Invisibility Technologies

Invisibility is often used in movies to express a magical feeling in the minds of the viewers. The word ‘invisible’ itself is magical and needs a lot of connotation. When something is invisible, it creates a magical effect and a questioning mind, and this makes the viewers probe into the field of invisibility technology. Really is there something called invisibility cloaking? Fictional movies have used invisibility cloaking to make something disappear for some time, and when the cloak is removed, the thing or the person appears again. In 2008, a physicist named Michio Kaku prophesied that a feasible invisibility device like the ones used in Star Trek could emerge from research laboratories. He also quoted David Smith of the Duke University who had used meta-material to bend light around an object. He also quoted that German scientists have found that a meta-material can make the red light around the object.

Fuel Cell Technology: Advantages and Disadvantages

In this age of technology, there is a development every minute in almost all the fields in one regard or the other. Such a significant result in a lot of alternate energy is the Fuel cell. A fuel cell, in simple terms, is an electrochemical energy generating device. It has been one of the most fascinating and interesting aspects of today’s world’s technology. Many things are yet to be developed in this field, and there are a huge scope and application for these Fuel Cells. These fuel cells are being under research by many people all around the world. Construction and Working There are many different types of fuel cells. But the basic construction and working of a fuel cell are the same, and the concept behind it is also the same. The Fuel cell works on the principle that energy is produced when some chemical reaction occurs. If this energy can be tapped, it can be converted into practical means. In a conventional fuel cell, the reaction occurs between hydrogen and oxygen, and water is formed. This is the primary chemical reaction that happens, and energy produced by this is tapped through proper channels and used for several applications.…

Automated Guided Vehicles

Automated Guided Vehicles help transport the raw materials, semi-finished products, and finished products within a workplace. Initially, in any industry or a workplace, the materials are transported from one work station to another work station manually or by using a vehicle that the human operates. Because of the manual interaction, the time taken for transporting the materials is high, and because of the increased time, the production rate of an industry comes down. To increase the production rate and utilize the resources like labor, machine efficiently in an industry, Automated Guided Vehicles have been brought into existence. The Automated Guided Vehicles cannot be installed in the workplace as such. It needs a lot of planning and design. This is because the Automated Guided Vehicles installation is costlier, and once installed, it would be difficult to change them. Thus, before installing the Automated Guided Vehicles, the Automated Guided Vehicles’ installation and movement region should be pre-determined. The layout of the company plays a vital role in the Automated Guided Vehicles system installation. Automated Guided Vehicles’ primary purpose is to reduce the travel time of the raw material or the workpiece. So the shortest route between the workstations has to be identified,…

Topobo – robot with kinetic memory

Robot toys are trendy among children these days. Especially DIY robot kits are getting more popular as these kits stimulate imagination and creativity. Topobo kit is becoming a most playful robot kit with kinetic memory where the assembled robot can memorize its motion and play it back. It is possible to teach robot various motions like animal walk, dance by simply guiding it. Three researchers of MIT Media Lab developed Topobo. This is not a new toy, but since 2003 it was used for various exhibits, and only a few lucky could try this toy. Now, this kit is widely accessible.

Unveil the Secrets of Atanua!

You’re one of the home hobbyist and you love to spend most of the time doing the electronic projects in the weekend? Then, you must know how frustrated it will be, if the project that you’ve done cannot function properly according to your need? Well, cheer up! All you need here is an assistant that can help you off. Then, this Atanua can be your little helper here. Here is a little extra fact for the word “Atanua”. According to the Polynesian, Atanua is the goddess of the dawn and wife of Atea. Atuanua is the one that created the seas after her having a miscarriage and filling the oceans with her amniotic fluid! (Well, it’s only one of the Polynesian myths.) For your information, Atanua is a real-time logic simulator, where it was designed to help you to learn the basic Boolean logic and electronics. It uses OpenGL hardware-accelerated rendering and a custom UI. This way, it can help us detect the fast workflow and a shallow learning curve, thus concentrating on learning the subject quickly. Basically, the Atanua UI consists of three main parts, which as: The component list The work area Buttons for useful functions, such as…

The Multipurpose Controllable Power Outlet

For all the home hobbyists, you knew that dealing with microcontrollers is a fun thing. Once you have been hooked with it, there was no turning back. Do you know that a microcontroller’s GPIO (General-purpose input/output) pins cannot handle higher power requirements? An LED was easy enough, but how about the large power items such as light bulbs, toaster ovens or blenders that required more circuitry? In this case, a relay is wanted in this situation. However, building a 5V controllable power outlet can be handy for many applications; thus a relay is a perfect choice for this project! For your information, a relay is a large mechanical switch, where the switch is toggled on or off by energizing a coil constantly. By applying the relay in the project, it will ensure your safety. Let’s take an example. If you have 120VAC running through the paddles, you don’t have to worry that 120VAC will sneak back into and vaporise your microcontroller connected to the coil, as the paddles are capable of carrying substantial currents! Furthermore, you can use the relay to control a DC motor or an AC lamp if you want to.

Surgical robots-for better surgery

Surgeons in Australia are excited over new surgical robots they are with to work surgical operations on patients. These new robots tolerate surgeons to work operations using enhanced precision to reduce postoperative complications and actually require fewer poles during the surgical method. Here’s how it works: using the surgical robot’s help, surgeons’ diffident behavior two automatic arms inserted into the tolerant through small incisions. A high-resolution 3-D telescope accompanies the mechanical component so that the doctor can see what’s gratis on. Seated at a console, the doctor can then work composite travels such as making incisions, manipulating tissues, or even suturing tissues.

The Stirling cycle – technology beyond expectation

The key code of a Stirling engine is that a downright calculate of gas is sealed within the machine. The Stirling cycle involves a cycle of check that mutation the hassle of the gas within the engine, causing it to do work. There are numerous properties of gasses that are risky to the venture of Stirling engines: If you have a rigid amount of gas in a rigid level of celestial and hoist the gas’s temperature, the hassle will improve. If you have a rigid amount of gas and compress it (decrease the level of its space), the gas temperature will improve. Let’s go through the piece part of the Stirling chain while looking at a simplified Stirling engine. One cylinder is heated by an outdoor heat bound (such as a fire), and the other is cooled by an outdoor cooling bound. The two cylinders’ gas chambers are allied, and the pistons are joined to apiece other mechanically by a linkage that determines how they will move about one another. You can add heat to the gas inside the heated cylinder (left), making it a bit hard. It compels the piston to move a little down. This is the part…

Happy 40th Anniversary to the First Computer Mouse!

A mouse (Not the pesky rodent!) is a pointing device, where it functions by detecting two-dimensional motion relative to its supporting surface. To be more precise, a mouse consists of an object that holds under one of the user’s hands, with one or more buttons. As you can see, the contemporary computer mouse has a wheel that allows the user to perform various system-dependent operations. Do you know that inventor Douglas Engelbart was creating the first computer mouse on Dec 9, 1968? After a glorious 40th anniversary years, Douglas said, “Although there’s been an explosion of technology in the past 4 decades, it hasn’t reached the level of potential he envisioned in the early 1960s yet!”
