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.

Schematic

This is a schematic of the IR Remote Jammer

Notes

  1. Email Carl with questions, comments, etc.
  2. You may need to adjust the value of R3 for the right frequency. A pot can be used.
  3. You may only need one IR LED.
  4. It goes without saying that this circuit should be used with descretion.
  5. 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.

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.

You guys make me sad. A pot is short form for a potentiometer, basically a variable resistor. If you don't know that or want to try to build this and you don't know what the different parts do, or even where to buy them, then I suggest not building this. Use your head, i.e. use wikipedia and google. Try www.abra-electronics.com for most parts at very decent prices

A Potentiometer or "pot" is a type of resistor. The volume knob on a stereo or a light dimmer are a couple examples I can think of.

Is it possible that this similar technology (IR LED's used in Wii sensor bar array, when provided voltage) could be jamming our Insight cable remote? Nintendo thought my question to them about this issue was unusual. If the IR LED array is getting voltage in standby mode and emitting, it would seem feasible to me that IR interference is occuring.

What you see here ARE the full details. The circuit is extremely simple and just flashes the IR LEDs at a certain frequency, so the TV's IR reciever is flooded in IR light and can't detect the remote control. You can't expect the author to write your term project for you.

Forgot to say - the roadworks ones ran at about 1 Hz - a bit slow for an IR remote. But it has to be that slow to be seen behind full-beam headlights. Just like an IR reciever can see the remote even when your 2KW heater's going full blast and the sun's shining in - it ignores the constant light, just sees the changes. But I guess that's obvious.
