[Q] diy connectors - Asus Eee Pad Transformer Prime

I saw a pin out and link to the male and female dock connectors in the orig transformer q&a section. I am thinking about what I can do with them. Some ideas:
1) make a small adaptor from the dock connector to micro USB.
- I understand that charging is slow when connected to a regular USB charger, but I already have like ten of those around the house and in the car for our phones.
2) create an audio/charge only converter from the Asus connector to the iPod connector. I have a speaker that has an iPod dock, and friends/relatives have other accessories for iPods.
- I was thinking of cannibalizing an "ipod dock extension" cable, and connecting one of these mouser plugs.
3) make a cradle or dock, and include the dock connector. I don't plan on buying the keyboard for a while, so this might be a good way to make something out of wood, that lets me charge the tablet, while being able to keep it visible.
I just ordered my tp, so I was wondering what you thought would be useful and what I don't understand.

What is going on with the cables???

Hey guys, i am hoping i missed something really stupid.
But i just bought a few accessories for my TP2.
I bought an extra charger, and an extra USB connection for my Cradle, and an official HTC car charger
All marked as being for the TP2
But they have a standard Mini-USB connection on them, not the wierd little cut off corner connection that is on the underside of my TP2
wht the hell have i forgotten?
is there an adapter i need to buy or summin?
I am thoroughly confused
Thanks for any help

No they will work fine, for Data and Power transfer normasl mini-usb cables work fine, you only need the EXT-USB connector (the cut off one) for video and sound transfer (headphones etc.)
Excellent,
Thankyou very much
It' s kind of strange, isn't it. But all mini usb connectors will fit.

30pin "L" shaped connector?

I will be using my GT 7.7 allot in the car and likely in the landscape orientation. This puts the 30pin connector and cable sticking straight out the side.
Is there any 90 degree ("L" shaped) 30pin connectors available? (similar to a "L" shaped SATA connectors -see picture-)
If there is, this would point the cable towards the dashboard and and make the cable routing less messy looking.
I searched but didn't come up with anything.
Note: I know I could use the Samsung OEM car dock (which, I think, has the power cable connector in the back/bottom) but was looking for a lower cost option.
Thank
Any luck with finding one of these cables?

Have you had a look at my cheap solution for car a car dock and cable management yet?
I know this was posted awhile ago, but if you or anyone else is interested, the original samsung galaxy tab HDMI dock uses the same connector and works w/ the 7.7 (I know because i have a couple). You can get these on amazon for $15 right now. I believe this is the same dock for all the tabs and they just change the plastic piece that holds your tablet to accomodate the model (i have the original galaxy tab, the 7 Plus, and the 7.7 and they ALL work).
If you take it apart, the tablet connector looks exactly like what you are looking for - an L shaped 30-pin. The profile when plugged in is very thin and looks less like when you have the actual car charger cable plugged directly into the tablet.
I've attached a picture of what the cable end looks like. The nice thing is if you keep all the electronics intact, there is an area in the back that the car charger cable connects to pass power to this cable as well as a 3.5 jack for your auxiliary audio connector. Once you lop off the plastic tablet holder part, you have a bare ribbon cable that you can cover in black electrical tape and you just have to mount the pod onto the back of a hard tablet mount and plug your power and auxiliary audio cable into it.
Dear rEVOLVE
i liked your idea the most and i already ordered the dock, but i have a question, my ordered dock has HDMI output as well, so can i do some electronic modification Like this DIY USB OTG cable to connect USB hub to it in the same time as well, so finally i got i charging 30pin port, auxiliary 3.5 audio port, HDMI port, and USB port???
thank you

Anyone ever see extmicro usb to usb a cables

Trying to find out if there is such a thing as going from extmicro usb that the evo and flyer have to a usb type A (or any other normal usb).
Need a right angle to plug into tablet for car install and found that I can fit a microb angled cable into the tablet, but now need to take the car charges extusb and get an adapter to hook it all together.
You can just buy a regular micro USB extended cable. It fits in the flyer/view charge port.
Proprietary cable is the one on the right. Regular micro USB on left.
I am installing the tablet in dash of a car.
I have the oem car charger because its only one with right voltage. But I need a angled usb for clearance issues. So im trying to figure a way to go from the charger EXTMICRO usb to the angled usb.
Searched around and have come up completely empty.
I'm working on the same project and found this thread searching (again) for more info on extusb. The solution I came up with for getting enough clearance to use the port requires disassembly and if you plan on keeping the warranty, it's probably not a good option for you.
Anyway, my solution was to make some small right-angle brackets for the pcb that contains the extusb port. It requires material for the angle brackets and two small screws with nuts. See attached for a better idea.
I actually got the tablet installed and fairly well, but have since removed it to come up with better designs for charging, access to the power button (and possibly volume buttons) for recovery actions, turning the screen on/off with ignition, and potentially microphone relocation.
You may want to check out http://www.dealextreme.com/ for right-angle and other adapters if you don't want to open up the tablet.
PS: Protect that screen. The plastic is very soft and will easily scratch.
I don't follow.
I thought the HTC car charger was a plug with a USB port in it just like all the others. I thought this might help, but I probably have no idea what you're really looking for
http://www.amazon.com/Cables-Go-Right-Angled-Micro/dp/B005EV2LAM
If you *need* to use the 12pin micro usb that the view has (which from my understanding was only there for the docking station utility), then you might be out of luck unless you can build something yourself.
Im looking for a cable like you linked to, but then I need a way to connect the flyers car charger special usb tip into it. Only way I can think of is to carefully grind the corners so that it will fit into a micro B female connection.
But the chargers are not cheap and if I F*** it up Im out $30
On a kia soul forum where others are planning on doing the same install with the flyer, one guy has come accross a company that makes custom cables. He said that if We send the car charger to them they will replace the usb tip with a micro B 90 degree angle for $25.
So A person is sending the charger to them to have it done and is going to let us know how it comes out.
jacobbones, can you provide a link to the kia soul flyer thread?
Yes, here it is.
http://www.soulhamsters.com/forum/i...ale-again-24feb-7-android-tablet-199-shipped/
Talk about the custom job is near the end of the posts
opening up the car charger and replacing the cable is incredibly simple. I have done it so many times, I can probably do it blindfolded. I actually had to go and replace the OEM chargers cable with the USB cable that it came with because my damn dog chewed threw the charger cable. Didn't come back very pretty, but it works, that charger has got the be the best charger built I have ever seen, incredibly difficult to open, but I'm sure the car charger is a lot easier to open, you just need a soldering gun and it should be easy.

Extension cable for MHL Adapter?

I have a MHL Adapter and I get video just fine. Now I want to be able to sit on my couch while i use the adapter. Seems to me the simplest way would be to use a 15-20 foot Micro USB Male - Micro USB Female extension cable.
Does anyone have any experience with such a setup? Do you have a recommendation for such a cable?
TIA!!
Why micro USB? You can get a HDMI cable as long as you might want (Monoprice is particularly good). If it's not enough you can carry a HDMI signal over a single or (simpler to find) two CAT5 cables w/ RJ45 jacks for hundreds of feet.
I guess the thought was that if I have the Micro USB Extension, then it's one thin lightweight wire that has to travel across the floor.
If I did HDMI, I'd still have to be near power whereas with Micro USB, I could set the power adapter, and HDMI, and MHL Adapter all together and then have a thin and lightweight wire traveling across the floor.
But if it's not possible, (micro USB limitiation??) then HDMI it would have to be.

If the micro USB works it would be much cheaper than a comparable length hdmi cord.

I would test http://www.amazon.com/Extender-over-CAT5E-CAT6-connection/dp/B003L14ZTC this. It's hard to get cheaper than cat5e.
Just bought 10 feet on amazon! Lovely!

I wanted to do exactly this - extend the cable but at the micro-USB end to avoid having the Micro-usb power supply line and the bulky MHL adaptor all where the phone is - much cleaner to just have a thin cable coming out of the phone and headed towards the TV.
I did get hold of a micro-USB extension cable (2m/6ft) but unfortunately it does not work. Directly plugging the phone into the MHL adaptor works perfectly, as soon as I insert the micro-USB extension it doesn't work. I need to have a closer look to check the pins are populated etc, but not sure why this would be an issue - don't think it can be signal strength and if all the pins are populated I don't see why the adaptor would care.????
Any thoughts?
Micro B USB extension not working
I, too have been trying to figure out why an extension cable doesn't work the way you think it might. Today, I tried cutting my 6 foot cable, first making sure I had the right power leads working. Then I went through all the possible combinations of connections to see if one would work. None do. I'm at a complete loss on this wondering what I should try next.
Thanks for info....similarly baffled but at least you have ruled out something!
Like the other guy said, get your x for of hdmi cable, then just plug your AC charger in where you are. Mhl might use additional connectors/pins/whatever vs micro USB. Or you can go totally wireless and use a Bluetooth mouse and keyboard.
Also I remember I had a charging issue with an extension. Sometimes one product works better than others. I can't charge my phone with my 20 dollar AC charger from best buy since the ICS leak. It's weird. Hdmi cables are pretty uniform, I would just extend that.

Yes, that works, always has, but that's not the point. Would rather have just one long cable connected to the phone in front of the TV rather than three cables, the device and the phone in a kludge setup.
A partial answer
This allows connecting 6 feet away with a thin, flexible single cable..Also cheap, but shipping takes 15 days.

I took apart the two cables and the USB has four wires while the MHL cable has ten.
are the mhl wires easily extendable themselves by splicing? I'm thinking strip out a few usb cables and use the wires? Or just go purchase some extremely thin gauge wire (22 gauge) and make it yourself?
Micro B USB extension not working
The Micro B USB connector only has 5 connections, so there is no way you can connect 10 from the MHL cable to it, so something else is going on.

I bought splices and thought about extending the cable. It's possible.
galaxy s3
I did wanted to do the same but the extension cable didn't work. I looked at the connecting points and felt that the micro usb from Mel adaptor is to bit longer than usual so I thought that may be the reason and I shorten it resulting damaging my Mel adaptor itself. Now I am going for allshare cast wireless hub. So everyone please don't try to cut the micro usb pin from your adaptor or u will better decide to for my option to for complete flexibility.
I want to do this EXACT same thing but slightly more extreme:
I want an MHL adapter with 10-25 feet of micro USB cable on the end so I can use it from anywhere in my living room.
Is there any such cable/adapter?
Why do all MHL adapters come with only a 5 inch cable??? It is maddening!
*bump* I am looking for this too.. but I have a reason slightly different.. I have an AppRadio in my car that I connect my phone to. The MHL cable end is rather bulky and does not fit into the opening of my otterbox that is on my phone... most microUSB wires fit into the opening just fine.. Taking my phone out of the case every time I am in the car is rather ridiculous so I bought the micro USB extension (bought a 6" one).. didn;t even register except to charge... So, and ideas would be greatly appreciated..

Get a different MHL adapter. I use an adapter close to the one 7 posts up by hedaleth with my kenwood system in my truck.

40 pin cable!!

First off I'd to say hello from Alaska,
Ok this may sound strange but does anybody out there know where i might find or have one made, I'm looking for a cable with 2 40 pin connectors on both ends, 1 male and the other female. This is for my TF201 and dock, I would use it so I don't have to take off the case to the Prime just plug in to the prime and to the dock..
Thank you all Stan
Cables to Go should be able to do this for you. I've had them make custom cables for me before. It likely won't be cheap, but they should be able to do it.
www.cablestogo.com
Just in case anyone was curious, I thought I would try to get lucky and see if a female-female USB adapter with a standard ASUS 40-pin cable on either end would work. However, it was only a novel attempt and the tablet does not recognize the dock as I had hoped.
I am sure Cables-to-Go could get something to work, but I agree that it will be quite expensive. It would be nice if there was a jumper cable accessory to accomplish this same concept since I am in the same position as the OP and typically carry the tablet in its own case and only use the dock when I have alot of typing to do.
On a side note, I did confirm that my Logitech Anywhere Mouse with the Unifying Receiver does work 100% with my tablet and Dock!....I just may be able to leave the laptop at the office yet!
Does anyone have a mapping of the pins and wires? I would like to try and "splice" two cables together to try and make a jumper cable but would need to make sure that I make the right connections. Any assistance would be greatly appreciated.
I don't think that's going to work for several reasons.
First and foremost, if use two TP USB cables as the souce of the parts, you'll end up with a "jumper" cable with male connectors at both ends. You need male to female, remember?
Secondarily (and almost as important) is the number of contacts on the USB end of the cable. USB has four conductors plus shield and nine conductors plus shield in USB 3. Taking a cursory glance at USB plug on my TP cable, that's all there is. I don't see any additional conductors.
Following this, it's EXCEEDINGLY unlikely that the cable has 40 wires (one for each pin on the Prime end) running the full length. If it did, where would they connect to on the USB plug? Kinda silly to include extra copper to go nowhere.
Instead, if you were to pry open the 40 pin male plug, you'll see that most the pins aren't connected to anything. They're not needed for the USB cable.
Sorry to say, this just isn't going to work.
If you do choose to clip one of your cables just to have a look-see, cut the cable somewhere in the middle. If you cut right up next to the USB plug, you won't have ample wire there to repair what you're about to break.
I am aware that you will need a female adapter to make a true "jumper" cable. However, there may be a way of jerry-rigging a connection to the dock if a female connector can't be found (I have yet to find a part online).
My question is more in regards to whether or not anyone had a schematic of which of the pins are connected to which of the respective USB pins so that I could determine the best way of making a connection....short of having a cable for the ASUS TF201 like this: iPhone Extension Cable
