Mobile Scanner Circuit
A device designed to locate a mobile phone by emitting intermittent flashes and beeps, indicating the presence of an active mobile phone. This circuit activates even when the mobile phone is in silent mode, making it effective for detecting mobile...
Simple Field Strength Meter I Circuit
Useful for checking transmitters and antennas, this circuit utilizes a voltage-doubling detector consisting of diodes D1 and D2, which can be HP 5082-2800 hot carrier types or alternatives such as 1N34 or IN82. The circuit incorporates a 100-mA meter movement.
This...
field strength meter
This project involves a straightforward and practical moisture level LED meter circuit, which serves as a sensor or detector to measure humidity or moisture levels in various materials such as plants, soil, wood, walls, and floors.
The moisture level LED meter...
Field strength meter 1-150Mhz
The tuning range is determined by the dimensions of the coil (L) and the setting of the capacitor (C1). Coils can be either plugged in for multi-range use or soldered in place if only a limited frequency range is of...
bugs
Radio transmitters for eavesdropping on private conversations and sending video pictures, battery-operated.
Radio transmitters designed for eavesdropping applications typically operate within specific frequency ranges to capture audio and video signals discreetly. These devices often utilize low-power RF (radio frequency) technology to...
Field Strength Meter
This Field Strength Meter has been specially designed for our FM bugs. It is capable of detecting very low power transmitters and will assist enormously in peaking many of our FM transmitters that have a coil in the output stage...
AF2310 radio controlled motor circuit design project
This circuit resembles that of a car radio-controlled toy with seven control functions: forward, forward-left, forward-right, backward, backward-left, backward-right, and stop. Additionally, this radio frequency circuit can be utilized for other electronic circuits that require a simple wireless motor controller....
RF detector circuit diagram using transistors
This circuit responds to RF signals below the standard broadcast band up to over 500 MHz and provides both visual and audible indications when an RF signal is detected. By adjusting the bias of diode D2 with the R2 potentiometer,...
NSH Field Strength Meter
A well-tuned antenna system functions like a dummy load, meaning the Standing Wave Ratio (SWR) is 1.2:1 or lower; however, the effective radiation range is limited. The issue at hand is insufficient radiation. To diagnose this, one can measure the...
