Remote Control IR Jammer


Remote Control IR Jammer

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.

  1. You may need to adjust the value of R3 for the right frequency. A pot can be used.
  2. You may only need one IR LED.
  3. It goes without saying that this circuit should be used with descretion.
  4. The value of R5 depends on your supply voltage and LED. 
  5. For a standard 4.5V supply and standard IR LED, use 22 Ohm as specified on the parts list.
