Gaming Computers

Customize your computer

A gaming computer ideal for customizing consists of basic components like the power supply, case, and the motherboard. They are ideal for the gamer who likes to add more components based on their gaming preference since they are easy to upgrade and troubleshoot to match the gameplay requirements for different kinds of games.

Buy prebuilt

A prebuilt gaming computer is already assembled. It includes the CPU, monitor, input devices, and the sound, network, and graphics cards. Most have unique CPU designs like colored cases and lighted towers so you can match them with your ideal gaming environment.

Check for ports

When shopping for gaming computers, check on their available ports for plug-and-play purposes. Look for one that has a lot of USB 2.0 ports to ensure compatibility with other different devices and gaming peripherals. You should also check for the connectors on your game controller to see if they are compatible with your computer and its available ports.

Check for cooling

Your gaming computer should have enough ventilation to endure long hours of gaming. Remember that gaming can easily heat up the insides of the computer, which can damage circuitry. Make sure it has vents and powerful fans at the sides and back.

Hand Held Metal Detector

This is such a bad news not only for the general public but also for the officials whose task is to make sure the peace and order reign in the area of responsibilities. The growing menace of the society poses a big problem that is not at all becoming easy to solve. With this in mind, there has to be creative and smarter solutions in approaching the situations.

One of the things that can be done is to thoroughly implement standard security measures. These measures are usually sufficient if only security guards or anyone tasked to go about these measures would only be patient enough to go through each step.

Sometimes because nothing bad is happening, everyone becomes lax including the people who should be always keen on watching suspicious things and behaviors. Only when the news reports of failed bombings or successful terrorist operations do everyone go back to being always on their toes. It is about time that people take seriously the call to be vigilant.

Second is to have hand held metal detectors in all establishments. Metals are usually the main driving force behind devices so detecting a metal device early on can save everyone of a brewing future trouble. Personnel at the doors should not be scared to use the hand held metal detector to anyone who enters even if there are VIP’s.

It can be a hassle but it is okay to have a bit hassle than to have none and ending up blaming the fact that the person who was able to infiltrate a said building or establishment just got in without any trouble. Though there are many possible hiding places of metal pieces, a person who knows how to use a hand held metal director would have an idea where to more or less look for metal stuff.

These two things can certainly have an impact in security and to think these are but basic measures that can be applied by anyone or anywhere. Make sure then to do the two things above to make yourself secure during perilous times like what we are experiencing now.

Speedometer Calibration

The driver may not notice how fast the vehicle is going when sitting behind the wheel and the only indicator will be the speedometer located a few inches below the windshield. There are two types of speedometers. The mechanical and the electronic version.

The mechanical speedometer works using a cable, a rotating flexible shaft and a magnet. After calibrating and combining these three components, the speed of the car will continue to increase as one continues to step on the gas.

The electronic version also uses a magnet. The only difference is that in order for this to work, the entire system needs a computer. Once this is calibrated, it will be able to tell how fast the vehicle is moving.

Most of the cars use the electronic version but those who like to drive something like a 1956 Mustang will surely be able to reminisce the good old days when the mechanical speedometer made man and machine work together.

Unfortunately, driving more than a hundred miles per hour in the city or even on the freeway with the calibrated speedometer will only get the driver in trouble. For safety reasons, the police will most likely pull over the driver and issue a ticket.

This should serve as a lesson to the one behind the wheel because most car accidents are caused by over speeding or drinking under the influence that causes damage to property and may take someone’s life.

One ticket is OK but repeated offenses will make it more expensive to get insurance for the vehicle. At worse, no one will want to insure the individual given the reckless history that is a liability to the insurance company.

The best thing to do then with the calibrated speedometer will still be to follow the traffic rules especially the speed limits. This varies on city and highway driving but regardless where one is, the right thing to do will be to abide by it.

Agilent Technologies

There are a lot of spectrum analyzers in the market. If the person is having a hard time thinking of what brand to try, then perhaps using something from Agilent technologies can help make that happen.

The company has large units such as the E4447A that measures complex RF and millimeter waves up from 42.98 Ghz to 325 Ghz. The price for one of these things is expensive and fetches for more than $60,000 a piece.

If the individual doesn’t have the budget, then perhaps something cheaper will suffice such as the 8560EC portable spectrum analyzer that can only measure until 2.9 Ghz, which is half the price of the bigger unit.

The E4411B-BAS ESA-L Basic is another interesting model. It can measure from 9 to 1.5Ghz and is very lightweight. This will only cost $8,000 and will work well for those who are just starting out.

Some stores sell these products but if the person wants other options, then it will be a good idea to visit the company website and select from the models available until the right one is found.

The company accepts orders online and after paying for this using one’s credit card, this will be delivered within 6 to 8 weeks that comes with a manual and a warranty.

If the customer has any problems with the product, there is a customer service hotline that the person can call so that a representative could offer assistance.

There are those who are still hesitant about the price of a brand new spectrum analyzer. If that is the case, then the company can give a better deal by offering second hand units that have been returned or this can be traded for something the owner might have that is no longer useful.

There are other places where the individual can also get a second hand unit from Agilent. There is eBay and other auctions sites as well as junkyards that may have one lying around that will need some repair.

Spectrum analyzers can be used in checking the sound system in the entertainment room or in the car. The samples mentioned can be used either for work or for other functions.

Iomega Zip Drive

Zip drives worked in almost exactly the same way as a floppy disk except they were physically bigger and provided a much higher data transfer rate than home users had ever seen before in an “external” data storage device. The biggest problem with Zip drives is that although they were similar to floppy disks you still needed a separate Zip drive to read or write to these disks which in turn meant more expense for home users. Also there was a rival technology called the LS-120 or SuperDisk that found favour with many computer manufacturers (ironically enough the Zip drive long outlived the LS-120 in terms of popularity and usefulness) so the Zip drive faced an uphill struggle from it’s introduction to an eager computer market.

The Zip drive was/is available in a few different flavors. There were parallel, SCSI, USB and IDE Zip drives available on the market at one stage. This meant that regardless of what type of computer you had you’d be able to find a Zip drive with a compatible interface. This meant that both Mac and PC users tended to love the Zip drive although most Mac users tended to favor the Zips bigger SCSI brother – the Jaz drive… that however is the topic for another article for another day.

Alas for all their ingenuity the Zip drive has become all but obsolete. The current growth in hard drive storage capacities has meant that any storage device offering less than 10GB – 20GB of storage space is all but ignored as a useful backup device. Any computer user reading this who has ever owned a Zip drive will probably feel the same sense of nostalgia I felt when writing it. The Zip drive was incredibly revolutionary in it’s day and paved the way for a real boom in data backup technology for homes and small businesses. RIP Zip drive…. you shall be missed.

Calibration Technician

In fact, ISO9000 and other standards state that the maximum period between calibration and re-calibration should at least be once every two years or more regularly if instrument degradation is becoming more and more noticeable during specified period. But, in order to ensure the quality of the measurement, many companies and users opt to implement annual calibrations.

Since calibration is required by national and international standards–usually agencies that require a specific system of periodic calibration and maintenance to avoid destructive testing–companies must hire a person that would oversee the calibration process–the calibration technician.

Expected to calibrate, adjust, and repair test measurement and diagnostic equipment, calibration technicians are also required to follow all 17025 and/or standard metrology, procedures, polices and practices. Calibration technicians are also expected to calibrate mechanical, electrical, and optical measuring instruments while preparing written calibration procedures and ensure their proper implementation as well as oversee calibration activities within the department. Aside from these, calibration technicians are expected to:

  • Suggest and create changes to the usual calibration procedures
  • Able to provide calibration certificate data to Metrology Manager
  • Know when to notify the Calibration manager if an out of tolerance condition is discovered
  • Give an off site support for the customers
  • Able to meet the statutory and regulatory requirements like having the ability to lift 50lbs unassisted and the like.
  • Aware when to stop working and inform proper management upon observing a non-conformance in the procedure
  • Have calibration certification or equivalent experience
  • Understand and comply with management policy and adhere to its quality policy.

To be able to become a calibration technician, a university degree in a related technical discipline complemented with a background in Mathematics and Physics is a must. Usually, those who have excellent written and verbal communication skills have more advantage over those who don’t.

Aside from that, most companies also require their calibration technician to gain advanced understanding of related, complex concepts and procedures.

Large Format Scanner

There are a couple of very good reasons starting with

  • Wanting to gain a global reach via e-mail and the Web for your design work or art
  • Would save money from being able to convert hand drawn plans to CAD format using vectorisation software
  • Would like to archive important large format documents
  • Want to get plan drawings into digital format for a specific project

Whatever the reason and there are many…the problem has always been affordability.

Thanks Goodness that has now changed with the advent of the new Australian Deskan 6.00, a mature 2nd generation scanner designs that puts in-house large format colour and mono scanning at your fingertips for about $6.00 per day.

The Deskan 6 Large Format Scanner finally is the answer to smaller business and individuals who need a high quality solution to get plans, maps, art and even fabric into the computer.

With a scanning resolution of up to 600 DPI and the capacity to scan in either 24 bit colour, greyscale or black and white from wide format documents even larger than “E” or “A0” size, this rugged and reliable Australian innovation offers the same set of features found in traditional wide format roller scanners, but at a quarter of the normal price.

The only real compromise is scanning speed.

However, with the capacity of realistically scanning up to 90x E-size (A0) wide format colour documents at the industry standard resolution of 200 dpi and up to 150 similar size documents in black and white in an eight hour shift, it would only be the most demanding commercial imaging service providers and large government organisations who may find this compromise unsuitable.

Consider this. A standard wide format colour roller scanner of around $15,000 works out to a monthly lease repayment of approximately $600.00, an expense that can hardly be justified by most smaller organisations.

On the other hand, the Deskan 6 comes to only US$4500.00 which includes international shipping to the USA, Canada or the UK. This means you can enjoy all the benefits of an in-house wide format colour scanner for only $175 per month which works out to less than $6.00 per day.

If you cannot benefit from having a colour wide format scanner at $6.00 per day, you don’t need one.

Let’s have a closer look at some of the organisations that may benefit from investing in the Deskan 6 Large Format scanner.

Instead of relying on expensive courier services, Architects, landscapers and other artists are instantly empowered to serve a much wider geographic client base by being able to scan and e-mail their freehand drawings or art. What used to take days can now be on the client’s desktop for approval with in a matter of minutes.

Manufacturing and maintenance divisions can now provide key employees with controlled and instant online access to collections of plan drawings or other information contained in wide format documents. This reduces downtime and increases productivity to the extent of having become a no-brainer to organisations who wish to stay competitive.

Manufacturing engineers involved in reverse engineering of components now have a low cost and viable option for the scanning and vectorisation of 2.5d components.

Other individuals who may benefit include those who need to create CAD format stencils and templates for electronic embroidering, vinyl sign or laser component cutting, custom auto detailers and artists, fabric and carpet pattern designers, smaller photocopy shops and printing businesses etc.

For those who need more information and would like to see an online video presentation, please do not hesitate to check out this amazing new innovation.

With a solid involvement in computer hardware stemming from the early 80s, and specialising in the conversion of hardcopy to searchable electronic information for the last 13 years, I have always been motivated to bring the latest innovations to clients who could benefit from digital imaging.

Multiple Monitors

Then I started using two screens on the job. You know, it’s been very accommodating. Now I’m wishing I had one or two more at home. If you’re someone that spends a couple hours a week on your computer mainly for corresponding or paying bills, then having one monitor is probably enough.

If you spend any amount of time at home studying or writing or compiling any kind of media – like your family pictures, videos, and music – two monitors (or more) will not only save you time, it actually relieves tension on your eyeballs.

No, I don’t actually have any “facts” to back that eyeball statement, but from my own experience, I feel less tired using my two LCD screens at work then my one LCD at home. The advantages keep growing as I use them. Organizing research and pages are so much easier. And you get to move your head around diminishing that inevitable cursed kink in your neck or back.

As an editor, it’s been fantastic to have one screen keeping notes and one screen to do work on. There’s so much more space to work with. It’s like the difference between keeping your books and papers piled on a tiny little desk or having a nice big drafting table.

For businesses, having a couple screens or more can make your work speedier, more organized and accessible, and enable you to easily handle several projects at once. For CEOs and busy managers, supervisors, etc., the multitasking advantages will astound you. Your employees will literally sing halleluiah with indulgent utility and convenience.

For gamers, well, most of you already understand the awesome output of two or more screens. Imagine having four to six or more, all combining into one picture! Holy big picture, Batman!

Yeah, it’d be great to have, you say, but I’m no technogeek. Neither am I, but there are a couple different and mercifully easy approaches to take.

Depending on your PC system, you may be able to plug more than one monitor into the back if you already have more than one port. Your computer has settings in your control panel to add monitors once they are plugged in.

You will probably have to add ports to your PC, which is usually fairly simple and affordable to do. There are adapters, ExpressCards, docking stations, and video cards.

The adapter I’m familiar with uses your USB port to add one additional VGA port to your PC or laptop. This option is super simple and handy for all users.

For you laptop owners, there are ExpressCards or PCMCIA cards that add a port and can be expanded with additional cables for even more ports.

Docking stations are pretty simple, too. They can also have added functions, depending on the station. Stuff like audio connections for your stereo, Ethernet and USB ports, as well as the video ports you’re after.

For those who feel more confident in their technical abilities, you can physically add video cards to your PC box. You can find cards that have two or more added ports on them. These add to your existing VGA or DVI port.

If you want to go all out and get a display system, which would be the easiest, there are complete units that include two to eight screens with awesome software to manage these screens. For people who have a lot going on, like traders, busy corporates, gamers, stock brokers, internet gurus, etc., these systems are worth every penny.

I predict these kinds of setups will eventually replace or be integrated into our TV systems. They probably already are in some circles. I’m not in that circle, but I’m learning. And it isn’t as hard as I thought it would be.

The advantages of having more than one monitor makes sense to me now. Truthfully, I get tired of looking at my monitor. I’d much prefer a book or hard copy in my hands. I can’t wait until that invention hits the market. A book-like computer? Wouldn’t that be awesome?

Until then, having two screens is the closest I can get to having pages. Maybe I’ll even try three.

Laptop Disassembly Guide

Search on the net for service manuals some are free and other cost around 6$ . Not find your model ? download some free service manual from different brands and read them many steps are the same in laptop disassembly. But i do recommended to find the manual that fit your laptop because you may need to know the part number of the defective part to change it.

Now you have to prepare a clean working area with small box for the different parts and their screws, and maybe a pen and a paper to remember particular step.

To disassemble the computer, you need the tools below:

  • Wrist ground strap and conductive mat for preventing electrostatic discharge
  • Small Phillips screw driver
  • Flat head screw driver
  • Hexagonal driver
  • Tweezers

NOTE : The screws for the different components vary in size. During the disassembly process, group the screws with the corresponding components to avoid mismatch when putting back the components.
When you remove the stripe cover, please be careful not to scrape the cover.

In most of laptop you can actually access by the base to these bays :

  • battery
  • memory
  • hard disk

Remove them all, to remove the optical disk just release the screw securing the optical disk module,push the ODD module using a screwdriver and remove the ODD module from the main unit.

After that look on the keyboard area to find how to remove the keyboard for example with an Acer aspire 5100, you have to remove the middle cover from the edge of the middle cover and carefully detach the middle cover, then you just have to release the two screws securing the keyboard plate and carefully detach the keyboard plate from the edge of the keyboard plate finish by release the keyboard FFC lock carefully because it is fragile. Then remove the keyboard plate.

After that you can either disassembly the lcd module or try to access the motherboard.

For the LCD module carefully disconnect the LCD cable and any other cable that you can see, release any screws holding the LCD module on the bottom side of the main unit, release any other screws securing the LCD hinges on the main unit, then detach the LCD module from the main unit.

Wonders of Calibration Weight

One of the greatest discoveries in the field of measurement is calibration. Known as the process of establishing a relationship between content and a measurement signal from any instrument, calibration has become popular especially in the world of research and laboratories worldwide. Some experts say that the relationship resulted from calibration does not necessarily be linear in many instances.

In fact, the correct number of calibrators that are used is quite dependent on the supposed shape of the measurement in response to its function.

Calibrators are also necessary in order to define the signal response to changes in the content of the specimens over the defined analytical measurement range. Here, the calibrator materials are assigned to fit a specific measurement system, thus, taking into account the differences between the two variables.

Aside from establishing a certain relationship between a content and a measurement signal, calibration is also helpful in determining the accuracy of the end results especially those used by method manufacturers or clinical laboratories.

For scientific purposes, the methods of calibration can independently validate the accuracy of the any calibration process, thus, maintaining a the traceability to test the best available reference materials or methods there are.

One of the interesting topics to discuss about calibration is the calibration weight. Tracing back to 1838, a scientist named Troemner was able to discover and provide a wide and extensive selection of calibration weights and mass standards.

Due to the reliability and credibility of his discoveries, the name “Troemner” is now synonymous to the ISO 9001 registered company that is one of the leading suppliers of calibration weights and mass standards across the globe.

Manufacturing and certifying calibration weights and mass standards to meet or even exceed the highest tolerance standards of the National Institute of Standards & Technology (NIST), the American Society for Testing & Materials (ASTM), the International Organization of Legal Metrology (OIML) and ISO 17025, the company aims to produce quality calibration weights and standards that would provide the best option and alternative to as many clients as possible.

If you’re looking for a calibration weight, you must be able to identify first the qualities and the characteristics of a good calibration weight:

  • It should favor calibration of balances with an external certified calibration mass.
  • It should at least feature balance with internal motorized feature like internal calibration and external calibration because these are vital for recalibration or certification.
  • It must be able to offers precision weighing balance that allows you to calibrate the balance yourself without requiring the services of an outside calibration firm.
