红外遥控器干扰电路 IR Remote Control Jammer

By Carl
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.

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.
