We need technology for everything today , be it washing clothes, dishwasher for utensils, or getting medical reports. Our increasing dependency on technology round the clock has inspired the Chinese Technology Giant, Xiaomi to introduce a new product to the market.Yes we are talking about the new talk of the town, the electronic bicycle by Xiaomi, named “Qicycle”How Does it Work?The Qicycle weighs 14.5 kgs and 7kgs.Any other information is yet to be revealed by the Chinese company. But this is a new concept introduced by the company that lures people who love riding eco-friendly bikes, unlike this one the ... Read More

Earlier we had simple analog watches, then came the trend of digital watches, then the one with pulse check, heart rate and finally the smart watches. So, if you forgot your phone but have your smart watch, it’s OK. You can still receive all your important calls and messages. Anyways here we are not talking about the smartwatches but watches with some extra smartness. Confused?So let’s put it this way, imagine a watch that would use your hand as an interface. Your hand will be your ultimate watch, cool right? You interact with this interfaces outside the smartwatch. This is ... Read More

This is one of those things that are ridiculous but practically cool, and something only Sony would dare to make. A TV remote with speakers. It is currently only meant for the Japanese market, and might remain there. The Japanese are more open to technology and love the conveniences and the complications it brings with it.The LookA lot of people think it is bizarre, but then it’s not innovative until it’s different. And it is purposeful. The look is unlike any remote you have ever seen. Unlike the futuristic Apple TV remote which you will be losing all the time ... Read More

Plants are important to make a sense of balance between nature and in people’s lives. Being living organisms, they have a place in the vegetable kingdom that can live on land or in water. Plants and humans are mutually dependent for life and sustainability but are unable to share emotional bonds of each other.However, can you imagine that plants can even speak and feel the emotions of a human being? Yes, it is not just the imagination now. It can be possible. The gardeners can understand the thought of plants and can talk to them scientifically through a great research, ... Read More

A projector is a visual display unit that is used to project pictures and films onto a screen. Depending on the technology used, several types of projectors available such as LCD projector, LED projector, DLP projector, 4K Projector, Laser projector, etc. In this article, we will discuss about DLP and LCD projectors, and how they are different from each other. The basic difference between the two is that DLP projectors use a series of mirrors placed on a microchip that act as pixels, whereas LCD projectors use liquid crystals placed between two transparent electrodes and two polarizing filters. What is ... Read More

To communicate with the computers, we need some languages. These are computer languages.There are mainly three different languages with the help of which we can develop computer programs. And they are –Machine Level languageAssembly Level Language andHigh Level LanguageMachine Level LanguageComputer can understand only the language of Digital Electronics. Digital Electronics deals with presence and absence of voltages. Within the computer there are two logics can play their role. These logics are –Positive Logic – Here presence of voltage will be denoted by 1 and absence of voltage will be denoted by 0Negative Logic – Here presence of voltage will be ... Read More

It is a common complaint that electricity bills are at soaring high due to the consumption of so much electricity by Air Conditioners.Here are the top 5 reasons, which result in huge electricity bills.Dust in Air Filter: This has to be cleaned periodically as the dirty air filter can lead to overheating of motor and compressor.Leaks in the ducts: Leaks in the ducts make the thermostat work for a longer time which will increase the electricity bill.A problem in the parts: If there are any problems in the parts, then the electricity bill will go up.Old System: If the AC ...

Light can be obtained from various sources like candles, lamp and sunrays etc. Light bulb had invented by Thomas Edison in 1879. An electric current is passed through a filament inside bulb, it gets heated up and emits light when sufficient current is passed through the filament. That means it converts electrical energy into heat energy in the bulb. Where in Light Emitting Diodes (LED), electronic electrical energy can directly converted into light energy.Light is a energy which is released by atoms. Particles of light are photons which have no mass. Atoms are basic building blocks which are made of small ... Read More

A Bipolar Junction Transistor (BJT) is a three terminal circuit or device that amplifies flow of current. It is solid state device that flows current in two terminals, i.e., collector and emitter and controlled by third device known as terminal or base terminal. Unlike a normal p-n junction diode, this transistor has two p-n junctions. The basic symbols of BJT are n-type and p-type. Electronic current is conducted by both free electrons and holes in bipolar junction transistor.Terminals of Bipolar Junction TransistorsThere are three terminals in bipolar junction transistors are explained below.Emitter − It supplies charge carriers. It is highly ... Read More
