HOW TO MAKE IR BLASTER FOR ANDROID AND iPHONE

Create a Infrared transmitter for any portable mp3 device, ie phones, music players etc.
This tutorial is for creating the Infrared transmitter only.

Can be used with  android App zaza remote Download link

The way this transmitter works is it sends infrared on and off signals from the audio playback coming from your headphone jack. Having saved an audio file with the correct on and off timings, you can play back this audio track through your portable music player and trigger infrared devices.

This transmitter works better with a WAV audio playback, however this has been successfully tested as an MP3 audio track.  The WAV track generally produces  a clearer signal as they can playback a 38 KHz modulation (Infrared frequency rate), by dividing the frequency between the two stereo channels. 19 KHz for the left channel and an inverse 19KHz signal for the right.

To better illustrate this the left channel will play an on and off signal ..
0101010101
The right channel will produce the in-between signals for the off time ..
1010101010
Therefor each channel will take turns producing a infrared signal creating a higher frequency rate, equal to that of an infrared remote control.

The Items needed for this DIY project are ..
1) Infrared LEDs  2x
2) 3.5 mm stereo audio jack

3)some heat shrink tube

4) A hot glue gun

5)soldering iron
