I got a new phone which is Samsung Galaxy on 7 and it has very less memory. So I decided to buy a OTG pen drive which cost me 500 rupees. But I have lots of pendrive. Now they are not of any use. So I decided to buy a OTG cable. It also cost me hundred bucks. So I decided to make my own OTG pen drive from my old one.

Step 2: Step 2: Schetematic Diagram
Step 3: Step 3: Preparing the Micro USB
There are 5 pins in micro USB 2 pins are on one side and 3 pins are on another site. I assigned the pin numbers in the diagram. you can find it on Google also. And there are 4 pins on USB male port. We have to connect pin 4 with 5. The picture micro USB has the pin numbered, 1 is red 5 volt, 2 is green data-, 3 is white data +, 4 is USB OTG ID, 5 is black ground. The picture male USB has the pin numbered, 1 is red 5 volt, 2 is green data -, 3 is white data +, and 4 is black ground.
Step 4: Step 4: Preparing Pen Drive
Open the outer shell of the pendrive. Just be there be careful. You can damage the pendrive if you are not in precaution mode.
Step 5: Step 5: Wiring
It is very simple to wire up. Just go through the schematic diagram. And you will be able to get your own on the go OTG pendrive. Place all the components inside the shell of the pendrive and wrap it with some electrical tape. In my case I used velpore hypoallergenic and latex free surgical paper tape.

These are the previews of how it will be look like. Now it's time to check whether it is working or not.
Step 7: Step 7: Testing
In the first pic when I didn't inserted the OTG pendrive its showing device storage and SD card. In the second image when I inserted the OTG pen drive its showing device storage, SD card and USB storage A. USB storage A stands for OTG pen drive first. You can see in image third when I open storage settings its showing USB OTG storage which is of 4 GB. Can use more than 4 GB it's totally depends on you.

Why should we remember this OTG cable if we have an personal OTG pen drive which we can carry anywhere. Here we are carrying OTG cable along with a pen drive now we have our own OTG pen drive so we don't need it.
