Most people use a laptop on a daily basis. Whether you have a home office and use it mostly for work or merely for entertainment, there is no denying that laptops are one of the most convenient pieces of technology to use. However, they can affect your sitting habits and have a bad effect on your posture overall. Their design makes them very practical, but on the other hand, they are impossible to use in an optimal position. Taking into account that their screen is connected to the keyboard, it’s impossible to type with optimal posture which is typically defined as holding keyboards at about elbow height and screens at about eye-height. However, laptops force you to choose – position them so you are able to type comfortably and you will later suffer from hunching over the screen which is too low OR you can hold your laptop so that you look the screen in the eye but type with contorted arms and wrists. It’s a tough decision that doesn’t really have a wrong or a right answer
You just spent almost $2000 for a MacBook Pro, and if you want to make sure it is well protected so that it stays in proper shape, the first thing you need to do once you get it in your hands is to buy a case for it. You’d be surprised how many people fail to realize that having a case for their MacBook, phone or any other device can significantly prolong its lifespan and make it look more stylish (although that’s a secondary benefit to protecting it from impact, scratches and everything else). But with so many different MacBook Pro cases available online, how do you decide which one is the best? Well, believe it or not, in the world of case manufacturing – the brand is the only factor you can rely on. Here are some of the most popular brands to be on the lookout for when choosing a MacBook Pro case.
Stepper motors, also known as stepper drivers, are commonly utilized parts in the robotics industry. If you’ve ever handled a precision machine or a 3D printer, you’ve probably used a stepper driver to some extent. They allow for precise and controlled movement and learning the basics and how to properly use them is always a good idea if you’re in need of them. That being said, let’s elaborate on the benefits of using a 3D printer stepper driver.
Stepper motors promote precision control. They ensure 100% precision when 3D printing in a controlled environment, so that you can rest assured your print will come out correct. Furthermore, a 3D printer stepper driver promotes speed control. You can easily reduce or accelerate the speed of the print at any given point, in a controlled manner. Additionally, stepper drivers can remain fixed in a position.
When buying a stepper motor, there are a couple of things you need to consider in order to make the right purchase for your 3D printer. First and foremost, consider the number of steps per revolution. Stepper motors work similar to analogue clocks, so they have a limited amount of positions. However, there are various different models that have a different number of steps. The more steps the stepper has, the better resolution you can get. Secondly, consider the angle per step, which is quite different from the number of turns per revolution. In 3D printing, 200 steps per turn equal to 1.8 degrees per step.
Then, you have to consider the size of the stepper. When looking at size, you’ll come across measurements marked as NEMA, which is short for National Electrical Manufacturers Association. For instance, you’ll see a stepper labeled as NEMA19, which means that the stepper’s dimensions are 1.9×1.9-inches. Generally, the bigger the stepper is, the more torque it will provide. However, that’s not always the case. It’s possible for a NEMA15 motor to outperform a NEMA19 motor.
Lastly, you’ll have to consider the motor’s internal resistance characteristics. Although this might not be indicated in the specification sheet, you should do some research on the models you’re considering. This is important because the stepper releases heat, and if it releases more heat than the motor can handle, it can lead to damage or improper function. On the other hand, the motor shouldn’t have a resistance that’s too high, as this may lead to the stepper not receiving enough current to operate properly.
Many small companies forget that managing technology is an integral part of running a business. While you do all your work, there’s a complex web of computers and servers behind the scenes to ensure everything is done as smooth and as fast as possible. For this techbone to function as efficient as possible there has to be a steady computer service supporting it. Finding the right IT professionals can help your business overcome technological emergencies, save money and power ahead for growth. No matter the level of IT support you need, consider the task of picking a computer support service as important as getting married. First, get assured they are the right for you, and only then sign a bound. These three steps can help you make a good pick. Here’s what to do next.
Several years ago, just before I went off to college, I got my first laptop. It was a Dell Inspiron N5110 and I was really excited about it because I’ve never had one before. A few months had gone by when I started experiencing the first issue – overheating. Dell laptops usually have a 5 year warranty, so I decided to take mine to an authorized Dell store for servicing. They said that they will need to clean up the fans and that should fix the overheating problem.
Nearly all businesses today are increasingly dependent on computers and IT technology. Whether you run an accounting firm or a small boutique, the computer is most likely your go-to tool for completing all day-to-day business activities and getting through the working day. Hence, ensuring your computer runs smoothly is crucial for accurate business planning and efficient work-flow.
NAS means Network Attached Storage and offers a high-capacity storage that is directly connected to your home or office network so any user can access the files from any device that is connected to the Internet. Here are a couple of things to consider before you choose NAS storage.
In general, cables are under immense temperature pressure because of the energy and heat that the flow of current through them emits. In order for extreme fire chaos to be avoided, the first thing to be taken into consideration is the choice of heat resistant materials for building those cables. There are various materials that can be used to provide insulation from high temperatures and make the cables useful.
High temperature cables serve to withstand extreme temperature changes that come down to extremely strong cold and hot influences. They’re designed with a special core and a layer of insulation made from a specific type of material depending on the purpose of use of the cable. The main areas where high temperature cables are used include power stations, iron works, foundries and factories for cement, ceramic and glass. They’re also used in aircraft construction and shipbuilding, brickworks and design of kitchen appliances – basically everywhere where constant flow of current is included and the result may be a fire caused by an overheated use of the device.
For these high temperature cables various types of materials are used in order to offer high functionality and safety. Among the most commonly used ones are silicone, rubber and fluorinated polymeric materials. The thing that distinguishes all of them is the specific area of application of each type: besides the aforementioned areas of use, heat resistant cables are also used in lamps and lamp holders in heat and air-conditioning systems and leakage monitoring systems. Each type of cable has its own specifics.
In applications where the cable insulation is subjected to dangerous and extremely high temperature fluctuations, silicone-rubber insulated cables are used. These cables can withstand temperatures of up to +220 degrees Celsius, but only on short periods. The lower range can go down to -60 degrees Celsius thanks to the weathering resistance these cables have, which is excellent. These are mainly used for applications in iron and steel works since they are also halogen-free.
Fluorinated polymeric cables
Also known as teflon cables, these are generally used in applications such as control cabinets that are subjected to high temperatures, like kitchen fitments, measuring appliances, heaters, brick-works and similar. However, these aren’t as heat resistant as the silicone-rubber insulated ones; their temperature range is from 100 degrees Celsius up to 205 or 230 degrees Celsius in some cases but for very short periods.
Besides these most popular types of cables and most frequently used ones, the market also offers variations of them with even more great features for an even higher degree of protection. With the addition of other materials like nickel, copper and steel, the cables gain even more strength and resistance features.
Outsourcing the IT support component of your business to a third-party company is not only the best way to save on operational costs but also to ensure proper maintenance of your system. There are many IT companies in Australia, however not all are trustworthy. If you do not want to risk your data, choose a reputable and trustworthy company. Here are some tips that can help you find the best one.
Think Global, act Local. Hiring a local IT support company can benefit you business more in terms of productivity and efficiency than hiring a company that is headquartered hundreds of kilometers away from your business site. For example, if you are located in Melbourne, you will get a reliable 24/7 service only if you hire a tech support company that is also located in Melbourne. No matter if you need a quick fix or a solution to a more serious problem, travel time and distance should not delay the response time of your IT consultants.
Check into the content of the Contract/Service Agreement thoroughly. Ask for a written contract where the type of services, for example server management, data recovery services, domains/web hosting or computer repairs, etc., the company provides are clearly listed. Also, in the service agreement the IT consultant company should provide the information associated with the performance of the personnel and the quality of the services. Such details include: approximate time needed for responding in case of normal or emergent IT issues, exact hours of availability during the day, time needed for resolving issues that happen commonly at your work site and so on. Also, the company should clearly list the prices for each type of services.
Choose a company that has high customer rating. Be sure you partner with the IT provider that has the expertise to provide reliable and satisfying solutions to your IT issues. Remember, there is never a good time for your system to fail, therefore find a trustworthy company that offers 24/7 support including remote monitoring. To make a good choice, the most important factors that you need to take into account include:
- number of years company has been in the industry
- qualifications, experience and certification of its personnel
- trust and security
- contingency planning
- response time.
Arm yourself with information before you hire. Read reviews online and ask for references from acquaintances, business partners and other companies that are in the same or similar industry as yours. A word of a mouth is in most cases, more trustworthy than any other form of advertising.
