Step 2: Opening

Step 3: Wiring, Soldering and Closing

This was easy, just grab some thin wires and solder them at the usb pinout, better would be solder them directly on chip but i was too lazy for that.

Edit: Added usb wiring, if you have cable with some weird colors use multimeter. ;)

Step 4: Finish

Now just close it, add some hot glue and use heat shrink tube for finalize.

looks very cool. well done.
Having said that, I bought a small adapter that takes USB sticks and 2 sizes of SD cards and plugs into my phone for 1.99.
For that price it is hard to beat :-)

could you post a link for this?

diy_bloke (author)kariswg12015-05-02

This is the one. plugs in a phone with micro USB, takes USB stick, microSD and miniSD (or is mini SD the regular size nowadays? i kinda lost track).

diy_bloke (author)kariswg12015-04-28

bought it at 'Action' a local thriftstore

Added wiring scheme and picture how ugly it looks without heat shrink tube. :)

The reason it won't work is because USB needs power and that port won't supply power to make it run as far as I know

And whats your point ? Every mobile phone which support usb host has 5v output on USB. ;)

As far as i know, you need to enable usb host mode before connecring something...that means that has to be a pre-wire into OTG/HOST mode.

Work's like a charm on Samsun galaxy note 2, no needs for additional wiring

tfarris (author)2015-04-28

Just to let you all know this won't work I have a better way of doing this without the need of soldering the device I use is USB port on both sides like connecting a USB to the wire without soldering sad to say I plug it into a android and it don't see the drive other wise I would have a 32GB port

This is just direct otg usb and believe me or not it works well.

Great idea, but this could use a little more, step by step, detailed written instructions, for those of us who are more technically challenged.

I will cut the heat shrink tube and open that again to update the lastest steps. ;)

Add a keyring and its perfect.

awesome could definitely be useful, maybe shorting the wire a bit might be a upgrade. maybe remove entirely.

Yeah, you can definitely solder micro usb cable directly on flash drive, but i had only this short usb otg.

So cool! I'm sure this comes in handy instead of needing an adapter. Thanks for sharing and congratulations on your first instructable!
