Is it possible to add an NFC chip to the Nexus One?

The NFC chip of the Nexus S is located on the battery cover, IIRC. I was wondering if it is possible to install it on our Nexus One.

According to this, it is possible to add the NFC chip to older blackberry phones that didn't come with the NFC. I'm not a very tech savvy person so I was wondering what other kinds of hardware connection you need to make it work?

Well, I would think it wouldn't take much to put a pre-programmed chip anywhere you want. But tying in to the rest of the hardware, and thus software... I can't imagine this is easy.

Yeah I was curious after reading this post as well. If an ancient Blackberry can do it, surely the N1 should have no trouble. Then again, the Blackberry models have always had a sort of built in NFC for interfacing with their holsters, so it might be a build up on that.

I don't think it is NFC. I believe it is some kind of magnetic sensor. The Holster has a magnet and when the phone leaves the magnetic field, it automatically turns the screen on or something. But you could be right that it could be related to NFC.

Most blackberries have dock connectors in their battery doors that allow for power and I am pretty sure data transfer, thus of a new back was inserted, the infrastructure would already exist for it to talk to the phone. N1 doesn't have this on the battery door.

Well ok, maybe not the battery door. But how about the docking pins? They allow for data and power transfer? Sure, it'd interfere with docking if you'd mount a chip on there. But some people might be perfectly happy with that..
Or am I talking about completely different things here?

I'm pretty sure the docking pins would be a viable option, as they do transfer data (tell Nexus One to open clock, open car mode). I don't know anyone who would reverse-engineer that much though

Didn't expect rim to be this forward thinking.

Those docking pins, since they they are not connected to the door are irrelevant. They bear no resemblance to the ones on a bb because you can't just swap out the bottom piece of the phone for one with an nfc chip in it.
The only possible solution for this idea that I can think of (prepare yourselves, it is pretty out there) is to place an "L" shaped tab between the battery connectors on the battery and phone, have connectors on the other end of the "L" that sit on top of the battery, and make a new back cover that has an nfc chip in it, and connectors to the "L" tab. This would only work if there was a way for the phone to send data to the battery, if that were possible the tab would create a fork in the data "road" and allow for interaction between the phone and nfc chip. I highly doubt that the N1 has such a sophisticated battery, but I do know that this is possible because some macbook batteries get firmware updates pushed directly to the battery. So if you were a genius mechanical engineer, the phone and battery could talk, and you had a lot of time on your hands, you could probably do it.

Actually RIM and Bank of America are partnering to do a pilot program of bb's with nfc chips:
http://m.engadget.com/default/artic...wallet-nfc-trial/&category=classic&postPage=1

I wouldn't be too sure about this, but SD cards with NFC chips integrated have been looked at.
Edit - can't put in a link yet, so just google NFC SD card and there a articles on this.
How useful this would be for us remains to be seen. I don't think the NFC drivers are loaded into the passion release...
More than likely, we'll all have changed phones by the time NFC is widespread. I wouldn't get the Nexus S though

is it really possible?

Viewsonic Aims Squarely at the Nook

So viewsonic's 7" tablet just hit Amazon, and is priced at $230.00.
http://www.amazon.com/gp/product/B0...&pf_rd_t=101&pf_rd_p=470938631&pf_rd_i=507846
It's an interesting device that's pre-loaded with a bunch of Amazon apps (including teh Amazon App store). Sorta like a pseudo-Amazon Kindle Color.
And Viewsonic is aiming squarely at the Nook with this device, just scroll down to the end of their product page for a spec-by spec comparison:
http://www.viewsonic.com/products/vb730.htm
Funny thing: though the spec sheet mentions that both tablets have a 7" screen, it conveniently fails to list their resolution. (The Viewsonic is just 800 x 480).
Still, the fact that this thing includes built-in stylus technology makes it a serious competitor to HTC's 7" View tablet. If it weren't for the low resolution screen, i might even consider one myself.

Wow for 230.00 bucks i would of bought that.... that's a great priced little tablet.

Yes, the NOOKcolor does have serious competitor.
Feature-wise, so far that Viewsonic has offered a lot more. Few down-side
+ far less superior screen
+ no wireless-N
+ seperate charger port. NC uses microUSB port as charger
+ thicker 14mm (vs. NC 12mm)
But it gains
+ default bluetooth 2.1
+ microphone
+ webcam
+ 1GHz CPU (can it be overclocked?)
+ regular miniUSB
+ miniHDMI
+ 10hrs vs 8hrs battery life (not much diff. i guess)
+ front speaker (better than on the back like the NC, i personal feeling)
+ lighter 15.2oz (vs. NC 15.8oz)
Next question, can this V730 be flashed and run CM7 like we did the NC?
I think if it has IPS screen tech, it will beat the NOOK.

What I've come to learn about Android phones and tablets is, the specs are near meaningless, the real strength of a device is it's community. Imagine the Nook without CM7 or even root... I have a friend who has the Galaxy Tab(CDMA), which pretty much out specs the Nook in every way, but I would never trade, because the Tabs community is basically just a rag tag group with no star action. Matter of fact my friend is jealous of all my Nook can do...
Most device manufacturers load down their android devices with so much crap or don't optimize enough that even dual core devices run like crap...

Why would it beat the nook? Even if it were an IPS screen (and knowing Viewsonic, it will be the cheapest crap they can find; already demoed by the pathetic 800x480 screen), the other "extra" features really aren't that great.
I will knock bluetooth off your list, since it works just fine in CM7 (yes, range could be better, but frankly, i have never had a problem there either).
So, it leaves you with some extra ports and a crappy webcam. Sorry, but i will take the amazing quality IPS screen any day over some extra ports and webcam. (BTW - the "regular" USB thing is silly, since "regular" microUSB plugs in just fine to our port..)

The 800x480 resolution makes it a non-starter for me.

So you're telling me if the VB730 has 1024x600 IPS screen, just like the NC, it is still a bad one, and can't compete to the NC?

I agree. The biggest selling point of the NC for me is the beautiful IPS hi-res display. Viewsonic won't have a solid competitor (IMO) with such a low-res screen.
Stock-for-stock, it'll be a better option for Joe Schmoe in the market for a cheapie tablet, though. That is, unless a Nook owner gets to them first... haha

IF it had as good a screen as the Nook, then yes it'd be an interesting stock alternative. But as it's spec'ed now with thet 800x480 screen, that probably makes it a negative for a large number of folks. The Bluetooth is a plus vs Stock NC, but not versus CM7 NC. The mini-USB port vs micro is nice in that it's probably a fair bit sturdier than what we've got now, but all in all, not a huge deal.
The mini-HDMI is interesting, but again, when paired with the 800x480 screen, it's unclear whether it will push out worthwhile resolution. The thing that will be interesting is if they come out with a version that's got a higher resolution screen, and what the real detail is about their CPU/GPU.
The stylus is a marketing hype positive against a stock NC. You can obviously buy a stylus for any capacitive screen tablet for under 20 bucks. Whether or not the Viewsonic "RiteTouch" is any good, only time will tell.
The rest of the list is pretty much vs the Stock NC, so this is a stock vs stock argument. We have no way of knowing whether or not the hacking community for this device will be as strong as the one for the NC, so again only time will tell.
But right now, with what knowledge we have... I still feel NC is better, at least for my needs.

That's what I stated up there, the VB730 has far less superior screen compared to the NOOK. Also said if it has the same screen tech/resolution as the NC, then it is a serious competitor. Assuming xda-developer as well as cyanogenmod gurus will tackle this little tablet later on like they did for the NC, then this guys would be good.
Don't know why this site has too many hot-head blindly jumped on defending their Nook.
Can they relax and open their mind? Geez

I think it has to do with the unique nature of unlocking an e-reader for use as a full-fledged tablet, and it's great hardware for the price.
Also, I wonder how much a comparable screen would raise the Viewsonic's price.

Have you folk ever actually tried to use a capacitive stylus? I mean, give me a break . . . unless you like writing with a crayon, they are mostly useless. Pretty much impossible to use one to underline *.pdf files (or, for that matter, comfortably write).
For me, depends on the stylus technology. If you're getting something like the HTC Flyer's stylus, I think it would be a good deal, so long as there is more built-in software support. But they're kind of vague about the whole thing on the website. I haven't been able to find more information about "RiteTouch" technology. I'm waiting to see what somebody serious says about how the stylus actually works with the device.

Same here. Looking for a review. If the stylus works well, I'll probably wait and see if they release an upgraded version with a 1024 x 600 screen and then maybe.

This. When the honeycomb/ICS source code launches, we have a strong enough community that we will be seeing a port, and its going to completely transform our ereaders into full fledged tablets. This viewsonic tablet probably wont have that support if previous models are anything to judge by, and the horrible screen resolution means that even if it did, it would be stuck with the phone UI since there simply isnt enough space to show tablet optimized applications.

So the first Amazon reader review is in:
http://www.amazon.com/ViewBook-VB73...dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1
Reviewer claims it has a RESISTIVE screen! Whoa! Hadn't seen that mentioned anywhere. In fact, I hadn't seen any mention either way. But if this is true then it surely makes a big difference (and explains the included pen). The next question is: is it multi-touch? I have to assume it is, because it would be pretty crippling if it weren't.
Now, I'm not going to immediately discount a device with a resistive screen (no doubt the technology is improving day to day) but I'd definitely want to read some in depth testimonials on how it compares to the capacitive screens we've all grown to know and love.
(EDIT: The Tiger Direct page lists "resistive screen" in the specs: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=782735&CatId=6957 So this Nook competitor is becoming less impressive the more I read about it.)

Depends on if they are using new multitouch resistive controllers.

If it has a pen input, then resistive is really the only way to go there. As said, writing with a capactive stylus is annoying at best.
As for multitouch, usually that is NOT possible on resistive but I don't think it's impossible either.

Really, the advantage of capacitive touchscreens is probably a little overstated. I currently have two resistive touchscreen tablets. The T91MT was one of the first cheap tablet devices on the market, and it has a pretty sensitive screen with multitouch features. Most people would have trouble telling the difference between that and a capacitive screen. My Pocket eDGe has a much less sensitive screen, although its ability to use a stylus makes it much more useful than most recent Android devices. I'm not entirely convinced that a capacitive touchscreen is the best option, especially when you consider that the technology has likely advanced over the last couple years.
So . . . a resistive touchscreen . . .
(1) can have multitouch support;
(2) can be used at any temperature;
(3) can be used with any object that applies pressure;
(4) is extremely accurate;
(5) is cheap.
I'd still like to see how the stylus works. It would be really neat if it had palm rejection.

That amazon review is mine .. I had a gift card to amazon so i ordered this instead of the nook.
Since writing that review initially the amazon market has more annoyed me as I am lacking things I wish i had from the google market and I can't seem to find any drivers to support this device to make any attempt at rooting it so I can get the google market on it.
Hulu+ runs on it though thats a bonus i think.
The screen is difficult to tell if it is truly a resistive screen or something else, as why i put in the review it appears to be a hybrid of some kind. Using my Bamboo Capacitive Stylus I am able to control the screen and all just the same as using the included Rite Touch stylus, which as far as i can tell is nothing but a regular old resistive plastic tip stylus. On the Multi-touch issue I've read it is but it doesn't appear to be as I can't pinch to zoom and the usual multi-touch gestures although the double tap to zoom I use more even on cap screens than the pinch.

I still have problems with bluetooth keyboards, runing nightly 126 and 131. I have a Xoom bluetooth with a modified qwerty.kl file to enable most of the android special keys to work. The three annoying issues with Xoom keyboard is that it will stop working while typing long messages, have to hit power button on it to restart; a key will stick kkkkkkkkkk; and not easy to get out of pop-up for accent keys. You do not see these problems? The best feature is that I can leave power adapter plugged in with bluetooth.
When I use my Logitech wireless usb combo keyboard and mouse I only seem to get the pop-up accent box. The negative is even with a y cable it does not seem to charge nook while in host and v-bus mode. The combination arrow and keyboard interface is really slick.
Anybody else notice these flaws with bluetooth and usb keyboards?

Successfully upgraded the hard drive in an 80G9 250gb

I came to hate this thing, that damn drive took forever to spin up and caused significant lag on the tablet constantly, I regretted not just getting a flash based one. So, this week I got bored and pried it apart. Pulled out the drive, used Gparted to shrink the partition to 120gb, copied that partition to an OCZ Petrol 128gb SSD, took it out of the metal case, and sticky taped that bad boy in. Tablet is amazingly fast now Movies load instantly. I never see that hated drive access indicator anymore. I shall see if the battery life is any better. Putting a mechanical drive in something like this was a terrible idea. I have some pics of the guts of this thing if anyone is interested.

yes upload photos, pictures of the tabled opened too. is hd sata? thank you

It is indeed SATA. Has an extremely easy to pull out of the motherboard cable that caused it to short the old SSD I was going to use. So watch that. Also, the original drive was covered in gold metal tape that was a beast to pull off, I suppose for RF shielding. I forgot to take pictures before I took the drive out. The only negative so far is that I now have that weird screen anomaly, which has GOT to be something pushing against the screen's back, I may have gotten a wire in the way. I will yank it back apart later this week to address that. Didn't have it before. It has TWO big batteries in it as well. In the pictures, the circuit board near the top kind of by itself is the naked SSD in the former drive bay. Motherboard is at the bottom, in one of them, you can see the bigger battery laying outside on my table.

Mega props to you. That's am awesome project. I installed a sad in my notebook and it was the best thing I ever did for performance.

Was just wondering if the RAM is soldered onto the board or it is upgradable as I got the 80 G9 8GB non turbo and could do with a ram boost.
Not sure if the innards are the same as the 250GB model but worth asking as you have had it open.

I think that's just a universal issue with the archos g9 tablets.
You just got to re-position your router closer or use 3G dongle.

well, I bought stronger router because of signal, but no change. So I compare my and my colleague Archos G9 80 and samsung mobile and my tablet was about 30-50% worse...
Factory reset I tried

No idea id the non-hdd has it, I only own the Hdd model. Since my case is actually thicker, I imagine it doesn't exist in the non-hdd, and seeing as I. have no micro sd slot. There are physical differences in the models. I was looking at the mobo, as I wanted to upgrade the ram as well, didn't see anything that looked like a SODIMM slot. I imagine its soldered in. I will check again when I crack it to fix the screen issue. I will attempt aome sort of legible walkthrough when I get some time.

It's so much faster in this too. Battery life seems much better so far. Off charger all day, light use, at 75% now. I'm wondering if the HDD model has the 2 batteries to compensate for the extra drain. I found it odd that it has 2 different sized batteries wedged in it.

Physical shape/size doesn't matter, I bet they have the same capacity (connecting batteries with different capacity together would kill them both soon)

way cool reverendbill! (and assuming rather broadly that you are clergy, good luck with holy week!) i am considering purchasing the new 1gb version of the g9 101 250gb and am inspired by your work. i am pretty clever with a screwdriver and an idiot with programming and would really like to know how you get all your data off the old hdd and onto the new ssd. please be as detailed as possible (i'm sure others would love to know as well) pm and email if necessary. thanks in advance for your time and patience!

did you have to do anything special to the new drive? I see you did a partition copy, but is that needed if you don't care about loosing whats on it? Right now, I only have two movies and a few songs on mine because I just got it and haven't done much as far as copying my media to it. Yet...
So I'm just curious if getting a new drive to work is as simple as formatting it correctly and that's it. Guess I'd have to format it under linux so I could do ext4 properly? Or will the archos format it just fine?

I tested battery drop after in 3 different gen 9 archos...one with original, one with a massive 1TB, one with M4 SSD...
No significant battery improvements...Giving it's not scientific test but still.
Every time I measured battery after one how of playing video and always had a drop of around 25% to 27% in both of them..
I also tried a hybride SSD/HDD seagate and same thing.
So please do the SSD replacement for other reasons; quite operation, less, heat, less weight, less failure. As af as speed and power consumption not very much to gain acording to my tests.
The only explanation may well be that since Archos is already pairing Flash to HDD and caching...the HDD is turned off as needed. Ran seveal speed test reading and writing...and did not see much change...I guess it'all just go thru the cache flash used by the HDD versions of Archos.
That was my experience. I reverted back to my 1Tb HDD..No gain for me with an expensive HDD. The hDD is very cheap and if it fails I can still replace it just like that.

Sure... see above. You'll never find something like a SODIMM slot or similar inside cost sensitive devices like tablets. Please be aware that most of them are not x86 but based on ARM SoC's.
The architecture is basically very different to what you've learned from your PC at home (there's also nothing like a PC-BIOS).

Would you be able to post pictures of how to open it step by step?

I have G9 80 16GB Turbo. The plastic part of the inner micro USB feeder is broken and sticked out to the USB charger pin. My USB charger cable now blocked by that and cannot be use anymore. Now in the feeder just remain 4 tiny metals without plastic support (4 USB pins connector) and not able to take charge by anyway, bricked because of no battery power. It was just 2 months old and no warranty since I bought it in airport transit.
1. I've checked my Archos and did not find any screw other than single screw in the USB 3G compartment. I really thankful if you can write step-by step dismantle procedure.
2. Can you share the shape of USB type soldered to the PCB to enable me order the part and soldering it alone.
3. Thankyou in advance.

Oneplus Hardware Back Mod + Larger battery

Hello there, I am pretty new to this forum so please advise me if there is anything wrong with this thread.
I own a oneplus 3 pretty much since the release date, and I have been very happy with it, except for the not optimal battery life.
Now, as you can take from the heading of this thread, I am thinking about rebleacing the back of my oneplus 3 with a larger one, idealy one that covers up the battery bump, so I can fit in a larger battery. Additionaly I probably will need to transfer the antennas, and do something about the speaker and microphone ports.
I would like to make the back out of aluminum via a cnc service online, but for prototyping a 3D printed solution would probably be sufficient. The other question is, where to find a battery that is larger than that in the oneplus 3s standart battery, but still beeing able to fit it inside the space made availible by the new hull.
I would love to hear your thoughts on this project, especially considering problems, that could occure.
I hope this project is interessting for some of you, and we can make the op3 even more awesome.

Maybe you could get a 3t battery and replace it. It's bigger in capacity,but same in size. Like Jerry did here

That wouldn't work since the battery is different voltage when charged fully. You're gonna have to find a 4.35V (max voltage, I think the nominal voltage is 3.8V) li-ion battery that is the same size in thickness and height but has deeper depth.
Anyways this project sounds like it could have some potential... I'd be really down to see a CNC machines aluminum back cover that can accomodate a larger battery. I would buy one in a heartbeat

Some guys did the swap in the lg nexus 5-they placed inside a lg g2s battery which is 3000mah vs 2300mah! It worked for them,so i think there is a chance for this swap also. Maybe we can also mess around with the kernel to make it work. All of this sounds easier than making new back cover

That's because the Nexus 5 and LG G2 batteries were the same voltage. This has already been tried and at first it didn't charge fully, then OnePlus implemented a safety feature that detects when a OP3T battery is installed and doesn't allow the phone to boot. We could make a kernel that charges to a higher voltage (the opposite of bedalus' BLX mod in his moxie kernel) but it could be dangerous and isn't worth the risk.

Little off topic but any good quality replacement batteries out there I can replace with?
I do love this idea but there's no way to avoid opening your phone, so be very hard to get everyone wanting one.

Well it's super easy to open this phone so it's not that big of a deal.
And check out witrigs.com, they seem to have good quality parts and have a replacement battery for this phone. I took the plunge and bought a new screen since I cracked mine real bad but it hasnt arrived yet, I'll be posting a review on it when it comes.

Actually I do not think, that the voltage would be such a large issue, as the voltage of a lion battery is changing constantly with its charge level, there probably is a voltage regulator of some sort in place anyway. I think that software would be the bigger problem, as phone manufacturers probably don't want you to make there phones better instead of buying their new ones

i personally changed nexus 5 battery with Lg G2 battery, no issue in charging or voltage difference and backup is excellent although When i check with AIDA 64 Battery info showing 2300mah but i know backup is improved and as like 3000mah battery,
and also changed OP3 battery with OP3T No issue at all

Can you link me to which battery you bought?
and the ROM you are using?
Any software mods done to make it support the battery?

How come some users reported it as not working but works for you. Maybe old firmware?

External NFC readers...

Bit of a shame they scrimped on the NFC reader / writer. I found it really handy on my Nexus 5 for topping up my travel card and have missed it on my current phone.
I've seen external micro-usb RFID reader / writer doodads like this one - which obviously wouldn't work since it would need to be usb-c. Has anyone ever used one? Any idea if these types of solution (if usb-c) could allow an F1 to write to an NFC tag? Obviously it's not something you'd want to leave plugged in, but if it worked it would be handy to pop on and off when required

If you really need the NFC , you should think about any good smartwatch with NFC. If it is acceptable for you to use any smartwatch , it will be the best use of NFC interface we can imagine.

Thanks for the reply, but that doesn't really fit my use-case plus smart watches ain't really my thing. Gonna recommission my Nexus 5 with the sole function of adding credit to my smart cards

I came across gadget by some reviewer which was a ring with an nfc chip embedded. Smart watches are costly and in this case might even be as much as the phone itself. :S

Get different phone. Really.

Yeah, I bought one a year or so back. Didn't work! My Nexus 5 couldn't find any trace of an NFC tag

If this was a deal breaker I would but as it goes, NFC is a "nice to have", while the F1 has all the higher priorities covered

I have a same problem. I love Poco F1 but this feature is pretty bad for me
I thinking same way.. but I can't find any small usb-c reader

The obvious option is to buy a micro-usb NFC reader/writer like the one I think I liked to above and a micro-usb to usb-c adapter, but I've no idea if the devices actually work. Rather than order one and wait weeks for it to arrive I wondered if the wisdom of crowds might help...

This is a 300 phone that should be as fast as a OnePlus 6 and an S9+. Of course they need to cut corners. Plastic back (unless to get the Armor), no wireless charging, no NFC. I'm OK with all of that in a ~300 dollar smart phone. It has a Qcom 845, water cooling, 6GB of RAM, and decent camera. It is so cheap I decided to order one to play with it. I've never been a big fan of MIUI but I'm hoping the develpment community will provide lots of options. My bet is this phone will have a lot of development given the specs and price.

@Mike02z We are ad idem

Generally,get xiaomi 8.
Secondary,wait for mi band 3 nfc edition?

I still don't get the liquid cooling part. The teardown showed no liquid inside..

Yeah, I think that might have been a fib. As far as I've understood it, it's a rod thermally conductive metal, so it draws hear from the soc to other areas of the phone less likely to overheat (though when I was watching the teardown it looked like it was drawing hear to the battery - hot batteries didn't do Samsung a whole lot of favours. Jus' sayin')

Okay so I saw a galaxy s9 teardown who was inspecting the liquid cooling in it and found that the liquid is basically inside the metal heatsink. The liquid can physically move inside thereby facilitating heattransfer. Guessing Xiaomi used that.

You can always use another launcher if you don't like MIUI....
That should fix that .
What I love with Android, if it's broke you can fix it how you like it - mostly...

Back to the subject of NFC devices, it seems the one I initially linked to in the first post is only an NFC tag reader, that is, it will read an NFC code from a tag. Writing is a different matter and probably requires something more like this.
Scouring t'internet revealed some other interesting idea though. Apparently there have been trials of NFC reader / writers built into microsd cards (even SIM cards) though it's not clear if any of these reached the market. That would be a much more elegant solution than a plug in external device.
Does anyone know any more on this?

Does NFC feature came with galaxy gear s3/watch a writer or reader only? Can it be use to top up something like eMoney card?

I'd assume they would read and write, but idk.
Not sure about emoney cards, but my Nexus 4 and my Nexus 5 can both top up my Leap Card (an Irish travel card for trains, trams, buses etc)

This will not work. The NFC hardware should have secure element. There are microsd card with NFC.
But I have not seen Google pay supporting it.
