Electronics For You August 2022 Issue Vol. 54 No. 8 Strategy GROWTH: India’s Electronics Industry: How’s It Doing? Supply-chain problems, lack of manpower, fluctuating dollar, and inflation are a few of the challenges being faced by India’s electronics industry. Increased demand, expanding customer base, and growth in indigenous manufacturing are some of the blessings for India’s electronics industry. So, how’s the sector actually doing? Has it recovered post-Covid or not?
Do-It-Yourself PROJECT: API Server On ESP8266 Using MicroPython MicroPython is similar to Python 3, but it is meant for microcontrollers. MicroPython comes with an interactive Read-Evaluate-Print-Loop (REPL), which is an amazing feature that allows us to connect to a microcontroller, execute code quickly without the need to compile or upload code, and gives immediate feedback. Also, most importantly, the community support available for it makes the use of this firmware easier	Do-It-Yourself PROJECT: A Remote Without Battery That Can Work For Years There is huge chemical waste being generated by billions of batteries used in remote controllers for electronic devices like TV sets, set-top boxes, air-conditioners, and even some ceiling fans now-a-days. The waste produced by their spent batteries keeps increasing annually

Strategy INNOVATION: How We Can Innovate Better Real innovation is becoming scarce day by day. It is being replaced by fund-raising celebrations. There is no dearth of problems or issues to be tackled; instead, most of them spend a large portion of funds on rebranding, marketing, and serving unsustainable claims	Strategy MY STORY: “Inquisitiveness To Explore Makes A Big Difference...” — Dr Aloknath De, FNAE, Executive Consulting Director, Samsung There are many who aspire to hold prestigious positions at big corporate houses, but very few are willing to work hard enough for it. Such positions can be achieved by only those who love what they do. Dr Aloknath De is one of them. He calls himself a ‘missionpreneur.’ He refuses to box himself and loves to think out of the box. He does not become comfortable in a setting as he likes to do things outside his comfort zone. He has been Samsung India’s first CTO besides many more achievements to his credit. This is Dr Aloknath De’s story, as told to EFY’s Siddha Dhar

Strategy Open Source: The Open Source Wars This article looks at how difference of opinion between developers and users of open source software has led to competitive battles, with some software emerging victorious and dominating over others	Technology CAREER: Skills You Need For Becoming An Ethereum Blockchain Developer Ethereum is a popular blockchain platform that offers quite a few lucrative job opportunities.

Technology TRENDS: How Mobile Phones Have Evolved And Lead To Newer Innovations It’s a pretty exciting time for mobile architecture since the world is currently struggling with the gradual decline of Moore’s Law. In his keynote address at the VLSI Design Conference 2022, Ken Wiseman (VP - Technology, Qualcomm) talked about mobile architecture, the existing challenges, and how the mobile architecture has led to newer innovations	Technology TRENDS: Will Lithium-Air Batteries Replace Lithium-Ion Batteries In Electric Vehicles Soon? The extremely high theoretical energy density of lithium-air batteries encourages researchers to develop commercially viable batteries. However, the gap between idea and reality is still big. The challenge lies in improving the cycling stability under complex superoxide/peroxide containing situations while keeping a good energy efficiency and rate capability. The batteries are undergoing high-speed development and admirable breakthrough in improving their electrochemical performance

Technology TRENDS: India’s Anti-Satellite Programme: New Opportunities For Industry Just imagine an Indian spy satellite intercepting enemy signal that indicates imminent land, sea, air and cyber-attacks on critical defence positions and installations. The Chief of Defence Staff (CDS) holds an emergency four-way conference with ground, sea, and air commanders thousands of kilometres apart through a satellite phone. Low-orbiting surveillance satellites locate the enemy battle formations, radar installations, and missile pads. The army formations, combat aircraft, and nuclear submarines get into action using navigation and communication satellites. This was one of the scenarios played out in India’s first simulated space warfare exercise, IndSpaceEx, conducted recently by the Indian armed forces. The exercise provided all stakeholders a deep understanding of the emerging space security challenges to review the existing resources and plan appropriate defence capabilities and assets in space	Design EMBEDDED: HarmonyOS: An Operating System Running Ahead Of Its Time Every smart device today runs on some form an operating system (OS) but often some of the devices being used run on different OS. This makes it hard to integrate them and make the devices communicate with each other to accomplish a particular task. HarmonyOS brings this nuisance to an end while supplementing the overall user experience. Read on for further information on the subject

Design CIRCUIT: Step-By Step Guide To Select Power MOSFETs Metal oxide semiconducting field effect transistor, commonly known as MOSFET, is a voltage-controlled device that is normally used as a switch or amplifier. It is considered one of the most crucial electronic devices in bringing about the modern electronics revolution. This semiconducting switch finds application in a wide variety of operations, especially where power conversion takes place. However, a power MOSFET remains one of the most common causes of failure of high-power circuits like converters and inverters. Failure of a power MOSFET can be due to various reasons, but the most frequent is selection of a wrong power MOSFET for the application. This article covers the different types of MOSFETs and factors to consider while selecting a power MOSFET	Design T&M: Things To Keep In Mind When Selecting An Oscilloscope An oscilloscope is an indispensable tool for testing and analysis in a wide range of fields and applications. It is an essential instrument for anyone who designs, develops, or fixes electronic equipment. Therefore, it is imperative to be familiar with the ‘scope-jargon’ and be able to select the right one for your application

Do-It-Yourself CIRCUIT IDEA: A Simple But Versatile Musical Horn This simple musical horn can be used in a car, scooter, cycle, or motorbike, or even as a call-bell. It uses melody generator IC UM66 that generates a musical tone, which is amplified by IC LM386. The tone of the horn cannot, however, be changed as no potentiometer has been used to keep the circuit simple	Do-It-Yourself CIRCUIT IDEA: Sinusoidal Signal Generator With Forward And Inverted Outputs During the testing of audio systems and telephone-like systems, it is useful to have a sinusoidal signal generator that produces forward and inverted signals in the range of around 15Hz to 15kHz. Here is one possible way of making that signal generator

Do-It-Yourself CIRCUIT IDEA: A Simple Wireless Charger For Smartphones Smartphone batteries need to be charged frequently, generally more than once a day. But their charging cables tend to get damaged after some time due to excessive use, which can be annoying—especially if they fail when these are needed the most. A wireless charger can be a convenient alternative; you simply set it up and forget it	Regulars Dashboard Key Industry Trends That Can Shape The Future Of Your Business
