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.

- 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.
