Electric vehicles are the future of the automotive industry. There are already more than 2.5 million BEVs and PHEVs in the United States this year, which is expected to increase. There are more than 2.3 million electric vehicles (EVs) in Europe. In India, the number has surpassed 1.3 million.  Battery aside, one key factor to a successful…

An electronic speed controller (ESC) is a vital component of a First Person View (FPV) drone. A drone’s propulsion system is built from three main components: The flight controller The electronic speed controller (ESC) The drone motors  The flight controller receives signals from the radio transmitter and sends signals to the ESC. Accordingly, the ESC…

Industrial robots are designed for use in industrial automation. They’re programmable machines that are specifically used to automate production-related tasks. Typically, several robots are installed in an assembly line, each responsible for a specific objective. For example, some pick and place workpieces, some interact with different equipment (such as a lathe or milling machine), and…

Are you building something that requires a GSM/GPRS modem or looking for a GSM modem for your next IoT project? GSM modems are widely used in several connected devices and applications. GSM is an acronym for Global Systems for Mobile, and GPRS refers to a General Packet Radio Service. A GSM module is a device…

The Internet of things (IoT), which includes the billions of devices now connected to the internet, has developed substantially over the past few years. IoT has become integral to several technologies and businesses. In fact, the number of active IoT devices has increased from 11.28 billion to 13.14 billion between 2021 and 2022. And the…

Computer vision is reaching new levels, far beyond basic image processing. This is thanks to the integration of artificial intelligence. AI now enables computers and systems to derive meaningful information from digital images that can be used in advanced industries. Currently, one of the most common applications is in security and surveillance.  A computer vision…

In previous articles (including here, here, and here), we discussed the different types of filters available, including examples. If you’ve followed along, you should have an understanding of the frequency components (i.e., attenuating high frequencies when using a low pass filter and the passing frequencies for a high pass filter). You should also be aware…

The embedded software or firmware is the brain of an embedded device. However, this type of software works differently than the conventional ones on PCs or mobile devices — which are generic and work identically on such operating systems. PC software runs without directly accessing the underlying hardware. The purpose of embedded software works in…

Machine learning (ML) and artificial intelligence (AI) are no longer limited to high-end servers or cloud platforms. Thanks to new developments in integrated circuits (IC) and software technology, it’s possible to implement ML algorithms and deep learning neural networks on tiny controllers and microcomputers. And these embedded devices installed at edges must no longer rely…

A polygraph is an instrument that records physiological indicators like pulse rate, blood pressure, and electrodermal activity of a human subject under questioning by an operator. It’s commonly referred to as a lie-detector test because it’s designed to assess whether a person is telling the truth. Industry-standard polygraph equipment is said to be 80 to…

Microcontrollers are the workhorse behind most embedded systems. They serve as a compact integrated circuit (IC) designed to govern a specific operation in an embedded system. The programmable firmware used in these tiny computers is ideal for and fits well into several applications. Microcontrollers are neither too specific, like application-specific integrated circuits (ASICs), nor too…

Bandpass and band reject filters have the combined benefit of both low- and high-passes. They are made by connecting the low-pass and high-pass of different cut-off frequencies. It is beneficial when you require or want to reject only a particular band of frequencies. They are used heavily in investigating audio released from a black box…

Modbus is a popular low-speed serial communication protocol widely used in the automation industry. The protocol was developed by Modicon (now acquired by Schneider Electric) in 1979 for its own programmable logic controllers. The protocol served as a link between PLCs and intelligent automation devices. Now an open protocol maintained by Modbus Organization, the Modbus…

Drone industry is growing at a fast pace. Drones have been adopted in several verticals, including real estate, healthcare, military, transport, surveying, retail delivery, construction, and infrastructure. There are 1.1 million drones registered with Federal Aviation Administration in the United States. There are more than a million active drones in India. There were 430,700 drones…

Electronics manufacturing is possible thanks to electronic design automation (EDA) software. EDA has computerized and automated several processes in product design and production. While some tools focus on circuit design and simulation, others target design analysis, verification, and manufacturing preparations. Each tool provides a unique package optimized for electrical and electronics engineers. Although no tool…

Automotive engineers have already developed semi-autonomous vehicles. Fully self-driving vehicles are not far from reality. According to recent research, autonomous driving (AD) could create $300 billion to $400 billion in revenue by 2035. The self-driving car not only showcases how advanced technology is, but it’s also a subject of controversy. There are valid concerns about…

India launched its first indigenous drone traffic management system in February 2023. The system is Skye UTM, developed by Skye Air Mobility. Skye Air Mobility is a leading drone delivery company in India. It has been streamlining drone delivery services in multiple logistics solutions, including e-commerce, Agri-commodity,  quick commerce, healthcare, etc. UTM, which stands for…

Robots got their name from a Czech word “Robota” which means slave or any mechanical item that can help its master. Robots are mechanical devices that help to perform specific tasks for the humans. The term ‘Robot’ can be used for any mechanical device equipped with the software-based intelligence to perform specific physical tasks.The robotic cars or robotic vehicles are one of the many robotic designs which are developed to move around for performing physical tasks. The motion of such robot itself involves the application of power and use of motors. In making such a robot, there needs to be a balance between the load (weight of Robot), Battery and Motor used.

Previously, we discussed open-source 3D printable humanoid robot projects. Now, we’ll cover the top 3D printable robotic arms. A robotic arm is a pick-and-place robot typically used in manufacturing assembly lines. They’re also used for CNC, laser engraving, and 3D printing.  The robots are designed to repeat specific tasks with the highest accuracy and precision. Servos electronically…

Servers are no longer limited to corporate offices and are common in homes. They can run 24×7 on any low-cost PC or microcomputer.  A home server manages online communication, internet browsing, downloading, and file sharing between computers, tablets, mobile phones, printers, and other smart home appliances. They can also serve as centralized media storage for…
