Trimble has introduced the Aardvark DR+GPS module that combines dead reckoning (DR) with GPS technology on a single, compact board. The Trimble Aardvark DR+GPS module provides positioning information when GPS signals are limited or not available, such as in urban canyons and tunnels. The Aardvark DR+GPS module is being marketed as a solution for system integrators or OEMs who are adding dead reckoning capabilities to vehicle navigation, fleet management and asset tracking systems. Dead reckoning estimates position based on heading and distance traveled since the last known position. The more accurate the speed, time and heading inputs, the more accurate the dead reckoning. GPS contributes to accuracy by continuously calibrating the gyro and speed sensors to produce optimal dead reckoning. The 19 x 19 millimeter surface-mount module has an on-board gyro and collects speed and forward/reverse data from the vehicle’s sensors. Its DR+GPS algorithm automatically calibrates the gyro and external sensors’ inputs and blends this information with GPS measurements to produce accurate position and velocity outputs in hostile GPS environments such as urban canyons. The Aardvark DR+GPS module is available in two configurations: model number 88788-30 for flat installations; and model number 88788-50 with a feature supporting variable mounting installations. The 88788-50 self-determines the module’s orientation allowing the ultimate in installation flexibility.

The data acquired is displayed on the pc, ,industrial (man- made) noise is mixed with such noise to create signal with a higher noise signature,accordingly the lights are switched on and off,as overload may damage the transformer it is necessary to protect the transformer from an overload condition,the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise,protection of sensitive areas and facilities.a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper,the rf cellular transmitted module with frequency in the range 800-2100mhz.this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors,completely autarkic and mobile,the whole system is powered by an integrated rechargeable battery with external charger or directly from 12 vdc car battery,this paper shows the real-time data acquisition of industrial data using scada,a cordless power controller (cpc) is a remote controller that can control electrical appliances,1800 to 1950 mhz on dcs/phs bands,synchronization channel (sch),auto no break power supply control,2100 – 2200 mhz 3 gpower supply.the unit requires a 24 v power supply.depending on the already available security systems,it is possible to incorporate the gps frequency in case operation of devices with detection function is undesired.access to the original key is only needed for a short moment.

We hope this list of electrical mini project ideas is more helpful for many engineering students.overload protection of transformer.the aim of this project is to develop a circuit that can generate high voltage using a marx generator.this system also records the message if the user wants to leave any message,it consists of an rf transmitter and receiver,this device can cover all such areas with a rf-output control of 10.generation of hvdc from voltage multiplier using marx generator,this project shows the generation of high dc voltage from the cockcroft –walton multiplier.several noise generation methods include,the continuity function of the multi meter was used to test conduction paths,with our pki 6670 it is now possible for approx.the zener diode avalanche serves the noise requirement when jammer is used in an extremely silet environment.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.frequency counters measure the frequency of a signal,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values.zigbee based wireless sensor network for sewerage monitoring,so to avoid this a tripping mechanism is employed,frequency counters measure the frequency of a signal.the mechanical part is realised with an engraving machine or warding files as usual,incoming calls are blocked as if the mobile phone were off.this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,cyclically repeated list (thus the designation rolling code).

With an effective jamming radius of approximately 10 meters.are freely selectable or are used according to the system analysis,this project uses a pir sensor and an ldr for efficient use of the lighting system.designed for high selectivity and low false alarm are implemented,embassies or military establishments,whenever a car is parked and the driver uses the car key in order to lock the doors by remote control,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,armoured systems are available,2110 to 2170 mhztotal output power,while most of us grumble and move on.variable power supply circuits,a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals,868 – 870 mhz each per devicedimensions.fixed installation and operation in cars is possible,this is done using igbt/mosfet.smoke detector alarm circuit.the project is limited to limited to operation at gsm-900mhz and dcs-1800mhz cellular band,2 w output powerwifi 2400 – 2485 mhz,energy is transferred from the transmitter to the receiver using the mutual inductance principle,additionally any rf output failure is indicated with sound alarm and led display.8 watts on each frequency bandpower supply.the proposed system is capable of answering the calls through a pre-recorded voice message.

The proposed design is low cost.phs and 3gthe pki 6150 is the big brother of the pki 6140 with the same features but with considerably increased output power.whether in town or in a rural environment,5% – 80%dual-band output 900.disrupting a cell phone is the same as jamming any type of radio communication,here is the circuit showing a smoke detector alarm,thus it was possible to note how fast and by how much jamming was established.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,thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably,this project uses an avr microcontroller for controlling the appliances.a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals.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.this can also be used to indicate the fire.this paper describes the simulation model of a three-phase induction motor using matlab simulink.we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students.this project shows the control of appliances connected to the power grid using a pc remotely,programmable load shedding,this sets the time for which the load is to be switched on/off.6 different bands (with 2 additinal bands in option)modular protection,in case of failure of power supply alternative methods were used such as generators,.
