Sometimes it is better to see one time than try to imagine things – especially in electronics. When trying to design something in electronics, probably it is a best way to take some sort of circuit simulator and make a simple model of it to see how it works before putting in to real worlds design. If you want to make quite 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 simple basics how circuits work, how current flows in one or another situation. For this you should try this Java based circuit simulator.

IT can be run directly on the web page or downloaded and started locally. It takes very little space, but has many useful features including:

• Lots of premade circuits that are ready to run;
• Customizable animated simulation where you can select current speed, simulation speed or other specific parameters;
• Scope views;
• Ability to build your own circuits.

Of course it can’t beat the real simulators, but can serve as quick checklist on how things work. This java based circuit simulator seems to be updated constantly with new features and units. Just give a try and see how well you know basic electronics.

The designing of wearable electronics involves the use of some sensing devices, connectivity and some other computerized devices that are well designed in the clothing materials that people are wearing in the recent past days and the days to come. They are well designed that they do not cause any discomfort in you as they are like any other clothing material. They are lightweight, more fashionable, and above all they have no difference at all from the other clothes known to many.

Although most of these wearable electronics are made by the machines and other computing devices, you will find out that most of them are nowadays sewn as electronic gadgets like sensors are to be carefully sewn to these clothes. Other components like the circuits are well designed to the wearable electronic using the thread and the quality fiber. They are made to be wearable so that others can never discover that whatever you are putting on is meant to trigger some sense to you in case of any emergency. Read the rest of this entry »

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 also as a political factor that can generate the much needed votes for any major election – consider the election of Barrack Obama, 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 loose in terms of money if they don’t device simple time tested ways to save energy. It is for such that the simple ways to save energy is given because as earlier said they have more to loose.

Monitor the meter

They say that it is important to know your enemy before you set out to fight him; the same applies for the energy input devices in your home or business. 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 therefore how much can be saved per month. Moreover, it will be important to do a walking around to ascertain the important places and points where energy saving can be done. Read the rest of this entry »

Domestic robots or home helpers like they are referred to can be used for house hold chores like vacuum cleaning and serving guests. Science inventions and technological breakthroughs have enabled the use and help of these artificial human beings be greatly received and appreciate for the easy at which they are making be. Some people are even demanding for much more improved robots that can actually think and do things just like 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 in near future than it has never been seen. Right now the most commonly used robots home helpers are the vacuum cleaners. The vacuum cleaners use air pump to create a semi or partial vacuum to be able to suck up dust and dirt from the floors. The collected dirt and dust are also stored in the dustbag 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 just control the vacuum cleaner as it collects all the dust from the floors or tables and leaving them spotlessly clean

The other home helpers’ robots are the entertainment robots for example the HERO or AIBO. Just like the name suggest they are made with a single subjective role of creating pleasure and ensuring the owner is entertained just lie intended. This might be more complicated because there is no existing machine that can actually do things like a human being so it will just offer the programmed service without attaching emotions to it or maybe offering other cropping demands like a human being can. We use hi fi machines and other machines that have used the robotics technologies and it is now a trend that in most cultures and entertainment areas most robotics technologies are applied

The robots home helpers are used to perform jobs and task that human feel are dangerous or dehumanizing for instance washing of sewerage drainage systems or swimming pools. These kinds of jobs can be dangerous in nature especially the swimming pool cleaning can be fatal if the cleaner is not a good swimmer and he or she slips in the water.  The sewage drainage job is dehumanizing and a machine that is programmed to do that can carry out the duty very well and effectively than a human being who might do it hastily and shoddily.

Most parents are now working and staying with their kids during the day can prove a little bit demanding yet they have  job to do, so they get help of baby sitting robots who are programmed to sweet talk the kid and even sing to them, incase they are agitated and are crying. This kind of job reduces the kind of a work load a parent has at the end of day. The robots are great helpers and with time and more inventions superior and more complex one which can carryout a more demanding duty with human touch in it will be developed for human use at home and in the offices

Nobody can doubt the effort of scientists 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 3^rd electrode, normally referred to as gate electrode, the manufacture of these transistors takes time, money and energy.

Determination by scientists and researchers so far has bore fruit; they have made a breakthrough with the first molecular transistors being made. This brand of transistor 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. Read the rest of this entry »

Augmented reality also referred to as the AR is a concept that is used to view the corporal world either directly or indirectly. When viewing the world this way, the essentials are practically computer created imaginary things thus creating diverse certainty. The augmentation of the world is viewed in the actual time and in semantic situation with ecological basics like soccer scores on television in mind. AR (Augmented reality) works hand in hand with technology to make the physical world networked and technologically working. Among the augmented realities that are incorporated with technology includes computer image and entity identification. Any non-natural detail about the surrounding and the images are capable of being stored and thereafter recovered as information concerning the real world.

Augmented reality has continued to get impetus as the years and technology advances. The most recent use of the augmented reality was used in the testing of the United States Marine Corps on a resistant steeple. The system that was used was called ARMAR (Augmented Reality for Maintenance and Repair) was designed and made at the Columbia University’s Graphics and user Interface laboratory. A mobile phone was used to view and manage the graphics in conjunction with a head built display that assists its users in repairing it. The augmented reality in industry was designed to use 3D motion picture that assisted in the exhibition of the appropriate gadgets and methods in a variety of repairs. Up to date, this system is still being used by the military personnel and has proven to be very beneficial. Read the rest of this entry »

The nuclear power industry along with the reactor technology has been constantly 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 fission nuclear reactors are mostly 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 the speed of neutrons. Thermal reactors are the most affordable and common as they use the natural and raw uranium; and the neutrons are decelerated from their natural speed when emitted from the broken atomic nuclei, and uses a moderating material in the process. The Fast reactors are very expensive that require more enriched fuel. Read the rest of this entry »

Imagining one’s life without electricity is something incomprehensible but there are times when one is forced to face this kind of situation in his life often and moreover there are really some few places in the world which still do not have electricity! We could also not forget the fact that the world is marching towards a severe energy crisis and that the energy resources which we use so proudly today are not inexhaustible. With the global warming effect increasing and with the increased consumption of these energy resources, all the natural resources are diminishing at an alarming rate and their basic finite nature makes the human minds think more on the survival aspects, in case we have to face it sooner than later.

What is required at this point of time is the need for awareness of the importance of energy (electricity, oil, gas, or anything) in our lives and take measuring steps to minimize our use of that finite supply. There are a number of alternative pragmatic power solutions available to us these days which are very cost-effective and surely contribute to a better future for the world if there comes a point when we have to live without electricity.

The new full body security scanners might become a popular alternative to body searches with the increased alleged terror threats over the globe. The full body scanning system has taken the world with a surprise in the past recent months. It is the most advanced system of the whole-body imaging technology that involves scanning of 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 normal metal detectors could not find. The process to install these scanners at more airports in several of the 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 security of the people, the TSA has worked with two basic technologies to upgrade its passenger screening systems- the Millimeter-wave and the Backscatter X-ray.

With the non-renewable sources of nature diminishing and the global warming effect increasing, Solar energy is vital in the present times considering the fact that the power demand in the world is a never ending process. And the emergence of the solar cells in the 19^th century has signified the importance of solar energy today, in our lives.

A solar cell is a device converting the sunlight energy directly into electricity with the use of 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. These solar cells or the photovoltaic cells today are used to make solar panels, solar modules, or photovoltaic arrays. Read the rest of this entry »
