Introduction: How to Make an IR Blaster

About: My profile is about making most use out of something and optimum utilization of resources available,dedicated to D.I.Y (Do it yourself) Projects.Easy Hacks,DIY Experiments, Myth Busters & More

Hi Everyone,

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

Video

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

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

    Please clarify what you mean by right and left. Because turn it 180°and right and left change so unintelligent people should never mess with electronics and electricity. If you know anything about leds then you know that the long leg is the anode (+) and the short leg or the leg closest to the flat side is the cathod(-)

    I miss having phone that came with inferred leds built in to them for various reasons. They came in so handy.

    Find the flat side of the led. The leg of the led closest to the flat spot is the cathode(-)

    Answer 1 year ago

    It is really because of the AC output as during any of the 2 cycles at least one led will work

    i made my own ir blaster by following this tutorial.
    working on my samsung galaxy J7 Prime.

    i use 2 different ir LED,
    1 from my mother radio tape remote
    1 from broken fan remote

    total cost of this project is = less than US$0.25 , or maybe i can say this project is FREE.
    using all my useless broken electronic and now i have my own ir blaster.

    Hi!
    In the product sold, the head of the jack is made of plastic. Do not need all contacts?
