Power Supply Repair Safety

If you want to check the hot section in a power supply, always use the one hand ‘rule’ so that it would not complete a path for current to flows through your body just in case if you were to accidentally touched a live connection or cable. If you are tired and weak, do not repair any electronic equipment or else you might end up causing more problems for the equipment by replacing a wrong component. Take a break and come back to tackle the problem when you are fresh again.

Always use original part numbers for replacement when dealing with components in the critical section such as the fuse area. If the fuse rating is 3 ampere, then you must replace it with the same value which is 3 ampere. Sometimes a slightly higher ampere such as 3.15 ampere may be acceptable. Do not use a 10 or 15 … Read the rest

CRT Monitors

For CRT, pricing is the clear plus, costing much less than other forms of technology such as LCD or plasma. They also last longer, giving you more shelf life for your money. They can endure lots of heat so don’t expect LCD’s to hold up in extreme heat like a CRT can. So, on the face of it CRT has an advantage or two over other monitor types.

But, CRT image quality is still not good – that is not to say it is bad either – but other forms of monitors are much better. The average CRT monitor is much heavier, and bulkier than their slimmer counterparts. And, CRT monitors should never be left on too long as they can ‘burn’ an image of what is on the screen into the monitor. With today’s ever expanding screen size, CRT’s can never exceed 40 inches, so you will have to … Read the rest

External Laptop Batteries

External laptop batteries are very cheap and can be charged by an external battery charger. A laptop user can make a decision about the chemical that is used for manufacturing these batteries such as Nickel Cadmium or NiCd, Nickel metal hydride or NiMH, Lithium ion or Li-ion batteries.

The price of an external battery may vary from $120 to $200 and these batteries are available on the Internet as well as in the regular market. As computers and other related appliances are becoming cheaper, the prices of laptops are also dropping. This means that more and more people are using laptop and for longer periods. These batteries are ideal for those who want an extended power source for their laptops when they are traveling. An external laptop battery connects to a laptop through an AC adapter plug and usually have two output levels. It consists of an adapter, a chord … Read the rest

Countries May Dive Into Data-Sharing Pacts

“The current legal assistance process can take up to two years, but the agreement will reduce this time period considerably while protecting privacy and enhancing civil liberties,” theĀ U.S. Department of Justice said in a statement.

Countries And Legal Systems

The CLOUD Act comes more than a year after the U.S. Congress authorized entering into agreements with rights-respecting foreign companies that allow access to electronic data for certain criminal investigations. The accord will enter into force after a six-month congressional review and after British Parliament review.

Observers say the agreement updates the two countries’ law enforcement capabilities in a world of fast-changing technology and exploding amounts of data.

“In the broader sense, this agreement represents progress towards putting in place the new types of agreements that are needed to manage legitimate issues, like cross-border data flows,” says Nigel Cory, associate director for trade policy at theĀ Information Technology and Innovation

Sheet Fed Scanner

Small Sheet-fed scanners are available for as little as $200. Sheet-fed scanners are ideal for the business cards, handwritten notes, letters, and Photographs. Sheet-fed scanner allows scanning, faxing, and copying. There are many ways in which the documents can be feed into the scanner, By resting the sheet-fed scanner on its sides of the main body you can feed the document from different positions: when resting on the base plate it allows a horizontal feed-in and feed-out of the document; when on the first inclined side the inclined is in such a way that it allows a top feed-in and bottom feed-out; and when resting on the second inclined side, that allows an inclined bottom feed-in and top feed-out. Most inexpensive sheet-fed scanners are designed for black-and-white work, although newer models can handle color. You can find sheet-fed scanners that plug into your computer’s port. Disadvantages of sheet-fed scanners are

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 … Read the rest

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 … Read the rest

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 … Read the rest

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.

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 … Read the rest
