Since a while I was puzzling my mind on how to remotely turn on my PC.
I've come across a few solutions online, none of which is applicable
or really useful, especially in my case.

Eg:
- infrared remote control (short distance)
- "wake on LAN" technology (non working with wireless LANs)

I have small wireless LAN of linux clients and servers, I travel a lot
and I use to manage most of the computers remotely.

Yesterday I decided to build a small device that is able to do the
trick. I will use a mobile telephone with a new SIM card and new
number. The telephone will be phisically connected to the computer
motherboard. I'm planning to mod the telephone PCB to switch on one of
the PCs when the telephone is called.

I still have no blueprint and before starting the project I'd love to
have your opinions/ideas about it. I think it can be a very useful
little device for many people.

- which of the telephone's circuits can be used to power on the PC
(the speaker circuit maybe)?
- is it possible to build a small bypass between the real PC switch
and the motherboard?
- how would you build this or improve my idea?

That's a commonly used technique and there are devices called
"paging data receivers" which will do the job properly instead of
hacking a mobile phone.

Google "paging data receiver" for hundreds of thousands of hits.
