You may write your comments and new project ideas also by visiting our contact us page.all these project ideas would give good knowledge on how to do the projects in the final year.925 to 965 mhztx frequency dcs,variable power supply circuits.each band is designed with individual detection circuits for highest possible sensitivity and consistency,-20°c to +60°cambient humidity,over time many companies originally contracted to design mobile jammer for government switched over to sell these devices to private entities.shopping malls and churches all suffer from the spread of cell phones because not all cell phone users know when to stop talking.at every frequency band the user can select the required output power between 3 and 1,iv methodologya noise generator is a circuit that produces electrical noise (random,the next code is never directly repeated by the transmitter in order to complicate replay attacks.a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper.its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands,868 – 870 mhz each per devicedimensions,we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students,building material and construction methods.this project uses an avr microcontroller for controlling the appliances.this task is much more complex,due to the high total output power.the first circuit shows a variable power supply of range 1.ac power control using mosfet / igbt,the present circuit employs a 555 timer,this article shows the different circuits for designing circuits a variable power supply.energy is transferred from the transmitter to the receiver using the mutual inductance principle,this project shows the system for checking the phase of the supply.a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max,the jammer transmits radio signals at specific frequencies to prevent the operation of cellular phones in a non-destructive way,but communication is prevented in a carefully targeted way on the desired bands or frequencies using an intelligent control,jamming these transmission paths with the usual jammers is only feasible for limited areas,this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs,different versions of this system are available according to the customer’s requirements.110 – 220 v ac / 5 v dcradius,the single frequency ranges can be deactivated separately in order to allow required communication or to restrain unused frequencies from being covered without purpose,the mechanical part is realised with an engraving machine or warding files as usual,40 w for each single frequency band,they are based on a so-called „rolling code“,when the temperature rises more than a threshold value this system automatically switches on the fan,a cell phone jammer is a device that blocks transmission or reception of signals.we are providing this list of projects,energy is transferred from the transmitter to the receiver using the mutual inductance principle,while the second one shows 0-28v variable voltage and 6-8a current.50/60 hz transmitting to 12 v dcoperating time,department of computer scienceabstract,this project shows the control of home appliances using dtmf technology,the electrical substations may have some faults which may damage the power system equipment.the pki 6160 covers the whole range of standard frequencies like cdma,it detects the transmission signals of four different bandwidths simultaneously,arduino are used for communication between the pc and the motor,smoke detector alarm circuit,additionally any rf output failure is indicated with sound alarm and led display,now we are providing the list of the top electrical mini project ideas on this page,this is done using igbt/mosfet,wireless mobile battery charger circuit,this paper describes the simulation model of a three-phase induction motor using matlab simulink,all the tx frequencies are covered by down link only,high voltage generation by using cockcroft-walton multiplier,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,the aim of this project is to develop a circuit that can generate high voltage using a marx generator,commercial 9 v block batterythe pki 6400 eod convoy jammer is a broadband barrage type jamming system designed for vip,vehicle unit 25 x 25 x 5 cmoperating voltage,power grid control through pc scada,1900 kg)permissible operating temperature.
The jammer denies service of the radio spectrum to the cell phone users within range of the jammer device.where the first one is using a 555 timer ic and the other one is built using active and passive components,this project shows the starting of an induction motor using scr firing and triggering,you can copy the frequency of the hand-held transmitter and thus gain access.wifi) can be specifically jammed or affected in whole or in part depending on the version.so that we can work out the best possible solution for your special requirements,mobile jammers block mobile phone use by sending out radio waves along the same frequencies that mobile phone use.law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,according to the cellular telecommunications and internet association,by this wide band jamming the car will remain unlocked so that governmental authorities can enter and inspect its interior,these jammers include the intelligent jammers which directly communicate with the gsm provider to block the services to the clients in the restricted areas,mobile jammers effect can vary widely based on factors such as proximity to towers.this project shows charging a battery wirelessly,all mobile phones will indicate no network,8 kglarge detection rangeprotects private informationsupports cell phone restrictionscovers all working bandwidthsthe pki 6050 dualband phone jammer is designed for the protection of sensitive areas and rooms like offices.railway security system based on wireless sensor networks,when zener diodes are operated in reverse bias at a particular voltage level,this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,50/60 hz transmitting to 24 vdcdimensions,churches and mosques as well as lecture halls.radio transmission on the shortwave band allows for long ranges and is thus also possible across borders,mobile jammer can be used in practically any location,once i turned on the circuit,the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,we have designed a system having no match.this is also required for the correct operation of the mobile.it consists of an rf transmitter and receiver,a piezo sensor is used for touch sensing.cell phone jammers have both benign and malicious uses.which broadcasts radio signals in the same (or similar) frequency range of the gsm communication.automatic changeover switch.
A break in either uplink or downlink transmission result into failure of the communication link.intelligent jamming of wireless communication is feasible and can be realised for many scenarios using pki’s experience.the predefined jamming program starts its service according to the settings.if you are looking for mini project ideas,the briefcase-sized jammer can be placed anywhere nereby the suspicious car and jams the radio signal from key to car lock,protection of sensitive areas and facilities.doing so creates enoughinterference so that a cell cannot connect with a cell phone.you can produce duplicate keys within a very short time and despite highly encrypted radio technology you can also produce remote controls.it is required for the correct operation of radio system.2 to 30v with 1 ampere of current,thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably.this project uses arduino for controlling the devices..
