TV Remote Jammer!: I’ve had a few scuffles in my house over the TV remote so I decided to do something about it. I built a circuit that will block my TV and any. TV Remote Jammer: As,we all know that the TV remote is the cause of fights among us and our siblings(specially the younger ones).So, was my case. I decided. TV REMOTE CONTROL JAMMER Circuit. This circuit confuses the infra-red receiver in a TV. It produces a constant signal that interferes with the signal from a.

Seetharaman, Has any person tried this circuit before? Hi Bryce within the room only being IR. Yes it can jam any IR remote control. The circuit can be assembled on a Vero board.

Here is the circuit diagram of simple but highly effective TV remote jammer circuit. Remote Circuits Television Related. Please see the note. Get Our Weekly Newsletter! The communication established here is of frequency Use a 9V PP3 battery for jammsr the circuit. I need it urgent pleaseā€¦. You may also like: A flood of IR uammer in the same frequency can easily confuse the TV receiver and this is the operating principle jammdr our jammer.

The pulses when passed through decoders or filters at the receiving end In this case, a TV we get a complete ONE logic as shown in second graph of figure. Because of these different intervals the receiver gets the correct information regarding the user requirement and acts accordingly. How are you sure that it is producing IR signal? Does C1 and C2 are electrolytes or ceramics? I make it but it is not working ,it produce IR signal but not jammed tv signal. To keep the LED in one piece you might have to switch out a few resistors for different values.


Because of the continuous pulses by the TV remote signal jammer circuit the intervals of the remote are overlapped and the receiver reads ONE always. Jammeg basically this circuit is a IR jammer circuit.

Any body know means pls tell me. The circuit is nothing but an astable multivibrator based on NE IC. Yes you can use this circuit to stop the working of your TV remote and nobody would have a clue about why that stopped working. Run the circuit and look the LED using camera. Because this is too fast for a camera to pick, It picks up continuous turned on pulse.

TV remote jammer – Electronic Circuits and Diagrams-Electronic Projects and Design

Gemote intervals differ with every button pressed. Hi Rex When this device is transmitting IR signal, the TV will not respond to commands from the original TV remote control, provided the frequencies of both are matched as explained in the text.

Please give a substitute transistor in the place of SK Mount the IC on a holder. Could you please provide me? Leave a Reply Cancel reply Your email address will not be published. How do I turn it on and off? Simply speaking we are going to induce a lot of noise into the IR signal, for the receiver to completely read error all the time. I need a mobile gammer circuit for a certain area range to block the incomeing call.

Previous post Next post. Not only TV remotes, but any IR remotes operating in the 38KHz frequency region can be also jammed by using this circuit. Also check this IR remote control tester circuit. Now how we are going to stop the communication is the tricky part! How to adjust R4 to get matching frequency. What are the alternatives to the SK transistor? Because of this, there will be no communication between the transmitter and receiver.


These IR pulses by remote control can not be detected by human eye. The TV consists of an IR receiver which receives these blinking pulses and decodes them for appropriate response.

Can this circuit jam TV receiver sets? Because of these continuous pulses the receiver cannot pick up the intervals send by the TV remote control. Most of the TV remotes have 38KHz operating frequency. Would you like to surprise your family members or friends by making this fun circuit namely ” TV remote jammer circuit “? Your email address will not be published.

Seetharaman, have you use this circuit to jam any TV Receiver Sets before?

Please reply me because i want to build this circuit. So every time a button is pressed the remote sends out 38 KHz frequency IR pulses with regular intervals.

We are going to design a circuit which sends the pulses continuously. What hapens to the circuit when i use ohm instead of ohm as R5. The potentiometer in the circuit must be adjusted to get the correct frequency. TV remote jammer john August 27, 42 Comments.

Hi Vamsi it is remtoe only the frequency adjustment requires little patience and trials.
