Adopter
Designed a 220V AC to 5V DC adopter in PSPICE and then implemented it in real using veroboard and ICs
Parallel port programmer of Microcontroller
Designed and implemented a Parallel Port Programmer for Microcontroller 89S52 and verified its execution by interfacing its with touch keypad and 4 digit LED
Server to Client file transfer application
Coded a server to client file (up to 20MB) transfer application in C++ using WinSock API having client ignore and client blocking functions.
Communication of FM Transmitter and Receiver
Designed and Implemented a FM communication system, using XR2206 as modulator and CD4046 as demodulator of a simple voice signal fed by a microphone to receiver.
Final Year Project (FM and GSM jamming )
In frequency jammers/blockers the basic concept is very simple to transmit carrier signal and sweep it at the same frequencies at which communication is taking place. The jamming signal should be of greater power after which communication can’t take place. Design should be compatible enough to decrease the SNR of the covered area below the threshold limits of the communication system.
Project Part1 - The bandwidth of FM is from 88-108 MHz. Hence continuous variable sine signal from lower to high frequency interferes with the original communication signal and jams it.
Project Part2 - The uplink frequency range of GSM900 is 890 – 915 MHz and downlink range frequency is 935 – 960 MHz. Transmitting a signal at downlink frequency range will wipe out all the Control Signals from Base Station in the covered area and mobile will not be able to detect any network coverage.
Circuitry:
The main electronic components of a jammer are:
Voltage controlled oscillator– It is the heart of any transmission device. It produces the desired output frequency.
Tuning circuit– This circuit controls the output frequency of the VCO. Its frequency determines the sweeping time of output signal.
RF amplification–The output voltage of VCO is usually low so amplifier is used to amplify the signal so it’s powerful enough to over ride the communication signal.
Power Supply–This sections provides adequate voltage levels to different pins of the working ICs. It is implemented using standard batteries, voltages regulators and voltage dividers.
Antenna-Every transmitter has an antenna, it could be internal or external. Dipole or quater pole anetnnas can be used according to efficienty needs.
