What is 5G? The Complete Guide to When, Why, and How

The future depends on connectivity. From artificial intelligence and self-driving cars to telemedicine and mixed reality to as yet undreamt technologies, all the things we hope will make our lives easier, safer, and healthier will require high-speed, always-on internet connections. To keep up with the explosion of new connected gadgets and vehicles, not to mention the deluge of streaming video, the mobile industry has introduced something called 5G—so named because it’s the fifth generation of wireless networking technology. The promise is that 5G will bring speeds of around 10 gigabits per second to your phone. …

Build This IoT-Based Smart Home Controller Using Blynk

Advertisement Presented here is an Internet of Things (IoT)-based controller for a smart home. This project can be used to control any four home electrical appliances such as lights, fans, air-conditioners and water pumps from the smartphone. In this project, we used two light bulbs, one DHT-11 sensor to monitor room temperature and humidity, one soil moisture sensor along with garden motor pump, and one ultrasonic sensor (HC-SR04) for water-level indication in overhead water tank. Their status, including light on/off, room temperature, soil moisture level and water level, could be monitored on the smartphone graphically. …

Introduction to Various Types of Sensors

Advertisement Before working with sensors on any project, we must know its usage, advantages, limitations, and characteristics. There are various parameters on which various types of sensors are chosen for any particular application like cost, size, weight, resolution, sensitivity, etc. In this article, we would be going through various types of sensors in details along with various sensor types available in the market like: Position Sensor It is a type of sensor that can detect the object movements and converts them into signals suitable for processing, transmission, or control. Typical applications for position sensor is …

Zoom’s latest changes to prevent ‘zoombombing’ arrive on May 9th

Zoom is implementing more of its promised measures to bolster security and prevent “zoo bombing” by unwanted guests. To start, it recently gave admins the option of disabling personal meeting IDs for scheduling and starting meetings. An intruder who discovers the ID can’t use it to host a videoconference. On May 9th, basic (aka free) accounts will need to use passwords for all meetings. Waiting rooms and host-only screen sharing will be on by default for these free users, too. These changes come well into lockdowns for the COVID-19 pandemic, and too late for a …

Haptic Touch doesn’t work for notifications on the iPhone SE

As capable as the new iPhone SE might be for the money, there’s one software quirk that could sour the experience for some. Users on Reddit, MacRumors and elsewhere have discovered that you can’t use Haptic Touch (that is, a press and hold with vibration feedback) for notifications on the lock screen or Notification Center like you can with the iPhone 11 series. And like TechCrunch’s Matthew Panzarino noted, this is apparently intentional in its current form — at the moment, there are no known plans to patch the functionality. We’ve asked Apple for comment. …

The Complete History And Future of Robots

Modern robots are not unlike toddlers: It’s hilarious to watch them fall over, but deep down we know that if we laugh too hard, they might develop a complex and grow up to start World War III. None of humanity’s creations inspires such a confusing mix of awe, admiration, and fear: We want robots to make our lives easier and safer, yet we can’t quite bring ourselves to trust them. We’re crafting them in our own image, yet we are terrified they’ll supplant us. But that trepidation is no obstacle to the booming field of …

Galaxy S20 Ultra review: Impressive but impractical

Faster screens Although watching 8K videos on the S20 Ultra is silly, it’s still a lovely canvas. The cityscapes I shot looked crisp and colorful on the Ultra’s 6.9-inch screen, even in sunlight. I also enjoyed watching a couple of 4K HDR videos and endless Instagram posts about my friends’ exciting lives. Plus, the Ultra’s almost all-screen front made the viewing experience more immersive and inviting. One of the highlights on the S20 series is their 120Hz displays, which allows them to refresh much faster than other phones. So far, only the Razer Phone 2, …

Automatic Anchor Light

Advertisement Federal and international regulations require boats to carry lights between sunset and sunrise and during conditions of restricted visibility. The number and colors of the lights vary with the size of the vessel. Many commercial vessels carry special lights that identify them to the others. This is important because the right of way depends on the types of vessels involved. Tugs and commercial fishing vessels have the right of way over sailboats, which have the right of way over ordinary power vessels. Fig. 1: Anchor light position at the top of a mast Unique …

What Is the Internet of Things? A WIRED Guide

Most of the early smart home inventions used automatic controls, making it possible to turn something or off without lifting a finger. But they didn’t connect to anything else, and their functionality was limited. That would begin to change in 1983 when ARPANET, the earliest version of the internet, adopted the internet protocol suite (also known as TCP/IP). The protocol set standards for how digital data should be transmitted, routed, and received. Essentially, it laid the groundwork for the modern internet. IoT Through the Years 1990 John Romkey creates the first IoT device: a toaster …
