[Nexus 4 General] MerynGoesAndroid:
No, the headphone jack does have enough power to feed the IR-LEDs, unless you expect it to work at 10+ meters! Altho, since you salvaged LED's from older equipment, these may consume more power than you'd expect. Best thing to do is to buy some new, low-powered LEDs.

While testing them, dont forget that you have to throw some sounds out of your jack first before you check the LEDs, afaik the jack does not output anything while idle.

The external battery can work, but it can take some time and thought to get the right circuit working. I'd suggest you take a look at this (product here)

And again, please check if you wired the LEDs correctly! The LEDs should be wired mirrored, so that power from the left earphone will power 1 led, and power from the right earphone will power the other led. Ground should not be connected.
[Nexus 4 General] ttheodorou:
so does it work in small distances (f.e. 1 meter)?
[Nexus 4 General] hercules16:
It work with moderate wav files and new diods the distance is a about 3 meters.
[Nexus 4 General] MerynGoesAndroid:
Have you got it working now?
[Nexus 4 General] hercules16:
Yes.Thank you for the idea with new diods maybe an old recommend more power.
[Nexus 4 General] MerynGoesAndroid:
May I ask, how have you got the leds connected to the 3.5mm jack? From L/R to ground?
[Nexus 4 General] hercules16:
The scheme is +led- and -led+ and regular and one opposite.
[Nexus 4 General] MerynGoesAndroid:
Yes but seeing from your pics youve connected them to Left or Right and Ground. Have you changed this back to L&R or did it work with Ground?
[Nexus 4 General] hercules16:
Yes I was changed to L/R in the picture is invalid . I can make new pics in Saturday and Sunday and will make little guide .
[Nexus 4 General] MerynGoesAndroid:
I think a guide would be greatly appreciated around these forums, and I'm interested in your end-product. Looking forward to the pics!
[Nexus 4 General] hercules16:
It would be great anyone who use SDK to build a simple apk.
[Nexus 4 General] MerynGoesAndroid:
Since there are a lot of different devices controlled by infrared, and many of them uses different IR commands, it will be hard to make a simple app. The best I've come by is the app by IRdroid, it has a basic database with some standard commands. Give it a go! (dont forget to update the database first).

If you plan to use it for a specific device, then yes. You can record your standard remote and save the commands, make a simple GUI and connect the commands (after you made them to wav) to the right buttons.
[Nexus 4 General] hercules16:
Thanks.
[Nexus 4 General] ttheodorou:
i am very interested in your little project and i would like to see a tutorial from you or simply a paint picture to show us how exactly you made this possible.

This is how you should connect it (resistor not needed, but added for extra protection).

Dont directly solder them on the headphone pins like above, solder them on the inside (where normally the wires come out).
[Nexus 4 General] ttheodorou:
thx mate. i will try it when i find the infrared leds.
[Nexus 4 General] Clem29:
Can someone do a step-by-step guide to do this? Thanks in advance
[Nexus 4 General] ijustzeke:
Please make a step-by-step guide. If only you guys have time.
[Nexus 4 General] MerynGoesAndroid:
I'll make one when I have some free time (probably tomorrow or the day after).
[Nexus 4 General] ttheodorou:
i did this and i can make a tutorial, BUT it doesn't want to work! ir droid doesn't seem to be compatible with this. has someone made it work? what app did you use?
[Nexus 4 General] MerynGoesAndroid:
I did use Irdroid, but neither did it seem to work for me. (Be sure to put your volume all the way up, it gives you more power on the jack)

However, it DID work on my tablet with this app. (only <1meter away from the television, keep this in mind), so it seems that my tablet has more power output on the DAC than my phone has.

Be sure to use low-power LED's, you can even make an extended module with a battery to boost the signal (ill include this in my tutorial).

If irdroid is not compatible with your television, you can look for other apps or even look up your tv commands and import them to irdroid (will also be in my tutorial). you can find the tv commands here.
[Nexus 4 General] ttheodorou:
the leds doesn't seem to work. that is my problem. i tried it on my n4 and my older phone and nothing. maybe i need other leds...

edit: i checked if the led was working with a phone camera. it seem the led are dead :(
[Nexus 4 General] MerynGoesAndroid:
The light coming from the leds will be so low it is hard to see. (i'm not even sure a phone camera can pick up this weak light) so it might seem that they dont work, while they actually do. If you choose to test them this way, make sure you do it in a very dark space.

What you can do to test the leds is connect a battery to them, using some wires and check again with your phone's camera. With a 1.5V or higher battery this should be easily visible.

What LEDs did you use, did you recycle some from older devices? I suggest using new ones ;)

If you're into stuff like this and have experience with development boards like Arduino/Raspberry Pi you can also look into projects for these platforms. They can give you more power than your phone can and altho it wouldnt be exactly like a phone remote, you can set them up with bluetooth/wifi to use your phone as a wifi-remote. This way your commands will go through bluetooth/wifi to your boards, wich will then send the infra-red to your television.
[Nexus 4 General] ttheodorou:
i used new leds i bought them today.

the only reason i did this project is because i have a tv/computer monitor with touch buttons (that i have to press them 3-4 times to do something) and i lost the remote! ****ing touch buttons, i hate them! i will try with a battery if i can fin a cable and a battery!
[Nexus 4 General] MerynGoesAndroid:
Haha, wouldn't it in that case be better (and prolly cheaper) to just buy a cheap universal remote that can just use power on/off, channel up/down and volume? I can buy a remote like this (looks like a child's toy tho) for €0.75, ~$1 at a budget shop nearby. I can see a IR module get lost easily as well, especially since you wont be carrying this thing around all the time.

Do you have any specifications of your LEDs? Power usage?
[Nexus 4 General] ttheodorou:
yes it would be cheaper but i need the remote maybe twice a month and i would probably lose it again because on my desk i have only things that i need. on the other hand, something that small, i will store it in a box with pens and other small stuff and i will not lose it.

i test it with battery and both led are working. so it must be that the nexus is underpowered
[Nexus 4 General] MerynGoesAndroid:
Just checking for the sake of being sure, you did try them within a meters range? Also pointed the leds towards your monitor's receiver?

Volume is maxed? You found your TV's commands in irdroid/lirc database from 2 posts back? Your LEDs are connected the way they should?

See if you can get any specififications on your LED's. If they are packaged, see if it is printed on it.

These are the ones I used. 1.5V, 20 mA (0.030W) and worked with my tablet.

You should be able to find 1.2V LED's which could work better. Be sure the wavelength is 940nm!
[Nexus 4 General] ttheodorou:
i don't have the exact specs of the led except it is infrared led.

i manage to make it work with my old phone for about 30 secs or so. i think my problem is the 3.5 jack. it doesn't fit well in the phone and i need to push it with force. i will try again with a new jack and possibly new led if i find something new that i know the specs and are the same or lower than yours. unfortunately the store that i bought them didn't know the exact specs so i have to locate another store.

thx for your help so far. really appreciate it. today i have free time so i will make a tutorial on how i constructed the ir blaster for everyone else
[Nexus 4 General] MerynGoesAndroid:
Small note here, you should not put the tape between the 2 leds, but between the legs of 1 led. The tape is there to prevent short circuit. Right now you have taped the Cathode and Anode of 1 led, leaving the other LEDs Cathode and Anode still open. If you push these 2 legs together, you will still cause short circuit.

The trick here is to tape the Cathode of LED1 and the Anode of LED2 together (you soldered them together so it shouldnt be hard to access them. This way you wont be able to cause short circuit.

The way you taped it, you will still be able to short circuit them, so the tape is rather useless here.

Other than that, great tutorial!! OP should include either a quote from this post, or a link to this post so people that come to this thread wont have to search
[Nexus 4 General] ttheodorou:
in the morning i will tape it better take a picture and i will update the tutorial. i am thinking of moving the tutorial to the android section of xda so it is more accessible.
[Nexus 4 General] rohit297:
So it doesn't work with our nexus 4, am i right??
[Nexus 4 General] MerynGoesAndroid:
Wel it should. I just did a quick test with mine, but this was on stock with no mods and not the best LEDs.

If You have lower powered leds and some volume mods (For louder sounds) it should work.

You Can always make an amplifier which should always work.

I will Make a newer and better version with sounds mods when i have some more free time and post my results.

You can always just try and see if it works. Its cheap and doenst need much phone modifications
[Nexus 4 General] hercules16:
Hi last time i fix the older one and it start worked but with poor signal ,now

I bought http://www.ebay.com/itm/261340819757?_trksid=p2060778.m2749.l2649&ssPageName=STRK:MEBIDX:IT

I soldered them with jack and what ? They can't work WHY ? I use one scheme in this forum i connect 1 led ( + ; -) 2 led (- ; +)but they wont work i don't know . Can you help me with my problem i want to make this thread important because many people want to make Ir blaster for their smartphones .
[Nexus 4 General] MerynGoesAndroid:
The LEDS from your link look fine, I doubt they are the problem

Theres not much info youre giving me here, so at this point it could be anything.

Could you explain to me how you tested, did you test the LEDs with a battery? You older ones worked, do they still work?

What app were you using, are you sure you got the right TV model?

What do you mean with "poor signal", at what distance did it start working?

Can you give me some pictures of your blasters?

If your previous setup worked, I doubt you will get better signals with these new ones. I had a maximum range of 1m with my LED's, and theyre no different from yours. If you want good ranges (~10 meter?) you will have to build an amplifier with a battery. Irdroid has a nice schematic on how to build this, ill include it in this post.

[Samsung Galaxy Nexus] wellwhy:
So I decided to revert my GNex to stock, using the toolkit by SkipSoft. I've used it multiple times, no problem. This time, it worked fine. I rebooted, downloaded a few google apps, and opened youtube. Tried to watch a video, and the screen ****s out on me. Things switch around, hard jittering, looks like someone took scissors to a piece of paper and cut lines down the sides. Looks like some sort of mosaic. The screen gets really bright and gamma goes up, and then pop, it dies. I have tried to reset it again but whenever I get into fastboot the gamma gets extremely high and it turns off. What just happened? Is the phone about to die? I can't find anything similar on it.
[HTC Desire 500] teufelschultz:
Hello,

first of all sorry for my bad english. I hope you understand

My Desire 500 means for some time loads and this is connected although no loading cable. This state sometimes decreases after pair of minutes after depart of the loading cable, but the also hours sometimes go in such a way.

Furthermore the accumulator in spite of not use does not hold yet one day. The mobile phone lies about only, WLAN in, Autosync in. In the morning at 7 o'clock 100%, evening 21 o'clock only 10%.

I have already exchanged the accumulator, both mistakes have remained.

The mobile phone has fallen down to me, has torn the display, but still usable. Can this be by the fall passed?

I take in I by the fall all guarantee claims has lost?

Greeting

Robert
[HTC Desire 500] ufonek:
I do not understand much. But I suppose that your problem is in rapidly discharging battery. First try factory reset. If does not work, then it is probably a bug in the hardware. The guarantee in case of a fall probably forget.

Try Xposed Xperia by serajr.

In latest version (v.3), you can add sliders tab and something similar...
[Xperia Z2 Themes and Apps] dryla:
Best is Gravity Box (KK), this is module, so You must have Xposed Installer and installed Xposed framework.

In statusbar options is swipe brightness function, just swipe from left to right for brightness :)

Now i tried xposed with xperia V Mods.

But i didnt want to test the v3 because it is in beta status and wasnt offered to me in the framework app. There only was the v2.6.1

With this version i am only able to change a few for me unimportant options.

So im going to try the other proposals.

But thank you anyway

You can always go to xposed/Xperia xposed module/settings (slide to right) and choose

[Xperia Z2 Themes and Apps] Paweleek:

[Xperia Z2 Themes and Apps] LaLey:
Since i've installed the framework and gravity box, i noticed a very high battery drain.

Before the installation it was easy for me to use the phone 2 days. Even because the drain over night has been nearly 0-1%.

Now the battery lasts only 1 day and loses 12-13% in the night.

In the gravity box i only changed these options:

- Brightness slider on taskbar

- flashlight on lockscreen by volume key

- flashlight by long pressing recent apps softkey

- long press back softkey to force close an app

- skip track by long pressing volume key in stdby

- CRT shutdown animation

I would like to remove gravity box, xposed and framework. To proof whether the drain comes from this stuff, or from something else.

Can i simply uninstall those apps oder do i have to reset something?

[Xperia Z2 Themes and Apps] Rantrave07:
you can deactivate them from xposed app. if you want to completely remove them you can uninstall directly. nothing special.

[Galaxy Note II Q&A, Help & Troubleshooting] Pellucid.E:
So, I recently "rooted" my phone. With the aid of KingoRoot. Which was a bit troublesome at first cause I didn't exactly know how to handle the forever boot loop but it didn't take me long. Anyways.

After I rooted I couldn't use Samsung's Screen Mirror feature. After a couple of quick searches, I learned that I couldn't use the feature because I rooted my phone. It displayed an error which says something about a hardware issue. I want the feature back.

So I decided to unroot. I thought I did. Using, again, KingoRoot. But the error was still there and I couldn't use the feature.

I misread my android version number As 4.2.2 so I decided to update my phone as well (It was actually 4.2.2.). When I went to the software update menu and pressed update now and pressed okay, it says "The operating system on your device has been modified in an unauthorized way. Try downloading software updates using Samsung Kies on your PC, or visit a customer service center."

So I thought the root wasn't fully removed. Once again, I rooted my phone using KingoRoot. but this time used SuperSU to unroot. This also produced the same result and I still have not been able to use the feature.

I tried to use Kies. Tried Firmware upgrade and initialization. Didn't work. Tried several times. It always "fails",

My friend suggested that I use Odin to flash the stock firmware. So I went to Sammobile. Entered my model number and found lots of firmware and was confused cause I couldnt find matching firmware. Anyone know how I could get the right firmware? Or a better way to unroot?

I used "*#1234#" To get this information: AP: N7100XXUFNE1, CP: N7100XXUFND3, CSC: N7100XAFNE1.
