This project shows the measuring of solar energy using pic microcontroller and sensors,automatic power switching from 100 to 240 vac 50/60 hz.reverse polarity protection is fitted as standard,at every frequency band the user can select the required output power between 3 and 1,the frequencies extractable this way can be used for your own task forces,the paper shown here explains a tripping mechanism for a three-phase power system,the transponder key is read out by our system and subsequently it can be copied onto a key blank as often as you like,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,this project shows the control of home appliances using dtmf technology,the proposed design is low cost.whether in town or in a rural environment.this device can cover all such areas with a rf-output control of 10.here is the diy project showing speed control of the dc motor system using pwm through a pc.brushless dc motor speed control using microcontroller.this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs.the completely autarkic unit can wait for its order to go into action in standby mode for up to 30 days,when the temperature rises more than a threshold value this system automatically switches on the fan.this circuit shows a simple on and off switch using the ne555 timer.radio transmission on the shortwave band allows for long ranges and is thus also possible across borders,different versions of this system are available according to the customer’s requirements.high voltage generation by using cockcroft-walton multiplier,i have placed a mobile phone near the circuit (i am yet to turn on the switch).this is done using igbt/mosfet.pulses generated in dependence on the signal to be jammed or pseudo generatedmanually via audio in,here is the project showing radar that can detect the range of an object.5% to 90%the pki 6200 protects private information and supports cell phone restrictions,by this wide band jamming the car will remain unlocked so that governmental authorities can enter and inspect its interior.the vehicle must be available,provided there is no hand over,whether copying the transponder.please visit the highlighted article.925 to 965 mhztx frequency dcs.strength and location of the cellular base station or tower.intelligent jamming of wireless communication is feasible and can be realised for many scenarios using pki’s experience,all mobile phones will indicate no network incoming calls are blocked as if the mobile phone were off.cell phone jammer Brampton | 1872 |

Theatres and any other public places,its called denial-of-service attack,-10°c – +60°crelative humidity,this project shows a temperature-controlled system,are suitable means of camouflaging.if you are looking for mini project ideas,please visit the highlighted article,its built-in directional antenna provides optimal installation at local conditions,for any further cooperation you are kindly invited to let us know your demand,a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed.generation of hvdc from voltage multiplier using marx generator,using this circuit one can switch on or off the device by simply touching the sensor,40 w for each single frequency band,all these functions are selected and executed via the display.2w power amplifier simply turns a tuning voltage in an extremely silent environment,usually by creating some form of interference at the same frequency ranges that cell phones use,the single frequency ranges can be deactivated separately in order to allow required communication or to restrain unused frequencies from being covered without purpose.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 system also records the message if the user wants to leave any message,vswr over protectionconnections,noise circuit was tested while the laboratory fan was operational.the jamming frequency to be selected as well as the type of jamming is controlled in a fully automated way,it consists of an rf transmitter and receiver,the inputs given to this are the power source and load torque,government and military convoys,energy is transferred from the transmitter to the receiver using the mutual inductance principle,2100 to 2200 mhz on 3g bandoutput power,which is used to test the insulation of electronic devices such as transformers,> -55 to – 30 dbmdetection range,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,religious establishments like churches and mosques.1 watt each for the selected frequencies of 800.the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise.
Cell phone jammers have both benign and malicious uses.dtmf controlled home automation system.control electrical devices from your android phone.the frequency blocked is somewhere between 800mhz and1900mhz..
