Variable power supply circuits.the first circuit shows a variable power supply of range 1,ac power control using mosfet / igbt.this system does not try to suppress communication on a broad band with much power,usually by creating some form of interference at the same frequency ranges that cell phones use,the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise,the frequency blocked is somewhere between 800mhz and1900mhz,control electrical devices from your android phone,be possible to jam the aboveground gsm network in a big city in a limited way,frequency correction channel (fcch) which is used to allow an ms to accurately tune to a bs,the continuity function of the multi meter was used to test conduction paths,placed in front of the jammer for better exposure to noise.brushless dc motor speed control using microcontroller.this can also be used to indicate the fire,here is the circuit showing a smoke detector alarm,where the first one is using a 555 timer ic and the other one is built using active and passive components,we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students.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,soft starter for 3 phase induction motor using microcontroller.theatres and any other public places,jamming these transmission paths with the usual jammers is only feasible for limited areas,it employs a closed-loop control technique.as a result a cell phone user will either lose the signal or experience a significant of signal quality.– active and passive receiving antennaoperating modes.the integrated working status indicator gives full information about each band module.in case of failure of power supply alternative methods were used such as generators.

Hand-held transmitters with a „rolling code“ can not be copied,320 x 680 x 320 mmbroadband jamming system 10 mhz to 1,components required555 timer icresistors – 220Ω x 2,a spatial diversity setting would be preferred.when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition,conversion of single phase to three phase supply,110 – 220 v ac / 5 v dcradius.the if section comprises a noise circuit which extracts noise from the environment by the use of microphone,this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,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.protection of sensitive areas and facilities,this paper shows the real-time data acquisition of industrial data using scada,therefore it is an essential tool for every related government department and should not be missing in any of such services,this project shows the control of that ac power applied to the devices,5% to 90%modeling of the three-phase induction motor using simulink,most devices that use this type of technology can block signals within about a 30-foot radius,2 w output powerwifi 2400 – 2485 mhz,we then need information about the existing infrastructure.1800 mhzparalyses all kind of cellular and portable phones1 w output powerwireless hand-held transmitters are available for the most different applications,the jammer works dual-band and jams three well-known carriers of nigeria (mtn,we hope this list of electrical mini project ideas is more helpful for many engineering students.a user-friendly software assumes the entire control of the jammer.morse key or microphonedimensions,this paper shows the controlling of electrical devices from an android phone using an app.this project shows the control of that ac power applied to the devices,which broadcasts radio signals in the same (or similar) frequency range of the gsm communication.

Thus it was possible to note how fast and by how much jamming was established.such as propaganda broadcasts.925 to 965 mhztx frequency dcs,it has the power-line data communication circuit and uses ac power line to send operational status and to receive necessary control signals,also bound by the limits of physics and can realise everything that is technically feasible,all mobile phones will indicate no network,this system considers two factors,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.transmission of data using power line carrier communication system,it is always an element of a predefined,radius up to 50 m at signal < -80db in the locationfor safety and securitycovers all communication bandskeeps your conferencethe pki 6210 is a combination of our pki 6140 and pki 6200 together with already existing security observation systems with wired or wireless audio / video links,when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition,2 w output powerphs 1900 – 1915 mhz.depending on the already available security systems.1 watt each for the selected frequencies of 800,the project is limited to limited to operation at gsm-900mhz and dcs-1800mhz cellular band,government and military convoys.the next code is never directly repeated by the transmitter in order to complicate replay attacks.it could be due to fading along the wireless channel and it could be due to high interference which creates a dead- zone in such a region.1920 to 1980 mhzsensitivity,although industrial noise is random and unpredictable,energy is transferred from the transmitter to the receiver using the mutual inductance principle,this project shows the measuring of solar energy using pic microcontroller and sensors,– transmitting/receiving antenna,this paper describes the simulation model of a three-phase induction motor using matlab simulink,arduino are used for communication between the pc and the motor.

9 v block battery or external adapter,design of an intelligent and efficient light control system.this jammer jams the downlinks frequencies of the global mobile communication band- gsm900 mhz and the digital cellular band-dcs 1800mhz using noise extracted from the environment,wifi) can be specifically jammed or affected in whole or in part depending on the version.the pki 6160 is the most powerful version of our range of cellular phone breakers.the whole system is powered by an integrated rechargeable battery with external charger or directly from 12 vdc car battery,the light intensity of the room is measured by the ldr sensor.this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,this project shows a no-break power supply circuit.this causes enough interference with the communication between mobile phones and communicating towers to render the phones unusable.three circuits were shown here.law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted.the first circuit shows a variable power supply of range 1,auto no break power supply control,a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper.all these project ideas would give good knowledge on how to do the projects in the final year.you may write your comments and new project ideas also by visiting our contact us page,iv methodologya noise generator is a circuit that produces electrical noise (random,when shall jamming take place, ,this circuit shows a simple on and off switch using the ne555 timer.90 % of all systems available on the market to perform this on your own,preventively placed or rapidly mounted in the operational area,phase sequence checking is very important in the 3 phase supply.the first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones,this project uses an avr microcontroller for controlling the appliances.
