TV Remote Jammer Using 555 ICTV Remote Jammer Using 555 IC

The TV remote control transmits television signals as pulses of frequency around 37.5kHz. Each button on the remote control is pressed or equivalent has a pulse signal codes. This remote transmits pulses of the circuit block of the same frequency as the remote to your TV confuse decoding the transmitted signal.

The heart of the circuit is the 555 timer IC in astable circuit works mode.The output series of pulses at a frequency of 18 kHz to 48 kHz by simply adjusting the 5K potentiometer. What you do is adjust the potentiometer until frequeny jives to its distance from the TV or until the signal is ignored by television.

Most of people ask TV transmitters.So Today Im going to offer you an awfully useful circuit diagram.By using this circuit that you may ship your signals 75m to 100m.This circuit diagram is just not my own circuit one of my friends gave me this.I believe you guys can even ship your own circuit diagrams for us.Then we can submit them via our website online.Here They have used common transistor BC 108 If you're unable to seek out this transistor you wish to use equal transistors like Bc337 2n2222 Bc 546

 Note

# To make L1 wound 6 flips of #24 enameled wire on a 10mm air former for frequency 60 - eighty MHz For one hundred fifty - one hundred eighty MHz wound 4 flips and for one hundred eighty - 200MHz wound 2 turns.

# This circuit functions with 9V energy supply

# When you construct this circuit you have to build this on somewhat area.

# The energy of this circuit is eightymW

# use a pcb to build this circuit diagram.

# This is just for educational objective.We can endure any responsibility of this If you misused this.

# This circuit transmit simplest video alerts .If you need to ship sound indicators you need to use an audio transmitter
