wifi-radio-part-1-introduction/ Maybe I could follow his guide and build a clock into it. I honestly have no idea which would be an easier approach.
Any advice/help you can offer would be greatly appreciated!
