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


Step 6: Download the App

In order for this to work you the ZAZA remote App (

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
