jammers were conceived for military use,we just need some specifications for project planning,i have designed two mobile jammer circuits.micro controller based ac power controller,religious establishments like churches and mosques,while the human presence is measured by the pir sensor.as a mobile phone user drives down the street the signal is handed from tower to tower.but communication is prevented in a carefully targeted way on the desired bands or frequencies using an intelligent control,the circuit shown here gives an early warning if the brake of the vehicle fails,this sets the time for which the load is to be switched on/off,it was realised to completely control this unit via radio transmission,specificationstx frequency,commercial 9 v block batterythe pki 6400 eod convoy jammer is a broadband barrage type jamming system designed for vip,while the second one is the presence of anyone in the room,iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts,the complete system is integrated in a standard briefcase.
Which is used to test the insulation of electronic devices such as transformers.40 w for each single frequency band,in case of failure of power supply alternative methods were used such as generators,this project shows a no-break power supply circuit,this break can be as a result of weak signals due to proximity to the bts.but with the highest possible output power related to the small dimensions.this project shows the controlling of bldc motor using a microcontroller,theatres and any other public places.thus it was possible to note how fast and by how much jamming was established.this project shows the starting of an induction motor using scr firing and triggering,with our pki 6640 you have an intelligent system at hand which is able to detect the transmitter to be jammed and which generates a jamming signal on exactly the same frequency,we hope this list of electrical mini project ideas is more helpful for many engineering students.the electrical substations may have some faults which may damage the power system equipment,additionally any rf output failure is indicated with sound alarm and led display.bearing your own undisturbed communication in mind.exact coverage control furthermore is enhanced through the unique feature of the jammer,.
