TV | FM Antenna Installation

Engineeering Projects
matching antenna to receiver

TV and FM antenna installation practices will be preferred to throughout this discussion. Installing TV and FM antennas portrays fairly standard practices that should be followed when doing any kind of communications antennas installation. Never neglect safety. Standard operation procedure should always make safety first on the list of things to do. Locate power lines, telephone lines, and obstacles that could interface with the installation or present a hazard to the installers. A tower structure would require a concrete base as the supporting structure. Guy wires need room for proper…

How to Test Crystal Oscillator

Engineeering Projects
testing of crystal oscillator

Here is the procedure of testing crystal oscillator, oscillator capacitor and oscillator inductor. In a previous article we had posted a circuit called universal crystal oscillator tester for testing crystal oscillator. Now we had posted simple method which is summarize in few point on How to Test Crystal Oscillator below. An oscillator with a bad crystal may not oscillate at all, may be erratic, or may not oscillate at the correct frequency. One common crystal failure mode is a broken or corroded internal connection. Or if the crystal has been dropped,…

Accident Detection and Alert System using Arduino

Engineeering Projects
author prototype of accident detection system

Today in this article we are going to build a project called Accident Detection and Alert System using Arduino UNO, GSM module, GPS module, and Vibration Sensor Module. The vibration sensor module used in this project is used to detect the change in linear velocity, displacement, or acceleration. The GPS module detects the exact location (longitude and latitude) and the GSM module is used to send all information to the mobile number assigned in the software code. You may also like the Car Lock System using Arduino and GSM modules.…

Problem and Troubleshooting of Power Supply

Engineeering Projects
switching power supply troubleshooting

Power supply has a considerable role in electronic communications equipment. The power supply furnishes the voltage and current requirements for electronics circuit operation. Special high-voltage power supplies used in microwave systems and laser systems enable large power handling tubes and semiconductor circuits to operate. In this section, we are going to look at popular types of power supply circuits and some faults that can occur in them. In this section, we’ll also learn to troubleshoot a traveling wave tube amplifier. Improper operating of a TWT can nearly always be traced…

travelling wave tube amplifier troubleshooting

Before continuing about troubleshooting of traveling wave tube amplifier we have some initial considerations include: To make construction of the tube RF output circuit simple, the collector and helix are grounded. The cathode will be above ground and have a negative voltage on it as shown in figure 1. The helix is delicate and helix current will be small. The collector draws nearly all the current. The helix will be protected with an over current relay that kills the power supplies. Never defeat this relay because the tube can be…

arduino and rfid based attendance system circuit

The project Arduino and RFID Based Attendance System is simple and is used at any place where attendance is taken for maintaining the register. Previously we had posted a project using RFID and microcontroller AT89C52 called RFID Based Security System using Microcontroller AT89C52 used for the open door. Similarly, Arduino and RFID-based Door Access System RFID (Radio Frequency Identification) uses an electromagnetic field to detect unique tags assigned to object in the vicinity. An RFID tag is more secure and conventional because RFID traces tags hidden inside objects, unlike bar…

distance measurement using GPS and ATmega328

Whenever we thought about distance measurement, an image of a circuit designed using an ultrasonic sensor is formed in our minds. But today we are going to present here a distance measurement project using the GPS (Global Positioning Measurement) module. The project named DIY Distance Measurement uses GPS and ATmega328 which measure the distance between two positions using the haversine formula. The start point is the position where switch SW1 (Reading Switch) is pressed and the endpoint is the position when switch SW2 is pressed (Switch Switch). Thus, the circuit…
