Does Electronics Really Help Us

Electronics is a vast stream. The subject is pervasive in itself. Electronics are the primary source of almost everything that is happening today. The whole working of the items is dependent mainly on the electronics base. In our daily lives, we can see uncountable examples of the number of electronics used around us. From our environment itself, we can see how electronics can find their use in so many work departments. Human beings are slowly becoming addicted to the use of electronics in their lives. They have become almost dependant on the machines for their work. For example, the computer is the most commonly used machine, which is the best illustration of electronics in our lives. People have started being dependent on these machines to a large extent. All the work that was earlier known to be done by the people is now seen as to be done by the various devices and also the computer. Such is the help provided by the electronics to the people in their lives.

Simple logic analyzer for hobbyists

Logic analyzer isn’t a “must have” tool, especially for hobbyists. Most measurements of logic signals can be made with oscilloscope. But it doesn’t hurt to have one especially it costs cents literally.

Free fast and useful java based circuit simulator

Sometimes it is better to see one time than try to imagine things – especially in electronics. When designing something in electronics, it is probably the best way to take some circuit simulator and make a simple model see how it works before putting it into real worlds design. If you want to create complex circuit simulations, you probably should choose professional Spice based electronic circuit simulation tools. But what if you need a simple “pocket-sized„ simulator that would remind you of simple basics of how circuits work, how current flows in one or another situation. For this, you should try this Java-based circuit simulator.

Simple ways to save energy

Energy is a central economic factor for any country and especially for any household in any nation. Governments consider energy both as an economic impulsion and as a political factor that can generate the much-needed votes for any major election – consider the election of Barrack Obama’s election, the United States President. However, while these governments seek more energy, not all of them, in fact, a few, consider Ways to save energy. That has always been left to the homeowners and business holders who have more to lose in terms of money if they don’t like device simple time tested ways to save energy. For such, the simple ways to save energy are given because as earlier said, they have more to lose. Monitor the meter They say that it is important to know your enemy before you set out to fight him; the same applies to your home or business’s energy input devices. You need to understand the amount of energy that your home or business uses per month. This will offer you a valuable indicator of how much used and how much can be saved per month. Moreover, it will be important to do walking around to ascertain…

Robots home helpers taking over a work load

Domestic robots or home helpers can be used for household chores like vacuum cleaning and serving guests. Science inventions and technological breakthroughs have enabled the use and help of these artificial human beings to be greatly received and appreciate for the ease at which they are making be. Some people are even demanding much more improved robots that can actually think and do things just like a human in a more natural way With the trend and emergence of more technology, it is presumed that robots that are home helpers will be more common shortly than it has ever been seen. Right now, the most commonly used robot home helpers are vacuum cleaners. The vacuum cleaners use an air pump to create a semi or partial vacuum to suck up dust and dirt from the floors. The collected dirt and dust are also stored in the dust bag or cyclone for future disposal. These robots home helpers are actually creating and making work much easier and faster as well as efficient. All one needs to do is control the vacuum cleaner as it collects all the dust from the floors or tables and leaving them spotlessly clean

Molecular Transistors will make breakthrough in electronics

Nobody can doubt scientists’ effort when it comes to transistors and their importance in modern technological advancements. Over time, transistors have been in the market, designed from singular molecules. Electron flow in these transistors has been facilitated by the modulation of energy produced by molecular orbits or orbital. This behavior has greatly influenced the genesis of current and future molecular transistors and other devices. Since transistors (integration of circuit elements) work with the electric current flowing within the electrodes (drain and source electrodes), trying to improve voltage put to the 3rd electrode, normally referred to as gate electrode, the manufacture of these transistors takes time, money and energy. Determination by scientists and researchers so far have a fruit; they have made a breakthrough with the first molecular transistors being made. This transistor brand is made from one molecule, has its benzene molecule bonded to the vibrant gold contacts, and works or performs like the silicon transistors. The presence of varying energy degrees in the molecule can easily be manipulated by varying states of energy. Through this, you can be able to assert yourself in controlling the passage of current via it.

Nuclear Reactor Types – Are they really safe?

The nuclear power industry and reactor technology have constantly been developing for more than five decades now. Nuclear reactors can be classified based on their nuclear reaction, the moderator material used, generation of the reactor, fuel phase, fuel type, coolant used, etc. The fusion nuclear reactors are mainly dealt with because the fusion reactors are still in the developing stages, and the fission reactors are already being used for the past six decades. Based on nuclear reaction This type refers to the thermal (slow) reactors and the fast reactors based on neutrons’ speed. Thermal reactors are the most affordable and ordinary as they use natural and raw uranium. The neutrons are decelerated from their natural rate when emitted from the broken atomic nuclei and moderated material in the process. Fast reactors are costly that require more enriched fuel.

Full Body Scanners – How do they work?

The new full-body security scanners might become a popular alternative to body searches with the increased alleged terror threats worldwide. The full-body scanning system has taken the world by surprise in the past recent months. The most advanced method of whole-body imaging technology involves scanning the whole body through clothing, revealing both metallic and non-metallic hidden objects, including weapons or plastic explosives. The U.S. Transportation Security Agency (TSA) had already tried this concept of whole-body imaging at six airports in mid-2009 to look for threats that typical metal detectors could not find. The process to install these scanners at more airports in several U.S. cities is already heading rapidly, with the recent alleged unsuccessful terrorist attempt on a Christmas Day flight to Detroit. To combat this threatening problem and for the people’s security, the TSA has worked with two essential technologies to upgrade its passenger screening systems- the Millimeter-wave and the Backscatter X-ray.

Evolution of Solar Cells

With the non-renewable sources of nature diminishing and the global warming effect increasing, Solar energy is vital in the present times because the power demand in the world is a never-ending process. And the emergence of solar cells in the 19th century has signified the importance of solar energy today, in our lives. A solar cell is a device converting sunlight energy directly into electricity using the photovoltaic effect. The term “photovoltaic” is used since 1849, derived from Greek ‘phos’ meaning “light” and ‘voltaic’ meaning “electric” from the name of the Italian physicist Volta. Today, these solar cells or the photovoltaic cells are used to make solar panels, solar modules, or photovoltaic arrays.

Technologies used in “Avatar” Movie

Writer-director James Cameron is making another cinema history with the breathtaking new 3D technology in his latest sensation, “Avatar,” which has swept the world with more surprises giving a new dimension to the world of cinema. Cameron developed this new technology that could finally revolutionize film making by getting the 3D and the CGI to new heights while mixing the real footage and the motion-captured CGI in an immersive 3D technology. A brief review of the technologies used by the director that powered some of the most stunning effects of the movie is given below:
