As the name itself implies, cable testers serve to determine the condition of cables so that the user knows whether they are working properly. These pieces of testing equipment are generally handheld and the testing begins with a press of a few buttons, once the device is attached to the cable that requires inspection. It takes a minute or so and then the device provides feedback regarding the condition.

If there’s something that holds the great power on Earth, it’s got to be emotions (the secret of a lifetime revealed: yes, we men have emotions too). Just think about it, what makes certain people present in our lives be so dear and near to our hearts – emotions. I’m not afraid to say emotions make the world go round, love can move mountains, or at the very least relocate you to far off places for the person you love. To those of you hoping to uncover a love story further in the post, I’m sorry to disappoint you, but this is another kind of a love story I have in mind.

Here’s an idea if you’re up for adventures: make your wish for travelling and experiencing new things come true by joining an expedition! If you live near a University or an organization that does scientific research and exploration in remote places, pay them a visit and ask how can you join and contribute. Just please, make sure it’s something you’re passionate about so you don’t turn out to be a complete waste of time and resources to the organization just so you can fill in some of your free time.

In a world of technology, we’re dependent on our electronics every moment of every day. As bad as it might sound, it also brings about many prospects job wise. The never fading trend of social networking has made it possible for everyone, enthusiasts and professionals alike, to show off their photography skills and share their work with the world. Some succeed, some don’t, but it’s not to say you should give up on your dream altogether. Being a successful photographer takes some planning, kind of like when developing any business idea, as well as not giving up when the first obstacle appears.

It’s certain there’s no scarcity of photographers, so how does one start off? The answer is simple, all it takes is doing the right investments. When you invest, you know you’ve made the steps in the right direction and can be prepared to expect a positive outcome. Of course, it’s logical you’d have to invest in the proper equipment, not just thinking of the camera but also all the additional requisites, such as different lenses, tripod, filters, cleaning kit, quality batteries and straps. If your fund doesn’t exactly allow such expenditure for the time being, it’s advisable to rent pieces you’d like to try out and experiment with and invest in large format photo printer instead and give large format printing a chance.

Large format printing can make a world of difference and help you stand out from the crowd as it’s an investment that can work out in the long run. Starting out with getting your large prints out in the world could land you an exhibition, have your works of art hanging in people’s homes and even get you some extra money by printing out photographs for customers. It’s also going to help you with seeing where you can upgrade your skills as you get to edit your photographs better when they’re in large formats, since the resolution is most visible then, and fix problems without the use of filter programs but with using angles, focus, and photography rules such as the one of thirds.

Another step you should take, that’s also a kind of investment, is travelling. The more travelling experience you gather up, the more you get yourself out there in the world and increase your chances of meeting people along the way who can help with your success and promote your name. Besides, who can complain being out and about discovering more of the world and the diversity of cultures; you’d notice the changes in your photographs as you get more travelling wisdom. Invest in yourself, and success would be guaranteed.

If you are looking to buy a long range flashlight, what you need is a throw flashlight. Despite the name, you don’t actually throw the flashlight itself. In fact, I would strongly recommend against doing that. It doesn’t work like a boomerang, a shuriken, a chakram, or any other throwing weapon. The “throw” part refers to the light beam. Basically, the two terms that are always used to describe the beam pattern which the flashlight gives off are flood and throw.

With a flood flashlight, the beam isn’t focused, but it lights up the whole area around the flashlight and they often have more output than throw flashlights. A standard light bulb in your home is an extreme example of a flood flashlight. It lights up the whole room without any specific direction.

A throw flashlight, on the other hand, is able to shoot a focused beam at very large distances without necessarily lighting up the area around the flashlight. An extreme version of that would be a spotlight. The most common way these flashlights are created is by using a parabolic reflector with the LED perfectly positioned in the focus so that all of the light that hits the reflector travels parallel to the same direction where the flashlight is pointing. Another way to do that is with the help of lenses and TIR optics.

When it comes to long throw LED flashlights, Olight are the true masters and one of their best models is the Olight SR52 UT. The SR52 Ultra Throw Intimidator is a next generation flashlight with more power in a small body and it really lives up to its name. Weighing at 405g, the Olight SR52 UT has a maximum output of 1100 lumens and can reach a distance up to an amazing 800 meters. This is all thanks to the latest Cree XP-L HI LED and the quality focus system and the ultra clear tempered glass lens with an anti-reflective coating.

One of the most notable differences between this and the previous model is that it has no dome which results in a more focused beam. It has a built-in charging USB port for its 18650 rechargeable lithium ion batteries and an indicator that will let you know when the batteries are full or running low. It has three different settings, plus a strobe mode and can run up to 40 hours at the lowest setting. It comes in a neat plastic box and a holster. You will also get a micro USB cable, a car adapter, two spare O-Rings, a user manual and a five year warranty. This flashlight is perfect for search and rescue operations, law enforcement and outdoor use in general.

If you just got out of film college and want to get into the production industry but don’t have the necessary funds yet to buy an expensive quality camera and all the equipment that you need for it, there’s no need to worry, there is a simple, more affordable solution – renting camera equipment. Even though this is a short term solution, since renting camera equipment frequently will eventually end up costing you more than buying an actual camera, it’s a good way to start making some serious money.

Most reputable shops and online stores will rent camera equipment at an affordable price for a couple of days or weeks, so there is no need to worry if you were hired as a photographer to a wedding and you don’t have a quality camera at your disposal. Or, if you just want a quality back-up camera in case things go wrong, because people are paying you good money to do some amazing shots, and you can’t let them down if you want to uphold a good reputation for yourself as a photographer. Here are some of the benefits that come along with renting camera equipment:

  • Test the Gear – When considering to purchase an expensive camera, lens, external flashes or any other accessories, you should test them beforehand. Most stores will let you equip some lens on the camera to try them out. Furthermore, you can try two or more different items on the spot to see which one will fit you better, instead of reading online reviews or relying on the advice of the salesperson.
  • Extra Gear – Most rentals will allow you to take more camera gear if you need it for a shorter period of time. Some will even go as far as giving you a backup camera so you can equip different lenses to save time on changing lenses constantly. This will also allow you to use some accessories that you otherwise wouldn’t, which might be essential at this point.
  • Budget Friendly – You will have access to camera gear out of your budget – amazing cameras, long and specialty lenses. In other words, you will be able to use equipment way above your budget, without breaking your bank. However, you need to weigh in the factors. For example, if you intend to rent camera equipment on many occasions, you should consider buying it, as renting it far too many times will eventually surpass its price.

It’s obvious that every electrical device needs power for it’s components to operate properly. The device responsible for providing that power is the power supply. There are two types of power supply designs: linear power supplies and switch mode power supplies. A switch mode power supply is a converter that transmits power from a source (e.g.a battery or the electrical power grid) to a load (e.g. a personal computer) with ideally zero loss. Its main function is to provide reliable output voltage often on many different levels than the input voltage. The quality of your power supply is essential, it’s often undervalued and it is one of the most common components in devices that causes failure.

The Basics of Switch Mode Power Supply

There are multiple things to take into consideration when purchasing a switch mode power supply.
First, you need to determine the power that you need for your device to run smoothly. Measure the amount of power that your device will use. Always look ahead and plan into the future. Make sure the power supply is above the requirements of your device, as if you intend to upgrade your device, additional power will be necessary for it to run properly.

Research what type of connector you need. Different devices require different connectors. Newer power supplies will provide you 20-pin and 24-pin connectors, this is very important when it comes to connecting motherboards, in particular. For CPU connection, 4-pin and 8-pin connectors are the most commonly used ones. An 8-pin connector will provide more current to the CPU.

Durability is very important when looking to buy a new power supply. Keep in mind that an older power supplier won’t provide the same amount of energy as it did when it was first purchased. A switch mode power supply works with a rather high efficiency, meaning the series regulator is either on or off. Consequently, very little energy is converted to heat and therefore, high levels of efficiency are achieved. This also adds to the compactness of the power supplier, meaning, it is compatible with a wide range of devices.

There are also a few drawbacks of using a switch mode power supply. The most major ones are: noise and ripple coming from transient spikes that occur from the current switching action. This can become very problematic if not properly filtered. External components that come with the power supply are also an issue that adds to the cost and the space required.

Buying a digital camera can be daunting, especially as technology now offers us a great deal of brands and models. The key to finding the best camera is knowing what to look for. In the digital cameras market, it can be easy to get lost with camera-related words like megapixels, USB, compactFlash, etc. To avoid getting headaches and find what you want with ease, follow our informative step-by-step guide to make a wise decision.

1. Determine Your Needs

A mistake made by many is buying a digital camera that is beyond actual needs. This is why it is advisable to ask yourself some question before you go shopping.

  • What do you need the camera for and which type of photos will you be taking? (landscapes, sports, portraits, macro).
  • Which are the conditions you mostly will be photographing in? (low light, bright light, indoors, outdoors)
  • How much experience do you have with cameras?
  • What kind of features are you looking for? (image stabilization. Long zoom, large LCD display?
  • Most importantly – what is your budget?

When you have the answers, you are set for searching through camera stores online or visiting a local camera store. This will put you in a much better position to make a decision on which camera is best for your needs.

2. Look Beyond Megapixels

While a few years ago the number of megapixels was actually pretty important, nowadays you can find all kinds of cameras with a considerable number of pixels, including simplest types. With so much technology available, megapixels aren’t so important anymore. Sometimes, more of them can actually be a disadvantage as they take more space on computer and memory cards. Still, it all depends on one main factor that should be considered when it comes to megapixels – will be printing your shots? If so, decide their size – for a normal picture size, anything over 4 megapixels will be enough. But if what you want is to print huge pictures, then you should be prepared to spend a great amount of money on a high-end model with more megapixels.

3. DSLR or Point and Shot – Which One to Choose?

Although digital DSLR cameras are becoming more affordable, they are not for everyone. On the one hand, they are often heavier, bigger, harder to maintain, and can be a lot more complicated to use than point and shoot cameras. Point and Shot cameras, on the other hand, are simple to use, and are slim and light, which allows you to simply slip them in a pocket as you go to a party, and not have extra weight when you travel. While some people see them as an inferior camera, depending on the type of photography you will be doing, your budget, and the features you want, it can be the appropriate choice for you.

4. Optical Zooms Are a Must

When looking at different camera models at camera stores online, you will see the zoom presented in two ways – optical zoom and digital zoom. It is highly recommended that you consider the optical zoom when deciding which camera to choose. Although digital zoom enlarges the pixels in your shot and makes the subject look bigger, it also makes it look more pixelated.

5. Read Reviews

Before purchasing a digital camera take some time to do a little research. Make sure you carefully read through all the product info when you find a reliable store. That will help you narrow down your choices. This is why buying online seems more efficient because when you pay a visit to a store you might be susceptible to the advice of the helpful sales person who may or may not know much about cameras or may have sales incentives for the camera they are recommending.

As much as night hunting may be hard and demanding, it’s fun and exciting. Yes, it requires paying a little more attention but when you catch your pray in the middle of that eternal blackness, the feeling of self-pride is just priceless. It’s the 21st century and people no longer hunt with spears and by hunch, they use hunting guns and torches to make this fun experience a less demanding task. So, the thing you should start with in order to have your fun hunting experience is to look for a proper hunting gun and strong hunting led lights.

There are many reasons why you should choose hunting led lights and here are some of the most important ones:

  • LED lights are very strong and powerful;
  • they give an amazing light output and constant brightness;
  • reliable durability;
  • offer a high degree of functionality in a wide range of temperatures.

Hunting flashlights are your second best friend when you head on a hunting trip (besides the good hunting gun and good preparation with munition and other hunting gear, of course). The flashlight lightens your immediate surrounding environment, the direct aim and a larger territory, especially if you’re in the woods. The good thing beside providing you with an increased visibility is the fact that the strength of the LED hunting light blinds the prey, it confuses it and makes it disoriented so it becomes a really easy target.

Another good thing about hunting led lights is that they’re perfectly positioned on the gun; they’re attached under the barrel and from that position they don’t create any problems from ergonomics point of view. Most models have a very compact size and design, so that’s another advantage. And finally, hunting flashlights are easy to install and the process itself takes very little time, so they don’t hide any visible objects, nor they impede aiming. When you choose your hunting flashlights, pay attention to the following features.

  • Strobe – strobe means that your flashlight can blink with a high frequency. This beneficial innovation delivers a few more advantages like confusing the animal, temporarily blinding it, provoking agitation, influencing its mental condition as well as inducing fear.
  • An SOS signal – this means so much in moments of high danger. In most flashlights it works up to 4 hours.
  • Firefly – as a feature this one is mainly used in extreme situations of military needs, but that doesn’t mean it won’t serve you while hunting as well. It’s a micromode based on microcurrents and it’s very convenient because it lasts for about 120 days due to its very low energy consumption.
