  1. Remote Jamming Device

  2. Remote Jamming Device Introduction • The project develops a remote jamming device which can jam the TV remote rays. It develops IR rays of 38 KHz usually emitted by a standard TV remote. The rays developed are powerful enough to overshadow the IR receiver in TV. This system is built by using a 555 Timer in the astable mode which is made to produce the higher power pulses in the range of 38 KHZ emitted by an IR diode. These rays while aimed at TV receiver disables the IR sensor built in the TV. Thus, while any number is pressed on the TV remote, the IR rays sent will not have any effect on TV. http://www.edgefxkits.com/

  4. Remote Jamming Device Hardware Components • IR LED • Timer IC • Transistors • Preset • Switch • Diodes • Capacitors • Resistors http://www.edgefxkits.com/

  5. Remote Jamming Device Light Emitting Diode • LED is a two lead semiconductor light source. • These are typically small (less than 1 mm2 ) and integrated optical components may be used to shape the radiation pattern. http://www.edgefxkits.com/

  6. Remote Jamming Device Switch • Switch is an electrical component that can "break" or "make" an electrical circuit. • The mechanism of a switch removes or restores the conducting path in a circuit when it is operated. http://www.edgefxkits.com/

  7. Remote Jamming Device Operating Principle Of 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. http://www.edgefxkits.com/
