USB female connector free!

I decided while making a Xbox USB adapter that I didn't want to waste my money on a USB extension cable that I would eventually cut apart for the USB female port. So I looked up some information on USB and spent many minutes staring into the different ports on my computer, and decided that it theoretically I would be able to make a USB male into a USB female.

WARNING:
I am not responsible for any damage or injuries to you, your stuff, or anything else that might happen from this instructable. This shouldn't be dangerous but if your that dumb, now you can't sue me!

ALSO VERY IMPORTANT
It was brought to my attention that if this was plugged in upside down, it would short stuff out and that's bad! So don't do that!

Thanks for the tip maltfalc!

Step 1: Cut Stuff Up!!

I used the USB cable from my old iPod but I expect it should work fine with any other cable.

Materials
-USB Cable
-Small Flat Head Screw Driver
-Scissors/ Knife
-Ultra thin pen or other small poking instrument

First, cut the cable off for whatever length you need (It will be easier to work with).
On the Apple cable there is a small crack where the two halves of the case are glued together all the way around the connector, jam the screw driver in carefully and pry the halves apart to reveal the metal inner case.

first time you accidently plug this in upside down say goodbye to your motherboard or power supply.
Rossiroller (author) in reply to maltfalcNov 30, 2008. 8:37 AM
That doesn't make sense. Unless there is a charge or anything going through the metal case around the connectors, which I'm 99.9% sure is not true, it wouldn't do anything.
maltfalc in reply to RossirollerNov 30, 2008. 4:16 PM
one of the four metal strips on the female connector will be at 5 volts. plug something in upside down and all four metal strips are shorted together through the metal case around the male connector. same thing happens if anything metallic brushes against the female connector. shorting out your power supply is a bad idea.
Rossiroller (author) in reply to maltfalcOct 5, 2009. 1:46 PM
Alright you've got me, I surrender. JK Now I understand, although I won't be using this again, I'll add a warning specifically about that to the instructable. Thanks
cornflaker in reply to RossirollerJan 16, 2009. 6:02 AM
Is there any metal on the back of the new connector? it's only plastic with the contacts on one side right? If so then hes wrong and you should quickly unsurrender lol
maltfalc in reply to cornflakerJan 16, 2009. 6:42 AM
you have four contacts on one side of the new connector. one of those contacts is being fed five volts from your computer's power supply and one of them is grounded. if you attach it to a male usb connector upside down, the metal piece surrounding the male connector comes in contact with all four contacts, shorting them together and burning out your motherboard or power supply. same thing happens if the connector brushes against your house keys, any exposed metal on your computer case, etc.. anyone still having trouble understanding why shorting this thing out is a bad thing should avoid using anything electrical for everyone's safety.
deeveeoeedee in reply to maltfalcApr 9, 2009. 3:47 PM
it wouldnt short out your motherboard or power supply, have you ever put you key in the usb port before? you get an onscreen error saying that the port surge, click reset to re-enable the port
skrasher in reply to deeveeoeedeeApr 5, 2011. 1:40 PM
actually it CAN short out your power supply, 100%. I've been in IT for a while, seen faulty cords do it a number of times. Once I had a user with a bad cord, and they killed three power supplies and various computers....so yes, it can for sure happen.
cornflaker in reply to deeveeoeedeeApr 10, 2009. 3:28 AM
Yes we all go sticking keys in our USB ports... lol
snowpenguin in reply to maltfalcMar 3, 2009. 6:13 PM
Just because someone doesn't understand if you are talking about male or female doesn't make them unfit to use or build electronics.
Rossiroller (author) in reply to snowpenguinMar 9, 2009. 8:26 PM
No you definitely shouldn't. If you didn't know the difference between a rifle and a shotgun I wouldn't want you touching guns let alone modifying them.
snowpenguin in reply to RossirollerMar 10, 2009. 7:39 AM
We aren't talking about guns, now are we?
Rossiroller (author) in reply to snowpenguinMar 15, 2009. 7:38 PM
And a serious electric shock can't kill you as effectively as as gun?
cornflaker in reply to RossirollerMar 17, 2009. 5:13 AM
Yeah snow penguin is right there the 5v coming out wont do alot - you wont even feel it...
snowpenguin in reply to RossirollerMar 15, 2009. 11:18 PM
There isn't that much voltage in a PC, for one. Two, no one is stupid enough to point a gun at themselves, and three, what does it matter if its one gun or another? If you are a beginner you are going to have to learn the difference, but you don't necessarily need to know the difference. When you first start out, your instructor-guy will hand you a gun and eventually have you shoot it. You don't need to know what type of gun it is to know how to shoot it and the dangers involved. We were also never talking about modifying guns, as that would be completely irrational and highly more dangerous than peeling a metal case from a USB connector. So, in your opinion, somebody can't touch a USB connector if they don't know how it works? Does that mean people won't be able to use their iPods anymore either? I'm glad you're not President, because a country run by you would limit the use of electronics to people who understand what is going on inside.
cornflaker in reply to snowpenguinMar 10, 2009. 5:20 PM
Its been a while since I've read this so I forgot what I was talking about and whether I thought Rossiroller was right or wrong, but I believe that the gun analogy is very good
snowpenguin in reply to cornflakerMar 10, 2009. 8:17 PM
No, I don't think so. We are talking about a simple misunderstanding of female and male connectors. That is not the Rossiroller's fault, but maltfalc's for not making a clearer argument. Also, we are simply talking about 5 volts, not a bullet from a gun. That analogy is really just taking it a bit too far. There is no imminent danger to anybody if this shorts unless they are touching the actual power supply or something critical like that. Also maltfalc is being a little bit unrealistic... maltfalc says: "anyone still having trouble understanding why shorting this thing out is a bad thing should avoid using anything electrical for everyone's safety." They should avoid using anything electrical? That's just bad. Many people who use electronics have no idea at all what is going on inside them. They may not even know what a volt is, or if it is bad to touch positive and negative together. Just because somebody can't tell what somebody else is getting at, be it either of their faults, doesn't mean they are unfit to USE electronics. Maybe they have only explored simple stuff, like a battery and an LED, but haven't got into more complicated things such as USB. You have to think about how people will interpret your words before you say them, or at least correct your mistake afterwards.
cornflaker in reply to snowpenguinMar 12, 2009. 3:25 AM
Well I don't agree entirely with the first comment about touching anything electrical at all, but there is a pretty good chance that someone who doesn't know what their doing could destroy at least part of their computer by attempting this. And while this isn't going to kill someone most analogies are greatly exaggerated to make a point more obvious.
maltfalc in reply to snowpenguinMar 11, 2009. 12:02 AM
i've explained the problem as clearly and simply as possible in 3 seperate replies so far. if you short out a computer's power supply, especially an older, lint filled one, not only are you risking killing your computer, you're risking starting an electrical fire. short circuits=bad. anybody who can't grasp a concept as simple as that should not be messing around with anything electrical until they have some idea of what they're doing.
snowpenguin in reply to maltfalcMar 15, 2009. 11:25 PM
You haven't explained it clearly at all. People are just mixing up which is male and which is female, and what goes into what. If you want people to understand and want to be able to make remarks like you did before: "anyone still having trouble understanding why shorting this thing out is a bad thing should avoid using anything electrical for everyone's safety." and still back it up, you need to explain things better.
cornflaker in reply to maltfalcMar 12, 2009. 3:30 AM
I just read the whole thing again and now I understand that I indeed was wrong before and that if you put this in upside down then it WILL short out, so yeah be careful
snowpenguin in reply to maltfalcMar 11, 2009. 7:04 AM
Are you actually reading the comments, or just replying to them? I wrote that you weren't making clear enough sense at first for people to understand what you were talking about. I have no problem understanding why shorts are bad; I don't need you to tell me repeatedly, thanks. All I'm saying is you are treating the people who don't understand like idiots just because you yourself aren't making clear enough sense. The fact that you need to post 3 comments saying the same thing is an indicator that you need to make more sense.
cornflaker in reply to snowpenguinMar 15, 2009. 3:50 AM
That was meant for maltfalc right?
snowpenguin in reply to cornflakerMar 15, 2009. 11:09 PM
Yeah.
cornflaker in reply to snowpenguinMar 17, 2009. 5:01 AM
Ok, cause I think you accidentally replied to me lol
snowpenguin in reply to cornflakerMar 17, 2009. 9:50 AM
I think I replied to myself who replied to maltfalc.
cornflaker in reply to snowpenguinMar 21, 2009. 12:01 AM
haha lol maybe instructabes was just "having a moment"
cornflaker in reply to maltfalcJan 18, 2009. 1:56 AM
Wait is the new connector connected to the computer or the perhipial? Because if only the contacts on the perhipial are being shorted then it its ok, but yeah if the contacts connected to the computer are shorted then... *Zzaaaapp!!... Bye bye!* Oh but it wont destroy your powersupply, just your motherboard or maybe even only the USB controller on it.
maltfalc in reply to cornflakerJan 18, 2009. 8:21 AM
it's a female connector, so you'd be plugging peripherals into it. i've had a frayed usb cable kill a power supply before when it shorted out, but everything between this connector and the computer's power cord is at risk of burning out. whatever overheats fastest from the extra current dies first.
cornflaker in reply to maltfalcMar 12, 2009. 3:27 AM
Really it went all the way to the powersupply? How old was the computer? You would think that there would be some kind of protection to stop it damaging anything else...

Dude, you can't plug this thing in upside down. Its impossible, the metal contacts are only present on 1 side of the plug. The metal casing around the "plug" is merely for structural support, not for electricity, therefore if you plug the thing in upside down, nothing will happen.. -jamnoopers
Rossiroller (author) in reply to jamnoopersDec 23, 2008. 10:30 PM
Excuse me, did you just miss that whole explanation? The case is metal, so when all four pins touch the same metal surface they short and you get messed up. "one of the four metal strips on the female connector will be at 5 volts. plug something in upside down and all four metal strips are shorted together through the metal case around the male connector. same thing happens if anything metallic brushes against the female connector. shorting out your power supply is a bad idea." -maltfalc

vomov says: Mar 15, 2010. 4:03 AM
I've tried the screwdriver, but it wouldn't get under the connectors. So I tried to work with a bit of solder, but it became 'too thick' to fit in the other usb plugs. So I did something else: I removed the top edges of the plastic element where the connectors were on top of, and used a small bit of tape to thicken the bottom. Now it fits with enough friction to stay put, and the connectors make contact! :D
Rossiroller (author) in reply to vomovMar 15, 2010. 7:43 AM
 Awesome! mind if i add that on to the instructable?
vomov in reply to RossirollerMar 15, 2010. 3:14 PM
If it works for other people, that would be awesome! Add away!
vomov says: Mar 13, 2010. 2:14 AM
I've tried this with a solar powered usb charger (which only offered male usb connectors), but it does not have the holes underneath, so I can't push the connectors out... Ideas?
Rossiroller (author) in reply to vomovMar 14, 2010. 3:01 PM
 i guess you could try to drill through from the bottom with a small dremel like tool.... or, i would try using a very small flat head screwdriver to try to wedge under them and pull them up. or you could try to melt a little solder on them to raise them.  the main point is to get them higher than the surrounding plastic so they can make a connection
Wesley666 says: May 24, 2009. 4:11 PM
Aren't USB plugs the same? They both have the metal square and the four pin connector inside, one is plugged in upside down into the other. Wouldn't this make them Gay or asexual so you can't give it a sex change.
Rossiroller (author) in reply to Wesley666May 27, 2009. 11:44 AM
If you look at a USB plug on your computer, you will notice that instead of pointing out, its more like a hole. The plug that goes into the hole sticks out. The popular terms used for all connectors are male and female. A male plug sticks into a female plug much like a human function that they are very similar to. It is true, that essentially the insides are the same, thus why this works. But the casing is different, therefore male and female. The purpose of this instructable is to change a male plug into a female plug, thus the slightly humorous title of "Sex Change".
Wesley666 in reply to RossirollerMay 27, 2009. 3:28 PM
Ya, your right the plugs are slightly different. I never really looked that close at it.

Works great! I just did it with an old Foxconn cord. The procedure was a little bit more messy though than yours since all the wires were coated in some sort of rubber or silicon.

hi, good and simple instructable, i had just a question : i want to make an extension cord for a USB concentrator (that litle think that makes 4 ports when you have 1) , but my problem is HOW to connect the wires to avoid make a short and say goodbye to my thinks. in your diagram the cables must go blue, red, black and green...but in the opposite side goes exactly backwards, is this correct ? can anybodie help me (with some photos if can be possible) and tellme how to connect this things correctly ? i will use 2 male connectors on each end of the cable . any help will be so well received. thanks in advance to any that lend me a hand
bowser. says: Jul 4, 2008. 7:46 PM
does this change what wires you need to solder when combining with your xbox male cord?
Rossiroller (author) in reply to bowser.Jul 6, 2008. 5:27 PM
It shouldn't. I just followed the same directions when I made mine and it worked fine.

triggernum5 says: Apr 8, 2008. 5:09 PM
Now I feel like an idiot.. I've wasted time salvaging ports from old motherboards, and made my own connector pads from credit cards and pop cans, each time chopping off a good male connector.. I guess an actual female port yields a sturdier connection.. I like a weak breakaway for homade male connectors that plug into the xbox controllers breakaway connection..
NTARelix says: Mar 25, 2008. 7:57 PM
This helps me a lot. All I have for extra USB cables around here have male connectors on both ends for some reason...

great idea +1!
bhunter736 says: Feb 28, 2008. 7:39 AM
This is too simple. I love it! I need an extesion too, not enough to buy one, so I will be doing this later today. It seems like every device I get comes with a new cable, so there are lots of those to play with. You know, it occurs to me you have effectively shown how to make a unisex connector. You can still probably use this as a male if you are careful with insertion. Very good idea.
Rossiroller (author) in reply to bhunter736Feb 28, 2008. 5:39 PM
FYI there are some things you need to look into for making an extension because if it's too long without a repeater it won't work well. But, should still work fine as long as you keep the length down to a moderate amount.
