DIY Energy Saving Socket Strip [Copy link]

When your computer is turned off, the indicator light on the monitor is still on silently, and the speakers are working secretly, making some terrifying crackling interference sounds from time to time.

People with obsessive-compulsive disorder always have to turn off the computer, monitor, and speakers. They must resist these unfriendly designs.
Here, we will bring you a simple and easy-to-use design to liberate people with obsessive-compulsive disorder.

A principle analysis that even a novice can understand: when the computer is turned on or off, the USB port will also be powered on or off (of course, the USB port that the motherboard supports wake-up will not be powered off). Therefore, we can use the signal from the USB port to control the power on and off of the power strip, so as to control the power on and off of the devices connected to the power strip. So easy...

It is clearer with pictures. Here is the schematic diagram. USB controls the relay, and the relay is connected to the socket strip.

The following is to start making it by following the instructions.
Materials:
socket strip (any one is fine, as long as it can fit a relay),
USB cable (any mobile phone charging cable),
relay 220V 10A,
small resistor 10 ohms (mainly to reduce the power consumption of the relay and prevent it from working for a long time and heating up),
perforated board...

Then weld and cut according to the circuit. Short and compact is the best choice.

Come on!!! The 8-yuan power strip with free shipping, open it up, there is enough space inside, it is enough to fit a relay.

Make a hole in the power strip, pass the USB cable through, and connect it to the signal input terminal of the relay;
connect the relay control output terminal in series between the power strip switch and the socket.

Apply hot melt glue and close the lid to complete.

I tried it on the computer, turned it on and off, and it controlled the power of the monitor and speakers perfectly as expected.

It advocates green environmental protection, energy saving and money saving, simple and practical, and a unique design that can relieve obsessive-compulsive disorder.
Hehehe!
