I want to build a device that will interface with a computer via USB or RS232 that will power a different computer on or off. I'm envisioning the device having a lead that will connect directly to the power leads on the target computer's motherboard, and a USB/serial cable heading to the "controller" computer's USB/serial port.
I know there are a million retail solultions out there -- I won't bore you with the details, but none of them work for me. I need to build one.
My question is simple: can anyone point me to readily available electronic components that would allow me to build this? Again, I don't want a packaged retail solution. I want the actual electronic components.
Thanks in advance.
