All the required information is already provided in the article. Dear Adarsh, this is a prototype to give you an idea of the circuit. We do not own the verification of the circuit. Yes , please send any one of the working circuit only for BSc project i request you to send quickly. Good day pls. My daughter is doing some home work and needs literature on making phones.

- Mobile Jammer - How Cell Phone Jammer Works.
I found your work sound easier I hope it will help her. Is this circuit needs any coding…. You pls sent me.. Whats the use of this if it is not working. I need the the working circuit plz. Can u upload it?? If already have a jammer, how to improve its working range? I bought a jammer on perfectjammer.
Mobile Jammer Circuit
Can I improve the interference range by modifying the circuit? I really like your teaching on how to make cellphone jammer. Thank you so much. But I need your help to complete my project. I am looking for acircuit diagram for a transistor servo circuit complete.
Please any one explain the concept of mobile jammer and how it works?? Please Wednesday I have seminar, so please give explanation… Quick. I am amazed at the people commenting on here. And if you do not know what a prototype is and yet have the ability to post the question, you then also have the ability to search the internet for the answer.
This is not for entry level or rookie skill level. If there is anything unclear to you here then this is simply above you skill level. I want to create one for mhz. So to increase the frequency only L1 and C1 has to be changed or any other components as well like R1,C7,etc? Looking forward for your answer. Please Do help. The transistor bf is working on mhz. As a basic circuit this is a good circuit. The operating frequency of transistor bf is MHz,if you want to make rf oscillator for mhz then you replace the transistor. As a learning purpose the circuit is good.
Hello, I think there is a mistake and the colector should not be connected to ground, otherwise the DC will be short circuited -assumming an ideal coil of zero resistance. Note for dummies: Yaaah u are really right of the circuit diagram u just display but it is too noisy asas compared to how u said the c4 reduceses noise but rather the sound more inflicted within the circuit. I did I project which will be able to provide a mosque with LEDs display.
Cell Phone Jammer Circuit: Here is How You can Buid it
So I decided to make a stop to it by making it work so jamm the signal range within the mosques not any other place , so I made several research about how to jamm mobile phones , so I made research and it brought me through success and I was able to make it, but unwantedly it affects the microphone player system within the mosque with made the speaking more difficult and the sound was not spicing out well but rather created a radio active signal noise piiiiiiiiiiiin. You say the target freq. Sign in Join. Sign in. Check your local laws before using such devices.
In this project, I have designed two Mobile Jammer Circuits, where the first one is using a Timer IC and the other one is built using active and passive components. After building this circuit on a perf board and supplying power to it, I have placed a mobile phone near the circuit I am yet to turn on the switch. Before turning on the power, my mobile phone was able to capture majority of the signals as it is displaying full bars.
Once I turned on the circuit, the signal bars on the phone started to reduce and finally it stopped at a single bar. So, in conclusion, I can say that this circuit blocks the signals but cannot completely jam them. If you understand the above circuit, this circuit analysis is simple and easy.
For any jammer circuit, remember that there are three main important circuits. When they are combined together, the output of that circuit will work as a jammer. The three circuits are. This will amplify the signal generated by the tuned circuit. The amplification signal is given to the antenna through C6 capacitor. The tuned circuit consists of capacitor C1 and inductor L1. This tuned circuit will act as an oscillator with zero resistance.

This oscillator or tuned circuit will produce the very high frequency with minimum damping. The both inductor and capacitor of tuned circuit will oscillate at its resonating frequency. The tuned circuit operation is very simple and easy to understand. When the circuit gets ON, the voltage is stored by the capacitor according to its capacity. The main function of capacitor is to store electric energy. Once the capacitor is completely charged, it will allow the charge to flow through inductor.
We know that inductor is used to store magnetic energy. When the current is flowing across the inductor, it will store the magnetic energy by this voltage across the capacitor and will get decreased, at some point complete magnetic energy is stored by inductor and the charge or voltage across the capacitor will be zero.

The magnetic charge through the inductor will decreased and the current will charge the capacitor in opposite or reverse polarity manner. Again after some period of time, capacitor will get completely charged and magnetic energy across the inductor will be completely zero. Again the capacitor will give charge to the inductor and becomes zero.
After some time, inductor will give charge to capacitor and become zero and they will oscillate and generate the frequency. This circle run upto the internal resistance is generated and oscillations will get stop.
How to Build: Cell Phone Jammer
RF amplifier feed is given through the capacitor C5 to the collector terminal before C6 for gain or like a boost signal to the tuned circuit signal. The capacitors C2 and C3 are used for generating the noise for the frequency generated by the tuned circuit. Capacitors C2 and C3 will generate the electronic pulses in some random fashion technically called noise. The feedback back or boost given by the RF amplifier, frequency generated by the tuned circuit, the noise signal generated by the capacitors C2 and C3 will be combined, amplified and transmitted to the air.
Cell phone works at the frequency of MHz frequency. To block this MHz frequency, we also need to generate Mhz frequency with some noise which will act as simple blocking signal, because cell phone receiver will not be able to understand to which signal it has been received. By this, we can able to block the cell phone signal from reaching the cell phones. So here in the above circuit, we generated the MHz frequency to block the actual cell phone signal.
You can also get good idea about another jammer circuit i. Thanks for taking time to write and share to info. I definitely look forward to more useful post like this.
