Artificial intelligence (AI) and machine learning (ML) are continuing to become more mainstream and you’ll find the technology in everything from your smartphone apps and computer programs to smart tech and appliances — and automobiles (think self-driving cars). These technologies are no longer confined to scientific computing and statistical research but have, for the most part, become a […]
What is 3D scanning?
Since 3D scanners have become more affordable, 3D scanning has changed the world of custom 3D printing. Once, 3D scanning was only used in military equipment and spacecraft parts production. With desktop and handheld 3D printers available for a few hundred dollars, 3D scanning has found a place in home fun and hobby projects. You […]
What are some common EMI/EMC tests?
An EMC test is known as Electromagnetic compatibility, a certification for electronic devices to maintain their limitation of electromagnetic waves. As discussed in the previous article, there are two types of EMC tests: emission (EMI) and immunity (EMS). EMI (Electromagnetic Interference) tests measure the magnetic waves emitted by the device, and EMS (Electromagnetic Susceptibility) tests […]
What are different types of biometric sensors?
The term “Biometrics” is derived from “bio’” which means life, and “metrics”, which means measurement. Biometrics is developing for use in various technologies, including the unique identification and recognition of people. The technology at its current juncture is widely used in security and surveillance systems. Biometrics also has the possibility of converging with other technologies […]
Introduction to Raspberry Pi 4
Raspberry Pi is a credit-card-sized, single-board computer developed by the Raspberry Pi Foundation, a UK-based charity that works to ensure global access to computing and digital technology. It was initially developed as a low-cost microcomputer to impart digital skills to kids. It comes without any power supply or peripherals as it’s meant to be programmed […]
What are the different types of fingerprint scanners?
Fingerprint scanners, which were once reserved for biometric logging systems and attendance systems, are now part of regular smartphones and much more. Fingerprints have been a trusted method of personal identity. Combined with face id or other biometric identification systems like retina scanning, fingerprints offer an impeccable way to recognize any person. With a blast […]
What is IOTA?
IOTA is a cryptocurrency designed to add economics to the internet of machines. IOTA is quite different from thousands of other cryptocurrencies. Some key highlights of IOTA are as follows: IOTA is specifically designed for the Internet of Things. IOTA does not use blockchain technology; instead, it is based on Tangle technology. IOTA has theoretically […]
The pros and cons of the Raspberry Pi 400
In many ways, Raspberry Pi falls short as a full-fledged personal computer. The Raspberry Pi Foundation has tried to change this with its latest addition, the Raspberry Pi 400. Launched in November of 2020, the Raspberry Pi 400 is a single-board computer in the form of a keyboard, retailing at $70 per unit or $100 […]
How to design an Arduino-based EMG monitor
Electromyography (EMG) is a medical procedure that evaluates the health conditions of muscles and nerve cells. These cells transmit electrical signals that cause muscles to contract or relax. EMG is used to read these signals and plot them as numbers or graphs. Typically, EMG is performed by doctors as one part of a diagnostic tool […]
What are the AMBA protocols?
As electronic miniaturization has been an all-time goal of chip manufacturers, motherboard-based computer/electronic systems have been eventually replaced by System-on-Chip (SoC) and Package-on-Package (PoP) ICs. Complex computer systems are now condensed to smartphones and other handheld devices. These sophisticated electronic devices and gadgets have an SoC at their heart which manages complete computing and control. […]
