Cell Phone Jammer Circuit
A DIY GSM jammer schematic diagram designed for use with GSM1900, operating within the frequency range of 1930 MHz to 1990 MHz.
The GSM jammer circuit is intended to disrupt communication between mobile phones and base stations within the specified frequency...
Carrier-Current Receiver For Data Transmission
This receiver consists of an input network, amplifier IC7, FSK PLL detector IC8, and output amplifier/interface circuits Q2, Q3, IC3A, and IC3B, which include a 1488 Quad RS232 line driver for the carrier-current signal. The tuned amplifier IC7 amplifies this...
Wireless Communication Hobby Projects
Another method of testing the received signal strength on a Symphony-based wireless network is with a homebrew signal meter. The National LMX2240 Intermediate Frequency Receiver has a pin called "RSSI Out." RSSI stands for Relative Signal Strength Indicator and provides...

New uTracker on GE865 with a compact design. This updated version of the tracker features the SIM300DZ and EB-230/LEA-5S modules. It includes an OBD-II (ISO) sensor, an accelerometer, and an RFID reader. Additionally, a TR24 2.4GHz module is incorporated, excluding...
GSM localizer without GPS Schematic
The circuit for the localizer is based on a quad-band GSM/GPRS module interfaced with a microcontroller. After initializing the I/Os and UARTs, the microcontroller enters a loop waiting for events, such as the arrival of an SMS or the pressing...
GSM Automatic Meter Reading
GSM based Automatic meter reading, or AMR, is the technology of automatically collecting data from energy meter and transferring that data to a central database for billing and/or analyzing. The Transmitter is connected to the meter and it counts the...
gsm gps based vehicle theft control
This project focuses on the design and development of a theft control system for automobiles, aimed at preventing and controlling vehicle theft. The system utilizes an embedded design based on GSM and GPS technology. It is installed within the vehicle...
GSM Remote Control Gate Control Schematic
Power is supplied by continuous voltage, which is not always stabilized, applied to PWR + and - at a value between 5 and 32V. This voltage is filtered at the bottom by a diode (D1) that protects against polarity inversion,...
DIY mobile phone jammer Schematic Diagram
A DIY GSM jammer schematic diagram designed to disrupt cellular mobile phone signals operating within the GSM1900 frequency range of 1930 MHz to 1990 MHz. The GSM1900 standard is utilized in the USA, Canada, and most countries in South America....
