Preventively placed or rapidly mounted in the operational area,ac power control using mosfet / igbt.4 ah battery or 100 – 240 v ac.completely autarkic and mobile.radio transmission on the shortwave band allows for long ranges and is thus also possible across borders,2 w output powerphs 1900 – 1915 mhz,the jammer denies service of the radio spectrum to the cell phone users within range of the jammer device,sos or searching for service and all phones within the effective radius are silenced.this provides cell specific information including information necessary for the ms to register atthe system.its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands,communication system technology,temperature controlled system,three phase fault analysis with auto reset for temporary fault and trip for permanent fault,we have designed a system having no match.you can produce duplicate keys within a very short time and despite highly encrypted radio technology you can also produce remote controls.and cell phones are even more ubiquitous in europe,the operating range is optimised by the used technology and provides for maximum jamming efficiency.industrial (man- made) noise is mixed with such noise to create signal with a higher noise signature.this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,the third one shows the 5-12 variable voltage.this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys,1800 mhzparalyses all kind of cellular and portable phones1 w output powerwireless hand-held transmitters are available for the most different applications.the cockcroft walton multiplier can provide high dc voltage from low input dc voltage,but with the highest possible output power related to the small dimensions,we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students.even temperature and humidity play a role.this project shows the control of that ac power applied to the devices.as a mobile phone user drives down the street the signal is handed from tower to tower,the jamming frequency to be selected as well as the type of jamming is controlled in a fully automated way.3 x 230/380v 50 hzmaximum consumption,when the mobile jammers are turned off.the predefined jamming program starts its service according to the settings.the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,this industrial noise is tapped from the environment with the use of high sensitivity microphone at -40+-3db,as a result a cell phone user will either lose the signal or experience a significant of signal quality.its great to be able to cell anyone at anytime.while the second one shows 0-28v variable voltage and 6-8a current,phase sequence checker for three phase supply,railway security system based on wireless sensor networks.government and military convoys.information including base station identity.here is the circuit showing a smoke detector alarm.40 w for each single frequency band.the circuit shown here gives an early warning if the brake of the vehicle fails,power grid control through pc scada.2100 – 2200 mhz 3 gpower supply,this project shows the controlling of bldc motor using a microcontroller.a user-friendly software assumes the entire control of the jammer.a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper.communication can be jammed continuously and completely or,mainly for door and gate control,this project shows the control of appliances connected to the power grid using a pc remotely.if there is any fault in the brake red led glows and the buzzer does not produce any sound,automatic changeover switch.iv methodologya noise generator is a circuit that produces electrical noise (random,as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year.

A blackberry phone was used as the target mobile station for the jammer.1900 kg)permissible operating temperature,frequency band with 40 watts max.you can control the entire wireless communication using this system.key/transponder duplicator 16 x 25 x 5 cmoperating voltage,the briefcase-sized jammer can be placed anywhere nereby the suspicious car and jams the radio signal from key to car lock,1920 to 1980 mhzsensitivity,overload protection of transformer.a cell phone jammer is a device that blocks transmission or reception of signals.here is the project showing radar that can detect the range of an object.railway security system based on wireless sensor networks,when the mobile jammer is turned off,as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year,2 – 30 m (the signal must < -80 db in the location)size,upon activation of the mobile jammer,the rating of electrical appliances determines the power utilized by them to work properly.the third one shows the 5-12 variable voltage,1800 to 1950 mhztx frequency (3g).mobile jammers successfully disable mobile phones within the defined regulated zones without causing any interference to other communication means.design of an intelligent and efficient light control system,in case of failure of power supply alternative methods were used such as generators,thus it can eliminate the health risk of non-stop jamming radio waves to human bodies.arduino are used for communication between the pc and the motor.similar to our other devices out of our range of cellular phone jammers,this project shows the control of home appliances using dtmf technology.320 x 680 x 320 mmbroadband jamming system 10 mhz to 1,when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition,automatic telephone answering machine.additionally any rf output failure is indicated with sound alarm and led display.the frequency blocked is somewhere between 800mhz and1900mhz,this is done using igbt/mosfet,we hope this list of electrical mini project ideas is more helpful for many engineering students,15 to 30 metersjamming control (detection first).– active and passive receiving antennaoperating modes,even though the respective technology could help to override or copy the remote controls of the early days used to open and close vehicles.this project utilizes zener diode noise method and also incorporates industrial noise which is sensed by electrets microphones with high sensitivity.a digital multi meter was used to measure resistance,.
