I have had enough problems with some computers and I would like them to restart if the device stops emitting power for 30 seconds after it has been turned on. "The first 25 seconds the device does not emit current through the usb, the other 5 seconds of margin, and if the device does not reach current then send the pulse to restart"

Hi, this could be done via simple current detector (it could be resistor + op amp)connected to USB power bus, and will sense it's currents present. I would use a simple Arduino (could be Arduino nano/Uno) to sense this current and then start counting it for 25 seconds/whatever you want. Then for the restart operation we could discuss it later, how, depending on what kind of computer would be used. Let's discuss the details of this project over chat. Best Regards, Rijal
