Making an IR Blaster for an Android Phone - Will it work?

In this video I make an IR blaster that can be connected to an Android smartphone and used with apps such as "irplus WAVE". This allows the phone to be used as a (short range) universal remote control to control a multitude of devices. It also allows the user to enter custom, raw codes which is something that can't be done with most universal remotes which rely on lists of codes that are programmed in at the factory.

Connect it to a Bluetooth headphones adapter, mount it just in front of the TV and you have no need to hunt for the remote!

[@aleksandarristevski1906]

Did this work on all tv

[@minhbeo0909]

Connect what to the bluetooth headphone adapter?

[@ChrisKirtley]

Crazy that they don't put Bluetooth in TV's!

[@Coolkeys2009]

A -Remote- control :-) You may as well add a couple of transistors plus a battery and make it really useful.

[@prathameshlad397]

Coolkeys2009 yeah I have done that but still sight increament in the range....(10-15 feet) Hold on....you said couple of transistors. I tried only one....can you please tell me how to connect multiple transistors..?....

[@techtrashing]

Air conditioning in hotels on holiday is often a chargeable luxury. Sling this in your travel bag and save yourself 20 euros a week.

[@techtrashing]

There is an APP called Pure universal control. Has a massive database of vendors. I was able to do exactly this on a Galaxy S5 which had built in IR. Its a solid use case and I am tight as a ducks arse. ;)

[@tamerx5]

I think this is a thief

[@ShivamJha00]

Most of the hotels here have separate AC and non AC rooms

[@nickrr3626]

I used to have a OP2 as well, great phone! I picked up the V20 and I got so excited when I found out it has an IR blaster! Sucks I didn't see this video earlier i could've had this feature on my OP2

[@similarlydifferent7548]

Great... Something else I can spend hours looking for just like the remote. Why they are no longer in phones I will never understand....

[@prathameshlad397]

Have you tried this with a bluetooth adapter(audio reciever) ....so we dont have worry about the range...

[@SultanOfAwesome]

I hate that samsung removed this feature from their phones.

[@Av-ks8uc]

HTC also did. I loved it on the M7, but now it's gone :(

[@Misterbeff]

I have an M8 and it has infrared

[@Gravarty]

Yeah i loved this feature on my S6.

[@theabstractor1297]

LG did it too :(

[@tejasbhandare251]

Atleast samsung has headphone jack

[@deblish]

amazing, you are helping me to access to a hidden menu on my lg cx since I refuse to buy a new control just for that, I'll follow your lead, thanks pal

[@mephitusincognito7918]

this seems like the sort of thing one could plug into a soundcard and do even more with... esp with photo-transistors on the line-in... ah the possibilities :)

[@giovanninervi9380]

Many smartphone have jack 3.5'' with 4 pins: mic, gnd, r audio and l audio. With jack with only 3 pins make a short between mic and gnd. Is it ok or can broken my phone?

[@comedyclub333]

A bit late i guess, but still: Shorting mic to ground is no problem. As GND is the reference signal and the microphone is set to GND no potential difference occurs (this basically means no audio signal). Remember: Your phone will not force the mic pin to a specific voltage as it is an input pin, not an output.

[@oggyosbourne]

That one a didn't know about. I use the remote feature in my Huawei P10 Plus for it have a IR Blaster :)

[@Chaoddity]

Loved it. Quick project i could make with a few leftovers. Now i can control my tv AND my kodi with my dumpy phone. Gotta say though... the range on this is depressingly short. Sincerely considering transistor, battery, or at LEAST a reflective cone

[@prathameshpatil9760]

I cant make it

[@luis96xd]

It must be two InfraRed LEDs obligatory?

[@aycebenzsalud]

Try using the same pinout bit with one IR led so it works even farther It also made it universal sk it works on both android and ios too. For ios try fingertip remote international for some tvs If you want more models like old ones.Then try Zaza remote (uni tv remote for ios users Might be region locked)

[@user-nf4hq5li7n]

Can i make remote with 1 single ir led?

[@meetoo594]

I have a little rc helicopter that uses a premade version of this. It doesnt work very well, the heli suddenly whacks up the throttle or goes in a random direction resulting in a crash. The little box does work quite well as a tv remote though.

[@khaledbmw99]

any device adequate this method there is internal program to produce output power and also program apk to make the the saved data of remote is converted to pulses so you can not do that in normal device you didnt have the apk program and also the power is in micro volt if you masseur by avo meter i try to coupled with transistor c1815 it not response even i make the lg in star pulse is maximized by tvc 2 time in max level audio converter it not work

[@daddytwins2003]

Is there a way to add an amplified circuit to boost the voltage to the led and increase the range?

[@camerongray1515]

+Jason Scheuren was going to look into this at some point, it's just pulses so I imagine you could do something quite simple with a small battery and transistor.

[@binarymodeandroid9840]

Hey, i just stumbled across your video. Would you agree that i create a link to your video to the irplus website? Maybe it is helpful to others who want to build a blaster ;)

[@camerongray1515]

That would be fine! :D

[@1000wolfdogs93]

Hey, +Cameron Gray, I've seen alot of these tutorials, on how to make your own IR emitter, and I've only ever seen people using two LED's to make one. Is that really quite absolutely necessary, or can I just use one; also, what's the difference?

[@add124nad]

2 LED'S let's you connect to more appliances and you can go further if you olny have 1 you cant connect to some appliances

[@add124nad]

Correct me if im wrong

[@buntysaini5649]

can you make ir learning remote code device with audio jack in Android ..... possible......

[@MrAmulyamishra]

Hey Can i use this blaster with mi remote.

[@illyasvielgoddenflash2340]

almost Mi smartphone build in with IR blaster ..i can control TV,TV Box, Air-conditioning,Blueray player,Home theatre, Humidifier within 3 meters away.

[@amitpal6221]

My tv works fine with no problem but it have a single issue, it performs some unnecessary functions with other devices remote like, set up box, other tv remots, AC remote, just take an example, whenever i change my channel with set up box remote, volume of tv increasing simultaneously, when i try switch to channel 4 with set up box remote then simultaneously tv switch off, when i press signal button from from set up box, input dialog box open(tv, Av, hdmi, usb etc option.) Can u tell me, what is wrong with my tv? Tv details, - Sanyo 49 inch android tv Model no. - XT-49A081U.

[@ccalhoun3908]

I love your accent.

[@edzams]

can I use any led diode at all or does it have to be from an old remote control device?

[@alirezakh739]

thank you cameron gray. i reallly enjoy your work and video. i have question. why you use two irled rather than one? and what was the name of that glue that you used? was it tipycal or else? and what is good for use with electrical devices?

[@user-fh2fm7vr4m]

It's so no matter the polarity one of the LEDs lights up.

[@bitrot42]

One flashes on the positive half of the audio waveform, the other on the negative, so you get two flashes per cycle. This way, you can get 38 KHz pulses out of an audio signal that's band limited to 20 KHz. Pretty clever!

[@abuchaa]

Amazing. Did the Scotts invent the remote control aswell as the t.v. gonna give this a go.

[@heitor5998]

You could made it smaller, with no box. I thought the box was housing some kind of circuit.

[@camerongray1515]

I could have done but it would have been harder to show on video and for something like this I'd rather it wasn't so small that I'd lose it immediately, at least at this size I can stick it in a drawer and find it again relatively easily.

[@user-tz7vy3pb9x]

I want receive signal from a remote control and save them in my device as irplus files Is it helpful ? I mean my phone have ir sender but haven't receiver

[@jonfoxsv1]

En Samsung con android 9 el ir remote 3.5 no funciona mas. He buscado pero no encuentro solución a esto ni porque del problema.

[@minoxidilexperiment769]

I like your videos , you are very intelligent dude and I find interesting all these stuff, keep it up

[@abdalnablse10]

It didn't support my TV or my remote and my TV is Sony bravia KLV-32BX300 and my remote is RM-GA019 but the two ir LED that are connected to my phone are working so I search on Google for the lirc files but no luck...... somebody help me please

[@RASHiDALi143]

I tried but not work with my Vivo Y21.... ...

[@DAVIDGREGORYKERR]

A NOKIA 6288 Slider phone would have the IR Laser Communications which would have been the way to go.

[@comedyclub333]

Is the second LED necessary? What purpose does it serve?

[@add124nad]

Well for first if you only have 1 LED some appliances won't work so I recommend 2 LED'S

[@nozmoking1]

Why 2 LED's when remotes have only one?

[@chackot.j4708]

Better intensity=more range

[@ranakartik7935]

In camera IR have to light but that is absent in video,(I am not mad)

[@camerongray1515]

Cameras have IR filters which block most IR light. Some are better than others which is why you can sometimes see a faint glow from IR LEDs on cheaper cameras/smartphones. The camera I'm using here is pretty high end and has filters this will block out practically all of the IR light. Night vision CCTV cameras have switchable IR filters so they have a filter in place during the day to block IR then can move the filter out of the optical path at night so that light from the IR illumination can pass through.

[@inse001]

Don't mix up IR and UV!

[@camerongray1515]

Well that's embarrassing, guess I must have been half asleep when I wrote that reply! I've corrected it now! 😉

[@davelowe1977]

You could have dispensed with the box and mounted the LEDs in the back of the jack plug.

[@MarmosOfficial]

The yellow wires need tu be positive or negative?

[@camerongray1515]

Since you have a pair of LEDs in inverse polarity from each other, it doesn't really matter - no matter the polarity of the incoming signal, one of the LEDs will light.

[@MarmosOfficial]

@@camerongray1515 oh ok but i do this and none led light

[@krillinwinnin4331]

powerful

[@AL-HD]

But why 2 led?

[@udaykarthikeya]

One Led operates at 19kh per second where as most of the ir communication systems operate at 38Kh per second ...... When you use 2 Ir LEDs Then it doubles the 19 kh so that the whole ir blaster system can operate at 38kh per second !

[@NAWAF-vc1px]

@@udaykarthikeya amazing. thanks for the answer. How do you know so much about this topic? I would love to learn more.

[@udaykarthikeya]

@@NAWAF-vc1px I got to know about it when I wanted to make an IR blaster myself !so I searched online and learned about it !

[@AlMa-qb3uc]

does it ir blaster work on all phones? if it does not work on a phone model, can any driver be installed to make it work?

[@camerongray1515]

In theory it will work on any device you can connect 3.5mm headphones to as it just works using an audio signal. That said, it uses the audio signal to power the LEDs so it really comes down to luck as to how powerful your phone's audio output is, some are better than others. For example, in this case, it worked but only over a really short range.

[@x3n0n.m]

Hi ! irplus still works with inbulit ir transmitters, or only from jack out ?

[@camerongray1515]

There's two separate versions of the app - "IRPlus Wave" is for an external IR blaster connected to the 3.5mm jack whereas "IRPlus" is for phones with a built in IR blaster.

[@x3n0n.m]

@@camerongray1515 Thanks. 😃 And how can I convert a binary data code to LIRC ?

Give the link of infrared led

[@alicomando1195]

what is the purpose of using two IR Led instead of one ?

[@lucianistoc1264]

since it uses an audio source,it uses the left and right stereo channels to send the signals

Two ways to check if your Android phone has a an IR Blaster: kzbin.info/www/bejne/pmOXmJeeYs-mjqc

[@DJLion1234]

i built it, but it isnt working. Both leds are working, but they are way too weak. Im using a oneplus 3t. is it outputting too little voltage?

[@dizzy210jd]

Can u test them? Each LED? His on this video is weak af. lol I made a super remote for my microwave and washer. What plays an effect big is really like he said. Angle is a lot. But u need a tester to check and see for sure that u have it all hooked together right.

[@dizzy210jd]

I missed that u said 3 I would aim for 3.5 low anything above just get better.

[@dizzy210jd]

If all fails look up "home made bluetooth receiver". Different blueprints almost same result. Light travels faster than sound. That's why this method is better than a Bluetooth receiver

Ir is a shortcut for infrared

[@simontay4851]

My android tablet has an IR blaster but my phone doesn't. I think I will build this.

[@illyasvielgoddenflash2340]

just buy Mi smartphone.. almost of them build in wit IR blaster especially Redmi devices. and could control within 3 meters away without obstacle.

[@ShivamJha00]

Or just buy a remote

[@asianbbqdominator1560]

So can i use a full bridge rectifier instead of 2 LEDs?

[@mohamodzclipzzofc5184]

I really can use it on any tvs?

[@camerongray1515]

In theory as long as the TV uses an IR remote and the IRPlus Wave app has codes for the device available. Only risk is that as the output of this is pretty weak, you may have issues if the TV's sensor isn't particularly sensitive. It's worked on every TV I've used it with, however I've often had to hold it up right against the sensor.

Yes, I don't produce fake content. Although it's pretty dependant on your phone and the LEDs as to how well it'll work.

Cameron Gray don't know how you deal with it haha. it would drive me insane

[@user-hh9eh9bu2d]

do you need wifi to do this?

[@nickrr3626]

No it uses infrared which is a light ray the human eye can't see. The bulb emits infrared light rays in pulses/bursts and the TV has a receiver which recieves the rays and demodulates them. This is a technology that most remotes use, the problem is you can't use it from anywhere and the remote has to be pointed at the TV for the light rays to be received. This is why we're starting to use Bluetooth or wifi so the remote works from anywhere. However IR is pretty simple and easy to work with which is why it's still around.

[@lscmore3877]

Fake

[@camerongray1515]

I do not produce fake videos, if it is not working for you it may be due to the audio output power of your device, the current/voltage required by the LEDs you've used or the sensitivity of the IR receiver on the device you're trying to control.

[@himanshu3v]

Not working bro...👎

[@camerongray1515]

Assuming the wiring is correct, make sure the volume is up full on the phone and you're holding it up against the sensor on the receiving device (also try controlling different devices with different remotes in the app). It also may simply be the case that the LEDs you're using requires more current to operate than your phone can provide.
