How to Choose a Gaming Keyboard

Every year, manufacturers of computer hardware amaze us with new ingenious inventions. Many people like to spend their leisure time playing on the computer. It is very important for gamers to choose a good keyboard. Gaming keyboards come in different models and with different additional features. Thus, selecting a gaming keyboard becomes very interesting.

How to Choose a Gaming Keyboard

When you choose a gaming keyboard, it is worth considering the following parameters:

Additional Programmable Keys

A good gaming keyboard should have additional programmable keys. The number of these keys depends on the particular model. They may be from a few units to a dozen or more. These buttons can be programmed for a specific action in the game, or even for several priority actions.

Built-in Memory

You’d better choose a gaming keyboard with built-in memory. This feature allows you to reconfigure the keyboard. Thanks to its memory, it is able to store game profiles.

A Rubberized Key

The keyboard should come with a rubberized key. This keyboard is convenient because it will be able to replace some of the keys when they are erased due to the frequent use. Typically, the kit includes the replacement for these keys.

Backlit Keys

Many gaming keyboards are equipped with backlit keys. This is especially useful when playing in the dark or a dark room. The highlights come in different colors: blue, red, orange and green. The brightness of the backlight can be adjusted.

Additional Connectors

Some game models are equipped with additional connectors, for example, a headset, a microphone, and a USB port. All this contributes to the feeling of comfort during the game.

An Additional Screen or Analog Joystick

Good gaming keyboards are usually equipped with an additional screen or an analog joystick. Prestigious and expensive models are equipped with a screen on which the user can see how the game information and the state of the PC. The joystick helps to control the cursor with no need of looking up from the keyboard, which has a positive effect on the game.

Mechanical Keyboard

The mechanical keyboard is good because it does not require registration for full keystroke signal. In addition, the mechanical keyboard has a relatively longer life.

Recommendation

If you are badly in need of a gaming keyboard, I would recommend the Mantistek GK2. It is designed with a 104 full-size layout and adopts double shot ABS keycaps. And this 104 keys keyboard comes with the RGB backlight (9 kinds of backlit model for adjustment). In addition, it supports NKRO (no ghosting or key blocking), which issues that any number of key combinations can be used at the same time. And last but not least, it is a mechanical keyboard, durable and practical.

Play Fun Online Games for Kids

As we know, play is a child’s work that is why it is important that we choose games that are fun and educational at the same time. Today, almost every household has a computer and internet connection. It is not surprising that kids are on the computer or are learning how to operate one. They are born in a generation wherein having a computer is a necessity and it is important they learn how to use this at an early age.

One of the games that can benefit your child is typing games. You can find a number of free typing games online or there are some that require a license fee for a small amount. These games are a great learning tool for your child. Not only is it fun but it can enrich your child’s mind in various ways. If a child is learning how to read, this can familiarize him with letters, phrases and spelling. It can also help him learn numbers too. For the young child, this can help him in improving his fine motor skills because he is using his fingers to hit the keys. The music and playful graphics can really enhance his auditory and visual skills. This is also a good way for you to bond with your kids.

There are other online games that are available for kids. Again, this can be free of charge or you can get downloadable software for a minimal fee. You can get matching games wherein you can match the number to the set of fish. For bigger kids, games on geography, history and science are available. Make sure that these games are grade-appropriate and will suit your child’s ability. Games where you grow a virtual farm or a virtual aquarium are gaining popularity today. However, these are for older kids and for adults too.

All it takes is to search for “online games” on your browser and you see hundreds of matches. Keep in mind that these can be addicting, so make sure that you monitor your child’s playing time on the computer. Before anything else, always check the games first and make sure that the graphics are age appropriate.

MoS2 Low Friction Coatings – Not Just For The Aviation Industry Anymore

MoS2 low friction coatings (also known as molybdenum disulfide, also spelled, disulphide) are regarded the most widely used form of solid film lubrication today. What makes them unique (with the other dichalcogenides) is the weak atomic interaction (Van der Waals) of the sulfide anions, while covalent bonds within molybdenum are strong.Thus, lubrication relies on slippage along the sulfur atoms. All the properties of the lamella structure are intrinsic. No external form of moisture is required. In fact, best performance from MoS2 low friction coatings is attained in the absence of water vapor, which are prone to surface adsorption. This makes them ideal under vacuum.There are a number of methods to apply MoS2 low friction coatings, including a simple rubbing or burnishing, air-spraying resin-bonded or inorganically bonded coatings, and more recently by sputtering through physical vapor deposition (PVD).Thickness will vary, depending on form of MoS2 low friction coatings, but typically ranges between 5 to 15 micrometer. Sputtering techniques can produce thin films of 0.2 micrometer. While plasma sprays will result in higher builds, beginning at 0.003 inch or more.Friction coefficient less than 0.05 is attainable, but will also vary with humidity and sliding conditions. Tests show friction decreases with increasing vacuum strength. Friction also lowers with higher load, faster surface speed, or both. In fact, MoS2 low friction coatings are superior to both graphite and tungsten disulfide (WS2). Friction with MoS2 low friction coatings is independent of particle size, though the larger particles can carry more load.Dry lubrication for MoS2 low friction coatings remains superior at higher temperatures, with oxidation rates remaining relatively low at temperatures up to 600 degrees Fahrenheit. And in dry, oxygen-free atmospheres, lubricating performance, even with oxidation products, is stable to 1300 degrees Fahrenheit.Higher air flow can affect oxidation kinetic rates in atmosphere. Molybdenum oxide products (MoO3) and sulfur dioxide. Since MoO3 alone offers dry lubrication, based on its relative softness, molybdenum disulfide coating are ideal in higher temperature environments. At higher temperatures, though, they are better suited under vacuum. In atmosphere, they are prone to water adsorption from air based on their hygroscopic properties.As with the other dry film lubricants, while differences may prove negligible, you will have to determine which is better for you: longer wear life or better performance, using MoS2 low friction coatings. Generally, friction will be slightly higher by coating both surfaces, rather than coating one surface only. But wear life will increase coating both surfaces.Friction can be good in so many areas of life. Without it we could not easily stop and start our motion, or change direction. But in moving machinery, friction causes considerable loss of energy, poorer performance, not to mention limiting wear life.As with many non-lubricated systems, the static coefficient of friction is higher than the dynamic coefficient of friction. The resultant motion is often referred to as ‘stick-slip’. Basically, the two surfaces stick together until the elastic energy within the system has accumulated to some threshold, where a sudden, forward slip takes place. Under magnification, it’s apparent the union of two surfaces is often limited to intimate contact only at the tips of a few of the asperities (small scale, surface irregularities). At these point areas, pressures relating to contact may be near the hardness of the softer material. Thus, plastic deformation occurs on some localized scale. This is known as cold welding. Where bonded junctions are formed between two materials.For lubrication to occur, these bonds, this adhesive component of friction, must be broken. And this is where products like MoS2 low friction coatings serve well.So, where are these products used today? Consider aerospace, automotive, marine and electronic, for starters. There, you’ll find MoS2 low friction coatings, again and again.
