Hey All,

I don't know if this is the right place to ask for help about this but I'll just explain and introduce first and then we'll see about that later.

I've been a very happy Padfone 2 owner and user for about 3 months right now and have been following, reading and using a lot of all the great work, you all have been doing over here on XDA. @ walaway thanks for making this thread! I still think this is a wonderful device but since the beginning I've just been really bummed that they didn't make a keyboard dock for this device like they've done for the Padfone 1.

So I got the idea to try and change an existing Asus Keyboard dock to work with the Padfone 2.

I think that the Tf101 keyboard dock is to bulky, The TF300 Keyboard dock apparently has some kind of nut

tomshardware. com/reviews/transformer-pad-tf300t-tegra-3-benchmark-review,3179-7.html

that make it hard to put it back together again after dis-assembly. which the TF201 Keyboard dock doesn't have according to these two video's

youtube. com/watch?v=4DB8qLeOIlk&context=C3685d3eADOEgsToPDskJlt8NwBaN2HzVQ3YNXaD9o

So I figured that from this point on that the obstacle's would be

1 replacing the 40pin connector for a 13pin MHL one.

2 finding a solution for the latch that keeps the two together and

3 maybe a software related part that lets the Padfone 2 Recognize the KeyDock

for the possible software part any help woudl be helpfull but I'll figure that out when that problem arises, and I'll be spending my summer break on getting to learn Java/Android programming & and will try to get some of the TF201 software that has to do with the dock, to work on the Padfone2.

I'll just take the Latch"hooks" that would need to go into the tablet part out since I'm not (yet) willing to open up my padfone station and don't have a clever idea yet how to fix that. or make it so that they will stay together (any suggestions on this part are more then welcome)

for the changing of the connector part. I figure it's just making sure you connect the right wires and make sure that the voltages and currents are transformed to the correct level.

so that means that I'll need to figure out the pinout for both the 40pin asus connector that goes with all there TF models and the first gen Padfone, aswell as the pinout for the 13 pint mhl connector for the Padfone2.

for the 40 Pin Connector I've found these Threads

Sinds the inside of the plug is compatible with/identical to a micro usb plug I think its safe to say that this pins will be the same as the pins for a micro USB plug, which can be found here

en.wikipedia. org/wiki/Universal_Serial_Bus

So I was wondering if anyone knew how to figure out the other pinouts of the 13 pin Padfone2 MHL connector. and if any one had any idea's or suggetions for this project.

I'm a physics major, so I've access to a lot of measurement tools so if DMM's and scopes or something else is needed that probably won't be a problem

I bought myself a second hand TF201 dock that will be arriving in a week or so, I only need to get a Padfone 2 charging or HDMI cable so I can use that to salvage the connector.

and when and if I get things to work, I'll write a nice tutorial for those who are interested.

ps. yes I know that buying a BTkeyboard would have been cheaper and easier but I just like the extra battery, card reader &USB port that come with the asus keyboard dock.
