Hi all,
I am planning to modify an existing handsfree set for use with my XDA and during planning I found:

On this page you will see the following line:
Anschlussmöglichkeit für externe Antenne

For those that can't understand German: Can support external antenna
How do they do this? I have not found any reference of a connector for an external antenna.

It probably uses a passive coupler. If you place a properly-designed coil very close to the phone antenna it will couple RF effectively.
Your right!
Got the car kit yesterday. Opened the cradle and found a large piece of PCB that is positioned close to the antenna of the XDA. This PCB is connected to the lead that comes from the external antenna.
Francois
Yeah, a passive coupler. Makes sense. It should give you a 3-5dB boost, good enough to clean up conversations in fringe areas.

Sorry,
whats PCB???
Can U make a Photo?
Stevie
PCB = Printed Circuit Board.
A foto would be overkill, just imagine a piece of epoxy 5*5 centimeters, covered with copper.
Francois
Hello FVH,
would be nice to hear your experiences with the car-kit.
Does radio mute work ?
Does the sound work through the radio speakers ?
What is in the box of the car-kit ?
Is it worth the money ?
Thanks :lol:
FVH,
Re the PCB description, is it just as you say "a flat piece of copper" without a pcb design on it, if it does what does it look like... are there any other components on it?
e.g. can we make one up easily!
using sticky back plastic or veroboard - e.g. Blue Peter with a bit of Maplin thrown in to achieve a better xda signal...
So if this thing really is just a flat plate, and has no intrinsic components, pcb tracks or special properties...does it that mean we could just rig up a sheet of tinfoil or other conductive item nearby...
I guess we need a Radio Ham with an xda to tell us we're onto a lost cause - Hopefully owning an xda is not like the early days of broadband, where you have to base your homebuying/renting on where you can get a service!
Or someone who's tried out the inductive antenna as mentioned on the other thread http://www.xda-developers.com/forum...=0&postdays=0&postorder=asc&highlight=antenna
http://www.expansys.us/product.asp?code=AXF-15S
You can make a perfectly tuned antenna/pickup out of just copper etching on a piece of PCB. Unfortunately, it is infinitely easier to create a distuned antenna from the same components.
After a lot of research it seems the "as seen on TV" signal booster widgets (small PCBs) as suspected dont work.
http://www.bettercalls.com/
http://cellphones-accessories.com/cell-accessories/celphonpow24.html
This is a brilliant site where I found all the info:
http://www.criterioncellular.com/html/reception.html
Whats needed is either:
1) someone making a replacement antenna - as from the internal images shown on this website, it seems fairly easy to remove when dismantling the xda. Why not have a replacement one with an external FME antenna connector. This could then be attached to a small car type antenna.
http://www.tdc.co.uk/antennas/antenna_gsm.htm
apologies if my theories are a little optimistic on this... its just an idea.
2) Purchase of an external signal booster, which can be attached to a small antenna. Then directly plugged into a modified antenna (as 1 above)
3) A seperate re-radiator to boost the outdoor GSM signal inside the home, although this seems expensive! ($279)http://www.criterioncellular.com/html/cellular-amplifier-bda.html
4) as carlos suggested an inductive repeater, you can buy these for GPS systems, why not for GSM signals?http://www.expansys.com/product.asp?code=GPSW-RRAD-45
FVH - Have you noticed any difference with signal using the inductive coupler?

***If this does not belong here I appologize, and feel free to move this if necessary. I just figured the development community is most likely to take this "upgrade" on***
After seeing that someone used Palm's wireless charger on their non-palm phone; I decided to put one on my Droid Incredible.
***This was done to a completely stock Dinc. I did not use any special back, and the stock back gets to stay on (unlike in the other video that I saw)
Wireless Charging the Droid Incredible
**Disclaimer: This will void your warranty, and if you solder something wrong will probably break your phone. With that said I can in no way be held accountable for anything that occurs while performing this “upgrade” to your phone.
>>>>If anyone knows where I can buy that little void sticker that you will see in a picture below, please let me know! If we can get that sticker then our warranty is not voided by doing this.
Supplies:
1.Palm touchstone charger http://www.shopping.hp.com/product/handheld/categories/palm/4/accessories/FB300AA%23AC3
2.Palm touchstone phone back http://www.shopping.hp.com/store/product/product_detail/FB306AA%23AC3?
3.Micro USB cable
4.Soldering Iron (the finer the tip on this the better)
5.Torx T6 screw driver
6.Safe pry tool (or a small flat head screwdriver)
7.Very tiny insulated wires (I just pulled mine out of a USB cable that I cut up)
8.Electrical Tape
9.[Optional] Multimeter to test that you actually made a good connection
How To (Images are of a higher quality (12mp) so I had to stick them in zip files to get them on here):
1.The palm touchstone phone back has a sticker inside of it that encases the wireless charging receiver, so you need to peel this off. Once it is peeled off it will look like this (without the wires soldered onto it):
(Images can be seen in: Palm Receiver.7z)
2.Remove the battery cover and the battery then unscrew the back from your phone (please view a tare down video for details, there are plenty of them on you tube that I used for a reference.)
1.All you need is a torx t6 screwdriver and a safe pry tool, I used a small flat head screwdriver and it worked just fine. Unscrew the 4 screws around the sides and then carefully pry off every place that the battery cover clips on, as they also hold on the red back.
(Images can be seen in: Dinc Inside.7z)
3.Solder on some wires to the USB connector as shown in the below image without soldering onto the pins next to them. This is difficult and takes some time and patience, since these connectors are very small and close (note the polarity in the image, notated in red).
A.Also it is necessary to place a piece of electrical tape over the components right next to the connector (Green box in the image) as they will short out the power and make it impossible to charge your phone if you do not (I found that out the hard way and went back and fixed it).
B.One final note here is that I had to melt down the red phone backing inside to allow the cables to get past the case. See the green rectangle in the image above for where I had to do that. I just used my soldering iron and melted it down, it makes a pretty nice indention for the wires to fit through.
(Images can be seen in: Dinc USB.7z)
4.Now push out the rubber plug in the red phone backing next to the USB cover (this is encircled in Green in the image from step 2).
A.Run the cables that you just solder on through that so that they are sticking through to the battery compartment on your phone.
B.You can also stick on the palm receiver to the inside of your phone cover (note the direction and placement, as this is necessary to close your cover).
3.Note that I placed electrical tape over the wires. This was necessary to keep them from breaking off of the USB connector since the solder points are so small.
(Images can be seen in: Almost Done.7z)
5.Solder on the wires to the palm charger receiver and you are done. Now you just need to carefully place the wires towards the middle of the phone so that you can close the back of your phone entirely (this is another reason why the wires need to be small).
A.Note the polarity of the connection.
B.Also I put a piece of electrical tape over the connections on the palm charger receiver to protect them (not shown in the image).
(Images can be seen in: Wireless Charger.7z)
Here is a video of the end product and how it works:

This could be truly amazing. I can't wait to see more.

Its been done with the Evo, but don't know anyone who did it with the Inc.
http://www.goodandevo.net/2010/06/h...rk-with-palm-touchstone-wireless-charger.html
Sounds really nice. Not gonna try it with mine because I'm too scared
Though shouldn't this be in accessories or general?
What are you doing to align the coils? My biggest concern that's kept me from this is the magnets also would mess up the compass sensors readings which I for one actually value.
Wow, you managed to bring me out of my months of silence in posting...
I feel honored that I can get you out of your months of silence
The coil alignment is handled by the magnets inside of the palm touchstone charger itself (the base unit that plugs into the wall). The metal objects that you can see in the "Palm Receiver.7z" file are actually not magnets, but small circular pieces of metal that get pulled towards the charger base when you get them close to each other. So when you have the phone off of the charger, there are no magnets to mess with anything
Also you will notice that there is a piece of metal behind the coil, and that seems to block the inductive signal all together (because I tried to put it on backwards to no avail). Therefore your phone is mostly protected from the inductive transmission.
The only thing that I noticed, is that the touchscreen on the phone is a little weird when it is on the charger, but I see the same side effects when plugging the phone into a "non-htc" charger (before performing this "upgrade"). **I also saw this on my Moto Droid when connecting it to a 1 amp charger, and I have seen this with multiple other touchscreen devices so I think it just has something to do with the frequency of the charger.
Also in case of any concerns: MY PHONE HAS IN NO WAY BEEN DAMAGED BY THIS "UPGRADE"

Yah, it probably should be, and may get moved (which is perfectly fine by me). I put it in here because I am a developer and much more likely to do this, so I figured the development community would be more interested.

I have a rubber case on my Dinc... would I need to remove it for charging?
___________________________________
Yup.... The ones yoe momma told ya about.... Bad Seed Customs!!
I think you will be ok if it is one of those thin (about 1mm thick) rubber cases. Anything thicker than that and you would probably have to install the wireless receiver on the case itself and remove your battery cover all together.
I tested a thin rubber case that I have (no more than 1mm thick I think) that fits a Droid Eris and it charges as long as its flush to the back of my phone.

Wow, this is amazing, very well done. I think this is the first hard mod I've heard of for an Android. I guess gold cards were a sorta gray area.
I've had my Incredible modded to work with a Touchstone since around June of last year. It works great, but I must caution anyone thinking of doing this to be VERY careful. Experience with soldering and a steady hand is a must. One could fairly easily mess up their phone attempting to do this.
Could you do this with a powermat if you wanted to? I have a few laying around I could use.

What I originally meant was pictures. But now that you've added them and I've seen the glory, this mod is really quite impressive and I'm thrilled you shared it with us. But now that I think about it, could this also do USB wirelessly? That would be pretty amazing.

No, the transmission of data wirelessly is achieved through modulated EM waves. This is simple inductance: a changing electric field creates a magnetic field, a changing magnetic field generates an electric field, so a current carrying loop placed near another loop of wire will induce current in the other loop. The receiver in the phone is engineered to "create" the "proper" amount current to charge your battery when combined with the base. In theory yes, but not with this equipment.
How does the phone treat a USB cable being plugged in - will it charge ok, and have your data transfer rates been adversely effected? I wouldn't think so, since you're only touching the power...

I have used the USB charger and data transfer cables without any problems at all. Also I have copied some files off of my phone to my PC since the "upgrade" and did not notice any extended times or anything that would remotely make me think something was wrong.
I did not run a speed test before and after to see if anything slowed down, but as you said we are only touching the power pins, so I highly doubt anything has changed.
Hi all,
My HD2 running HyperDroid v12 from Pongster is a dream phone. Everything is working excellent except recently I got the digitizer changed from a local shop here in LA and in the process of fixing the digitizer the idiot seems to have ruined my GPS related hardware (which obviously he is not owning up to). I tried all sorts of software remedies (including changing ROMS) but nothing seems to get a GPS lock.
My questions is -
Is there any way to buy and replace the GPS receiver in the phone?
Thanks
The guy might have accidentally removed the connection from the circuit board, I remember seeing threads from before of other's doing the same thing when fixing the digitizer.

They tell you what you need, and instead of the "flat plastic stick", a guitar pick should be fine.
- No need to remove speaker from housing.
- Ignore everything from 1:47, and look at 3:22 from the disassembly video, instead of removing the gps coaxial cable, check if it's actually connected properly, if not, just push it in.

I'll try and find those threads I remember reading, in which the OP and other members had the same problem after replacement of digitizer.

Hi Moon,
I followed the steps in the videos you provided and opened my HD2. The GPS coaxial cable seems to be fit in snug, which I guess is indicative that the GPS antenna itself may have gone bad somehow. Possible?
I did a little searching and found this link where I can buy an antenna from -
http://www.gsm4world.us/oem-htc-hd2-t8585-gps-antenna-board-flex-ribbon-cable-d-03752_579.html
That said, I am not too comfortable trying to replace it by myself. Any chance anybody knows a person/shop in the LA area who may have expertise in such jobs? The one I found in Glendale (CellularDR) is the reason this has happened so I'm not too keen on re-visiting them.
Thanks again for all the help!
Can't you get a separate external GPS receiver and bluetooth it?
It kinda beats the purpose of havnig a all in one device, plus you need to always watch 2 batteries and not just one . But, I must say it is the safe option and worth considering.

New back housing w/antennas
I had to replace the back housing on my phone as it broke (it looked like the plastic had deteriorated), and the new one comes with all 3 antenna attached, and a new battery cover for less than US 20.00. I have better reception now on all 3 radios, and the phone looks new again. If your have to take it apart anyway, why not replace the whole back? I got it from these people, eBay item 350487086071, but there are tons out there, and it was dead simple. Unscrewed the four screws, used the plastic piece to pop the snaps, and that was it.
YMMV, but for only 20, you can rule out the antennas if nothing else.

You could probably buy two new Raiders for $250! Replacement might be the best bet, as you can likely find one on Kijiji for $100 or so. If you have a local cell repair joint, give them a call, and see if they offer the replacement. It might be tricky since the USB on the Raider (as other HTC phones) is actually a special type of HDMI jack that also has USB (known as MHL).
If you're adventurous, you might track down a broken Raider and attempt a part swap yourself. I've not seen the inside of the unit, so I can't say how easy or hard that would be at any skill level...
Hope you get it fixed up!
The part is on eBay you can always try to do it yourself should be a few small solder points

A friend needed this. We ordered one off ebay ( http://www.ebay.com/itm/OEM-USB-Pow...328529?pt=PDA_Accessories&hash=item27c422a1d1 ) and although it required opening the phone up and voiding the warranty, it required no soldering. He doesn't open electronics up very often, and said it wasn't very hard to do.
i was babbling abt this in a thread in the dev forum, thot i'd best do it also here in the proper forum for it:
i changed the USB port in my Raider, was very simple. Six little screws, two different lengths so keep track of them. One screw also holds down the teeny cover under which is where the tiny connector resides that connects the port to the fone circuit board. Once the fone is back together that's where you make the final connection between port and fone.
Slip off the battery cover, undo the six screws, take off that tiny little cover. Carefully work off the entire back housing. There's no front housing, just the screen glass and the fone circuitry bundled together.
Micro-USB port and ribbon connector is fastened to the housing with two more of those little screws. Change out the port with the new one. New part may not be an exact duplicate of the old part: that's ok. Reassemble the fone. Under that hole left by the tiny cover, press home the miniscule plug that connects up the port to the fone.
Put back the tiny cover, fasten back all the screws, and you're done. Port cost me $9 USD plus shipping on ebay.

Hey, dude, I know this thread is a little old, but can you PM me the link to where you bought your USB port? I think I need to replace my port (issues connecting to PC and charging requires wire wiggling), but I've read about certain ports not working with data transfer and only charging, and I don't want to make that kind of mistake.

Hi been having trouble with WiFi being very spotty, and thought it was because of the little Pig Tail antenna used, however after opening up the unit to solder in a proper antenna I found out that the reason it was so spotty is because the solder pad where the original antenna was soldered to was only hanging on because of some glue that had been applied.
I only realised this once the glue and solder had been removed.. exposing the now missing solder pad..
Looks like whoever did the QC spotted the loose solder joint so just put a blob of glue on there lol.
Does anyone know of an alternate location where i can solder in the new antenna? having just has laser surgery on my eyes I really dont want to spend a few hours tracing lines etc.
