Chip resistors are also known as surface-mount devices or SMD resistors. Chip resistors are manufactured using metal oxides or metal films, and are protected using robust coatings. These are small and mostly available in square or rectangular chip packages. Unlike through-hole-technology (THT) resistor devices, SMD resistors do not have leads. These are mounted directly onto […]
Automation is gradually becoming a part of our everyday life. With new improvements, not just our lives, but the operational quality of automated machines such as robots is becoming enhanced to the extent that they may not require any human mediation at all. Robots are adept in carrying out pretty much any task that a […]
Geofencing is one of the greatest technologies of the 21st century. It has a multitude of applications such as car tracking and parcel location tracking. Here is a more exhaustive list of the applications of geofencing Can be used for livestock and other animals to track their movement Can be used to monitor prisoners or […]
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 switch input recognises an event, the system sends a customised alert message to a predefined […]
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 useful to have a bipolar power supply with LM317T and LM337T producing symmetrical output power. […]

COVID-19 is a highly infectious and easily contractable virus that can become extremely hard to control once it begins to spread. Social isolation/distancing is one of the most important and effective steps one can take to break the chain and to keep healthy people from getting infected. If an infected person comes into contact with […]
This is a concept DIY that helps to detect the symptoms of COVID-19, so as to help individuals quarantine themselves and practice social distancing.The DIY works by detecting the basic symptoms of the virus, which are: increased body temperature and shortness of breath. Although it is not necessary that shortness of breath will cause low […]
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 let users send and receive text messages and videos. All of us make extensive use […]
An antenna is an electrical device which converts electric power into radio waves, and vice versa. Antennas are essential components of all equipment that uses radio. They are used in systems such as radio broadcasting, broadcast television, two-way radio, communications receivers, radar, cell phones, and satellite communications. Antennas can be classified in various ways. Introduction It is a source or radiator of EM waves, or a […]
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 into regulated DC voltage. An electronic device does not normally use electric energy in the […]
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 offline, even when it was spread across different zones and states. Identifying this major challenge law […]
Taking blood tests is the first step in evaluating and detecting diseases, ranging from viral fever to parasitic illnesses like malaria and dengue, and complicated diseases like blood cancer and HIV. Pathology labs in India are always on their toes because of the high volume of test samples collected daily. Performing morphological and quantitative tests, […]
Sipeed, maker of the dev board, aims to promote rapid and effortless creation of IoT and Deep Learning-based DIY projects. Due to a rapid increase in the number of connected devices, the demand for privacy/confidentiality, low latency and bandwidth constraints has compelled AI models to be trained in the cloud and be run at the […]
Humans and machines behave in very different ways when it comes to doing simple tasks. That does not mean both cannot work together, as proved by the following experiment where a robot learns how to resemble the hand movements of a human when grabbing an object. Automated mechanical system, also referred to as a robot, […]
Observatory doors are quite heavy and weigh several kilograms. This requires a strong, automated mechanism to move them. Such was achieved by employing a commonly used DIY board that consumed only a fraction of household power. A dome-shaped observatory housing an optical telescope is often built on a high altitude location, where the surrounding air […]
Solar streetlights can be easily integrated with a dusk-dawn controller by simply employing a pnp transistor and a few resistors where the solar panel itself works as the sensor. But what about other lighting sources that do not employ solar panels such as automatic lighting systems in small wind turbines, automatic lighting in cars or […]
