[GUIDE] DIY [penny size] Micro USB OTG to USB Adapter for more storage.

MicroSD OTG
Mine storage only so I'm soldering a microSD reader straight to a microUSB plug, which lets me make it a little smaller.
I'll solder the reader on backwards as in the photo so it hopefully wraps around the back of the device. Bull i'll fix it in place once I have the N10 and can measure it up etc.
EDIT: Electronics are done, just need to package it now, nice and neat.
See new image attached, connected to my SGS3.
Thanks, can't wait. Draw me a diagram.

@alias_neo, nice. If you're going for soldering method and don't plan to use (female USB for controller, mouse, ect.). There is one even smaller here.
Yeh, I have a few smaller ones myself but none that I wanted to sacrifice to this project. I've not heat-shrink wrapped the wires and will encase the connector properly tonight.
I have the proper microUSB ecasings for the connector, but it's huge and I want to keep it small so i might make one from ... wood? Who knows.
I also like the way you retained the female USB for game controllers, mouse, microSD, ect. I turned the female USB to the side, when plugged-in it's only half the size of the female USB.
Yeah, I considered putting the female usb port at a 90 degree angle, to keep it from sticking out too much, but I realized that would significantly limit the number of devices I could plug into it based on the width of their usb plugs. The one unfortunate thing about my adapter is that the female port is fairly shallow, so whatever you plug into it, tends to stick out an extra 1/8 inch or so. However, a deeper female port probably wouldn't have fit as nicely without using a larger lego brick, so its a reasonable trade-off.
How is it limit the number of devices you can plugged into? It's only half the size of stripped female USB. It's perfect for small profile devices like a phone. The only downside is in depth it's twice the size as your when laying the female USB on it's surface. But the trade off is worth it because you'll be holding your device and you want it to be as small as possible. If you're using a stand, it's even better.
I don't actually have my N10 yet, but this picture using my Galaxy Tab 10.1 should illustrate the problem with the 90 degree design.
As you can see, this thumb drive i significantly fatter than the lego brick. If I had used the 90 degree design, there's no way I would have been able to plug it into the tablet with the thumb drive attached.
Now I plan to mostly use this adapter with really small devices like this:

For that device, the 90 degree design would probably work ok, but I wanted to still have the option of using fatter devices occasionally if the need arises, so I decided not to use the 90 degree layout.

Now, I understand what you meant but that isn't true. The device in the picture is Nexus 7, v.1 and v.2 works perfectly with any USB devices. These was build with a case-on in mind, it will take a thumbdrive.
aaaa
Since we're building for the smallest form factor of storage; Micro USB OTG to USB Adapter. It's only logical to buy the smallest USB microSD and it's only cost a $1.
