Introduction: How to Make an IR Blaster
In this Video I'm Trying to make an IR blaster.
An infrared blaster (or IR blaster) is a device that emulates an infrared remote control to autonomously control a device that is normally controlled only by remote control key presses. ... Another common use is to extend infrared signals in order to place remote controlled products behind closed doors.
I'm going to Make a IR blaster for Smartphones which will connect to your device using a 3.5mm Jack
This a Myth-buster instructable to prove that does the IR blaster for the phone work?
There are lot of videos regarding this stating it works,some say it doesn't work.
Lets find out if there is any truth or its just a Myth.
Step 1: Parts Required
1x 3.5mm Aux cable ( I had broken one lying down so I used that, You can alos get a standalone 3.5MM which can be easier
2x IR leds
small Piece of 6mm heat-shrink tubing (optional)
You will need Hot glue gun & a Soldering Iron
Step 2: Understanding the Led
I'm sure if you have dealt with leds then you will know hot find out anode & cathode. Nevertheless
I will tell you how to find out alway the long lead is the Anode(+) & the short lead is the cathode(-).
For reference check the images
Step 3: Connect the Two Led in Series
Connect the two led in series where in positive(+ Anode) of led 1 should be connected to the negative(- cathode) of led 2 & positive(+ Anode) of led 2 should be connected to negative(- cathode) of led 1.
Check the image for reference.
Step 4: Connecting the Leds
Please check the Image on how to connect the Led to the 3.5 mm Jack
Step 5: Final Finishing
After you have soldered it it should look something like the image shown.
You can use some heat shrink to to give good finishing I did't feel like giving a finishing as this was just a test
Step 6: Download the App
In order for this to work you the ZAZA remote App (https://play.google.com/store/apps/details?id=com....)
go to advance settings
Increase the Macro key sending gap to 1000 MS & turn on the audio reversal
test results prove that it works However there are limitations. Like range & audio Drivers of the phone.
This is DIY IR blaster is not compatible with all the Handset if you have good sound driver in your phone it will work. For some reason it didn't work on my other sony phone.
My suggestion would be to try and make one and check if it works and then if you want you can buy
from the link
You can check My Youtube Video for the making.
We have a be nice policy.
Please be positive and constructive.
Will it work on Moto g4 plus
I bought some 940nanometer infrared LED emitters and tried it and didn't work. I was about to buy one prebuilt infrared blaster but gave up because I assume the Moto G4 Plus has some faulty sound driver somewhere along the way.
i understand completely. What I am not understanding is in these 2 pics it looks as though the bare soldered pairs are braided together.
What I’m trying to understand is that after soldering the leds in sequence to the individual + & - you then twist both bare metal pairs together. Am I missing something?
You just have o connect both leds in + & - series and then connect it to left and right pin of the aux pin
WE NO NEED THE LAST OR DOWN LAYER RIGHT?only the first 2 LAYERS WE NEED TO CONNECT THE IR LED RIGHT.????
LOOK THIS PHOTO
You don't need to use the ground pin
Does we need a extra battery for it blaster.???will it work in one it led??
No you don't need any battery
