Don't like your little brother's TV channel selection? Hate the volume your wife sets the stereo at? Want to just annoy someone? This circuit does all that and more by jamming most IR remote signals. The circuit releases a flood of pulsing IR light that confuses the reciever by corrupting the data stream.

Notes

Email Carl with questions, comments, etc.

You may need to adjust the value of R3 for the right frequency. A pot can be used.

You may only need one IR LED.

It goes without saying that this circuit should be used with descretion.

The value of R5 depends on your supply voltage and LED. For a standard 4.5V supply and standard IR LED, use 22 Ohm as specified on the parts list. This forum topic covers this resistor as well as a few other issues with the circuit.

hello i made one when you look at the ir led through a caera u should be able to see it light up should it be flashing or continously on mine is continosly on and were must u stand wat frequency does it jam wats its range pls email me with all of the informatrion about tit i need all info pls

A pot of what resistance range should be used in this project

Hey stupid, de-solder one led leg problem solved!

in place of Q1 &Q2 which other transitor may be used

iiiddd IR Remote Jammer Saturday, April 11, 2009 10:54:24 AM

what is the resistant of the pot? maximum and minimum

abd IR Remote Jammer Sunday, March 29, 2009 3:36:01 PM

can you just tell me how is works? any remote can do the job?

The project is really good. But anyone can tel me it is fully working or not. Because 2 times I tried but failed. Please reply me as soon as possible.

I am a beginner in electronics and I am interested in this particular project.Could you tell me the functions of each component?

Sir how can i increase the range n can we increase the frequency by replacing the IR LEDS wiv the higher ones??
