I have a computer connected to a router. The computer can do wake on lan, but you can only set it for one date at a time. That's fairly useless if I just want it to power on on weekdays. I'm not going into the BIOS every night and setting it for the next day.
Instead I want to use a Raspberry Pi. Or at least that's what I'm really leaning toward. I haven't come up with a better idea, short of having an entirely separate computer

I haven't bought a Raspberry Pi. Everything sounds very doable. I'm looking for suggestions, ideas, advice, etc. with this thread.
The setup:
Computer connected to...
router... out to isp
Then I'll add a Raspberry Pi to the router via ethernet. Everything here is wired, no wireless.
The Raspberry Pi will act like an alarm clock to fire off a wake on lan signal whenever I want it to. I'll have it set for weekdays 6am and 5pm to power my computer on. Then my computer will do its wake up stuff and be ready when I get to it. (Yes, I'm that freaking lazy and impatient. But willing to pay a little and work a little to automate this. I'm doing the same thing daily, letting a few minutes of my life slip by each day while I'm waiting on the computer. I'm not buying a new computer either. I just want to add this on to what I've got.)
I'd need a Raspberry Pi, ethernet cable, some kind of cover/box for the Pi... And then I'll need a little batch file, run by a chron job I understand, to run somethign to fire off a magic packet or wake on lan signal. I'm familiar with Windows and batch files. I've installed Ubuntu and looked around at it a bit, but I'm not really a Linux user. That's my background. I found one post about this online but not many details. Most people want to use a RP to get around their router and send a wake on lan packet from the internet to their computer. I want to use the Pi as a tacked on alarm clock, no internet/router messing needed at all. And I'm lazy -- I don't want to send the wake command from work and I want the computer on before I even wake up each morning.
Any thoughts?
I need to...
Check for sure that my computer will wake via magic packet or some kind of packet. That will shoot the whole little project down. I'm pretty sure it will though.
I need a Raspberry Pi and case. I thought there was only one RP, but I'm not quite sure.
I need to know how to create a batch file on Raspbian (?), how to set that to a chron job, etc.... Need to know what app or whatever is available to send a magic packet or wake on lan signal in Raspbian....
I also want to stick Ubuntu (or something, maybe Raspbian in some way?) on an extra laptop I can borrow and test this out with a borrowed laptop before I even buy a Raspberry Pi. That way I'll know the batch file works and it's just a matter of actually setting up a Raspberry Pi to do the same thing.
