Cell Phone Jamming Circuit Diagram, Schematic, and Report for Final Year Project

please i need the circuit diagram, schematic and report writing on cell phone jamming circuit. this is my final year project.

Limor Fried of adafruit has beat you to it: http://www.ladyada.net/make/wavebubble/

...and why don't you make them yourself? or at least "get inspired" from someone on the internet instead of asking someone else to do it for you.

It's not a project with a very high degree of difficulty.

I say you give it a try and come back here with actual questions about what you did in case you get stuck or don't understand something from what you researched yourself.

This is not legal in most jurisdictions.

Uche, if u want to build a jammer especially for an academic project,it has to be a useful one to your surrounding. First of all you need to gather essential info about the project. The info you need to provide and tackle during your project are things like; 1-What frequency or frequencies do you want to jamm, 2-What should be the power or range of your jamming signal, 3-What is the relevance of jamming the signal. The third point will be useful in your project write up, since you will be required to show the usefulness of you project. If you are going to build a GSM jammer then you will have to do some research work on GSM 900 and GSM 1800 frequency bands. Try and meet any mobile phone operator technicians for your country's mobile frequency bands. Note that you will have to work(study a little bit) on RF transmission because the above frequency bands are in MHz. The next thing will be the characteristics of your jammer; is it a constantly running jammer or a detect then block jammer. The second type is more complicated but less wave polluting than the first since it embeds a mobile bug which on detection activates the jammer proper. Since you seem to be new in the field, the free running type will be the best. The block of the system is the power supply, the IF-Intermediate Frequency section, and the RF-Radio frequency section. Start from somewhere with this piece of info and update us so we can know where you have difficulties and help, it's much more better than just giving you some schematics, and you hunting for components and design caculations.

Yea its the proper way to continue on a project. start from the basic knowledge, then understand your problem part by part because once you get knowledge about that thing you can design your own project that wont be a copy.

thank you MR khaba you are absolutly right i will begin by collecting all available information about the project then start to acheive it. and i will keep in touch with you to tell you what stops me and thank you once more .

thank you MR kumar. i will do it thank you again keep in touch.

Here is a gorgeous video http://www.youtube.com/watch?v=BBH9ZUv8yio ~~~LOL..

Hey, guys,
I am a university student from Portugal called ISEP and I have to do a project in my course of the last year. I think a jammer signal could be an interresting thing to do. I have some knowledge in electronics and programming skills nothing very crazy since I am in a course of 3 years, waiting to finish to start 2 more masters. So I saw this site you posted here "bubble wave" and it is something like what I would like to build, but since on the site there is no scematics wanted to know if it is possible with reserch to build it?
My english is very bad.
