unfortunately i dont have access to calipers, far as i can measure outside thickness is about 3/4 maybe slightly less, inside thickness is about 1/8 inches. sorry i cant be more accurate.

im assuming you want to throw a USB on the PCB? im not exactly sure how you want to connect that usb female connector, or what the purpose would be to do so.... Mind explaining just a little more?
[Asus  Eee Pad Transformer Prime] e.mote:
Mount: Use dremel to create a rectangular hole (12.5mm x 5.2mm) at the back (or front) of the dongle. Use a short-body USB connector w/ right-angle contact like the previous, and mount it orthogonally, eg perpendicular to dongle facing. I think the short-body one has a length of about 0.5" so it should flush-mount. But if not, having it sticking out a bit isn't a big deal.

Purpose: To charge tablet w/ either 12V@1.5A or 5V@2A. I would go with the second, since USB car chargers for it are widely available (that's what the iPad uses).
[Asus  Eee Pad Transformer Prime] robertg9:
I know that the PC USB charge @~500ma takes forever and the TP has to be shut off, but what would the deal be with 5v@2A

Would I be able to continue to use it as it charged, or would it need to be shut down too.

I'd probably use a USB 3 connector in place of the pictured USB 2

Thanks for the idea...I never thought of that....now all I got to do is to wait till I get my dongle.

[Asus  Eee Pad Transformer Prime] pileot:
ahh! makes sense.... sure would be nice if we had a full connector port. Maybe i could make a trip to an electronic component store and pick up some USB connectors.

If you just want to use it for power then dont we just need any sort of connection to the charging ports and the outside of the dongle? It doesnt have to be USB it could be anything as long as you have a male and female connection
[Asus  Eee Pad Transformer Prime] robertg9:
There is a neat tool in Google Play called Smart Tools. Possibly you could get better measurements of the items you want to measure by using the tool, and laying the item right on the screen. I have it installed, and think it was a well done app.

No idea. That's something you can find out afterward. Having the mod in place won't hurt anything.

My guess is that it should be good enough to at least maintain battery level while on, which would be all that's needed in a car.

>It doesnt have to be USB it could be anything as long as you have a male and female connection.

You can use barrel power connector. But you'd have to make your own power cable, as opposed to using a standard USB cable to connect to the charger. Edit: On second thought, you can use a 12V@1.5A car charger, then get a mating barrel connector.

[Asus  Eee Pad Transformer Prime] pileot:
from what i understand if you have the tablet on and try to charge with 5v it wont even maintain the current battery level. The tablet charges with 15v or something... having a barrel connector would ensure you dont accidentally plug a prime charger into another USB device frying it.
[Asus  Eee Pad Transformer Prime] BSMan1011:
At that point if we could just get the barrel plug right to the power pins, fitting it in should be too hard....I am really interested iin this because I have 2 dongles coming tomorrow annd planned on hacking one....(I got two because one was RMA and they sent me a new one back 2 serials=2 Dongles)
[Asus  Eee Pad Transformer Prime] pileot:
See edited first post. Because the top row does not go to the back of the PCB and i believe thats where the power is, it would be hard to throw a charging circut in there. I am still working on locating where all the pins in this thing go but it is very tiny, even with my finest nodes to test these circuts its very delicate work.

In the mean time, i will upload what i do have before i go to sleep tonight (maybe in another hour or so) so stay tuned!
[Asus  Eee Pad Transformer Prime] BSMan1011:
Okay I will try and keep updated... if we could get a charging circiut in maybe a true car mount might be a project... at least for me, I already have a tablet window mount and with some changes I could affix a modified dongle at the bottom and just slide prime in for GPS + charging (again if we can get it to work)... I get mine today and disassembly will soon follow so I will post anything else I can to help progress
[Asus  Eee Pad Transformer Prime] BSMan1011:
Okay first off...have we all decided to stay low until we progress, i don't want this thread to die so soon...secondly...though I am sure you have done you research I still must ask, Are you sure? if we can provide any charge to the prime it will at least help a bit...also does anyone one else have other ideas other than charging?...

one idea I literally just thought of so it is not very thought out is, what if we remove the dongle case( as we have done) and integrate it into case.... we will need one of the 40-pin cables to wire onto it but maybe it could fit into some cases.

I will continue to try to think of more uses and mods and will update, meanwhile I hope that we can get some more input
[Asus  Eee Pad Transformer Prime] buxtahuda:
Hmm, you've made quite a bit of progress there. I really wish I wasn't lazy haha, I need to learn to really work with electrical stuff.

So, then the dongle uses some of the pins that would be used for power from the dock? If the dock can pass power without changing the Prime, I should think the dongle could somehow. I mean, only certain pins are used for data right, so the dock and dongle should use the same ones?
[Asus  Eee Pad Transformer Prime] pileot:
Ok, firstly. Yes, im sure. Im sure of the pin placement and based on the best available information scattered around the internet, i know which pins the charger uses and i know where they are located on the dongle. I also know there is very little access to them (as seen in the pictures in OP)

as to integrating the dongle INSIDE the prime casing you would, essentially, be succoming to the same problem the internal antennas have: Metal blocking the signal. Sure its a more powerfull antenna however its encased in PLASTIC not metal, the signal it recieves is a lot stronger and there is less EMI caused by the metalic back plate. Short: Yes you can, no you dont want to.

Finally, the pins the prime uses to draw power are different than the pins the charger uses to supply power. Think one lane dirt road vs a 6 lane highway. On the highway you have dedicated lanes for traffic going in different directions. this is similar to how the prime dock connector works, the prime can turn off power to different connections depending if there is something plugged in reducing the chance of a short, spark, or power drain.

Hopefully this addressed your concerns, maybe when i have apropriate tools handy and a bit of time i may try soldering a connection to the dock connector and see how it functions but as you can see its REALLY tight. I will do my best, no promises.

I also plan, in the near future, to locate more of the data pins, see whats going on, maybe we can make a USB adapter for the dongle and use it in other devices as well! who knows, im thinking it just uses a standard USB interface but it will take more digging.
[Asus  Eee Pad Transformer Prime] copc:
Subscribed as I see no need for the dongle unless you have enough power.
[Asus  Eee Pad Transformer Prime] BSMan1011:
Though I was pretty sure you were sure I just wanted to ask.... but you did misinterpret my idea, I do not mean the Prime's casing but rather integrating the gps into a case which holds the prime...This is not to say that the gps is big or in the way but just an idea i had to help people with cases and a use for the gps, but since the usb uses different pins that looks unlikely as well i guess...well I will stay updated and if I learn anything I will post.
[Asus  Eee Pad Transformer Prime] copc:
I would be more interested in adding a power jack of some sort to the dongle. So you can charge while using navigation. I already can not use my dock while plugged into the dongle. We need power!
[Asus  Eee Pad Transformer Prime] pileot:
Ahhhhhh, thanks for clearing that up i was misunderstanding you. Yes, it definately would be possible to integrate this dongle into one of those flip leather type cases. Once you remove the guts from the GPS dongle its really relitively small, given enough play you could have it inserted in the case and still have it close properly.

Sorry for the confusion.

Copc unless you can solder connections in less than 1mm of space (i know i lack this skill) i dont think its possible. I mean im sure theres SOMEONE out there that can add a power connection but look at the first post and you can see why it would be extremely difficult to solder onto such a small area.
[Asus  Eee Pad Transformer Prime] e.mote:
I think to play inside toys nowaday, sooner or later you'd need to learn SMT soldering. The below is the best video tutorial I've found. Get some practice on a cheap MP3 player beforehand.

[YOUTUBE]3NN7UGWYmBY[/YOUTUBE]

An easier (and more functional) alternative is to ditch the dongle altogether, and use a BT GPS receiver. No mod needed.

Yet another alternative is to mod an external GPS patch antenna for the built-in GPS receiver. You would want to use a female MCX bulkhead connector, like this, so nothing sticks out from the shell. MCX connector is small enough to be used, and robust enough for repeated insertions.

[Asus  Eee Pad Transformer Prime] pileot:
wow that video was actually really helpful, maybe i will attempt to soldier the connection after all, just to see how it works.

As to adding an external antenna to the prime, most of us dont want to do that, if anything some kind of bridge adapter (male to female 40 pin connector) that we could plug the dongle in with and then plug the whole thing into the prime and splice power into the adapter might be a better solution? should cost around $15 in parts (im guessing around $5 per connector) and maybe a few bucks for the power adapter you decide to use and some shrink tube to keep it all together.

Anyways, thanks for the vid and i'll have to try it later. I will be sure to post the results when im done!

wifi maybe?

I've been following this thread because I also have an extra dongle coming due to having returned first prime over poor pic quality, and I have a friend who is a genius at electronics.

Many people have wifi problems. My replacement isn't as strong as the first. If this can function as GPS antenna, why not wifi booster
[Asus  Eee Pad Transformer Prime] BSMan1011:
The other idea that people would die for, though I will say right now is probably impossible or at least not worth the massive amount of time and risk required is to add a WIFI antenna to the Dongle...though like i said this is unlikely....power is one of my favorites right now but as we are stuck I am just trying to continue movement of hacking the dongle
[Asus  Eee Pad Transformer Prime] pileot:
Ok, today i was actually using the GPS and i had a thought....

What if we took the antenna (largest chip on the thing) and desoldered it from the dongle and soldered it doirectly onto the sisterboard where the pogo pin connects INSIDE the prime? there SHOULD be just enough room.... I mean ya there would be problems with interference but a better antenna might just overcome those... what do you think?

As to the wifi hack.... Not sure how to do that, basically you would have to program the prime to look for an external wifi antenna through the dock connector then add the hardwre inside the dongle.... In its current state i dont see that happening however i would LOVE this kind of mod, i would rather a very strong wifi over craptastic GPS any day

One last thing that MIGHT be helpful: We COULD find pins on the dock connector that are not used as of now and send a lead from the pogo pin on the wifi antenna down to the dock, then use the dock connection on the bottom to put an external antenna into the dongle, there is more than enough room.

We could have it far enough away from the prime to avoid interference from the metal back AND theres no hack n slash drilling through the prime itself. This is another mod i may attempt in the near future. whaddya think?
[Asus  Eee Pad Transformer Prime] BSMan1011:
That is the exact same thing I was thinking of...the wiring to pogo pin.... but I personally would never want to do it to my prime, but I did think of that as a way of doing it, I would love to have someone try it and hopefully have it work but it will not be me as I would have a hard time risking my Primes life like that

...but other than that, or hacking the software to detect it, which is far beyond me

>add wifi to dongle

GPS is occasional-use; wifi is always-use. Putting wifi in dongle means it needs to be attached all the time. How would you use the dock? Do you want it to eat power continuously? Do you really want such an ugly wart on your sleek Prime all the time?

There is no easy way to boost Prime's wifi. A permanent external attachment is impractical for many reasons. If you want it bad enough, you need to go all-in: Drill a 1.5" hole in the upper-middle back, put a patch antenna there ala iPad 1, and cover it with a tweeter grill. You can make two holes for both wifi and built-in GPS, obviating the dongle.
[Asus  Eee Pad Transformer Prime] pileot:
The problem with drilling holes is its a much more "hardcore" mod than most would wish to do. I personally dont want to drill holes in the case of my prime. My wifi works well enough for most uses however having the ability to plug in an external antenna when i need that boost would be a plus.

Also, having an external antenna through a dongle would mean there is no need to always have it connected. When your just playing games or watching movies you dont always have that hole in the back of the tablet.

Additionally, if the connection was wired to an unused port on the dock that would mean there would be no interference in using the keyboard. Its all in how its wired and what pins you use.

For those of you interested in cutting holes in your prime have a look at the "opened my prime" thread, lots of good info there.
[Asus  Eee Pad Transformer Prime] e.mote:
>The problem with drilling holes is its a much more "hardcore" mod than most would wish to do...My wifi works well enough...

What's hardcore is relative. Patching power through the 40-pin port is more dangerous to your Prime than drilling a hole, and is a harder mod. If we're talking about aesthetics, then having 2" tweeter grills on your tablet is a lot easier on the eyes than the plastic dongle blob--or, heaven forbid, having rubberduck ants attached via RP-SMA connectors.

Whatever you want to do, at some point you just need to do it. Too many people just talk and don't do anything. The hardest part to modding is taking the first step.

If you want to use the dongle as housing for ext ant, then find an unused pin and solder it to the ant lead. Regardless, modding the dongle means soldering fine-pitch leads (which sounds pretty hardcore to me). So get the power mod done and worry about whatever else later.

>Additionally, if the connection was wired to an unused port on the dock that would mean there would be no interference in using the keyboard.

So you'd have the dongle attached to the dock attached to the Prime. Have you actually visualized what a huge kludge this would look like, and what it requires?

>Its all in how its wired and what pins you use.

Yes, exactly. And you would find this out by...how?

I really hope you are seriously considering using your gps for the 13 hours you will be on 95 south. or I-81/85 if ur heading west.
[Asus  Eee Pad Transformer Prime] rosebud:
If you want an external wifi antenna, whats to stop us removing the asus logo off the back of the unit, cutting down metal in the same shape dremmeling little holes in the void where the logo goes and wiring the newly cut asus logo to the pogo pin? you could then enamel coat the metal and there you have it.. an external antenna with a stock look??

[Asus  Eee Pad Transformer Prime] pileot:
problem with that is the whole aluminum case gives off so much electromagnetic noise that any antenna within about half an inch of it is basically useless. Even if you did that (amazing idea, by the way) you would likely see very little improvment because theres more to the problem than just that.
[Asus  Eee Pad Transformer Prime] rosebud:
Fair enough, what though, if we added a layer of shielding behind the "logo"..

-------------------- <<metal asus logo

-------------------- << Adhesive

--------------------<< shielding

--------------------<<more adhesive

-------/\-----------<< prime with hole

I'm personally not having any 'real' problem with wifi, so just putting the idea out there :)
[Asus  Eee Pad Transformer Prime] pileot:
there was someone in the "opened my prime" thread that was going to layer some 3m em shielding to see if there were any improvments in signal reception with less noise, never heard back from him. I think im going to carry on with my GPS antenna where the pogopin antenna is, see if that does anything for me. Will post results if i get any!
[Asus  Eee Pad Transformer Prime] scrufy:
Hey guys,

I've been reading this thread. Lots of cool ideas here. Not a lot to contribute but this:

If your going to do the remote power in mod in some way add a couple safeguards so you don't accidentally blow up your stuff.

Put a tranzorb or bi directional zener across the power inputs for reverse polarity protection and add a small signal diode in series with the power lead.

These things will both be kind of sacrificial in case anything happens in the future.

Just a good idea to incorporate it into your design depending on where you tap your power.
[Asus  Eee Pad Transformer Prime] Bumble-Bee:
Has anyone looked at mounting the GPS extension PCB within the kb dock :/
[Asus  Eee Pad Transformer Prime] bourne-nolonger:
Hey, very cool thread.

Most of this is WAY over my head, but I have found it very interesting nonetheless.

I do not own a prime, but I am in the market for a tablet and have been considering the prime.

I was wondering, for those who have removed the backing, is there an improvement in the wireless/GPS signal by just removing the backing?

If there is, would it be possible to fabricate a new backing for the device? Or maybe a better question would be, would a new backing not made of metal correct the issue?
[Asus  Eee Pad Transformer Prime] buxtahuda:
The problem is you don't really "remove the backing," so much as "remove the screen." All the components other than the screen and its Gorilla Glass (plus all three of our antenna) are attached to the backplate.

Yes, using your own antenna, and keeping it about 1/4-1/2 inch away from the aluminum casing results in much better signal reception. Yes, you may could fashion a new backplate, but that's going to be pretty difficult to do whether you modify the existing one or create one from scratch. It'll involve safely disconnecting and replacing all the major hardware in the Prime.
[Asus  Eee Pad Transformer Prime] bourne-nolonger:
I see what your saying. I figured that it was probably a lot more involved then seemed - otherwise I am sure a lot of people would be doing that.

I just thought I would ask and get it cleared up for my own personal curiosity. Thank you for clearing it and sharing you knowledge!

Think I'm going to wait for the tf700 :D

The One X with it's dedicated image processor, called Image Sense, can shoot photos while recording full HD videos.

It shoots 720p slow-mo super smoothly. And very slow.

It can also take pic after pic, (like the spies) quicker than one can blink their eye's.

It's all scratch proof, YouTube HTC one X scratch test.

That's just a few things I have managed to figure out.
[HTC One X] stm2008:
In terms of speed, S3 must be faster than One X on benchmark result.

However, I like the build of One X more than stylish then S3.

For the battery life issue, companion core in T3 saves a lot of battery in standby mode. I don't know if such feature also available in S3 (maybe no, so the battery capacity is larger?!). However, when you are actually using HOX, the battery drains quite fast.

What I don't like S3 for another reason is AMOLED, even S3 got a 4.8" screen, PPI is smaller than S2! Also, the color tone is cool and it easily get screen burns!

I don't like HOX:

1) Power button design

2) Quite hot after using it for a while

3) USB goes to the left
