The led in the movie can be easily be replaced with the relay behind it to control power to the socket.
Technically I can enter the commands to the com port manually like I am doing here, but I am going to make a server/client for it when done.
I have pictures of the soldered serial port connection I will try to post if I can post images now.
I only need one wire cause I soldered the ready signals together and request/ready together so it is a recieve only circuit. It's the transmit pin.
Movie overview:
Logged onto my linux server from my laptop, sending a command to the com port. Led Lights up and stays on (Equal to power turning on and staying on with relay there).
[end overview]
It's dark so you can see the led, but you can't see the circuitry that well. It's basically a modification off of the "wake on call" circuit I posted instructions to.
(Nope can't add the photos of the Modded com port connector I jacked off of my old PDA connector), I'll zip them and add them later.
I just thought it was cool and wanted to share the movie even if nobody cares,lol.
Edit:
In case you were wondering, whether the command is off or on depends on the pulse length. The Led is hooked to the output so you can't tell but I sent a long pulse.
Edit2:
The pulse length is set by the number of 0 bytes I send. It produces a type of square wave, I use this.
In the movie I use ascii characters, that works too, its a different wave. However I switched to copying a binary out with the 0 byte squarewave (It's not all high because of the stop/parity).
