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.

I was wondering if anybody knew why a remote control for a tv gives 38khz I know it's becouse the reciever is attuned to this but why did they pick 38khz and not 40 or something
