How to make a USB OTG adapter for connecting peripherals on the phone - video tutorial

Hi friends, in today's tutorial will teach you to make your own USB OTG adapter for connecting various USB peripherals to your phone (mouse, keyboard, USB stick, joystick).
USB OTG (on the go) is a more special adapter that allows us to connect all sorts of peripherals to a smartphone, I tried with several devices, some of these peripherals were connected others do not, those who wanted to work are part of devices that need a lot of energy and of course the phone is not able to provide too much energy.
What peripherals were connected via USB OTG:
Wired Mouse
Microsoft Wireless Mouse
Microsoft Keyboard
Keyboard no name
USB Stick
Memory card (the reader)
What was not connected to the phone via USB OTG:
Condenser microphone (Samson C01U)
Portable hard disk (2,5 ″, 7200 rpm)
Why we need to build our USB OTG adapter?
1. Micro usb or mini usb cable, plug the phone depends on some tablets have mini usb micro usb but most telefonelor have.
2. Mother jack USB cable is a kind of extension to jack higher than normal, it can get a USB stick.
3. Tools for cutting, gluing insulating Sibanda.
4. Gun or soldering iron and modified loop like in tutorial, so you can do soldering in tight spaces.
5. Pasta wire strippers and soldering tin.
6. OTG USB compatible phone, not all telefonele supports it.
7. Patience and attention.
Careful:
While micro or mini usb socket unscrew have to be very careful, you can cut or scratch easily, so be careful.
How does USB OTG adapter cable?
For we only need two adapter plugs, plug micro usb plug usb and mother.
The first step is cutting and pasting cable, micro usb plug wires will connect to the USB jack mother, job is simple, respecting restore cable color code, we need to get out a cable with micro usb connector on one side and the other side of the USB mom .
The second step is the dissolution of micro usb plug, this must unite wire with lug megru goal in micro USB socket for this deck can use some thread. Splice must do it carefully because it contacts the other wires are very close to each other.
The image below can be of great help while you plunge, need to keep in mind its a micro USB socket contacts are not like in the picture, the socket will find two contacts on one side and three on the other side. We will have to bring a thread from the black (on the three contacts) to lug contact which has no seam, it is on the other side of the connector (on the two contacts).
We expect the comments section to tell me what you did.

  • Very good tutorial, I gave 50 lei on a cable of its kind and is very useful. I use to smatphone my Samsung Galaxy S III and it does its job very well. Just like you Cristi no I am not worked an external HDD. I hope to make as many related tutorials and Android phones, for me I attract more tutorials about phones. I use the phone more than take it with me everywhere, while they use the PC a few hours when I get home.

  • USB OTG adapter is very good, but not all phones (smatphone) supports OTG function.
    I tried and had some surprises.

  • marius:
    With this type of cable can connect the modem 3G?

    Why would you want to use or connect a 3G modem to a smartphone when you can nicely remove the SIM from the 3G modem and insert it into the smartphone, make the configuration settings for the internet and voila ... will complicate ...

  • Adrian Gudus: Why would you want to use to connect a modem or a smartphone 3G nice when you can to remove the SIM card from the modem 3G and inserts into the smartphone, you configure settings for internet and voila ... High will love to complicate ...


    The SIM card with internet voice and did not.

  • On sony ericsson x10i - android 2.3.3 and on lg optimus l7 p700 - android 4.0.3 it doesn't work or I don't stick the black thread to the free slipper ... I'll buy one to see if it works ... interesting anyway!

  • Hello, always at the height. Please you can also make a tutorial where we download books in Romanian for phones. Thankyou

    Here I have an answer, probably the phone is coded only on a certain network. For example, I tried to take the card from the 3G modem (DigiNetMobil) but I have the phone coded on Vodafone and I can't make connections. :)
