How You Can Increase The Lifespan Of Your Projector Bulb Or Lamp

The replacement of projector bulbs is an all-too-frequent occurrence for anybody that has owned a home theater projector for any length of time. While a two thousand hour lifespan may sound like a lifetime to some people, rest assured it is not long before the projector lamp will need replacing. There are however, some general tips that can help to expand the life of a headlamp for the projection unit.

Do not touch the lamp with bare hands
One of the most frequent problems encountered is people replacing the bulbs with their bare hands. While this is fine for an ordinary light bulb, it is not a good practice for a projector lamp. The lamp in a projection unit burns much hotter than any regular light bulbs. The effects of touching it with bare skin are equally magnified and problematic.

Touching a projector bulb with the bare skin leaves traces of oil on the lamp surface. While this may seem a very minor detail, it is detrimental both to the bulb and the quality of the resulting multimedia display. The oils will get burnt onto the lamp and drastically reduce the lifespan. As the oil is baked into the surface, it actually diffuses the light being projected, reducing the lumens actually being sent to the refractive surfaces. The light will not be enough to project the image that has come to be expected from the home theater projection system. While the problem may not be noticeable at first, over the course of a little time, the quality will degrade to the point of not being viewable.

Turn off the projector power after turning off the lamp
It is highly recommended to turn the power on the projector to the ?off? position only after having turned off the lamp and allowing it to cool. This will allow the cooling fans to do the job they were designed to do. While rapid cooling and heating result in repeated contractions and expansions of the bulb filament, it is much better that it be done more quickly with the cooling fans. Likewise, turning the projector on and allowing the cooling fans to run for a moment before turning on the lamp will help as well. This will add hours to bulb life expectancy and allow for longer hours of viewing pleasure on the home theater projection system.

Constant Movements
Constantly bumping or moving the projector, especially while it is hot can be very detrimental to the projector lamp. The filament in the bulb loses almost all tensile strength when it is heated during normal usage. It is much the same as the filament in a camp lantern. The principle is the same; the filament effectively becomes almost the same consistency as ash, making it extremely vulnerable to damage when it is hot. Even after proper cooling, the lamp filament is very sensitive. Care should be taken when moving the projector for whatever reason. While it is always a good idea to be careful with electronic equipment, some aspects of the home projector are actually a bit more sensitive.

It will usually be necessary to move the projector when cleaning the filters. As always, it is a good idea to move it carefully without jerking it around or bumping it any more than needed. Taking an extra moment or two to check the projector mount and make sure it is still securely fastened can also be beneficial and prevent slips and movement which may otherwise be harmful.

With a little care and a little preventative maintenance, the projector lamps will still need to be changed, but not nearly as often.

Camcorder Batteries

Digital camcorders of today have come along with highly efficient batteries that last longer and give you the utmost satisfaction. Camcorder makers in the recent years have striven ahead in making the battery life longer and longer. Thus, the hassle of charging your battery every time you need to shoot is minimized.

Reputable camcorder manufacturers like Sony, JVC, Panasonic, and Canon are now competing to give you a better battery performer. Meanwhile, the sizes of these camcorders?whether a DVD format or not?are getting smaller and smaller each day. With miniaturization arises the problem: a small camcorder means a smaller battery that would need to remain charged for a longer time span.

Most of these models, however, run on lithium batteries that not only last longer but also give better results. Professional camcorders, from the Sony or Canon genre for example, do give up to a three-year warranty on their batteries. But the market has something else to offer as well: unbranded but great performers. Lithium batteries made by less-reputed brands also work well. Thus, professional shooters as well as amateurs are increasingly depending upon these versions after the original battery dies out, as the less well-known brands are cheaper and continue to give the same output.

But while purchasing these unbranded batteries from a retail outlet in your city or from an online store, take caution. You need to understand few criteria. You should compare prices and warranties, if available, on the battery. The credibility of the online store or the manufacturer and the longevity of the power provider can be of much help to you. It has occurred many a time that people have simply paid for a particular battery on the web and are still finding it difficult to have it delivered.

Television: Getting the Big (and Better) Picture

Television viewing has certainly changed over the years. From black and white to color in the early days, to the ever increasing size of screens more recently, the home viewing experience is improving. The more recent quest has been focused on increasing picture quality with better color accuracy and clarity. As a consumer, it can be difficult to keep up with all of the terminology and the features of the various types of televisions. For those who have not dedicated time to keep up with this changing world of television, a very brief overview is in order to help in the search for a great picture.

The first step in getting the best possible picture is to receive the best possible signal, which at this time is digital. Satellite TV and digital cable offer the majority of digital television out there at this time. However, changes in broadcasting are forthcoming as all major networks should discontinue broadcasting analog signals and convert completely to digital by February 2009. Digital signals offer many advantages but the most obvious result will be a higher quality picture (and sound). With this change, owning an HDTV set would be of benefit although owners of analog sets will probably be able to purchase inexpensive converter boxes to be able to view the digital signals. Of course, if users want the full picture such as what they see in movie theaters, they will need a wide screen with 16:9 aspect ratio versus the 4:3 aspect ratio seen in most traditional sets.

Secondly, a few words about HDTV are in order. HDTV is one form of digital television. It transmits six times more information than you get through analog TV. This gives the viewer stunning pictures with far greater detail, clarity, and color accuracy. An HDTV is capable of displaying resolution of 480i, 480p, 720i, 480p, 720i, 720p, 1080i, 1080p. The i means that the signal is displayed on the screen interlaced and the p means that it is displayed by progressive scan. Progressive scan generally produces a higher quality picture. The highest quality signal a conventional TV offers is 480i, but this is the lowest quality signal for an HDTV. Potential buyers looking for the best picture should accept no less that 720p.

Numerous technologies such as plasma, LCD, and DLP provide displays with outstanding color accuracy, contrast, depth, and clarity. All have a good life span, dependability, and work well in most environments. The choice is primarily based on personal preferences although plasma screens are not recommended for locations at altitudes over 6,500 feet. Plasma tends to offer the largest of screens and is somewhat less expensive than LCD screens of the same size. LCD screens on the other hand emit less heat and use less energy.

Obviously there are many options for getting an outstanding picture to enhance the viewing experience. As there are a number of great technologies, the type of display is less important than getting a digital signal and a set that can both receive the full high definition image and display it with the best possible resolution.

InCeiling Speaker Install Audio Concepts BFlat Coax 8"

This weekend I finally got around to finishing my Audio Concepts B-Flat Coax 8 in-ceiling surround speaker install. I detached the B-Flats from their ceiling mount and stuffed fiberglass insulation (the cotton candy kind, rated R13) in the cavity between ceiling joists. According to the B-Flat installation instructions and in-ceiling/wall tips elsewhere, the insulation should improve sound quality. The end result was not what I expected.

Surround satellite speakers in multi-purpose rooms have always been a problem. Where do you run the long lengths of cable? I?ve tried wireless speaker systems at various frequency and have never heard anything but static. You can try running your speaker cable along your baseboard or even opt for a raceway system like those sold at Cable Organizer. What if you have to jump a doorway, opening to another room or get around a large fireplace?s brick fa?ade? In-ceiling and in-wall speaker installs have the highest wife-acceptance-factor (WAF) because of their invisibility. You get to run your speaker cable inside the wall then to the attic and then back down inside a wall to the speaker.

My in-wall speaker needs first arose with the set-up of my living room home theater in my new house. I had the TV and equipment cabinet against the north wall and needed to get surround sound behind the sofa sectional on the east and west walls. To the east I needed to pass a bank of three windows to the wall area behind our chair-and-a-half. The west side was not so simple. The north end of the living room opened up to our dining room, presenting a 10 ft gap to traverse with no moulding or other architecture to hide wires behind. The living room?s west wall has about six feet before the kitchen?s east entrance. I could hide speaker cable along the east side?s baseboard run. I could do the same on the west side if I ran the wire around the dining room, over the north kitchen entrance, then onto the baseboard of the west wall. This amounted to more cable than I was willing to buy and install.

Running in wall speaker wire through my attic looked like the best solution. Unfortunately, I have no desire to venture into the attic with its past or present wasp nest, blown in insulation and cross beam obstacle course. The trap door to the attic is in the ceiling at the south end of the house opposite the living room. I can?t imagine stepping from ceiling joist to joist without putting a foot through the ceiling. Could I find a compromise between invisible in wall wiring and easy but ugly along the baseboard wire?

DeCorp Dewire is a thinner than a business card ribbon of speaker cable that is first glued to your wall or ceiling and then spackled, sanded and painted over for a virtually invisible cable installation. I measured the two runs to my proposed surround speaker locations on either side of the living room. I ordered the Dewire flat speaker cable, their special spray glue, spackle and banana plug and pin terminations. The Dewire would run straight up my wall, across the ceiling and the down each side wall to connect to the speakers. This the same route the in-wall attic run would make but without the attic.

After some searching of the major home electronics magazines and review sites I found little in the way affordable in-wall speaker recommendations. The Audio Asylum and AVS Forum communities pointed me toward the Audio Concepts B-Flat 8 Coaxial In-wall loudspeakers. For under $200 the B-Flat?s promised performance rivaling $1000 in-walls.

After the careful purchase of the surround speakers, the invisible speaker cable and a drywall saw, I failed to ever install the speakers. Other home projects? precedence was my excuse. Really, I just dreaded the thought of gluing the cable to the wall and ceiling, and then plastering over the wire sloppily and making a mess of my wall. My lack of experience with a trowel and spackle knife paralyzed me.

Months passed. I avoided watching any movies that promised a dynamic and exciting surround mix. I was stuck with stereo. My wife and I endured one romantic comedy after another. Then everything changed.

We refinanced our house last summer including an equity line of credit. My wife got to upgrade our kitchen, hallway bathroom and lighting while I got to build a humble front projection home theater in half of our basement?s rec room.

In this new home theater I could use the B-Flat in-walls as in-ceilings. An in-ceiling install rated high on the WAF scale. Electricians ran the Dewire flat speaker cable through ceiling and out through the square holes they cut for the B-Flats. I was not using the Dewire as intended (glued to a wall and hidden under spackle and paint just like a drywall seam), but I already invested nearly $200 and the Dewire does the same job as in-wall rated speaker cable.

I installed the B-Flats myself after the electricians finished the more difficult hole cutting and wire running part of the process. I simply tightened the four screw posts at each corner. The screws will rotate a clamp that catches and holds the other side of the drywall or ceiling board until tight. An electric screwdriver will speed the tightening of the long screws. You have to balance the coaxial speaker driver and surround in one hand while you tighten the four screws. The only bad part of this process was the extra heat near the ceiling. I was sweaty. I was careful not to over-tighten the screws as the clamp mechanism was all plastic and the ceiling board can easily be crushed back to ripped paper and drywall dust.

Next I calibrated with the Avia Guide to Home Theater DVD. Avia?s 85 db test tones proved stressful for the B-Flats. I detected some clipping when I bumped up the surrounds? levels to reference level. The clipping is not an issue while watching a DVD or playing a video game. I never raise the volume of the Onkyo TX-DS989 AV receiver above -15 db (0 is reference). The initial calibration pushed the surround levels to +6.5 and +7 (the front stereo channels are set to +4)

After stripping out of my insulation protective gear (gloves, painter?s cap, safety goggles, respirator and Tyvek cover-alls), I recalibrated the surround sound channel balance. To my surprise, the surround levels needed another decibel to reach reference level. I thought they would need less power with the insulation?s damping.

Of course, I have only run the test tones through the B-Flats. I haven?t had the chance to listen to any DVDs yet to see if my insulation made a difference. I am hoping what loudness I lost is gained in clarity, tonal accuracy and imaging.

Father, Husband and Geek. My geeky interests have not changed since I was a kid. I still love comic books, anime, role-playing games, console video games, indie rock, imported toys and mecha models, bad American and great British sitcoms, and all the tech that let?s me experience these hobbies to their fullest. Now that I?m married with children, I?ve had to strike a balance between supporting and pleasing my family and feeding my geekery hunger. Lucky for me, my wife is very accomodating and even geeks out with me on occasion (the ladies love Joss Whedon?s Firefly). My two year old likes anything that moves on the front projection screen and makes noise, so far she is easy to please. Geekwithfamily.com exists to enrich the lives of fellow geeks and the friends and family who put up with them.

What Your Eyes Should See With And Your Ears Should Hear With

It is not very often that competitors come together to agree on anything, so when they do it should be considered quite an event. Some interesting developments are happening in the CE industry.

The biggest names in Consumer Electronics,including Hitachi, Matsushita Electric Industrial(the Panasonic Brand) Phillips,Sony,Thomson,(Rca) Toshiba, Silicon Image have established Hi Definition Multimedia Interface as the defacto standard for High definition and the consumer electronics market.

HDMI combines uncompressed HiDef video and multi-channel audio in single digital interface, providing crystal clear digital quality over a single cable. HDMI can be thought of of a connection or interface between digital audio video sources such as DVD players,A/ V receivers,set-top boxes and compatible Digital audio/ video monitors such as digital television. The analogy is like that of similiar interface of which we should be familiar such as the

RS232C connections which are common between computers and modems, computers and printers, and between two computers. or the RJ45 which connects the computer to the telephone line.

HDMI has found support from the major motion picture producers that include Fox,Universal,Warner Bros. and Disney. The system operators DirectTV and EchoStar(Dish Network) CableLabs and Samsung are also throwing support behind HDMI. Digital Content Protection LLC (a subsidiary of Intel ) is providing High bandwidth Digital Content Protection or HDCP for HDMI, which means that your Hi Def signal can be protected when transmitted over High bandwidth such as provided by the ISP's

What this eventually may mean is that cinemas as we know may be on the way to becoming less necessary as you can now enjoy the Hi-Defintion experience from the comfort of your home,as HDMI opens the floodgate of digital content from major motion picture producers. The scenario of downloading the latest movies,direct from the studios, and viewing them on your own Hi-Def monitors, in your own home is not far-fetched.

Because HDMI is not compressed, we can now receive deeper color, higher speeds, crystal clear audio and video signal via a single cable. HDMI supports the the existing standard, enhanced or HI-def video formats (720p, 1080i, and 1080p) and is also backward compatible meaning support is also available for Digital Visual Interface (DVI) which is used on computers and graphics cards. This allows a DVI source to drive a monitor with an HDMI cable and vice versa. With the right equipment, you are able to view movies in Hi Defintion on your PC, provided the cables and converter are present.

Hdmi Licensing LLC, a wholly owned subsidiary of Silicon Image Inc,is responsible for licensing the Specification, educating and promoting the benefits of HDMI to consumers and retailers.

There are some exciting new capabilities under development for HDMI as efforts are geared to supporting new compressed digital audio formats such as Dolby TrueHD and HTS-HD

Higher speeds and deeper colors as support for 30-bit, 36-bit and 48-bit color depths promises to render over one billion colors in unprecedented detail.

Smaller devices, such as HD camcorders and still cameras that demand seamless HDTV connectivity can also benefit as only one connection is now required.

HDMI has made significant inroads into The Personal Computer world as PC related companies are also founders and early Adopters HDMI can be found in products from ATI, Hitachi, Intel, Nvidia, Sony and Toshiba. Most major HDTV manufacturers have incorpaorated HDMI inputs into the latest products and also media PCs, DVD players, DVD recorders, cable and satellite A/V receivers. Expect to see HDMI in game consoles and camcorders in 2006.

It has been noted , by Hdmi Licensing LLC that 300 milliuon makers of consumer electronics and PC products worldwide have adopted HDMI as more than 17 million devices featuring HDMI were shipped in 2005 and 59 million more are expected in 2006.

China accounts for 30 % of the world's household, and 45 mainland Chinese Companies have already adopted HDMI and the number is growing rapidly. China's first HDMI testing facilty was announced in Shenzen,whcih accelerates HDMI in the Chinese market. The Cable and Satellite Broadcast Association of Asia (CASBAAA) has recommended that HDMI be included in every receiver that processes uncompressed Hi-Def signals. In Europe, the European Information and Communications Technology Industry Association (EICTA) mandates that all HDTV's with the HD ready logo must include HDMI inputs.

With all present and future developments, together with the emerging onslaught of High Definition broadcast signals it should be apparent that HDMI is soon to be an essential . that will be definitely need to fully enjoy the digital home theatre experience.

Movie Downloads Using The Net To Get The Movies You Want

If you have a high speed internet connection you have access to a song, movies, books, and a host of other digital entertainment and educational information. But you?re also exposed to some new dangers and opportunities to be taken for a ride.

Music, video, and movie downloads have grown tremendously over the last eight years; moving from free wheeling, and under the licensing radar to not only legal, but incredibly prosperous for those companies with the right business model.

Music Downloads

If you can think of a song you can probably find a site offering to download it for a price, usually somewhere around 99 cents a download. Other sites, such as ++++ offer a membership which includes unlimited downloads.

Given the size of the music files, and the fact that they are usually in an MP3 format, the downloads are typically quick and easy. And they can be played on an iPod or any other standard MP3 player or with an mp3 application such as RealPlayer ? or Windows Media Player. And while iPod dominates the portable player market, companies such as Motorola and Sony offer devices to the consumer. A quick search on FROOGLE shows a wide range of devices at an equally wide range of prices. Of course, the primary factor in the cost is the amount of memory available for storage. The larger the memory, the more expensive the unit is.

Television shows such as ABC?s Lost or other shows will generally take longer to download; anywhere from five to 10 minutes. And of course, the ability to play these programs is more limited.

But even with the greater restrictions, video downloading (music videos, old television programs and other video files is still relatively simple and relatively cheap. Most vendors (iPod, and others) charge anywhere from 99 cents to a couple of dollars to download a single song. Additionally, the smart vendors allow the person downloading the file to play it on at least one other computer.

Unlike music, music videos, and television programs, movies downloads are still relatively awkward. Many require an hour or more to download (if nothing disrupts the process), require a proprietary application to play, and can only be played on your computer. Some will allow the person who downloaded the file to ?register? it on at least two other computers. This can be a little less than cozy unless you have a networked computer and can play the downloaded movie through an entertainment center.

As with music downloads, more and more movie vendors are coming on line every day, offering anything from the 1930?s classics to more current fare including Ultraviolet, Planet of the Apes and the Terminator series.

Prices run the gamut as well. More current movies downloads can cost as much as $19.95, older movies less than ten dollars. Television shows will typically run from $1.50 to $2.00.

As with most things in life, the download technology offers trade offs. Sometimes the amount of time spent downloading the movie is as much time spent simply driving to the video store. The amount of tweaking needed to make a proprietary player work can knock the luster off the ability to see that movie none of the video stores carries.

It all comes back to a saying that has been around for ages: Let the buyer beware. Vendors are going to promise the sky. Rarely will they deliver it, but sometimes they can come close. You have to figure out which one delivers and which ones just say what you want to hear.

Okay so if you really want to harness the power of the internet and movie downloads it is imperative that you use a good provider. By selecting the wrong provider you can be left with slow downloads and even open yourself up to viruses etc. Check out the most popular and highly respected movie download site online at Movie Downloads.

How To Get The Best Out Of Your Projection TV

Projection Television

A projection television can provide consumers with the ultimate television viewing experience they can possibly imagine. With a large screen, a projection television gives consumers the feeling of being amid the action and television viewers are propelled into the fictive dream state: a state that is induced by the crystal clear clarity of the images cast from a projection television screen. Thus, a projection television is a worthwhile investment for consumers seeking the very best in television entertainment and viewing.

If a consumer plans on purchasing a projection television or if they already have a projection television in their home there are some things that they can do to maximize their television viewing experience. First, when the projection screen is placed in the home, the consumer needs to give consideration to where the television is placed. The projection television should not be placed in a location where the windows will be able to cast light on the screen as it will directly affect the viewer?s ability to see images clearly. Instead, the projection television should be situated facing away from any windows if possible or in a location where there will be minimum glare effect.

Along the same lines, keeping the screen of the projection television clean is important if the consumer wants to see images as clearly as possible. Using a cloth sprayed with an appropriate glass cleaner, the consumer can clean the projection television screen with relative ease. The cleaner should not be sprayed directly onto the screen at anytime, as to much moisture may damage some of the working parts of the projection television.
