0 TV remote jammer

The tv remote control transmits signal to the tv in pulses at around 37.5kHz frequency. Every button in your remote when pressed  has an equivalent pulses  or signal codes.This remote jammer circuit will transmit pulses of the same frequency as the remote to confuse your tv set from decoding the transmitted signal.

circuit schematic

Part list:
2-1k resistor
2-10nF
1-5k pot
1-555
1-100
1-2n2222
1-IRled
1-1.2k
1-9V battery

Operation:
The heart of the circuit is the 555 timer IC operated in astable mode.The circuit will output  series of pulses at a frequency of 18kHz up to 48kHz by simply adjusting the 5K potentiometer. What you will do is adjust the potentiometer until it jives to the frequeny of your TV remote or until the signal is ignored by the TV set.
See 555 calculator if you are planning to use other values of capacitor and resistor in your circuit.

Note: The circuit is primarily for educational purpose only, other than this  use it at your own risk.
