homemade antenna (untested)

Homemade NFC antenna.. Will test later & fixture w/ electrical tape.. May need to b modified but hopefully has similar strength to original antenna.

I may also attempt to jump clipped circuits in original antenna. So much fun TBD, but gotta run errands w/ wifey now.

Will update..

Edit: wireless charging isn't working. not sure what's going on..

Edit 2: wireless solder joints broke off.. Not sure when this happened, but it prob affected all testing to date.. I will fix this Mon at work (over lunch) since we have a nice 5x scope + small soldering tips. I've already prep'd the Ethernet wire so its ready to go (like flysmod setup).
[ONE General] inaudible101:
Please let us know how the NFC antenna is working out. I'm pretty skeptical to be honest, but if that works I will be doing to for sure.
[ONE General] FloopyDoopy:
I'm definitely going to try this if I manage to get one
[ONE General] :
Minor Update

Will update when I have more info.. Wireless charging is now working, but I didnt get to deal w/ the NFC yet (even tho it was only another 5-10 mins of work. I think anyone who tries the homemade approach will need something like this: http://lairdtech.thomasnet.com/view...elastomers/q-zorb-rfsw-surface-wave-absorbers . I'm lucky & have a sample kit of all different materials like this, but anyone might b able to request samples. It might be required to direct the antenna. I will try electrical tape first to see if it works, but if not, i will need 3rd party materials. Again, i'll update when i get further. (Hopefully over lunch tomorrow.)
[ONE General] :
It just may work.. http://www.antenna-theory.com/definitions/nfc-antenna.php
[ONE General] DrunkFuX666:
So based on what was previously mentioned, I did some more testing with the wireless receiver I got. I had barely been charging the Oppo, so I connected it to my nexus 5 just to see what I could get out of it, and surprisingly, the same coil, although a little unsteady... Managed to charge at up to 670mA, which is very surprising. On the Oppo it would barely touch 500mA.

So maybe there actually is some strange limiter on the Oppo as previously mentioned?

EDIT: So I'm thinking maybe the reason im getting more a charge here is because the wireless receiver was put Directly on the qi charger, unlike with the Oppo where the receiver is covered by a tpu case which rests on the Qi charger... Maybe, maybe...

[ONE General] AJ RIMMER!:
I set mine up last night. I have been looking at the mod for about 6 weeks, and I finally took the plunge.

I have a TPU hard shell case for my phone, and I put the coil under that, on the outside of the phone. I was worried about screwing up the NFC antenna, so I steered clear of it.

What I did was to solder two tiny-gauged pieces of wire on the USB port pins, and then I drilled a 1.5mm hole through the back cover of the OPO. From there, I simply soldered the coil to the wires, clipped on the cover, and voila! Chargification!
[ONE General] Diablo2424:
Thank you everyone for all of the information in this thread! I definitely plan on adding Wireless Charging to my OPO, however, I too want to keep the NFC in working order as I feel it will be used in the future for mobile payments and other features.

I am subscribing to this thread for updates from everyone who is working on solutions to keeping the NFC and getting the wireless charging sorted out (MaH input issue - I don't want a sub 500ma trickle charge :()

Thanks again, and I can't wait to see your guys' finish results so I can add this to my phone!
[ONE General] drnizeguy:
So, for everybody who wants to cut there NC antenna:

I removed mine and removed the adhesive. now you can clearly see where the antenna ends, so you know where to cut!

I ordered a Nexus 5 battery cover to see if I can connect that to the OPO. This because this has the NFC and QI combined,
[ONE General] lapocompris:
How much did you pay for it?
[ONE General] drnizeguy:
€5,- It's an used one but the antenna should be working.

The Nexus 5 NFC and Qi antennas are integrated without masking each other. Maybe we could place the Qi pad in order to achieve this alignment
[ONE General] AJ RIMMER!:
That is a really great idea.
[ONE General] :
I had no luck w/ my makeshift Qi.

I found a NFC tag on ebay that i ordered for $12. I really don't that much about NFC but if only $12 to fix it, that's not bad at all.
[ONE General] lapocompris:
NFC tag or NFC antenna ? You could buy the Nexus 5 antenna for $6 from www.parts4repair.com
[ONE General] :
NFC antenna. (Sorry said wrong thing.)
[ONE General] lapocompris:
Maybe these NFC antennas would fit above your line:

Samsung Galaxy antenna

Xperia Z1 antenna
[ONE General] DrunkFuX666:
Hey guys... I came across this while looking for another 1000mA wireless receiver.

It says it has both a NFC and Wireless Coil in it. Maybe it can help whoever has accidentally destroyed the NFC antenna.

Will it damage my battery if I take the phome from the charger too often? For example, my phone is charging and I receive a call, so I have to pick it up. The I put the phone back on the charger. 10 minutes later I receive another call and have to pick it up again, returning it on the charging pad. Will this type of charging damage my battery?
[ONE General] lapocompris:
You can do this for 1000 times then your battery will die.

Just kidding, the battery life is in full cycles, a 10 mn charge accounts only for a fraction of a cycle.
[ONE General] 4nth0ny:
So do you think I could remove the OPO NFC antenna and replace it with this NFC wireless charging coil from the N?

It is only a few bucks for the part, I might be the sacrificial lamb if I don't see anyone else here take the plunge.

http://www.parts4repair.com/nfc-wireless-charging-coil-for-lg-nexus-4-e960/
[ONE General] inaudible101:
The NFC should work if you light the pads up correctly, but I'm of the opinion that you would still need the circuitry from one of the USB adapters for it to charge correctly. If you ordered one a desoldered the coil and soldered this one to it I don't see why it wouldn't work though. I was considering it after looking at the ones available for the LG G3.
[ONE General] 4nth0ny:
That sounds like a great idea, I do not understand why there is not an NFC wireless charging adapter for sale, there is clearly a need...
[ONE General] DrunkFuX666:
I'm thinking maybe because it will be too complicated to implicate or add a universal NFC reader ability to all phones via the Micro USB port. The wireless charging is just a coil generating charge to go via the route of the normal USB charge cable. NFC will be a whole different thing.

Another thing I would like to mention regarding you planning on getting the Nexus4 charger coil, I would advise you not to. Because if you remember, and I still experience it since I have a N4 still, there was some hardware limitation that prevented it from charging wirelessly with certain Qi chargers. Now I don't know if it was the Coil or the Hardware internals, all I know is, it doesn't work with all chargers, so why take the risk.

It for sure doesn't work with the Nokia DT900 which is a very common Qi charger.

Sent from my Nexus 5
[ONE General] 4nth0ny:
Interesting, thanks for the heads up but this wireless NFC charger is actually from the N5?

I thought that the NFC was not actually wired to anything, just an antenna that grabs data from outside the phone then wirelessly transmits it inside the phone to another receiver. Am I incorrect in thinking that the NFC antenna that is on the back of the phone is just a middle man passing along wireless signal?
[ONE General] DrunkFuX666:
The link you posted is for the N4 coil not the N5.

And no the NFC does not transmit to the phone wirelessly. In the previous couple pages you can see the 2 NFC tag points that connect to the phone to transmit signal. Also on the Nexus 4 coil picture you sent, you will see 4 metallic points. 2 are for the NFC and 2 are for the Wireless charge Coil.

[ONE General] etalocohc:
So I think I have done it. I rearranged the wireless coil so it can fit underneath the nfc coil. Then I cut the useless part of the nfc shielding so it fits tidily. Only problem is, now I have to charge my phone on the side. See attached!
[ONE General] DrunkFuX666:
That actually looks very clean... But when you say charge on the side... What you mean?

Also, what charging coil have you used exactly?

A problem I'm facing a lot is when putting the phone on charge wirlessly, although it shows charging on phone and charger, the phone itself is Not charging. I would attribute that to a low charge current I think?

Sent from my Nexus 5
[ONE General] 4nth0ny:
Finally we have a winner! What do you mean on the side?
[ONE General] etalocohc:
Because the coil is not angled vertically, I find that to get the best charge current, I have to set my phone like this. Max charge current is about 700mah, however I tend to get only about 500mah when charging.

I can set my phone on top of the charger vertically like normal, however because the coil is near the bottom, it looks a bit weird
[ONE General] etalocohc:
I used a generic 750mah coil I found on ebay. Interestingly, in my disassembly of the receiver, I noticed that there is a black pad that stops wireless charging and hence nfc. I wonder if someone could just remove the coil and put it between the nfc coil and the back plate?

[ONE General] burnski:
Awesome thread, subscribed.

The wife & I both have Nexus 4 and grown quite accustomed to the Qi charging. I was hoping to get the Nexus 6 but the off-contract price completely turned me off. I hunted down a invite and ordered an OPO last night. I'm not afraid to void my warranty by soldering in a Qi pad and im quite competant in my ability to do this mod.

My questions is, I read through the whole thread looking for the ideal Qi pad to use. Im looking for one that has the correct USB attachment because I want to try it out for a few weeks just stuck to the back cover before I make it permanent. I have found a few links, but I see alot of discussion regarding the output mA, as well as several that the sticker says one thing but turns out to be another. Has anyone found one with a high output (750-1000mA) while having the correct right-angle USB adapter?

Also in Canada we dont have Google wallet so I plan to remove the NFC to allow proper operation of the Qi pad. Thanks guys.

Here are a few pads I found in the thread, as well as through general searching ebay, has anyone had any luck with any of these?

I ordered three different ones that all advertise 1000mA. Once they come in I'll do some testing. I have a nexus 4 with the original qi orb as well as a couple of the lg wcp300 charging pucks and it usually maxes out around 850mA, so i figure if i can hit that with the opo and one of these receivers I'll have a good candidate for surgery to permanently install it like the OP has done.

Does this work even if you have a case on your OPO or how far away from the dock can you be?

I have used a coil with a case on... But I had set it up so the charging coil is between the back of the phone, and a diztronic case... Rather than the coil between the battery and back of phone, and case on top of that.

If i remove the stock nfc antenna to replace it with the qi, i wonder if i can use the embedded nfc in the SIM card instead.
[ONE General] DrunkFuX666:
I would imagine the phone would need the capabilities to be able to read the NFC in the sim... Dont think phones generally have that? I remember there were also NFC embedded SD cards once upon a time... But they died soon enough...

I just saw this article this morning... I wonder if we can try this charger...

http://www.phonearena.com/news/Tylt...e-screen-smartphones-like-the-Nexus-6_id62289

Here's the specs from Tylt's website:

http://www.tylt.com/vu/

"Tech Specs

Input: 12V / 750mA

Output: 5W

Length: 7.5 inches

Width: 3.5 inches

Thickness: 1/2 inches

Weight: 5.7 ounce"

Based on it being a name brand, I'm thinking it should output the entire 750MaH...

I may order one of these to try it out... but I need to figure out which coil to order. I want to keep my NFC if possible as well... so since that's the case, I'll wait for the updates from the above posters! :) Thanks guys for testing this all out!
[ONE General] CravingMender9:
I have the TYLT Vu that I use daily for Charging my Note 3 and Lumia 920. I will personally vouch for it and back it 100%. It is a bit on the expensive side, but it is a champ when it comes to reliable charging.
[ONE General] burnski:
The output is probably closer to 950ma. Ohms law states P=IV so P/V=I, therefore 5W/5.2V=0.96A
[ONE General] CravingMender9:
Don't forget efficiency and losses.

I'll check the current I get from it once I get home in the evening.
[ONE General] burnski:
I assume there is loss, but they advertise the output as 5W so that would already include any loss of the charger.

Whatever the eventual input of the phone is, will be a completely different number as well; like 10-20% less.
[ONE General] Adrian312:
do we have a winner?

Hi guys,

I just went thru all pages, but, correct me If I am wrong, we don't have a winner? My OPO is getting thru customs and I am already thinking to add Wireless charging.

Any recommendation for Pad?

Thank you,
[ONE General] CravingMender9:
I will always recommend the TYLT Vu.

I also have another 3 coil pad (I think it is called DigiYes 3 coil T300, $30) I got from Amazon.

That also works quite well till now.

As for receiver coil, I haven't received mine yet. I'll post when I get it.
[ONE General] etalocohc:
I am wondering if we need to use the pads from the nexus 4/5 (combined nfc and wireless charging) from looking at all the other attempts, everyone has been putting the full pad under the nfc. Now I know the wireless charging receiver and the nfc has a black pad in it for shielding. That shielding stops the signals from going through, so technically, if we take the shielding out, the pads should work together. I have yet to try this as I need to resolder my coil, so if anyone else is at this stage, it would be interesting to see if the wireless pad will work in conjunction with the nfc.
[ONE General] burnski:
I like the lg wcp300 pads. Verizon carried then in store and they sell for about $40 including the usb cable and the power brick.
[ONE General] CravingMender9:
TYLT

Update: My TYLT gives around 640-650mA to my Note 3 with the official charging cover (rated 650mA).

I am thinking with higher rated receiver, I may get much more.
[ONE General] DrunkFuX666:
With the higher rated receiver technically you SHOULD get more, but the problem is 98% of this generic crap from China Is not accurate and writes whatever the hell it wants to boost product sales...

It all depends on if whatever Is inside that packaging is actually a 1000mA receiver... Iv seen/had 2 strikes till now with the so called 1000mA receivers...

Sent from my Nexus 5
[ONE General] burnski:
which ones have you used? Have you found any that are actually >750mA? Id even be OK with that.

I use a 10' micro USB (with a 1.8A Samsung power brick) to charge my OPO at night since the included 3' cable barely reaches my night stand (forget even being able to pick it up while in bed). That 10' cable only supports about 600mA anyways so charge speed really isnt that important to me (as long as its charged in the morning). If im ever in a pinch where I need a quick boost then ill pull out the stock charger/cable.

I really miss the wireless charging I had with my nexus4 :(. I hope my USB qi pads come in soon...
[ONE General] Diablo2424:
The soldering part of your post got me thinking. Back in the day I remember having to connect two tiny dots on the top of my AMD Duron processor to unlock the multiplier to overclock it. Everyone on the forums had told me the easiest way, since soldering was out as the CPU was too small, to go buy rear window defroster repair liquid from an auto parts store. Essentially its liquid conductive that you can apply in any way/shap you want. I wonder if we can draw our own coils for charging/NFC to customize their size and shape to allow both to work. Just wish we could order extra back covers to test this out.

Just some food for thought. It could also work to repair coils that break and stop working.
[ONE General] jgrinst1:
The NFC antenna has to be an exact length to tune to a harmonic of the required frequency of 13.56 MHz, so I wouldn't attempt to make my own. Fixing a broken one, though, should work ok.

I believe spare back covers are available from ali express without the NFC antenna, so that's probably next on the list if the NFC replacement works.
[ONE General] etalocohc:
Hmm if your nfc coil is broken, then I guess you need a replacement. My nfc antenna is fine. I just soldered my wireless coil to move it to a different spot
