Electromagnetic (EMC) shielding prevents damage to electronic components by protecting PCB elements and associated hardware from electromagnetic interference (EMI). Robert John Webber, field application engineer, Harwin, discusses the role of interconnect devices and EMC shielding in manufacturing in an...
Clear solar cells in greenhouse roofs could generate electricity while plants grow below. Because the visible and the infrared (IR) regions of light take up about 47 and 51 per cent of energy in the solar spectrum, respectively, utilising visible...
Presented here is an Internet of Things (IoT)-based temperature monitoring system using IBM Bluemix cloud platform and Mbed NXP LPC1768 development board. Developed by IBM, IBM Bluemix cloud platform supports several programming languages and services as well as integrated DevOps...
This is a computer based Break Timer program to remind you to take regular breaks while working on your desk for good health. Some of us spend at least sixty per cent (if not more) of our day sitting...
This simple GSM security switch project is based on Arduino Nano microcontroller (MCU) and SIM800L GSM modem (Fig. 1). The cellular-based alert system is configured to send an SMS in response to a security switch action. When the security sensor...
LM317T and LM337T ICs are well-known, low-cost adjustable voltage regulators capable of delivering up to 1.5A current output with power dissipation of up to 20W. LM317T produces a positive output voltage, while LM337T produces a negative output voltage. It is...
A power supply converts AC voltage into regulated DC voltage. Read on to find out how to select the best power supply for an electronic device. A power supply for an electronic equipment is a circuit that converts AC voltage...
India has consistently suffered from a high number of criminal activities and law violations over the years. Official records suggest that 70 per cent of these incidents involve repeat offenders. For the longest time this kind of data remained...
Presented here is a MATLAB-based program for image compression using discrete cosine transform technique. It works for both coloured and grayscale images. Over the last few years, messaging apps like WhatsApp, Viber and Skype have become increasingly popular. These applications...
Demand for medical devices is growing at a fast rate as people become more and more health conscious with increasing government-aided social healthcare schemes and an increasing number of patients moving from hospitals to their homes for nursing and...
