I deliberately didn't write about it right away, and at the beginning there wasn't really much to say anyway. But I've finally decided to try to revive my channel, and there are already three new videos up.

Hong Kong hosts the Hong Kong Electronics Fair every spring and autumn. In scale, it is comparable to Germany’s IFA and even the US Consumer Electronics Show. In September, the exhibition takes place alongside electronicAsia, a trade fair for information technology and communications. Both events are organized by the Hong Kong Trade Development Council (HKTDC) and MMI Asia Pte Ltd.

A new Xiaomi Xiaowa robot vacuum cleaner has recently hit the market, and it is quite feature-packed for its price. A few days ago, the new Roidmi F8 handheld vacuum cleaner became available for pre-order. I wonder if it can compete with the big manufacturers? I've been using Xiaomi products for several years, and I'm sure this handheld vacuum will be powerful enough to handle, for example, pet hair.

3D pens have been gaining popularity lately, but quite a lot of people still have only a vague idea of what they are and what they’re for.

The Sun is an indispensable star in our solar system. Every day, it brings light, warmth, and an enormous amount of energy to our planet. Over time, the Sun became more than a source of life-giving energy for us: it became a source of energy for industry and other human activities (for example, solar panels). Since this energy can be considered “clean” (it does not pollute the environment), harnessing it has enormous potential.

Although smartphones are becoming more advanced and feature-packed every year, they still have some drawbacks. One of them is how long their batteries last. Usually, the more features a device has, the faster it runs out of charge. This means many of us have to carry various chargers with us almost all the time—which isn't always convenient.

Wi-Fi technology is widely known and used almost everywhere. As technology has advanced and internet access has become easier, many people have started using its capabilities virtually all the time. On average, people around the world spend more than 5.5 hours a day “online,” and few stop to consider that Wi-Fi technology could be used for some other purpose.

Who hasn’t ever stepped outside and realized they’d picked the wrong clothes for the day? This situation is so common that it could even be considered one of humanity’s “global” problems. When it’s cold, you can still put something over your outfit (a blanket, for example), but when the weather is warm or hot, that isn’t always an option.

Lately, we keep being amazed by how many of our technological fantasies continue to come true. First and foremost, of course, we have the creativity of famous writers, artists, and screenwriters to thank for this. Drawing inspiration from their work, we are moving closer to the vision of the future we imagined for ourselves many years ago.

These days, people often struggle with a lack of physical activity. Many will recognize this routine: they wake up, go to work, spend 8-9 hours sitting, then come home and spend another 4 hours sitting (in front of the TV or computer). This kind of lifestyle cannot go unnoticed, and it does nothing to benefit a person's health. More and more people are beginning to realize this and switch to a healthier lifestyle.

Humans were the first beings on our planet to invent music. Music has been, is, and will remain an important part of human life. Throughout history, it has evolved, changed styles and playback methods, yet it has always held special significance for people.

Today, humanity strives for optimization, comfort, and simplicity. These impulses drive us to take a fresh look at everything around us, spot shortcomings and bottlenecks, and automate and improve them. One common shortcoming is an inconvenient shape or size. As a result, we have already made computers smaller and their displays thinner without sacrificing performance.

Virtual reality is a human-created information and technology-based world that responds to interactions with it and conveys changes back to the user through various senses. This field is becoming increasingly promising and is already being used in areas such as education, video viewing, and gaming.

The idea of generating energy from solar panels is widely known and is being steadily adopted by many developed countries and major companies. Thanks to the active rollout of this technology, we already have solar-powered watches, solar-powered lights, umbrellas, and various types of furniture with solar panels built in. But one of the “breakthroughs” in the use of solar energy was Solar Impulse—the first aircraft powered entirely by solar energy. It was first unveiled back in 2009 by its creator, Bertrand Piccard.

Batteries are devices designed to store electrical energy and repeatedly power various electrical appliances. Our world is surrounded by power grids and, to a large extent, automated with electrical equipment. So each of us uses different types of batteries to some degree.

“Smart” TVs have only been on the market for a relatively short time, and not everyone knows the difference between a “smart” TV and a regular one. A regular TV is a device that lets users receive and watch specific channels with the programs they carry, while a “smart” TV also has access to the Internet through special apps.

Scientists at the Karlsruhe Institute of Technology in Germany have developed a new 3D printing method that can use glass. The method was dubbed "liquid glass" because it consists of tiny glass nanoparticles suspended in a photopolymer binder. When exposed to light and heat, the mixture transforms and hardens into the shape specified in the settings, making 3D printing possible.

Flexible displays have been on the radar of many people interested in technological progress for a long time. Yet until quite recently, flat screens were the focus of all the attention and admiration. Over the past 10 years, since the idea was first mentioned, many companies have shown the public their projects for creating flat screens (in most cases, for smartphones).
