[MOD] microUSB to Tab dock adapter (one of a kind!)

I finally received my spare Tab usb cable and a few microUSB SMD sockets and have successfully hacked them together to make a very portable adapter so that all of my existing microUSB cables work on the Tab as well. No more having to carry a different cable with me!

Nice work. How did you mount the female micro so neatly?

A video of it functioning would be awesome. I am interested in making this as well. I actually want to create a full USB adapter. I know there is a schematic of the cable and what each one does. Its just a matter of wiring it up right. Perhaps you can make a how-to? what if you plug a USB thumb drive using a USB to micro USB adapter. Would that work?
From the Tab.

I don't know if it would do anything with a thumb drive or anything else that requires a host port. For a microUSB socket, there are 5 pins, of which 1 is unused when you wire it to a regular usb dock connector like this one. I haven't looked at the pinout posted, but it's possible that 5th connection is to toggle/enable host mode on the Tab. If I get a chance I'll plug in an external drive and see what happens.
As to how I shoehorned the micro socket into the dock port connector, it just required an X-acto knife and some super glue. Soldering on those tiny smd pins is a pain, so if I make another, I'll etch a small pcb and mount it that way.

Great work! Do you have any pictures of the inside of the adapter?

Unfortunately no. I will take pics of the inside of my next project, which is to make a dock connector adapter that'll break out into a microUSB port alongside of a miniHDMI (kind of how Samsung should've done it to begin with). I'll definitely snap some pics then, and post up the Eagle files if anyone's interested.
EDIT: Looking at the pinout thread, it looks like the HDMI dock has all sorts of stuff in there that I had assumed were inside the Tab. I'll probably make another microUSB adapter so I can prototype the pcbs.
EDIT2: For USB On-The-Go, it looks like the unused pin 4 (ID) just needs to be grounded to pin 5. I'll test that too.

Wow, this looks great. Have you thought about making a few spares and offering them up for sale? I would definitely be interested. Let me know

I'm currently trying to track down a supplier of the 30-pin connectors. Seems a very daunting task at this point, since I can't speak Chinese, and the majority of the component suppliers do. It wouldn't be cost-effective to purchase full usb cables with the connectors just to harvest the connector off of them. Also, to even test the OTG functionality would require a dock connector with all the pins (or at least pin 13 + the usb ones); most of the usb charging/sync cables only have 7 of the 30 pins. The only connector I know of that has pin 13 is from the HDMI dock, and that's an expensive way to test.
So once these connectors are more readily available, I'll look into making a batch.

[Q] Where?: S PLUS tutorial to soldering usb charger connector?

I'm having problems with usb charger connector of my Galaxy S Plus
I just bought two connector from ebay, but I can see pins are very small.
Where can a find a tutorial about soldering usb charger connector?
Thank you in advance (And sorry my limited english).

DIRECT connection for wireless charging

Hello guys,
Few weeks ago i read about connecting standard wireless qi usb adapter to phone itself. I mean, connect 2 stripes of cables to 5v and ground on motherboard, so usb would be still avaiable. Do you know where on motherboard those pins are ?

Interesting, I'm trying to find out too. I did a mod that way with my NOTE1. Mostly likely near the USB port, but I afraid it'll affect the NFC , because NFC is on the Cover. And the coil 's pcb must be extremely thin.

I would gladly get rid off nfc anyway, as I don't use it. Voltometer is on its way to me, so any time soon I'll try to update the thread

news pliz??
thanks..

Can wireless charging be used when case is still on the phone?

current Qi is good for 7mm i believe...which is plenty of space for most cases. it wont pass through metal though, and I'm sure some materials hinder that more than others. I used a couple different cases on my nexus 5 and was able to charge with all of them.

The Qi chargers are 12V I believe. I modified a car charger to fit the adapter for the Qi wire. I had to solder it to the 12V wires in the car plug. The 5V would not charge it.
You should be able to find 12V power coming out of the power supply.

USB-c cable that fits with Official Adopted case.

I just bought a Anker USB-C to USB-A cable only to discover that it won't fit with my Nexus 5X when I have the phone in the Google adopted case.
Does anyone know of a USB-C to USB-A cable that has been verified to fit with the Google adopted case? I also have an aukey car charger that came with a cable that fits the phone with the case on but I want to leave that cable with the charger in the car.

I bought this pack of two one long one short and use it with adopted case without any problem so far.

Is there a battery case?

Or a battery that plugs directly into the usb-c port with no cable?
