Creating A Home Theater

Saturday, June 12th, 2010

Shoppers in this new millennium are much more knowledgeable about electronic goods than people were at any time before. The older generation of today grew up in the 1960’s and 1970’s when everyone in the West had a television set and a stereo. Previous generations were not so fortunate for financial and technological reasons. Therefore, most shoppers nowadays have no problems about going shopping for complicated electronic equipment like a home theater.

It is in the shoppers’ best interest to research and understand about the components that go into making up a good home theater. It is not particularly exacting and many if not all of the elements involved have been around for at least a few years now. Consider what goes into a home theater:

a screen - can be a television screen, a canvas screen for a projector or a modern plasma or LCD screen. Stop thinking about the modern types of screen, they are still fundamentally TV screens and they have been around for 80 years or so. Same with a projector.

a player - a DVD player is just an enhanced CD player and they have been out for 20-30 years. You have probably had one for most of that time. (You can add another dimension to your home theater here by swapping an Xbox for the DVD player, but games machines are not new).

speakers - they are nothing new either. Speakers have been about as long as the television set.

So you see, there is nothing in that kit which you should feel uncomfortable about buying. Fair enough, you will be buying state of the art examples of what I listed above, but they are essentially the same. You connect them all together with their special plugs and wires and then plug them into the mains. Switch on and it will work.

So the next question is: do you purchase a package or do you buy the elements and build your own home theater? The answer to that question really depends on your level of competency. A package is easy and may work out cheaper too, but will it have the flexibility that you want? If you have a standard sized and standard shaped room, then I am sure that you will be able to buy a package that will suit you. If you think that the speakers are sub-standard, you could always sell them on and upgrade after a period.

if you want to be sure of getting precisely what you want, I think that most people will have to buy the components separately: that is screen, player and speakers.

The size of the screen depends on the size of the room and how close you are sitting to it: a distance of between three times and five times the diagonal of the screen is about right. However, some people like to be dominated by the screen and others do not want to wear their glasses, so it is up to personal preference.

The DVD player is a matter of individual preference too. They are all much of a muchness, but some people favour Sanyo while others favour Philips. If you want gaming capability too, use an Xbox instead of an regular DVD player.

Most rooms will require at least a 5.1 surround sound speaker set. These ought to be acquired as one package to make certain that they are all well-matched. That is five normal speakers and a sub-woofer.

Laptop Computer Reviews

Friday, June 11th, 2010

Laptop computer reviews are a very significant font of information for those who are interested in buying a new computer to help them in their work or to provide entertainment at home. But being an informed buyer is not an simple job for anybody.

Even though we may think that we are knowledgeable enough, we may later, discover that we were mistaken in the decision we took. Or possibly that mistake was made during the period before the decision itself was taken? During the research phase perhaps?

The rule of thumb is to try to read more than a few laptop computer reviews more before you think you have obtained enough information to be able to do what you need. Why is that so essential?

To begin with, laptop computer reviews are written by people who are paid to write quite a lot of reviews possibly even in one single day. As a result of this, whether the writer means to or not, he/she may end up saying pretty much the same thing about almost every laptop computer or even just glossing over the details.

Or, she/he may end up leaving sections of information out. Making mistakes is pretty common in human endeavour when fatigue and boredom enter the picture.

Another reason why you should read as many laptop computer reviews as you can is that this way you will definitely come across reviews made by some people who really make use of the laptop computer you are interested in. These forms of reviews and assessments are the ones that will most likely provide you with a truthful picture of how this laptop computer really works.

People who have actually used the computer will also have several points of view that big magazine reviewers may exclude from their pieces or reviews. These kinds of laptop computer reviews will also give you an idea about whether you are thinking about buying a laptop computer that is ideal for you or whether you are thinking about buying something that is too advanced for your requirements and so unnecessarily expensive, or too basic, and therefore cheap but useless.

Last but not least, different laptop computer reviews, especially if they come from several sites and consumers, will differ in the sort of information they will give you about the laptop computer. What may be absent from one assessment may be mentioned in another.

The whole mystery will not be ended until you finally own that computer. However, the greater the quantity of reviews you read, the more precise the image you will get. Above all, remember that ignorance of the facts could cost you dearly and more than that, might even land you with a low quality laptop computer.

Common Home Theater Mistakes

Sunday, May 30th, 2010

A home theater requires a sizable investment of money, thought and installation, particularly if you have a high quality home theater. Therefore, it is a shame that so may people just connect all the pieces in a room without giving any thought to what other things they should be doing to improve it. Unless you hire a professional adviser, you might not achieve the full potential of your home cinema system. However, it is not necessary to hire an adviser, if you just pay attention to a few common blunders made by a lot of home theater owners

The lighting in any cinema is very important, as I am sure you already know. Why is it then that many people do not treat it as important in their own home cinema? You never see external light - sun light - in a specialized movie theater and you should not want any in yours either. Hang heavy curtains over every window in the room and let them overlap the window by a good border.

Heavy curtains will not only keep external light out, but they will also dampen street sounds, something else you never hear in a real movie theater. If you have neighbours close by, it will also help to preclude them from being bothered by your loud films or music.

Do not try to save money by buying poor quality speakers. Do not mix and try to match speakers either, unless you are sure you know what you are doing. If you need five speakers and a sub-woofer, but can only afford three and the sub-woofer, buy speakers from a well-known brand that you know you can get hold of again.

Do not buy end of line speakers, as you will find upgrading hard. The best approach for the novice is to get a 5.1 surround sound set of speakers. Then, if at some point in the future you want to upgrade, you can quite easily, either by buying more or exchanging the lot in one go. One thing is for certain, a lot of the magic of going to the theater these days lies in the surround sound and you need to reproduce it at home.

It is not rocket science to put a home theater together whether it comes in kit form or not. However, if you do not feel happy setting it up, you would be better off having it done for you. Clearly, it is up to you how you go about this, but you could ask a relative or friend or neighbour or hire someone from the shop where you bought it. My guess is though that any moderately experienced eighteen year old has already seen one set up before and can do it for you.

Your movie theater, if it came in a kit, will or should have thorough instructions for you to follow. Please read the handbook before you start plugging things into each other. Read the manual and inspect the parts until you are well acquainted with the installation procedure and the recommended positioning of the equipment.

Make sure that the voltage is adjusted correctly before you plug it into the mains. Most equipment is made abroad for sale to many countries, so they often have some sort of selector for the voltage. Get it wrong and you could blow a part of the equipment, probably the amplifier, the DVD player or the screen. that could mean replacement of the module or poor reproduction of sound or picture.

It is not hard to get the installation of your home theater right, but you do have to pay some attention to detail, if you want to get the best out of it.

Home Theater Kits

Friday, May 14th, 2010

If you want to get a home theater system, there are a few essential principles that you should keep in mind. However, no matter how much advice you are given, if your level of know-how is insufficient to understand it, it is useless. Therefore, you have to be honest with yourself and admit to yourself how much you know.

Fortunately for most of us, the Baby Boomers are the most electronically wise older generation ever, because many of today’s older generation grew up in the 70’s when everyone had a TV and a stereo.

Music and sound quality is important to Baby Boomers. However, if you were one of those who was not engrossed in electronics, a home theater kit is probably for you. On the other hand, if you feel competent to take on the task, you will be better served by a system that you compile yourself.

This is not to say that kits are not much good, it is just that there are several variables that must be taken into account before purchasing a home theater system.

Sound or acoustics depends on the measurements of the room where the home theater system is installed, most of us realize that, but because we are unlikely to want to remodel the room to suit the theater, we have to select a speaker system to suit the room.

Likewise with the screen. Bigger is not always better. There is a ratio that can be used to help you work out the size of the screen you should be thinking about, but even this proportion depends on individual predilection.

The formula says that you should sit 9-15 feet away from a 36 inch screen, but you might have poor eyesight and prefer to have a 48 inch screen. This is where kit fall down.

In general, home theater packages suit regular shaped, smallish rooms. By that, I mean 12 - 20 feet in length and combinations thereof. Then, depending on the room again, you will have to consider the sound system. Stereo is not up to the job, if you want to replicate the sound of a full size movie theater. In order to do that, you will need surround sound with at least three speakers and probably five or more.

All in all, you will get the best system for your home movie theater if you buy the components separately, especially if you have an odd or oblong shaped room or certain personal preferences. However, a standard package delivers a quick and easy, passable solution for many modern, ’standard’ sized rooms.

One last piece of advice though, if you do buy a kit, make sure it is one that you can upgrade, particularly in the sound department. A TV screen is just a matter of a connection and they are all the same, but if your home theater package comes with three or five speakers, maybe you will want to add some more one day. You may also want to think about adding games functionality to your system too.

Home Theater Luxury Seats

Tuesday, May 4th, 2010

Many people like to relax after a hard day at work by going to the movie theater. However, if you go straight from work, you are likely to get trapped in a traffic jam and you will not have had the chance to freshen up. On the other hand, if you go home first to have a shower and get changed, sometimes you can not be bothered to go out again. That is how it works with me in any case.

So, would it not be lovely to be able to reproduce that authentic movie going experience in your own home? Not only can getting to the cinema be a nuisance, you can be hassled once you get there too. People talking through the film or giggling right behind you, someone with his feet up on the back of the seat next to you, cell phones ringing, babies crying… It is enough to put you off. And it is not even as if it is a cheap event anymore.

If you fall into this group, home theater was made for you. It is not essential to have a spare room in which to set up your home theater, you could just as easily use the living room. The size of the screen is critical, but that is a function of the size of your room or, more accurately put, a function of how far away from the screen you will sit.

If you need a very large screen, you could go for a projector, although for most people a 36 - 60 inch screen should be adequate. Then speakers. You must have surround sound or you will miss out on a lot of the authenticity of a true movie theater experience. Again, the number of speakers depends on the size of the room. A 5.1 configuration will do for most rooms. That means quadraphonic sound, plus one extra speaker under the screen and a sub-woofer.

If you like to play games, then you could substitute the standard DVD player with an Xbox for a truly awesome experience. Those are the basics of a medium to excellent home theater with possible games functionality, but there are other things you can do as well.

A set of heavy drapes is a good idea. They will not only stop light coming in, but the will muffle sound getting out Seating is a necessity and I would add a few occasional tables too for drinks and snacks. If the room is not near the kitchen, a small fridge would be useful too.

The seating provisions are important too. Some people just put a few couches in the room and that works well enough. Others prefer a few armchairs. If it is to be used primarily by children, half a dozen bean bags is all they require to have fun. However, if you or you and your spouse want to make the experience really something else, why not get a couple of recliners or even better still electric massage chairs? You could be sitting there watching a film with a drink and some snacks on a near-by table while having all your troubles and stress from work being soothingly massaged away.

Movie Theater Quality Sound At Home

Monday, May 3rd, 2010

Do you like going to the movie theater and get lost in the realism that their top-quality sound systems create? If you do, then I bet you are also one of those people who hates going there, only to have a potentially fantastic evening spoiled by irresponsible people talking through the film or letting their cell phones ring.

I used to be fond of the movie theater, but that was in the days when people respected the rights of others to listen to a movie in silence. There were no crying babies, ringing mobile phones or noisy youths in cinemas and if they got in they were soon kicked out if there was any noise.

Nowadays, cinema managers seem to take the easy route of letting these people spoil it for others. As a result, more and more quiet people are staying at home and the cinemas are becoming even noisier. If you are one of the stay-at-homes, but miss the cinema, why not recreate one in your home?

Build yourself a home cinema with surround sound. You will never regret installing surround sound in your home, because you will be able to play your favourite films, the TV and your music through it. The distinction between surround sound and stereo or even quadraphonics is breath-taking.

Different people have different requirements, aspirations, finances and even hearing ability, so it is tricky to recommend a system to a mass audience, but there are strategies for going about the purchase of your own home theater system. A lot of people buy a kit home theater. This is fine, if funds are limited, but you will want to upgrade the screen and the speakers before very long. If you just want to put a home theater in a small spare bedroom and do it quickly and easily, then this approach is for you.

If, however, you want a bit more, then you might prefer to get a bigger screen but make do with the speakers that came with the kit. These can easily be upgraded later. If you want to get everything part by part, you will need a screen, speakers and DVD player. If you would like to play games too, replace the DVD player with an Xbox.

But back to the speakers, whether you are renewing or putting your own system together, the strategy I suggest hold true. Write down the dimensions of your room or better still make a little plan of it to scale. Take this around the shops and malls and try to listen to a few set-ups in a room similar to your own. This could be difficult, but you might be fortunate.

Decide whether you need a 3.1; 4.1; 5.1; 6.1 or even 7.1 set of compatible surround sound speakers. Basically, it all depends on the size of your room, but the shop assistant will be able to demonstrate and advise you. As a guideline, a 5.1 surround sound set will be sufficient for most rooms. The figures stand for normal speakers and sub-woofers: ie 5.1 means five normal speakers and one sub-woofer.

The arrangement of the speakers depends on the size and shape of the room and on your personal preference, but the standard layout would be: one speaker the far left and far right of the screen and one underneath it with two more speakers slightly apart from each other at the back of the audience. The sub-woofer can go at the front or the rear.

Selecting A Screen For Your Home Theater

Saturday, April 10th, 2010

If you are considering setting up a home theater system, then there are three essential pieces of equipment to consider. They are the screen, the speakers and the player. Two of these pieces of equipment are directly related to the size of the room in which you will be sitting and where you will be seated.

All DVD players over a certain price are fairly good and you ought to listen to a couple to make up your mind. The same with speakers, although how many you will need is dependent on the dimensions of the room. The screen is more important and that is what I want to talk about here.

It will not actually be of very much help to you to just walk into a department store which stocks fifty or sixty television sets all in rows. You may find that you have a preference for one screen’s colour display over another, but the colours are controllable anyway by brightness, contrast and colour mix. You need to view the screen as it will be seen in your home theater.

In order to do this, I always advise getting a pen, paper, preferably graph paper, and a rule. Draw in the proportions of the room to the largest scale that the sheet of paper allows, maybe one inch for two feet or there abouts. Then draw a line to represent the screen against whichever wall you choose and finally add a few squares for the seating. Now measure the space between them and write that figure down, because it is very important.

Using our scale above, if the gap on paper between the screen and the seating is five inches, the distance in the room will be ten feet and ten feet is 120 inches. A good rule of thumb, when trying to work out screen size is the same one used for paintings, which is that the ideal viewing distance of a picture is between three and five times its diagonal measurement. Therefore, in our illustration, the ideal screen size should be between 40 and 24 inches. However, many experts put a minimum screen size for a home theater at 28 inches.

That may come as a bit of a surprise to many of you, because a lot of people think that the solution is the bigger the better. However, primed with this information, now go to the TV store and look at the models again. You will find that if you get up too close to some sorts of screen the picture becomes rather poor, particularly with conventional television screens. Plasma and HDTV allow you to get a little closer without losing quality.

Another factor is your age, or at least, the quality of your eyesight. Would you rather watch the film with your glasses on or off? Off for me, so I would tend towards the higher end of our scale or maybe even go above it. My eyes are not going to get any better, but I can always put my glasses on when the time comes that I cannot see my screen properly any longer. However, I want to put that time off for a while yet, so I would go for a 48 inch screen in this illustration for my home theater. Plasma, if I could afford it.

Electric Massage Home Cinema Chairs

Saturday, April 3rd, 2010

After you have finished planning the layout of your home theater, the next step is to settle on the accessories. Things like floor covering, lighting, decoration, curtains, and furnishings, like a small fridge, some small tables and chairs. If you are planning your home cinema just for yourself, then maybe you can afford to really splurge out on a really top end home cinema chair.

After a hard day’s work or exercise, your muscles can become taut, especially in your neck and shoulders. The best way of relieving this is some destressing exercise like yoga or a massage, but most people do not want to take up yoga postures after work, so they would go for a massage.

This is all well and good, but then you would have to shower, get changed and drive down there and sometimes you just can not be bothered. You could phone a massage parlour and have them send someone to your house! That sounds great, but no, you are not going to do that either.

So, why not go for the next best thing. Get yourself an electric massage chair for your home theater? You could kill two birds with one stone. You could spend an hour and a half watching a film, while getting all those aches and pains gently worked away.

A massage chair can never totally replace a masseur or masseuse, but many regular massage parlour goers say that it is a good second best. The point is though, that you can have a soothing massage every day of the week, which some people say is preferable to one heavy massage once a week. You masseur or masseuse right there in your own home cinema willing to work for pennies a massage any time of the day or night and while you are at the movies too! Think of it!

Using an electric massage chair as your home cinema chair (or one of them) is a great idea. While your mind is being taken off your daily troubles and strife, so your body is being relieved of the tensions that have built up there too. You can recline in your home cinema chair and have the head rest massage your neck, while the back rest massages your lumber region, soothing away those aches and pains in a gentle, but efficient way.

The great majority of these electric massage chairs come with a remote control, so it is very easy to switch cycles on and off or repeat them at will. Some are programmable too, so that you could build up your own massage sequence, once you get used to what your new home cinema massage chair can do.

Imagine having it start at your neck and calves at the same time with the two massage points slowly converging on the small of your back. Or beginning at the small of your back and then radiating up and down your body at the same time. You would need two masseurs to do that and all while you are sitting in your home cinema chair watching a movie.

Home Theater Set-Up And First Rate Speakers

Tuesday, March 9th, 2010

Home theaters are very popular in the West now for many reasons, but partly due to the recession. However, I predict that after the downturn is over, home theaters will take off like a rocket. In my opinion, this is because, the recession has forced people to examine their spending, which normally means cutting back. Going out, eating out and movies are all in the front line of these cuts. However, the slump is upsetting and people have to get some enjoyment from somewhere.

In the medium to long term, it is cheaper to put together a home theater for a family than take them to a proper movie theater every week. Taking a family of four to the movies costs $50-$100, whereas a decent home theater might cost $1,000. It does not take long to recoup those costs. And it saves you the bother of travelling there and back, the noise and mobile phones during the film and high prices for candy and snacks.

OK, maybe people at the moment are buying cheap packages of home theaters, but one of the first things they will replace when they get a bit of money again will be the speakers, I bet. Evidently, you need a good quality, large screen, but after that, it is the sound and the bulwark to good sound is usually poor speakers.

The most important factor in the design of your home theater is the dimensions of your room. If the room is small, you will not have need of so many speakers. Perhaps three speakers will be sufficient, if the room is small. However, if you only need three speakers and a sub-woofer, get good ones.

If you have a bigger room however, the basic three home theater speakers may not be enough. You may need to put up to six speakers and a sub-woofer around the room. The position of these speakers is up to you and can depend on the shape or and size of the room anyway, but typical layouts are:

3.1 system: one speaker to the left of the screen, one to the right and one below it. You can put the sub-woofer on top of the central speaker or at the back of the room. Try it and see.

5.1 system: as 3.1, but with two speakers at the back of the room too.

6.1 system: as 5.1, but with another speaker between the rear speakers, as in the front.

7.1 system: as 6.1, but with two speakers central rear, slightly away from each other. You can move the existing rear speakers around to the sides too.

This set-up requires a lot of wires as you can envisage. Now, you could staple the wires to the skirting board, but you should only do that after you are dead sure that you have the speakers in the right positions. Or you could hang the speakers on the walls. However, although that sounds good for music, it does not always sound all right for a movie.

The best option is wireless speakers. Wireless speakers can be moved around to suit the number of people watching the film or moved out for cleaning or redecorating purposes. You do not want to bash your nice, new, expensive speakers with the vacuum cleaner, do you?

Free Computer System Security Measures

Sunday, March 7th, 2010

Today, more and more people are using their computers for everything from communication to online banking and investing to searching. As we do these things on a more frequent basis, we open ourselves to prospective hackers, attackers and crackers.

While some may be hoping to phish your personal information and identity for resale, others want to use your computer as a platform from which to attack other unsuspecting targets. Below are a few simple, cost-effective steps you can take to keep your computer more secure.

1. Always make backups of essential data and store it in a safe location away from your computer.

2. Update and patch your operating system, web browser and software frequently. If you have a Windows operating system, start by going to windowsupdate.microsoft.com and running the update wizard. This program will help you find the latest patches for your Windows operating system. Also go to officeupdate.microsoft.com to locate possible patches for your Microsoft Office programs.

3. Install a firewall. Without a good firewall, viruses, worms, Trojans, malware and adware can all access your computer from the Internet with no trouble. Thought should be given to the advantages and differences between hardware and software based firewall programs.

4. Check your browser and email settings for maximum security. Why should you do this? Active-X and JavaScript are often used by hackers to plant malevolent programs into your computer. While cookies are relatively harmless in terms of security concerns, they can still track your activities on the Internet to build a profile of you. As a minimum precaution, set your security setting for the ?Internet zone? to High, and your ?trusted sites zone? to Medium Low.

5. Install antivirus software and set for automatic updates so that you receive the most current virus files.

6. Do not open unknown email attachments. It is simply not enough that you may be familiar with the address from which it originates because many viruses can be spread from a familiar address.

7. Do not run programs from unknown sources. What is more, do not send these kinds of programs to friends and colleagues because they contain funny or amusing stories or jokes. They may contain a Trojan horse just waiting to infect a computer.

8. Disable hidden filename extensions. By default, the Windows operating system is set to ?hide file extensions for known file types?. Disable this option so that file extensions display in Windows. Some file extensions will, by default, continue to stay hidden, but you are more likely to see any unusual file extensions that do not belong.

9. Switch off your computer and disconnect from the network when not using the computer. A hacker can not strike at your computer when you are disconnected from the network or the computer is off.

10. Make a boot disk on a floppy disk or CD in case your computer is damaged or infected by a malevolent program. Clearly, you have to take this precaution before you are subject to a hostile violation of your system security.
