Hey guys, wondered if anyone fancied helping a guy out. I have a cabinet set up with 6 raspberry pi's and one full pc motherboard. The full pc I shut-down and is really an "on demand" server for my VM's. I have been using WOL and pm-hibernate to wake up and shut-down the pc (the on-board network wont wake the pc from powered off) and just recently when using pm-hibernate I havent been able to wake it up unless using the button.
I would like to use one of the raspberry's to power on the pc using the gpio pins. After looking around and doing some research, everyone is saying to use an optoisiolator. Now, just to be clear, my electronics knowledge is no where near anything good, I can get by without blowing anything up, but I am still a noob and still learning. I understand what an optoisolator is, why i should be using one, and how one works. Saying that, in my mind I see a transistor as a viable solution, and I have a few different types to hand, where the optoisolators I dont......
Now does anybody mind telling me
a) If i can use a transisitor instead..
b) if not, why not??
c) if I can, are any of the transistors I have any good for what I want??
I have 2n2222 IRF44Z BC547 BC327 and IRF3205.
Many thanks in advance
