Intro: Power Switch for USB Devices
This guide will show you my version of a switch for a USB hard disk. I did this as i wanted to connect an external hard disk to my router, but did not want to leave it on all the time as I just need it 2, maybe 3 times a week.
Of course you can just unplug it, but in my case and since it is in a narrow space, i prefer to have a switch to do it.
(You will need some basic soldering skills to build this)
- 1 picture: These are the parts you will need
You can use this, or any other switch you like, its easily found on ebay, as well as the USB male and female connectors.
I wanted to keep it simple so i'm only going to use the switch to cut the 5V supply and not the data pins or ground since they don't work without the 5V.
- 2 Picture: First thing I did was to cut down the pins a bit, so that they don't stand out that much, this is just for aesthetics.
- 3 picture: I used some cooper wire in order to hold the USB connector in place.
- 4 picture: And soldered some wire to the other 3 pins.
- 5 picture: Measuring how long the wires should be
- 7 picture: At this point everything is soldered in place and i wanted to superglue the connectors to the case to give it stability, but then i had a better idea
I soldered the case of the male to the case of the female USB connector to give it the stability i needed. With 2 copper wires, one on each side. That way you can pull on it, without it falling apart.
At this point my thought was to make it look a bit nicer with some FIMO or something similar which you can mold and then make it become hard. I wanted to use it all around so you cant see the wires, but then i just figured out that where I would use it, it would not be visible, so i just let it be like it is.
The final picture is the place its actually serving its duty.
