Power On Your PC using your Cell Phone

Power On Your PC using your Cell Phone
As you all already know, nowadays we can acces our home PC remotely over the Internet. But what we do if we are away from home and our PC is not powered on, and also there is nobody left home to do that for us?
As I consider myself being a geek, I keep my old stuff, and also collect used and partially broken stuff.
Many of us changed often the mobile phone or cell phone... whatever you call it. I have a Nokia 1100 with it's microphone broken. So I tought it can be useful for something in the future.
I used only recovered parts for this project!

P.S. Sorry for poor photo quality... were made using another... mobile phone. :D

Oh wow, nice work. Btw, hope you just realized you have discovered not just how to turn on a PC, but also how some insurgents are setting up their remote IEDs (Improvised Explosive Devices). But of course, many things can have a duel purpose, so great to see a good practice use of such ghetto tech.
