Connecting The Smart City
– Advertisement – We live in an increasingly urban world. The United Nations (UN) estimates that more than 55 percent of us live in an urban environment and predicts that this will grow to nearly 70 percent by the middle of the century. This population growth comes at a time when we as individuals have…
Arduino Projects: Ideas for Engineering Students
Embarking on a journey in engineering can be as exciting as it is challenging. For many engineering students, hands-on projects are invaluable for learning and applying theoretical knowledge. One of the most versatile platforms for these projects is Arduino, an open-source electronics platform. Arduino’s user-friendly interface and extensive library make it an ideal starting point…
Building a low-cost, precision digital oscilloscope
Editor’s note: In this DI, high school student Tommy Liu modifies a popular low-cost DIY oscilloscope to enhance its input noise rejection and ADC noise with anti-aliasing filtering and IIR filtering. Part 1 introduces the oscilloscope design and simulation. Part 2 will show the experimental results of this oscilloscope. A digital oscilloscope is one of…
Interesting Reference Designs Of Radar
Title of Reference Design Radar Sensor 2D Radar Transceiver Single-Chip Radar Sensor 24GHz Radar Sensor Short-Range Radar Image KeyAttractions The reference design offers motion detection, direction sensing, and smart power-saving in a compact design. It works through non-metallic materials, supports custom processing, and operates efficiently, making it suitable for battery-powered and embedded applications. The 2D…
Can a household manage on just 50 amps?
Today’s typical home is wired for at least 100-amp service, and many are wired for twice that number. This makes sense given the multiplicity of modern appliances and electronics in a home. The demand is obviously higher if you have an electric stove/range, or an electric vehicle using a basic in-house Level 1 charger. The…
Taking apart a wall wart
Topic themes Although in general I strive to cover a diversity of topics here in the blog, regular readers may have noticed that some amount of chronological theme-grouping still goes on. A few years back, for example, I wrote a fair bit about building PCs, both conceptually and in un-teardown (i.e., hands-on assembly) fashion. After…
Wi-Fi Sensing: Smart Tracking With No Wearables, No Cameras, And No Privacy Worries!
– Advertisement – What if tracking movement and actions indoors using just Wi-Fi, without any privacy concern? Channel state information-powered AI has the answer. Smart sensing becomes faster, lighter, and deployable on everyday edge devices. The Internet of Things (IoT) is revolutionising how we interact with our surroundings—from adjusting lights in a smart environment to…
EcoFlow’s Delta 2: Abundant Stored Energy (and Charging Options) for You
As I briefly noted back in mid-November, I ended up replacing my initial failed-experiment lithium battery-based portable power unit, Energizer’s PowerSource Pro Battery Generator: with two EcoFlow successors, the smaller RIVER 2: and this writeup’s subject, the DELTA 2, which I bought in claimed factory-refurbished condition (albeit, like the RIVER 2, also seemingly actually brand…
The Role of Vibration Monitoring in Alternative Energy
How Renewable Energy Runs Better with Smart Sensors (Source: Jack Tamrong /stock.adobe.com) Equipment failures in alternative energy systems can have serious consequences. A single pump malfunction could force an entire hydropower plant to go offline for weeks. In wind power, a gearbox failure does more than just stop the turbines—it can lead to dangerous and…
