Data Acquisition and Signal Processing using XDA Exec - JASJAR, XDA Exec, MDA Pro Accessories

Dear All,
I am currently developing a Nondestructive Testing system using a novel pulsing scheme which operates in a relatively low power application. In order to capitalise on the fact it operates in low power i am trying to develop a system around an XDA Exec. I have a DAQ card from C-cubed, DATAQ-CF2 but unfortunately the sampling rate is limited to 40kHz.
I would be able to design a separate Analogue and Digital circuit for signal processing to extend the sampling rate to 5 Mhz but i am unsure if it would be possible to interface this to the Xda Exec via USB (or any other type of interface)? I have attached the file which shows the multilayered PCB design and the BNC connectors, connects the circuit directly to the transducers. You can ignore the Comm. circuit as the XDA Exec would do the data transfer. All i need is to implement the Digital and analogue circuit to the XDA Exec. I have Pocket PC software for Analysing the signal (PocketDAQ Pro 2.3, Virtins Pocket Instrument 1.0).
Could anyone please advice me....maybe someone from HTC? I know this is a little off topic but just comes to show the versatility of the XDA Exec which i would like to exploit.
Thanking you in advance for your time,
with my best regards,
Ravi

Exec - HTC Universal External Antenna

:?: I need a cable to connect to the phone antenna ports on the device - the port is smaller than the ones to be found on some mobiles (such as my old trusty Nokia 6310i) and I need to find out what type of connector is needed.
Does anyone know where a cable can be obtained or what type of connector is needed ?
I need a connector also
It took me weeks to find the special connector for my XDAII. Now I'm in the same boat for the Universal (JASJAR). I've been searching the net for a while to no avail, but hopefully I find one soon and let us know. :?
Sorry just too lazy to go through the manual so decided to ask the enlightened friends on this forum. I want to know if the antenna socket provided at the back of the Universal is for GSM signals. The GSM signal in my home room is too weak so I thought that attaching an external antenna would be beneficial to the strength of the GSM signal. But obviously even if it is so attaching an antenna would be possible only once we have found a suitable connector.
Kind Regards
I mounted an antenna outside my house
For the last 2 years (with my XDAII) I've used an antenna I ran through my outside brickwall and mounted outside my house. It helped the phone go from NO reception to a pretty good signal. I still have the cable running to my office/desk and all I need now is the connector. It has to be out there somewhere. I ended up buying my previous connector from http://digikey.com, but it ended up costing $30 ... but it was worth it. I'll do more digging today and see if I can find out more.
Oh and by the way, I was using GSM on my XDAII and the manual for the Universal says the connector (closest to the center or USB) is for GSM/GPRS.
Anyone find out what adapter fits the jasjar? My adapter for the pda2k does not fit.
I'm still looking
I've sent emails to PDAGold, HTC in Taiwan and i-Mate to not avail. I'm going to keep on looking. Obviously someone has to know.
Some progress - I've found out the connector type
The connector on the phone is a Amphenol MHC-H196.
I've posted a pdf with all the specifications of the connector on the circuit board ... http://wiki.xda-developers.com/uploads/MHCH196.pdf
Now it's just a matter of finding the correct adapter.
Well I gave up trying to find one and made my own
After spending many hours looking and getting an official "not available" from digikey.com (who I got my XDAII adapter from) and imate techsupport ... I decided to make my own. I haven't been able to test it with my Jasjar yet, though, since it's still being repaired at Topp Solutions in Miami.
I ended up using 26 gage solid wire (which is .4mm diameter) and a .062 inch (1.6mm) diameter female pin connector. This is smaller than the diameter of the connector on the phone, which is actually 1.82mm. Although, I expect it to expand slightly (permanently) when it's slid over the connector on the phone. Obviously, it's very crude for now. I just want to see if it works then I might make a prettier one. I included some pictures for fun. By the way this cost me about $9 in material (which I can use for other projects) vs. $35 for the last adapter I bought for my XDAII through Digikey.

Did you see the interesting comments made by WilsonsElectronics. HTC really stuffed up with this one.
Is there any news on this matter.
At the moment I have sent an information pack to www.pasternack.com and I am currently waiting for a response. These people do customised products. See under technical support. I will keep you friends informed.
http://www.pasternack.com/ContactUs/ContactInformation.asp
I am after an adapter to get a signal booster... www.digitalantenna.com
I talked to them about three products. there email follows
Description Part Number List Price
60dB gain repeater system 4KSBR-50U $699.95
40dB gain repeater system 4KMR-30U $559.95
Direct Connect Amplifier DA4000 $299.95
DA4000:
The DA4000 amplifier must be purchased with an antenna and cell adapter cable and is a direct-connect system. The antenna is placed on the roof and connects to the inside amplifier which with the correct adapter would then connect to the cellular device. We have many adapters for different phones and air cards. If we do not have the adapter for your type of phone or air card the other option is a wireless repeater. However the direct-connect amplifier can provide higher performance because you are directly connected to it. Please use the link at the bottom of this email to download our 2006 on-line catalog. On page 28/29 is our Cell Adapter Cables which lists the adapters per make/model of cellular phone or PC card.
Description Part Number List Price
Direct Connect Amp. DA4000 $299.95
9dB cell antenna 288-PW $129.95
Cable 340-50NM $79.95
Adapter Cable pg 28/29 $19.95
4KSBR-50U:
The 4KSBR-50U system comes with an external antenna, 50' cable, amplifier/repeater, power supply and an internal antenna. So the external antenna can be installed on the roof with the cable going to the amplifier/repeater inside the house. The internal antenna is also plugged into the amplifier/repeater and is installed inside the house. There must be 40' separation and a wall/roof/bulkhead structure between inside and outside antennas.
With a good cellular signal outside the house the 4KSBR-50U system can reach as far as 40 feet from the internal antenna. Generally the SBR can penetrate 1 or 2 inside walls only and each wall will reduce the 40 feet coverage. Also keep in mind the weaker the outside signal the closer you will need to be to the inside antenna. The 4KSBR-50U system must have a signal that is at or greater than -90db to be able to amplify/repeat it.
4KMR-30U:
The 4KMR-30U, 40dB gain dual band cellular repeater system, comes with an external antenna, 30' cable, amplifier/repeater, power supply and an internal antenna. So the external antenna can be installed on the roof with the cable going to the amplifier/repeater inside the house. The internal antenna is also plugged into the amplifier/repeater and is installed inside the house. There must be 20' separation and a wall/roof/bulkhead structure between inside and outside antennas.
With a good cellular signal outside the house the 4KMR-30U system can reach as far as approximately 18 feet from the internal antenna but will not penetrate walls. Also keep in mind the weaker the outside signal the closer you will need to be to the inside antenna. The 4KMR-30U system must have a signal that is at or greater than -90db to be able to amplify/repeat it.
Try here for antennae and adaptors
I haven't checked this very far yet but the picture seems to match...

More detail...at : http://www.boatersphone.com/Adapters.asp
Its the Nokia 359914 Multi Manufacture Cell Phone adpater, You stick a velco thing on your phone next to the internal adapter, and slide the nokia adapter into it. This is NOT a direct plug in into the External GSM jack of the HTC Universal device ( ie Jas Jar ). But looks like our only safe option. Not sure how the velcro thing goes on the device, the Jas Jar has a plastic back ( over the battery )???
Works on these networks, the site says : 900MHz/1800MHz/1900MHz/2100MHz networks
..."This is an extremely effective new kind of adapter, it works on a similar rinciple to the clip-on adapter, with the exception that it is tuned to work on more frequencies. We have tested it on all UK frequencies including 3G, and we know it works on the American 1900MHz band as well! This adapter was originally designed to work on Nokias but we have successfully used it on other makes of phones, making this a (hopefully!) truly universal adapter. It will work on 'candy-bar' style phones which have an internal antenna.
This adapter is two-piece, one piece is a velcro pad which has sticky-back plastic on it, and sticks onto the back of the phone over the internal antenna. The second piece is the adapter itself, which has velcro over the inductive plate, so it can be easily removed, and has a lead so it can be connected to an external antenna. '...
Where did you get the Information that it's a velcro adaptor?
reading the Page it says:
Plug-In Adaptor for O2 XDA Exec
More details about plug-in adaptor in general:
This kind adapter is called a plug-in adapter, for the simple reason that what it does is plug straight into the port on the back of the phone, and provides a cable connection to the antenna.
The plug-in adapter is preferred to the clip-on adpter, as it works on any mobile network.

I wrote them an email i'll keep you informed.
If you can get a plug in one then fine, but further down the page is where I get my info from. I highlighted in bold, just in case you cant see good.(Ha).
I'll bet the Jas Jar gets allocated the valcro one. As my experience is that its very difficult to find a plug one for the Jas Jar /O2 Exec.
Although I learly can read your bold text and being able to find this on on the page i really have no clue where you find the connection between the velco apdator and the O2 XDA Exec since it's marked with plug-in adaptor. Well we will see.
My apologies, yes "Plug-in Adapters", for "XDA, XDA II, XDA IIs, XDA Exec "..
BUT be carefull, the GSM external jack is very weak as per Wilson Electronic comments. Post me any confirmations of the plug in adapter working.
'Universal' adapters that apparently plug in
Their News page has a paragraph that describes a new adapter for various flavours of the Universal (although calling it Wizard to add to the confusion!) and warns against plugging in incompatible adapters. The adapters page lists the HTC devices under 'Plug-In' not 'Clip-on'. So that's why I posted.
I sent an Email after posting here, but it sounds like they are a small outfit so be patient!
Be careful with making adapters for transmitting antennae. For receiving antennae you can get away with almost anything, but for a transmitter a bad match on a connector will create reflections and emissions; it might even damage the transmitter (don't know if that's a problem here). If you don't see a clear increase on the reception bars with a well placed antenna, the adapter may be sending all the power straight back, doubling the voltage at the transmitter. Make sure everything is matched to 50R.

Reply from 'Boatersphone'
Can you do an adaptor from the obscure Amphenol MHCH196 socket on the HTC Universal Windows PDA phone? (XDA Exec, MDA Pro etc.). Presumably the other end is an FME f connector for the 'standard' phone antennas. Or alternatively the other end is a portable (non-mounted) antenna on 1800/2100MHz.
Many thanks
+++
Hello,
Yes we have an adapter to connect the HTC Universal to one of our antennae and you are correct about the FME F connection. We don't supply an adapter direct to an antennae, only in a two-part system via an FME connection, to allow for changing of either part.
If you require a portable antenna we have a 3G/Multiband antenna with a magnetic base (on 850/900/1800/1900/2100MHz frequencies) or we have a T-bar window antenna, which is 3G/Triband, although this doesn't produce as good results as the magnetic antenna.

O2 XDA -----> XDA2 Connector Difference???

Hi all, hoping somebody can tell me if here is a difference in the connectors at the bottom of these 2 phones??? The reason I ask is because I have come into possession of a Professional GPS Carkit for a XDA2 whic I have modified cosmeticly to accomodate the XDA. All parts other than sound and microphone are working. I would appreciate any guidance some of those in the know would be forthcoming with.........I have put my phone back to standard with the rom etc to be sure the upgrading of it had no adverse affect, so it is exactly as I bought it now, and still doesn't work properly
Check the wiki for the connector pinouts to confirm they are the same. They only device using a slightly different 22 pin connector is the blueangel with two ridges in the sleeve.

my xda1 got stolen and i could use both the cradle (xda1 cradle is soooo much better then xda2's)
and charger connector (of cause)
and headset
ok......a little progress nowhere really but, anyone got ideas on this........I pulled the control panel apart on the car kit, i have found that if i put the phone in the cradle whilst on a call and the sound comes through the speaker when it beeps to say it is in the cradle???? Upon checking it further, the control panel clicks, i presume that it 'opens' the connection to the speaker, but will close the connection and not reopen it if i make a call from the cradle tus rendering the speaker an the mic inoperative. I have found that the 'car on' wire appears to go through a resistor once on the board so could this be cutting down the input too much for the signal from an xad1??? Anyone with some technical knowledge on this would be really helpful. Thanks in advance

[INFO] i'm Watch hardware

I did some research on the internal hardware of the i'm Watch Android watch and found out a few things:
The CPU is probably a MCIMX233CJM4B or maybe a MCIMX233DJM4B (the latter is only spec'd for temperatures down to -10 C, which wouldn't be suitable for a watch) and come in BGA169 packages.
Since the CPU only has 32 KB SRAM, external RAM is needed (supported types are mDDR and DDR1) and can most likely be seen next to the 4 GB flash and the CPU itself in the presentation video on their site (3:42).
The CPU has many things built-in such as a resistive touch screen controller, 1.5W speaker amplifier. It also has a host of interfaces; SAIF (Serial Audio Interface) which according to the data sheet could provide hardware accelerated Bluetooth audio, I2C, 2x SSPs, 2x UARTs, JTAG and USB with host mode.
The circuits are split into 2 separate boards, maybe with the Bluetooth chip on the board opposite to the one with the CPU on it.
The SSPs are basically highly configurable serial interfaces and also natively support the SDIO interface, which in turn might enable us to hack in some cheap SDIO WiFi card (found out there's a TI 1271 chip which someone used with Android and a Beagle Board link). Reaching this connector might not be possible from either the hardware nor the software side, but I'm an optimist .
Data sheet for the CPU is available here, I'd recommend page 33 and 1411 to get your inspiration going.
TL;DR
CPU is narrowed down to 2 options
WiFi might be possible with extensive hacking

huh, how to do what?
I picked one up
is there a major forum discussion somewhere for this watch?
I have one (since 3 days) and i think it is too soon for this kind of products.
The software is slow, battery should be longer than at least 5 days and bluetooth it is a technology than i never like it at all. By the way, if you try to use the i'm watch as a speaker, the quality is very poor for your calls.
on the other hand, this tecnology it is beginning and i believe future will be based on this kind of products.

Help!!!! Create - Developer's Choice: Device Connection Protocol

PROPOSE: The creation of a connection protocol that will force/enable standardization of all mobile devices... One in which that can work with current technology connection no matter the device. Simple embedding the wires into a custom case that will act as the ALL-IN-ONE adapter.
LIKE the 19-connector apple protocol or the PDMI (Portable Digital Media Interface)
While, this case will add to the bulk to older/newer devices I would rather gain the ability to use multitudes of accessories without the need of multiple adapter connection.
ADDITIONALLY: I truly believe we should think about apples supporters and help them as well by developing this connector with them in mind... This will force the market to stop deciding to design apple, android or windows and focus on making cool accessories and letting the customers figure it out.
I hope this made sense... I did call three case companies and two wire companies and they stated they liked the Idea but do not think there is a large enough audience to ensure success...
THIS IS AS FAR AS I CAN GO... I CAN COME UP WITH THE MONEY TO START THE PROCESS BUT LACK THE KNOW-HOW AND SUPPORTERS TO MAKE THIS A SUCCESS....
The Standardized Developers Connector needs to not required the need for hardware or drivers. Developing for the future while enabling the past to connect to the same accessories....
HOPE This made sense any questions or comments let me know...
Image a case with the standardized connection but you can add additional specific to your need to alleviate the need for another adapter... EXAMPLE.... The standardize connector on the bottom a head phone jack at the top and hdmi and multiple standard usb to enable a pc experience at any hdmi capable screen and mouse and key board.
Then when I am home I can plug my standardized connection into my media setup and use my bluetooth keyboard mouse and game pad and utilize my big screen as a media center...
Then go the my favorite bar to open spin night plug my standardized connection into their Standardized developed spin tables and battle the other contestants...
Then when I want to upgrade I plug my standardized connected device into a cluster of old devices that I will pass forward to kids of friends and families but until then they will create a virtual power house of processing for my new interactive input device...

Diy nfc antenna extender??

Is there any way to extend the distance my phone can communicate with nfc devices? Right now I need to be within an inch or less it seems but I'd like to extend that to around 5 inches if possible?
Sent from my SAMSUNG-SGH-I747 using xda premium
Interesting article
In theory, yes, it could be done. The challenges are that NFC uses a relatively low frequency (13.56 MHz), which requires a longer antenna (22 meters). The second is that NFC tags are powered by the reader, so the signal at the tag has to be powerful enough to activate the electronics.
I wonder if you put the tag at the focus of a parabolic antenna if you could increase the range? I'm guessing not by much, since the power transfer is over the magnetic field (like a transformer).
wouldnt this also increase the security issues? at one inch its really hard to get the phone to detect anything unless YOU want it to..at 5 inches, a person standing next to you could do it.
I think one would have to have more turns of coil and more power, but what I don't know is if the coils are "tuned" to a certain frequency
Sent from my SGH-T989 using xda app-developers app
The coils are almost certainly tuned to the 13.56MHz radio frequency. The issue is that the power is transmitted by a magnetic field. More coils helps that at the expense of the tuning.
Check this NFC Extenders that would help
Check this NFC Extenders that would help
It has two NFC patch kit, one is for NFC smart phones, the other one is for NFC tags.
It could extend the NFC reading. Contact info @getsmartcard.net
