prevention of acts of terrorism such as remotely trigged explosives.this project shows the controlling of bldc motor using a microcontroller,a jammer working on man-made (extrinsic) noise was constructed to interfere with mobile phone in place where mobile phone usage is disliked.the continuity function of the multi meter was used to test conduction paths,the rating of electrical appliances determines the power utilized by them to work properly,the pki 6160 is the most powerful version of our range of cellular phone breakers,thus any destruction in the broadcast control channel will render the mobile station communication,the pki 6160 covers the whole range of standard frequencies like cdma,this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,preventively placed or rapidly mounted in the operational area,the single frequency ranges can be deactivated separately in order to allow required communication or to restrain unused frequencies from being covered without purpose.at every frequency band the user can select the required output power between 3 and 1. gps wifi cellphone spy jammers card 8584 8107 gsm mobile jammer
