Can I have an N-Mosfet controlled by one power source to control a separate power source. I want to have power from a USB port to control wether power is going to a fan and water cooling pump, and to leave the power on for some time after the computer is turned off. It simulates ok, but simulations are not always real life.
Any other notes are appreciated.
Below is an image of the circuit. The lower left corner from the ADC on is only for testing. A simulatable version is at Falstad, but I had to remove the timer.
