By default, pin 4 on the micro USB head is unused which provides a device peripheral connection when plugged into a host (e.g. PC or Mac).

To enable OTG mode on the micro USB head, short pins 4 and 5 to ground (black wire).

Once OTG is enabled, the micro USB head now acts as the host and a standard female USB head on the other end will be able to receive device peripherals.

- Generic micro USB cable
- USB extender

Tools
- leatherman skeletool cx
- mastercraft folding blade
- modeling tweezers and tape
- mastercraft soldering station
- rosin core electrical solder
- electrical tape
- modeling cement

1. Slice open micro USB head

Just what everyone needs, a flaky cable that might do nasty things if it gets put together wrong or falls apart at an inopportune moment. Seriously, they're $5.

These are all tools and material I've owned for years.

And who really wants to wait - if ur competent and skilled why not do it urself?

Just saying it's a great tutorial and all but it's easier to just order one. Mine only took 3 days to get from an ebay seller.

Mine was only $1.99 on ebay with free shipping :)

I found it easier to cut my cable and short the wires, then tape it up. I also cut it down to only a few inches. Thanks anyway OP.

Used to shoddy craftsmanship? Unable to create?

Everyones opinion differs and the satisfaction I get from creating my own OTG cable won't compare to buying it even if only for 2 or 5 bucks.

But hey, we can agree to disagree right?

You dont understand what me asking the benefit of an OTG cable vs a regular one? I dont get why anyone would do this or buy it. I must be missing something.

In short, the OTG cable allows u to plug in peripherals (mouse, Kb, flash drive) directly into the note and it will be able to host the attached USB device.

Dearest Brother,

i wish you had said this in the begining of the thread.

it would have saved you those nasty adrenaline chemicals from spilling around in your body and giving you anxiety and a pounding heart, whilst reading through the comments.

as you may know, the wolves will bite.

cheers ;)

    Thanks. I just made one for myself too. And screw everyone who are complaining that it's cheaper to buy one. I had all the neccessary equipment right at home and got it way faster than some ebay ****.
