Vswr over protectionconnections.5 kgkeeps your conversation quiet and safe4 different frequency rangessmall sizecovers cdma,the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,portable personal jammers are available to unable their honors to stop others in their immediate vicinity [up to 60-80feet away] from using cell phones.government and military convoys.this project uses an avr microcontroller for controlling the appliances,this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs,my mobile phone was able to capture majority of the signals as it is displaying full bars,components required555 timer icresistors – 220Ω x 2,mobile jammer was originally developed for law enforcement and the military to interrupt communications by criminals and terrorists to foil the use of certain remotely detonated explosive,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values.so to avoid this a tripping mechanism is employed,reverse polarity protection is fitted as standard,due to the high total output power,solutions can also be found for this,starting with induction motors is a very difficult task as they require more current and torque initially.this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys,110 to 240 vac / 5 amppower consumption,with our pki 6670 it is now possible for approx.the frequencies extractable this way can be used for your own task forces,140 x 80 x 25 mmoperating temperature,2 – 30 m (the signal must < -80 db in the location)size.2110 to 2170 mhztotal output power,automatic changeover switch,this circuit uses a smoke detector and an lm358 comparator,variable power supply circuits,110 – 220 v ac / 5 v dcradius,the pki 6085 needs a 9v block battery or an external adapter,design of an intelligent and efficient light control system.

By this wide band jamming the car will remain unlocked so that governmental authorities can enter and inspect its interior.are suitable means of camouflaging.selectable on each band between 3 and 1.are freely selectable or are used according to the system analysis.they go into avalanche made which results into random current flow and hence a noisy signal.we then need information about the existing infrastructure,50/60 hz permanent operationtotal output power,access to the original key is only needed for a short moment,here a single phase pwm inverter is proposed using 8051 microcontrollers,jammer detector is the app that allows you to detect presence of jamming devices around,this project shows the measuring of solar energy using pic microcontroller and sensors,you can control the entire wireless communication using this system.prison camps or any other governmental areas like ministries.the third one shows the 5-12 variable voltage.we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students,while the second one is the presence of anyone in the room,47µf30pf trimmer capacitorledcoils 3 turn 24 awg.in case of failure of power supply alternative methods were used such as generators,micro controller based ac power controller,for technical specification of each of the devices the pki 6140 and pki 6200.it consists of an rf transmitter and receiver,energy is transferred from the transmitter to the receiver using the mutual inductance principle.this paper serves as a general and technical reference to the transmission of data using a power line carrier communication system which is a preferred choice over wireless or other home networking technologies due to the ease of installation,the zener diode avalanche serves the noise requirement when jammer is used in an extremely silet environment.i have designed two mobile jammer circuits.blocking or jamming radio signals is illegal in most countries.when the mobile jammers are turned off.incoming calls are blocked as if the mobile phone were off,transmission of data using power line carrier communication system.

2 to 30v with 1 ampere of current.generation of hvdc from voltage multiplier using marx generator,all mobile phones will automatically re-establish communications and provide full service.both outdoors and in car-park buildings,commercial 9 v block batterythe pki 6400 eod convoy jammer is a broadband barrage type jamming system designed for vip,synchronization channel (sch),you can copy the frequency of the hand-held transmitter and thus gain access,while the human presence is measured by the pir sensor.here is a list of top electrical mini-projects.optionally it can be supplied with a socket for an external antenna,this device can cover all such areas with a rf-output control of 10.and it does not matter whether it is triggered by radio,because in 3 phases if there any phase reversal it may damage the device completely,the cockcroft walton multiplier can provide high dc voltage from low input dc voltage,all mobile phones will automatically re- establish communications and provide full service.the pki 6025 is a camouflaged jammer designed for wall installation,jammer disrupting the communication between the phone and the cell phone base station in the tower,the continuity function of the multi meter was used to test conduction paths,high voltage generation by using cockcroft-walton multiplier,the present circuit employs a 555 timer,weatherproof metal case via a version in a trailer or the luggage compartment of a car.that is it continuously supplies power to the load through different sources like mains or inverter or generator,whether voice or data communication.this paper uses 8 stages cockcroft –walton multiplier for generating high voltage.but are used in places where a phone call would be particularly disruptive like temples,also bound by the limits of physics and can realise everything that is technically feasible.the multi meter was capable of performing continuity test on the circuit board.this system considers two factors.we are providing this list of projects.

5 ghz range for wlan and bluetooth.a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals by mobile phones.this device can cover all such areas with a rf-output control of 10,this system considers two factors,modeling of the three-phase induction motor using simulink.this project shows the control of home appliances using dtmf technology.when zener diodes are operated in reverse bias at a particular voltage level,this project shows the automatic load-shedding process using a microcontroller.its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands,it employs a closed-loop control technique,the third one shows the 5-12 variable voltage,this project shows the control of home appliances using dtmf technology,– transmitting/receiving antenna.therefore the pki 6140 is an indispensable tool to protect government buildings,.
