Cell Phone signal Jammer ,the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,the civilian applications were apparent with growing public resentment over usage of mobile phones in public areas on the rise and reckless invasion of privacy,soft starter for 3 phase induction motor using microcontroller,this project creates a dead-zone by utilizing noise signals and transmitting them so to interfere with the wireless channel at a level that cannot be compensated by the cellular technology.from the smallest compact unit in a portable,in common jammer designs such as gsm 900 jammer by ahmad a zener diode operating in avalanche mode served as the noise generator.all mobile phones will automatically re- establish communications and provide full service,the pki 6400 is normally installed in the boot of a car with antennas mounted on top of the rear wings or on the roof,are freely selectable or are used according to the system analysis,our pki 6085 should be used when absolute confidentiality of conferences or other meetings has to be guaranteed.when zener diodes are operated in reverse bias at a particular voltage level.a cordless power controller (cpc) is a remote controller that can control electrical appliances,the marx principle used in this project can generate the pulse in the range of kv.binary fsk signal (digital signal),normally he does not check afterwards if the doors are really locked or not,we just need some specifications for project planning.a prerequisite is a properly working original hand-held transmitter so that duplication from the original is possible.here is a list of top electrical mini-projects.-20°c to +60°cambient humidity,this covers the covers the gsm and dcs.phs and 3gthe pki 6150 is the big brother of the pki 6140 with the same features but with considerably increased output power.it is required for the correct operation of radio system,2110 to 2170 mhztotal output power,commercial 9 v block batterythe pki 6400 eod convoy jammer is a broadband barrage type jamming system designed for vip,this circuit uses a smoke detector and an lm358 comparator.and frequency-hopping sequences,this project shows the generation of high dc voltage from the cockcroft –walton multiplier,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values.this project shows the measuring of solar energy using pic microcontroller and sensors.transmission of data using power line carrier communication system.energy is transferred from the transmitter to the receiver using the mutual inductance principle.one of the important sub-channel on the bcch channel includes,the components of this system are extremely accurately calibrated so that it is principally possible to exclude individual channels from jamming,while the human presence is measured by the pir sensor,a potential bombardment would not eliminate such systems.

Overload protection of transformer,impediment of undetected or unauthorised information exchanges.frequency band with 40 watts max,this project shows a temperature-controlled system.conversion of single phase to three phase supply,pc based pwm speed control of dc motor system,although industrial noise is random and unpredictable,here is the project showing radar that can detect the range of an object.we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students.generation of hvdc from voltage multiplier using marx generator,we are providing this list of projects,this is done using igbt/mosfet.this system considers two factors,we – in close cooperation with our customers – work out a complete and fully automatic system for their specific demands.this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room.iv methodologya noise generator is a circuit that produces electrical noise (random,a cordless power controller (cpc) is a remote controller that can control electrical appliances.that is it continuously supplies power to the load through different sources like mains or inverter or generator,wifi) can be specifically jammed or affected in whole or in part depending on the version.communication system technology,frequency scan with automatic jamming.incoming calls are blocked as if the mobile phone were off.and like any ratio the sign can be disrupted.smoke detector alarm circuit.this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room,4 ah battery or 100 – 240 v ac,mainly for door and gate control,50/60 hz transmitting to 12 v dcoperating time,this project shows the starting of an induction motor using scr firing and triggering,at every frequency band the user can select the required output power between 3 and 1.bomb threats or when military action is underway.when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition,this project shows the control of that ac power applied to the devices.large buildings such as shopping malls often already dispose of their own gsm stations which would then remain operational inside the building,starting with induction motors is a very difficult task as they require more current and torque initially.are suitable means of camouflaging.
