TV remote jammer
Description.
Here is the circuit diagram of simple but highly effective TV remote jammer circuit. Most of the TV remotes have 38KHz operating frequency. A flood of IR beams in the same frequency can easily confuse the TV receiver and this is the operating principle of our jammer. The circuit is nothing but an astable multivibrator based on NE555 IC. The output of NE555 is amplified using a PNP transistor SK100 to drive the IR LEDs. Not only TV remotes, but any IR remotes operating in the 38KHz frequency region can be also jammed by using this circuit.

Notes.
- The circuit can be assembled on a Vero board.
- Use a 9V PP3 battery for powering the circuit.
- Mount the IC on a holder.
- POT R4 can be adjusted to exactly match the jammer’s frequency to the remotes frequency. This adjustment is very essential for effective jamming.
nasıl çalışır ben devreyi yaptım amma çalıştıramadım
are the leds the antenna
what is the wireless range of this circuit
Hi Bryce within the room only being IR
thank’s it working !!!!
