A Trip Down Memory Lane - Sony Walkman To Apple iPod

There may be some of you reading this, that can remember something called a Sony Walkman. Now if you are not old enough, just ask your parents or even an older brother or sister. What you will see is this kind of smile come over their faces. Boy, does time fly and technology goes even faster.

You see, if you lived back in the 1980's, the Sony Walkman was the coolest thing on the planet. Now if you did live back then, you probably owned one of these. This product was the rave. This product was everywhere, in the airports, the malls, on buses, everywhere. You would see the kids in the back seat of the family car, listening to their own thing, using the Sony Walkman. Their parents would be listening to something else (Dean Martin or Perry Como), which the kids hated.

A phenomenon is a term that implies that something is here today and then gone tomorrow. The Walkman was beyond a phenomenon, it was a mainstay. It was a staple of the society in which it was introduced. If there was a time capsule created to represent the 1980's, the Walkman would have to be included. If you were to not include it, would be the same thing as discussing technology of the 21st century and leaving out the part about the internet.

Now for the next generation of personal entertainment devices, from the Walkman to the iPod. I am not sure how you could avoid not knowing about the Apple iPod, unless you happen to be living in that time capsule we talked about earlier. So, you have seen them, they are everywhere (sound familiar?). If you ask 10 people to explain what an iPod is, you'll likely receive 10 different answers; and all of them will likely contain some element of fact and logic. Introduced by Apple Computers in 2001, the iPod is technically defined as a portable music player; and even this doesn't do it justice. Today it is so much more.

Now the Walkman was really for the kids, that is who mainly used it. Not today and the iPod. It is not just for kids anymore. You see more than just kids walking around with these little white wires sticking out of there ears.

The Apple iPod is a truly amazing product. It has crossed the demographic consumer lines. You see people of all ages wearing these things: from the teachers, the kids (big and small) to the senior citizens, the athletes who manage to keep the ear buds in place despite doing whatever there sport happens to be.

Now, don't panic if you haven't entered the iPod country yourself. There are so many to chose from: the iPod classic, iPod shuffle, iPod nano, the iPod mini and so much more. And lets not forget about all the iPod accessories that go along with this. Though the iPod are so incredibly popular, there are still enough people out there who haven't tried one yet. And there are still people out there who have the iPod and haven't even taken it out of first gear yet. Why is this?
The reason is because technology can seem confusing and despite its small size, figuring out the in's and the outs of the iPod can seem intimidating and time consuming. In fact, nothing could be further from the truth. The iPod is built around the reputation of Apple which is base things on simplicity and ease of use. Just like the Mac computer. The iPod is as easy to use as a DVD player, or maybe even easier.


In closing here are some facts about the Apple iPod that you may not be aware of. I am sure you know this that the iPod is the
#1 selling digital music device. What does it take to be the
#1 selling device in this competitive marketplace? Here are some facts. Since 2001 there have been 110 million devices sold world wide.

Now if that does not make you go WOW, to the Apple iPod popularity, I am not sure what would. It's no wonder, given these awesome sales total, that the question most people ask these days isn't: are you getting an iPod, but rather: where is your iPod?

Four Essentials to the Ultimate Home Theater System

The high-definition television revolution is already under way, as most of the major TV networks and cable outlets are quickly adopting this cutting-edge version of digital television as their broadcasting standard and offering consumers more shows in high definition.

In fact, according to the Consumer Electronics Association, 9 million households are likely to purchase HDTV products during the next 18 months. Another 30 million consumers consider themselves likely purchasers within the next three years.

This newer technology can be overwhelming for consumers, especially when they are not properly educated about the tools needed for the best setup of a high-definition home theater system.

Four basic elements are needed: picture, source, sound and assembly. Interestingly enough, the CEA says that approximately 30 percent of U.S. homes already have these basic ingredients.

* Picture: Most digital, high-definition televisions feature large screens in widescreen formats that create a theater-like experience right in your home. HDTV delivers crisp images that make you feel like you're part of the action.

Plasma and liquid crystal display televisions have generated the most excitement so far. These thin, lightweight sets can hang on a wall and only take up four inches of depth. Other examples include the microdisplay rear-projection televisions such as digital light processing sets. These TV sets are thinner, lighter and brighter than traditional projection TV sets.

* Source: Some high-definition televisions have a built-in tuner to receive local high-definition broadcasts. These are referred to as having "HD Built-In." Sets without an integrated tuner are "HD-Ready" and need a set-top box to decode the high-definition signal. Starting next year, many digital televisions will come with a high-definition tuner and the cable box built in, simplifying the connection for consumers.

* Sound: Most people don't realize that the high-definition television format incorporates digital 5.1 surround sound into high-definition broadcasts, giving you that "in the middle of the action" feel. For a truly engaging viewing experience, it is important to get a sound system that is comparable in quality to your television.

* Assembly: To tie it all together, you need to make sure you have the right cables and accessories to connect your system. Many consumers prefer using service personnel to deliver and set up the system at home - making sure everything is in place, connected and calibrated for the optimal home theater experience.

So how much does a home theater system cost? A wide range of prices are available, depending on an individual's needs and desires.

Digital Projector Guide- Some tips for Digital Projectors

Digital projectors are equipments of modern technology. These are used to convert image data directly from the computer onto a screen via lens system. Digital projectors provide visualization of data that is actually stored in a computer for presentation. These projectors enable the viewers to watch moving images from a DVD, digital versatile disc player. Advertisers or sellers also use these projectors to give demonstration of products to a large number of customers. It can easily convert written documents onto an interactive whiteboard.

Digital projectors play an important role in the formation of home theater systems. These projectors use resolution of SVGA standard i.e. 800×600 pixels in expensive devices. Cost of digital projector is determined by its resolution as well as its brightness. If you’re going to use it in large rooms or big conference halls its brightness should be from 1,000 to 4,000 ANSI lumens.

First digital projectors, Eidophor projectors were introduced in 1950. Eidopher projectors used an oily surface in a rotating disk with light shining through it and employed an electron beam to disrupt oil in a specific manner. Eidophor projectors were not able to produce colors. Nowadays there are several high quality models of digital projectors are available in market so Eidopher projectors are less common.

Following four technologies are used in digital projectors:

High intensity CRT
LCD projectors using LCD light gates
Texas Instruments' DLP technology
Eidophor oil-film projectors (obsolete)


At present LCD projectors use Texas Instruments’ DLP technology whereas the high intensity CRT devices are suitable for enduring installations. Entire working of cathode ray tube digital projectors is like CRT television set. These projectors may be configured with one RGB color tube that has three colors red, green and blue with a single lens, one black & white tube with a rotating color wheel or three RGB color tubes with three lenses.

Projectors having cathode ray tubes are usually bulky thats why these are the best projectors for fixed installations.

LCD digital projectors are portable and lighter enough in comparison to CRT and can be easily shifted from one place to another. These are very much popular and available in various shapes and sizes. CRT and LCD digital projectors come under the category of transitive projectors.


Reflective projectors are the superior digital projectors that provide high quality images. These are affordable and offer next level of entertainment. Everyone can enjoy home theater applications with the help of digital projectors.

Digital Cameras - A Guide To Buying

Digital camera sales are going through the roof. As the quality of images from digital cameras improve they are becoming much more affordable and the sales are simply not surprising. Consumers are also becoming more comfortable with the whole idea of taking of photographs digitally.
In choosing a digital camera take into account your basic needs and what you plan to use the camera for.

Digital camera types:
It doesn’t matter whether you're shooting film or digital images there are basically three types of cameras. There are point and shoot cameras, prosumer cameras and professional quality cameras.

1. Point and shoot cameras operate automatically. They do everything for you except for framing the subject. Exposure is decided by the camera as well as whether a flash is needed or not. All you need to do is to point and shoot.

2. Prosumer Cameras. This camera is a step up from your typical point and shoot because it allows the photographer not only to shoot in a fully automatic mode but also to have control over various aspects of the exposure. They typically have various modes including portrait mode, a close-up mode, action mode, and landscape mode.

Resolution: It doesn't matter what sort of camera you decide to get you will have several decisions to make regarding resolution of the camera.

The salespeople of most electronics superstores are quick to tell you that the most important thing to consider when buying a digital camera is how many pixels there are. Now while it is important it is not the end all of digital image quality. Pixels are tiny squares and in some new models they're starting to use other shapes as well. The more pixels you have in your image the sharper the detail of the image will be.

Most current digital cameras on the market today will produce an image with more than 4 million pixels. That's enough resolution to easily print images up to 8 x 10 with good image quality. Is not likely that you will print images larger than 8 x 10 and so most of these camera should meet your needs.

Try various digital cameras before you purchase:

There is a wide selection of digital cameras on the market with various image qualities even though they may have the same number of pixels. There are different kinds and sizes of image sensors, which is the chip that actually records the picture. It is recommended that you take a memory card into the store with you so that you can put it in each camera and take sample photographs that you can then take home to view on your computer to compare.

The technology is constantly improving and digital cameras will be constantly changing. Don’t be surprised if several months after you purchase one there is one that is new and better with more pixels. If you take the time to choose a good quality digital camera which makes good photographs you'll be able to enjoy digital photography for a long time in the future.

If you do make the move into digital photography remember this. Many people using digital cameras simply put their photos on their computers and never actually make prints anymore. It is easy for these photos to get lost and therefore it's recommended that you print special photographs for generations to enjoy.
