Cool Tools: Satechi Slim Surge Protector

If you are sick and tired of electrical surges screwing up your gadgets and devices connected to a power outlet, then here is something that you might want to consider. The Satechi Slim Surge Protector is said to come with 2.1 Amps of juice for each port and consists of 5 protected power outlets. It currently retails for a highly affordable $15.99 each, and with 2.1 amps of power, it can charge just about the majority of power hungry devices out there in the market, ranging from the new iPad to the Amazon Kindle Fire, iPhone 4S, and Samsung Galaxy S3 amongst others.

Capable of protecting up to 5 devices from electrical spikes and surges, making sure that your collection of expensive electronic equipment and valuable data will remain safe at all times, there is also the inclusion of the Safety Shutdown Technology that relies on thermal fuses in order to power off the user’s system so that it will offer protection against fire and other damage just in case a power spike occurs. The presence of a green LED indicator that lights up will let you know that your equipment is being protected.

8 Best Tips To Increase Windows Laptop Battery Backup Time

Technix: 8 Best Tips To Increase Windows Laptop Battery Backup Time

When we buy a laptop, then we do focus on some of the parameters like RAM, Hard Drive capacity, Graphics card, Cache Memory and few other features. One of the most important features about the laptop, which we usually forget to consider, is the battery backup. For the first year of usage you will notice that the battery backup is adequate as compared to the other laptops around you (or as promised to you by the seller), but then it starts degrading suddenly and then the only option with which you are left is to change the battery.

6-Cell Li-ion Battery is the most common battery used in most of the laptops. There are certain tips with the help of which you can take care of the battery life and make it durable, please do take care of all the tips mentioned below:-

  1. Never ever put your laptop on your bed while using it, this is one of the major problems for the decrement in the life of laptop battery. When you put your laptop battery on your bed mattress then it blocks the heating vents of your laptops and all the area of that mattress starts heating up along with the laptop making it a hotter base for you laptop. Thus for the cooling of your laptop, motherboard increases the speed of the cooling fan of your laptop which in return starts eating up your battery backup.
  2. Try to put your battery away from high temperature. Your laptop battery loses its durability if it is kept consistently under high temperature. If you have got 2 batteries for your laptop then always keep the other battery wrapped up in a plastic under a cold environment and make sure that the other battery has been discharged up to 50 percent.
  3. Never ever let the battery backup go below 15 percent. You must have heard people saying that once must fully discharge the battery and then charge it again to increase its life, but that is not completely true. This tip will work only when you have not discharged the battery below 15 percent; if it goes below 15 percent it will put high stress on the battery which may permanently hamper it.
  4. Never unplug your laptop battery in between a charging cycle. This simply means that never unplug the battery while it is getting charged and not reached its 100 percent (or I should say unless one cycle is complete).
  5. Do not remove the battery while using your laptop. I have seen people with the habit of removing the battery from their laptop when it gets plugged in to the external supply. If there is an electricity supply cutoff then all the data will be lost and believe me there will be high chance that your hard disk may crash (depends on how older your laptop is?). Now if your laptop has a problem of overheating (which happens due to the accumulation of dust into the heat vents blocking heat flow from your laptop to outside), then it advisable to remove the battery if laptop body temperature goes above 60 degree Celsius.
  6. Never overcharge your battery. Please do not let your laptop be plugged in even when you battery has been fully charged. Doing so will decrease the charge capacity of your battery or I should say it will reduce the backup time of your laptop. Once your laptop gets fully charged remove the power chord from the laptop and use the laptop on the battery back until it reaches it’s 15 percent capacity, then plug that power chord again and do not unplug it until it is fully charged.
  7. Things to remember to increase the backup-time while using your laptop on battery. If you using your laptop on backup and an immediate power supply is not nearby then try to keep the brightness at low as possible, this will really help a lot as brightness is main source of drawing the battery out. Apart from this, try to switch off the Wi-Fi, Bluetooth (which are nowadays switched on from the same switch on your laptop) and all the unnecessary processes which are still running on your system. Let me explain this with an example of a situation, if you are using internet through a Wifi router and you are writing certain application and suddenly electricity cuts-off, then you can do the following; Lower the brightness, turn off your Bluetooth and Wifi, deactivate all the firewalls and anti-virus installed on your system (as now you are not connected to internet), Mute the speaker and try your best not to play any media file.
    Do all this and then see the difference, I can guarantee you that your battery backup will be increased by 50%.
    From time to time keep on defragmenting your hard-disk, it will arrange data efficiently thus reducing the power used by hard drive, if you have any other hard drive connected through USB then please remove it and then empty the CD\DVD ROM.

  8. Power Options, select these options as per your requirements, if you don’t have much idea about it then select the default package for maximum batter as specified in the screenshot above. It will be wiser to put the laptop into hibernate mode rather than sleep mode, as in the hibernate mode OS will pause all the operations and will completely shut down the system whereas in the sleep mode, only hard disk will be turned off and touchpad with other peripherals will be active to get any command and then wakeup the system from its sleep mode.

New Digital Conversion Devices

Everything Old Is New Again

By FARHAD MANJOO

REMEMBER the paperless office, that dream of perfect organization that was peddled by tech companies years ago as a way to sell computers?

The dream may still be elusive, but tech marketers knew what they were doing when they decided that paperlessness would appeal to customers. Whether at home or at the office, physical documents are a pain to keep straight. They take time to organize, they take up space, they can’t be searched and they’re easily lost or destroyed.

And it’s not just paper documents: everything created before digital media can add to the problem. The average American household has about 3,000 non-digital photographs and slides squirreled away in closets, according to ScanCafe, a photo-scanning service. And then there are all those books, cassettes and videotapes.

The last time my wife and I moved, we spent at least half our time packing and lifting books. E-readers may be revolutionizing the publishing industry, but their ramifications for the moving business, not to mention chiropractors, will probably be just as significant.

Because hardly anyone wants to throw away that old stuff, the solution is to convert all those snapshots, videos, music, books and documents to more portable, compact and durable digital versions.

Recently, I’ve been testing conversion devices and services, and results have been mixed. I found that a few conversion systems work marvelously, but that transforming one’s old stuff into new stuff can be a painful process.

Of all the media that clogs your house, old paperwork may be the easiest to tackle. All you need is a scanner to turn the documents into digital files.

One economical option is the flatbed scanner, which usually costs less than $80, but beware of the low price. A flatbed requires laying each sheet of paper face down on the scanning eye and waiting 10 to 20 seconds while it is transferred to your computer. Unless longevity runs in your family, don’t bother.

A better option is a sheet-feeding scanner, which allows you to insert a stack of paper. The best of these is the Fujitsu ScanSnap S1500, which I found to be a dream to use. It is about as big as a shoebox and can hold 50 sheets of paper in its scanning tray; press the button and the machine will scan up to 20 pages a minute on both sides.

The S1500 comes in two similar models, one for Windows PCs and one for Macs, and each will convert your documents into searchable PDFs. After a few weekends with this scanner, you can throw away your file cabinet. The only downside is the price: at about $400, the S1500 is much more expensive than more pedestrian scanners. But if you’re drowning in paper, you may find it is a lifeline worth the price.

I had a much harder time turning my movies and music into digital files. There are several gadgets that promise to do this, but I lost many hours of my life wrestling with them. To convert my cassette tapes, I tried the Tape 2 PC, made by Ion Audio, and the Tape 2 USB II, made by Grace Digital Audio, each of which sells for $120. Then there is Ion Audio’s Quick Play Flash, a $70 unit that converts vinyl records to digital files. And I tested the VHS to DVD 5.0 Deluxe, an $80 device by Honestech that connects your VCR to your computer, allowing you to turn videotapes into DVDs. All of these were easy to set up and operate. The Quick Play Flash, in particular, was a breeze because it transforms vinyl albums into digital files without connecting to a computer: you plug in a USB thumb drive to save your music. All the devices also delivered conversions that were relatively faithful to the original; there was some degradation in the conversion process, but the resulting sounds and pictures were not bad.

Yet every video- and music-conversion machine I tested suffered from one major, nearly fatal flaw: they took forever to work. That’s because they operate in real time. To convert a 60-minute cassette tape, you must play the tape for a full 60 minutes while your computer records the music. The same is true of the conversion processes for vinyl and videotapes.

For most people, real-time conversion is not realistic. My wife has a collection of about 150 cassette tapes that she saved from her high school years. If I spent 10 hours every weekend trying to turn her collection of old R.E.M., U2 and Tori Amos tapes into MP3s, it would take me nearly four months to finish. If your music collection runs into the thousands and you want to do real-time conversion, you had better quit reading this and get started right now.

A more sensible alternative is to send it away and have the professionals do it. Many such services are available for photographs, videos and music. I tried two that specialize in photographs and movies, and found both delightful.

The services, ScanCafe of Burlingame, Calif., and DigMyPics of Gilbert, Ariz., have many things in common. They accept almost any photograph or video format you can throw at them: slides, negatives, snapshots, videotapes and even Super 8 movie film. And they not only scan your images, but also employ technicians to correct flaws by balancing colors, removing scratches and undoing red eye.

The turnaround for each is roughly similar. DigMyPics estimates that it takes about two weeks to scan a typical order of 1,000 snapshots; ScanCafe requires about three weeks. And both services offer a nice bonus that saves you the trouble of reviewing your snapshots one by one before you send them in: after they’ve scanned your pictures, you can check your images quickly by scrolling through them online and deciding which ones you do not want. Neither firm will charge for scanning the discarded images, unless you discard more than 20 percent of the total pictures. The major difference between the two services is cost. DigMyPics conducts all its operations in the United States, while ScanCafe outsources part of its scanning and editing to Bangalore, India. Because it saves on labor costs, ScanCafe is significantly cheaper than DigMyPics and other services, charging 29 cents an image for standard snapshots. At DigMyPics, the price is 39 cents, so if you are scanning 1,000 pictures, ScanCafe will save you $100.

Is it safe to ship your photographs and movies to a scanning service? In 2008, a laptop at the DigMyPics plant exploded, sparking a fire that destroyed the building and many customers’ images. Annette Crossen, who owns the business with her husband, Scott, said that the company has since rebuilt its operations, and among other precautions, the plant is now under constant surveillance and has more-advanced fire-protection systems. If customer pictures are damaged or lost, DigMyPics offers restitution up to $100. Naren Dubey, the chief executive of ScanCafe, said that his firm ships customers’ pictures to India in durable containers that are resistant to damage and monitored against theft. And ScanCafe offers up to $1,000 in restitution in case of damage or loss. “We’ve never had to pay out that guarantee,” Mr. Dubey said.

Eneloop Rechargeable Batteries

Cool tools: Eneloop Rechargeable Batteries

eneloop.jpeg

No doubt, the best batteries I've used are Sanyo's Eneloop cells. They're NiMH but the self-discharge problem is pretty well licked, and Sanyo are the ones who solved the problem.

Eneloops are still the best, but there are more makers now of LSD (Low Self-Discharge) NiMH cells. Usually marketed as "ready to use", their initial charge should still be available at time of purchase.

Sanyo has a fairly broad range of chargers available to go with these things, of which I have a couple. But to really get the most from my cells, I use the LaCrosse Technology BC700 Alpha Power charger. A very good combination for me.

External USB Batteries

From Cool Tools: New Trent External USB Batteries

I have used a New Trent IMP500 external USB battery for the last two imageyears, mostly in the backcountry, to keep multiple devices charged (you need to make sure you have adapter tips or a short cable for each type of device) and am impressed with its capacity and durability. These batteries work when you need them to work.

New Trent has consistently made the most powerful and reliable external USB batteries for USB-devices like the iPhone. Look at the New Trent website to decide which product is right for you, then look at the reviews on Amazon for confirmation of my first sentence.

The newest battery, IMP1000, has 11,000 mAH capacity, about 5-6 recharges for an iPhone 4. Before I bought my IMP500 I researched extensively before buying. Since then I have used this battery under extreme conditions for the last two years, and am more than satisfied.
