A 21” LCD TV – A Versatile Mid-Range Size

by bestgeek on September 24, 2009

Some consumers consider a 21” LCD TV to be the perfect size: for TV viewing and for use as a computer monitor. Some take it one step further: they integrate their 21” LCD TV with a home theater PC. It’s easier than you think, and a home theater PC setup lets you access any media files like digital image files, audio files, and videos. You can also watch your favorite television shows or DVDs, and you can even use the 21” LCD TV as a computer monitor. It’s no surprise, then, that some consumers feel a 21” LCD TV is one of the most versatile screen sizes available.

If you watch digital TV on your 21” LCD TV, you could be already taking advantage of the possibilities of Digital Video Recorders (DVR) or TiVo. You can go one step farther; integrating your 21” LCD TV with a home theater PC setup is the ultimate in versatility. And it’s not that hard – here are a few ways available to you.

1. Buy a PC with the Media Center version of Windows XP and make sure it has a TV tuner card capable of capturing digital signals from your cable or satellite box. Once it’s installed, it works just like a DVR. You won’t need to buy a high-end PC to integrate with your 21” LCD TV if you just want to record and play shows and movies – if you also want to play graphics-intensive video games, you may need a more expensive PC with greater graphics capability. Just make sure you get plenty of memory.

2. Upgrade your PC. You can buy a copy of Microsoft’s operating system with Media Center. Frequently it comes bundled with a TV tuner card you’ll also need. If you have decent computer skills you can handle the installation fairly easily and your 21” LCD TV home theater PC setup will be running in no time.

3. If you don’t want to upgrade to a new operating system, a number of software companies produce applications that perform the same chores as Media Center does. A few are available as freeware, but the features they offer tend to be limited. You’ll still need to factor in the cost of a TV tuner card – a TV tuner card won’t be included with the freeware.

Once you’ve decided how to set up your computer, you can integrate it into your home theater system so your 21” LCD TV can handle the video feed you send to it. A 21” unit is ideal for this purpose; sets that are larger sometimes deliver reduced image quality when the TV signal is sent through the computer.

How you send the signal to your TV is the main hurdle to overcome. There are many different audio and video options for joining the two; the method you choose will obviously depend on the inputs and outputs available on both your PC and your TV. Older, standard-definition LCD TVs will have, at a minimum, a composite-video connection (a yellow video connection that’s usually accompanied by red and white stereo audio jacks). Hopefully, it will also provide an S-Video port. Newer 21” LCD TVs should provide component inputs, and more advanced 21” LCD TVs that are HDTV capable will supply DVI or HDMI inputs. If you haven’t purchased a 21” LCD TV yet, try to find a model with DVI or HDMI inputs.

Once your computer is connected to your 21” TV you can use Media Center to keep track of your media files and handle your DVR recording needs. If you want to record TV without using Media Center, similar products on the market can do the job. For example, SnapStream’s Beyond TV comes bundled with many TV tuner cards, so if you’re building a home theater or upgrading a machine you already own, you might end up with a copy by default. And you can take a further step and add the Beyond Media program for organizing photo, music, and other media files, and it does pretty much everything Media Center does. Beyond TV doesn’t support every TV tuner card on the market, so check the hardware specs for your 21” LCD TV before you install it.

Even if you have no interest in recording TV programs, you can still use programs like Windows Media Player, iTunes, and PowerDVD to manage your preexisting media library using software you already have.

Whichever option you choose, make sure you have plenty of hard disk space; once you start recording television programs or watching your home videos on your 21” LCD TV, you’ll find you need all the space you can get. And due to its increased versatility, you’ll find your 21” LCD TV is an even bigger part of your home entertainment system.

Air Compressor Buying Tips

by bestgeek on September 16, 2009

How important is air to human life? Since you started being aware of the things around you, you probably have considered the importance of air in one’s life and with the day-to-day activities that confront every person. Air does not only benefit all living beings. The use of a compressed air is widely used in several other areas, most particularly in the business arena. Compressed air is basically used as an essential part of a multitude of manufacturing, industrial, commercial, and automotive applications. The operation of an air compressor concerns a large percentage of the total expense cost of a plant’s utility budget.

1. How They Work

Air compressors work out by two different methods. The first is the air compressor that runs by electricity. The other one is the air compressor that runs by means of natural gas. Obviously, it is the air compressor that feeds on natural gas that is more cost effective among the two. An industrial plant will be able to save more and cut down the cost consumption when an air compressor by natural gas is employed. However, if the place for the working operation is located in an enclosed area, then it is health-wise to make use of an air compressor run by electricity in order to get rid of the gas fumes that may be a threat to the health’s safety of all the workers.

2. Suitable For Heavy Workload

If a business plant operates at a high level and needs an air compressor that will serve its purpose for heavy duties, then a two-stage air compressor is advisable. In more ways than one, this heavy-duty air compressor provides a higher level of efficiency compared to that of the smaller, single-stage air compressors. Also, this heavy-duty air compressor is also able to store large amounts of air needed for future use.

3. Types Available

If you are to buy an air compressor, it is best to think of its capacity to store compressed air. It is essential to consider the power delivered by the types of air compressors available in the market. A two-stage air compressor is more energy efficient compared to that of the single-stage compressor. Why? It is so because of the fact that the two-stage air compressor produces more air per unit of horsepower. Likewise, less heat is generated. Thus, paving the way for a longer life service. Take note that electric air compressors can also be utilized for light-duty applications. There are portable electric compressors that are handy to be carried from one location to another as you wish.

4. Excellent Results

Then, an air compressor buyer needs to bear in mind the efficiency rating of his prospect air compressor equipment. Surely enough, you would want every purchase to be not only valuable but capable as well. What will you do to an equipment that will not survive the tough challenge you require of it after every single cent that you have spent for it?

5. Considerations

In considering an air compressor for purchase, the ratings set by the mechanical engineers association can be the bases for the testimonies of the quality and protective features comprised into the equipment. Next, be sure that the air compressor that you are planning to buy includes a safety relieve valve for the escape of air if the tank’s pressure exceeds the maximum, a belt guard for protection purposes, and an enclosed air intake filtration system.

6. Attachments

The air compressors need to be secured with the attachments that are to be used for its connection to the air tube. The common tool attachments employed into the air compressor are the blowgun, a nail gun, air stapler, air sander, spray gun, or air ratchet wrench. It is the blowgun which is used for the compressed air to blow away the dirt and dust. The nail gun takes charge of the nail’s application even without the hammer. These tools are widely available in hardware stores for purchase.

When buying either a brand new or a second-hand air compressor, these things are to be carefully noted. It is for your own benefit both as the buyer and the user. Another tip to take note of is the frequency that an air compressor is to be used. If the air compressor’s use is called for in just a few times, then it is wise to just rent it. The tools as attachments can also be rented. If, however, the use of the air compressor is permanently required, then it will be better to buy one.
