|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.|

|sir i like this kind of project.sir can we use any other kind of transistor instead of this mention above?|
|i have made this and its working .... thanks for sharing just want to know if there is any relation for finding the exact values of the variable resistors to be used instead of R3 for a specific frequency.... or a frequency dependent formula you can provide me with the basic calculations ... regards|
|Would this work in jamming a Sumo Robot's IR sensor?|
|sir, can you please tell me transistor equivalent to those two 2n4403 and 2n4401, because it is currently not available in our city.|
|Is this model#: CML105M50 from radioshack an appropriate capacitor for C2 in the circuit? And what is the desired ma and voltage specs on the high output ir leds?|
|the projects WORKS!!! just be carefful when connecting the transistors!!! I made a mistake whit Q1, but then i cheked the datasheet ;)|
|Does the jammer really work? I dont mean that in a rude way but i built the jammer and it doesnt work. If it does work than what are the common problems that might be the reason mine doesnt work.Also, is there a variable resistor in the jammer? If so where is it on the shematics? sincerley AJ|
|USE A 10K variable resistor instead of the reg. 10k, this way you can change frequencies instead of having the circuit just set to one. *Also I removed the R1 component because the lights don't even come on unless you do.|
|what is the expression for freqency of the circuit|
|Here is a microcontroller based IR Jammer. I bought the kit version and assembled it in about 15 minutes. It kills everything I have tried it on! Here are the details. http://www.instructables.com/id/IR-Remote-Control-Jammer/ Here is the kit (or you can just make your own from the plans) http://alan-parekh.vstore.ca/ir-jammer-kit-p-116.html|
