Maybe one of you guys can help me. I have several external drives and other equipment that is hooked up to my computer.
When I shut down the PC these devices stay on since they are fed by 120 Volts. The older PC cases used to have a 120 V plug in the back for the monitor and other stuff. So once you turned the PC off, the stuff plugged in would turn off too.
I was thinking if there was a relay or similar that has a signal (low voltage) input taken from the PC i.e. 5 or 12 V. The "high" voltage side would be 120 V.
So when you start the PC the low voltage current from it would give a signal to the relay to switch the 120 Volt on.
Is there something like that out there that can easily be purchased (Radioshack) and be uitilized for my project?
