6 Top Features of the Luggage Scales

Luggage scales are a useful piece of kit to have at home to avoid issues with paying excess baggage fees. Most of the airlines set different weight allowances so it can be difficult to get it right for the frequent travellers. They are easy to use and can include a variety of features to match the specific needs.

Let’s take a look at the key features worth having on the luggage scales:

Weight capacity

Weight capacity is a major feature to consider. This needs to easily reach the maximum limits set by the different airlines. Many of the luggage scales will accept a load up to about 110 pounds, which is more than enough. Additionally, the accuracy can vary with the different units. Most have an accuracy leeway of about by 0.1 pounds. This is likely to give enough accuracy for most unless very close to the airlines permitted limit.

Screen lock

The weight lock is a user-friendly feature that will ensure the total weight of the luggage is kept on the display screen for a certain period of time. This makes it a lot easier for a single person to use the scales without having to hold the luggage and read the display at the same time.

Type of Display

The weight can be displayed using analogue or LCD. The LCD units are easier to read if the screen is backlit. Many of the low-cost models are particularly difficult to read in bright light conditions. Also, the LCD units will use more battery life. The alternative option is those built with a traditional clock dial. They do not rely on extra battery power and are still very easy to read.

Compact size

The luggage scales are typically compact in size which means they can be taken on any journey. This will give the option to weigh the luggage again before the return leg of the journey to avoid going over the permitted limited after buying souvenirs for friends or family on the travels.

Battery indicator

Many of the feature rich units have a battery indicator to give a quick reminder of the available charge left in the battery. This is great for those that travel often and need to make sure it is always ready to use.

Automatic shut down

A useful feature to save battery life is automatic shut down. This is often seen on the luggage scales with an LCD display. Most units will switch off after 30 to 60 seconds of no activity.

Rado Watches – Watches for Every Occasion

Considering every taste while making watches :

Rado is a major Swiss watch brand that has been creating watches since 1917. But it was on 1957 that the brand started to make watches under the name Rado. Its takes inspiration from the tagline "if we can imagine it, we can make it", to make watches for all. They have been consistently crafting watches with brilliance, and can anticipate the prevailing trends. So they are successful in making timepieces that matches with the taste of every watch user.

Introducing ceramic in watch making :

Rado is the only brand to have used ceramic for the first time to construct watches. Later, they fused cermet and titanium with ceramic to break the usual method of making watches. Ceramic is hard substance that helps to make scratches scratchproof. Further on, they bought high tech plasma ceramic into the radar of crafting watches.

The distinguishing factor of Rado watches is that it never pauses in applying new and unique ideas to make watches. After launching ceramic built watches, Rado has also introduced ultra slim watches. It created a rage among the watch lovers. Its True Thinline collection combines the brand's slim watches.

Scintillating collections that makes you surprised :

With a gamut of versatile watch lines like Centrix, Ceramica, Coupole, Diamaster, Diastar, Esenza, Hyperchrome and others; Rado watches are the first choice for users of every taste.

Centrix :

This collection known for watches that has distinguishing structures and style. These two things are the major reasons for their gaining popularity. The dwindled, slim and malleable bracelet smoothly and sensibly holds the wrist. Its offers refined ease and finesse, as well as stubborn pleasure and poise. This collection enterprises of both gents and ladies watches that match all taste.

Centrix Gents:

Build with hard and determined ceramic, every Rado Centrix men's watch has boldness and tactility with them. Almost most of these watch have black dials. Black representations muscular strength. The steel built case models present a sizzling lustre that sparkles at the wrist of a fearless male watch user. Watches built with the mixture of gold and PVD stainless steel, or steel and rose gold PVD case have a flavor of charm as well as rock like sturdiness.

Switted with the round shaped black dials, some models have straps colored with the blending of rose gold and black or golden and black. Some pieces have grayish golden straps to produce a magnetic appeal. Shining stainless steel straps twinkle at the wrist of a watch user, while leather built straps of the watches add a mild flavor.

Other than the blackish dials, Centrix watches are also available with dials polished with multiple colors like brown, silver, gold and many more. Water resistance quality of these watches vary from 30 to 100 meters. This is an active function present in a Swiss watch. It is a property that helps to avert dangers occurred due to water and also assists observers to increase their performance level.

Centrix Ladies :

Parallel to the gents' watches, female watches of the Centrix line has similar designs and looks. With plain dials and well studded diamonds, every ladies watch increases the glamor value of a good looking and smart lady. Some additional colors like mother of pearl and champagne have been included to varnish the dial of these pieces. Women are fond of gold, so gold plated straps are used to bind the case of these watches. Date display counter is placed at the right side of the dial. It shows the current date and keeps you updated.

Both quartz and automatic movement is loaded with the ladies Centrix watches. Quartz and automatic movement maintains the preciseness of these pieces, but pieces with quartz movement needs a battery that must be replaced within a certain extent. Automatic movement included watches does not require battery, it charges with the natural oscillation of the wearer's hand.

Plethora of active features like tourbillon makes the watches very accurate. Luminous hand functions helps to glorify the wrist of a user, while the skeleton dial enables you to see both sides of a watch dial. Other regular features like analogue display, day date and date display is available with these attractive Centrix models.

Coupole :

The different factor factor of Coupole watches is that it has clock like small and medium sized dials. It helps in increasing fashionable attractive of the pieces. This collection has watches for men as women.

Coupole Gents:

Calm and composed, men's watches of this collection perfectly represent the solid attitude of a muscular male watch wearer. Its strong steel base makes the watches perform longer. All of these watches have circular dials polished with various colors like white, silver and others. Toughly gripped straps are built with many substances like stainless steel, leather and two tone. Leather straps presents thinness, two-tone strap produces a diversifying effect and the stainless steel strap helps the pieces to glorify the wrist of a watch user.

Diamonds have coated in some models. It lifts the dignity of a dignified watch user. Its water resistance property ranges within 30 to 50 meters. Function like date display is located at the right side of the dial. It exhibits the prevailing date.

Coupole Ladies:

Sophistication is at its best in these gorgeous and stylish ladies watches of Rado Coupole collection. Design of the watch straps are like chains. This is an example of the brand's application of new ideas. There is a conventional flavor in all the models of the line. Along with it, their looks are also impressive.

Hurricane Control, a Practical Solution

The NOAA (National Oceanographic and Atmospheric Association) experts have thrown “cold water” on hurricane control schemes. Including the schemes actually using cold water. This article will take a look at the “Proverbial Pipe Dream” of Hurricane Control and propose a practical solution. At present there a variety of various hurricane control proposals.

Hurricane control in the current context really means to weaken the hurricane force winds. The destructive damage a hurricane inflicts is proportional to the square of the wind speed. Hurricanes are windstorms in the Atlantic and Eastern Pacific. In the Western North Pacific and the Philippines the windstorms are called Typhoons. Cyclones are windstorms in the Indian and South Pacific Ocean. When the ocean temperature is about 80 degrees F (26 C) or higher a hurricane can occur. The hurricanes operate by drawing warm ocean air up through the eye of the hurricane. This is a convection process with hot air which is less dense rising. Current hurricane control methods try to disrupt this convection process.

First lets look at “cloud seeding”. Cloud seeding is done to increase precipitation by introducing small particles of various chemicals into the air from the ground or by air. These particles are introduced into the eyewall of the hurricane to disrupt the upward flow of moist air. Another method proposed is to cool the waters of the ocean where hurricanes are likely to develop with long vertical tubes. These wave actuated pumps would bring warm surface water to the bottom and force cool water up. Again this would disrupt the convection process. Giant sized fans have even been proposed to blow the hurricane back into the Atlantic ocean. Animated “cartoon like” procedures, even though well meaning, don’t work for the following reasons. The enormous size and power of a hurricane make these type of schemes unlikely to work. Information from the NOAA’s Atlantic Oceanographic and Meterological Laboratory gives some insight into the power of a hurricane.

An example is Hurricane Andrew which hit South Florida in 1992. The area of destruction was 20 miles wide. The heat energy in this hurricane eye was “5000 times” the heat and electrical power generation of the Turkey Point nuclear power plant over which the eye past. The kinetic energy of the wind at any instant was comparable to that released by a nuclear warhead. A realistic hurricane control system would have to be ready to go into operation within 1 day. Only about 10% of the tropical systems that form develop into hurricanes. Trying to attack them early would be a wasted effort. The hurricane control system should be able to be put into operation when the hurricane is at least a category 1 and is heading toward a populated area.

I am proposing a modification of a fairly popular and tested method of decreasing a hurricanes destructive power. The method I am referring to is Space Solar Power. Solar panels in earth orbit can convert solar energy into a microwave beam. This microwave beam can then be aimed at a hurricane eyewall to heat it and interfere with the hurricanes convection process. A government project called HAARP (High Frequency Active Auroral Research Program) has demonstrated that microwave energy can be directed at the ionosphere and heat it.

Space solar power projects to control hurricanes involve launching a satellite into orbit. Until this method is fully proven. A more economical approach would be to save the cost of the launch and the satellite and mount the microwave equipment on a ship. The microwave ionospheric heaters could be powered by off the shelf electric car batteries and the ship could re-charge when in port. This ship could be under the supervision of a state government and called into service by the governor of a potentially affected state. The ship could stay back from the hurricane eyewall and aim its microwave antennas at a 45 degree or lesser angle. This ship could be called into action within 4 hours notice. If this plan works another ship can be built and sold to another state or foreign country for a profit.

Current weather trends make this plan more likely to be effective. An NOAA research study has found that Global Warming has made hurricanes worldwide move slower and stay over of populated areas longer. There by causing more damage and increasing the chances for flooding in the area the hurricane is hovering over. Some thing should be done to at least try to minimize the impact of hurricanes.

DIY – Solar Battery Charger

Hi Everyone, I am back again with this new video tutorial.
In this tutorial, I am going to show you how to charge a Lithium 18650 Cell using TP4056 chip utilizing the solar energy or simply the SUN.

Wouldn’t it be really cool if you can charge your mobile phone’s battery using the sun instead of a USB charger? You can also use this project as a DIY portable power bank.

The total cost of this project excluding the battery is just under $5. The battery will add up another $4 to $5 bucks. So the total cost of the project is somewhat around $10.

Three Emerging Technologies that Will Change the World

I was speaking with a friend the other night about his great grandfather. His great grandfather was born in 1875. He lived until 1965. Can you imagine the technology that this man saw come online? Let me name a few: the typewriter, the electric dental drill, the telephone, the phonograph, the incandescent light bulb, the hearing aid, the electric fan, the dishwasher, the escalator, the airplane, the Model T automobile, the air conditioner, the defibrillator, the atomic bomb, the electric guitar, the nuclear submarine, nylon, the polio vaccine, and the laser. He died right when the first minicomputer was coming to fruition. All of that in the span of his lifetime. Which leads me to the topic of this article. Technology has completely changed the way we live. And technological advances have accelerated at unbelievable speeds. Technology is converging in ways no one could have foreseen. I want to highlight some of the most interesting technologies out there. These are technologies that will change the world, for good and bad.

Nano Technology

Probably the most interesting and frightening of the emerging technologies is nano technology. Nano technology is a cross disciplinary field that deals with building and synthesizing materials at scales of 100nm or less. Nano technology usually works in one of two ways. It either pulls smaller parts together to build or it breaks bigger parts down. The parts are then used to form smaller, new materials. But why is nano technology so important?

Nano technology is important because it will have massive effects across every area of life. As I write this, researchers are working on a nano particle to target cancer cells in lungs. In 2004, Rice University tested gold nano particle cancer treatment. In this treatment, these 150 nanometer gold particles were injected into the blood stream of cancerous mice. Gold particles at this size pass into tumors, but not healthy tissue. The researchers then passed infrared through the mice. The tumorous cells absorbed the infrared, heated up, and were destroyed. They are also working on quantum dots that allow doctors to easily identify multiple diseases quickly and accurately. But the uses don’t stop there. Nanotechnology will drive down the scale of electronics. This will lead incredibly small devices. The applications are limitless. And you can bet that the military will be clamoring for nano technology. The military is looking to have numerous nanotechnologies online by the year 2015. Such advances include performance enhancing nanotechnology that aids bodily functions. These will include response times, oxygen use, and heightened senses. But nanotechnology can also be used for reconnaissance and combat. Nanobots could scout areas without being seen. They could also enter into enemies for espionage. They could kill targets from within the host’s body. The possibilities are frightening.

Alternative Energy & Fuels

When gas prices skyrocketed this past year, many people suddenly took an interest in alternative energy and fuels. And because demand rose, companies suddenly found themselves forced to take interest. Most of the common arguments for alternative energy and fuels center around issues of pollution, cost, dependence, and jobs.

What most people don’t realize is that alternative energy and fuels always have environmental effects. This can be in the form of heat generation, air pollutants, waste by-products, land usage, extraction, etc. Instead, we have to talk about pros and cons around each type of energy and fuel. There is no silver bullet. Costs, dependence, and jobs also vary depending on the energy type.

There are a host of alternative energies being tested. Wind powered energy plants are already in place in many parts of the world. Solar energy production has taken huge steps forward with the help of nano technology. One such company is Nanosolar. Nanosolar is producing solar cells that are 100 times thinner than conventional cells. Not only are the cells cheaper to produce, but they also convert the solar energy much more efficiently. Ocean thermal energy conversion (OTEC) uses the temperature differences in the ocean layers to produce energy. And OTEC can utilize this colder water (36 degree F cooler) in other things like on shore agriculture and refrigeration. And the list goes on.

Massive interest was generated in alternative fuels this past year when gas prices hit record levels. New developments in battery technology could help. One such development is Millennium Cell’s hydrogen battery technology. This technology differs greatly from traditional rechargeable batteries in that it’s instantly rechargeable. It also has a much great efficiency for energy conversion, so it is much smaller and lighter. There is also greater reuse efficiency since you don’t need to replace the entire battery. You only need to replace the energy module. Developments are continuing in biodiesel, electric, hydrogen, methanol, etc. I think there could be some serious future synergy between nano technology and alternative energy.


This is my name for the incorporation of technology into the body. The dermal display is a great indication of things to come. Though I have yet to find a working demo version of this concept, I have no doubt that it will become a reality. The display would be driven by millions of nanobots. These nanobots would display light when touched. This would print a display onto your hand, or wherever the nanobot display would be housed. And this is where it gets really interesting. The display nanobots would be connected to millions of other fixed and mobile nanobots throughout the patient’s body. This would give instant readings on hundreds of vital statistics. Again, nanotechnology plays a strong role here.

The bionics revolution is already underway. There have been four major cases of robotic limbs recently, the latest being a woman. The robotic limbs take advantage of the functional nerve endings in the limb stump. These nerve endings are used to actuate the robotic limb and to provide feedback to the brain. More money is being poured into robotic limbs every year.

“Functional bionetics” are implants that enhance our lives. And you may be surprised to know that people are actively doing this as I write. People are inserting tiny electronics in their bodies that will unlock their front doors and their cars. The same technology is being used to unlock computers. But it doesn’t stop there. There is talk of implanting devices that will carry health information. You could be carted into a hospital totally unconscious and they would be able to access all of your past medical history. Most of this is done through RFID technology.

“Bionetic networks” will be networks of connected bionetic devices. This would allow people to share sensation, feelings, and communication. If this sounds completely fictional, I invite you to consider the work of Kevin Warwick, Professor of Cybernetics at the University of Reading, England. He has implanted an extra-sensory device that interfaces with one put in his wife. They were implanted in their arms. The first experiments are aimed at exchanging sensory inputs, like pain. The hope is to extend that to other, more complicated neurological processes like thoughts and emotion. Obviously, that would drastically change relationships and indeed the world. Forget about your teens text messaging, maybe they will be brain linking in the future. Now that’s really scary!

What will we be able to say came online in our lifetimes? I’m sure we could already list a lot of important technologies. But keep your eyes out for these emerging technologies. They are set to change the rules of our world. These technologies will upset economies, change military tactics, empower people, and be used to control others. Keep an eye on them.
