While my laptop charger has never bugged me, but I always felt strange at times to see a bump in my laptop charger right after it connects to the laptop. I always use to wonder why the charger has a bump and what purpose does it serve?
You normally see these “bumps” on the mouse, keyboard and monitor cables in a typical computer system found in a home or office. You can also find them on power supply wires when a device (like a printer or scanner) uses an external transformer.
It turns out that these bumps are called ferrite bead. It may also be called blocks, core, rings, EMI (electromagnetic interference) filters, or chokes. A ferrite bead has the property of eliminating broadcast signals and prevents energy loss of the same type within the charger. This makes the charger much more effective and helps charge your computer more quickly. Their purpose is to reduce EMI and RFI (radio-frequency interference). These cylinders are responsible for stopping very large deviation of power over supply through the cable and power surges in currents that pass through the cable and prevent ‘choke’ within the wire to make it any further supply the current to the device. The blocking is most effective when it is near the source of the EMI, that’s why you will only find these ferrite beads near the end of the cables.
It also acts as a choke or inductor that blocks high frequency noise in electronic circuits. Ferrite bead employs the dissipation of high frequency currents in a ferrite ceramic to build high frequency noise suppression devices.
The bead is made up of ceramic compounds, derived from iron oxide and/or oxides of other transition metals. It helps to prevent the wire behave on over floating current like aerials. It slips over the cable when the cable is made, or it can be snapped around the cable in two pieces after the cable is made. The bead is encased in plastic — if you cut the plastic, all that you would find inside is a black metal cylinder. This metal wire can possibly serve as an antenna by absorbing or releasing any radiation while passing current around it.
The radiation released by the wires without the bead could cause interference with other electronic objects around them, which act as receivers of this radiation, for instance, causing noise in speakers. This phenomenon’s example can be seen when cell phones interfere with the signal devices such as radios and speakers, producing a recurring noise well known for electronic users.
There was huge excitment once the Blackberry mobile phone was introduced to the shops, since it was a great advance. Alas you still had to use wires to charge it but no more thanks to the Blackberry wireless charger. Three of the most popular wireless chargers available are the Powermat, GEAR4 and Wildcharge. They will charge the Blackberry Pearl, Blackberry Bold and Blackberry Curve mobiles.
Recharging your mobile is simplicity itself. All that’s required is the mat or station you place your phone on and a specifically designed battery cover or back door. It is simple to swap it with the cover that comes as standard with your blackberry. It’s essential you do this as the new cover has a built in receiver.
To start the wireless charging all you have to do is slip on the new back door and put your phone on the wireless charging mat. Job done No wires, no plugs, quick and easy and very 21st century.
The question that may occur to you is can I check it’s working properly? There are small indicator lights or sometimes audible noises included so you know it’s charging. So as soon as your phone is positioned the charging commences. Interestingly, in addition, small magnets are built into the mats so as you go to position your blackberry you feel the magnetic attraction.
This is designed to keep your phone secure, although you should not have a play and hang your wireless charging mat either vertically or at an angle because the magnets aren’t strong enough to hold the phone safely in position.
As an additional plus the wireless charger stops charging once your battery is full. The older plug and wire keeps charging and using electricity until you unplug it. If you’re Blackberry is only partially charged the wireless charger realises and restarts the charging process. So your Blackberry is always primed and ready to go.
As the sales have increased the main manufacturers have organised themselves and standardised the technology with the low power standard up to 5 watts . This means that you’ll be able to look out for Qi logo, which will be on all technology goods meeting the standard. Many experts are predicting that this will herald the start of a new era with the big mobile phone companies incorporating the technology.
Theoretically you could charge up any electrical goods wirelessly as long as they had this integral technology. So your kitchen area will change substantially with work surfaces containing wireless charging technology. It’s almost like sci-fi movies are coming true.
Back in the present the biggest selling blackberry wireless charger is the Powermat. However with the adoption of the agreed new low power standard the big boys such as Apple and Nokia are expected to join the party and produce their own wireless chargers so the future looks very exciting.
Solar Paper world’s slimmest and lightest solar charger for GoPro cameras, Bluetooth speakers, Digital cameras, flashlights, smartphones etc
Solar Paper is the world’s first solar charger that is paper thin, ultra light in weight, pretty flexible solar panel that easily fits between the pages of a notebook or a planner.
Solar energy is nothing but the energy harnessed from sunlight which is available in abundant and just needs to be tapped with appropriate devices.
Solar Charger, is not a new product and there are already many solar chargers available in the market which are really great; however the main problem with even the best of the chargers is that either they are too heavy or too big which makes it difficult to be carried around during day to day activities. Some of them even take a very long time to charge the gadgets.
The major goal behind developing ‘Solar Paper’ was to get a small scale personal solar charger which could charge the gadgets much faster.
Thus, a company known as YOLK, a solar charger startup based in the US, successfully developed ‘Solar Paper’ which claims to be the world’s first thinnest and lightest solar charger. Yolk is the same company which had developed the Solarade portable chargers last year which had an awesome response and a positive review.
Solar Paper is just the size of an iPhone 6 measuring around 19 cm in length and 9 cm in width, and it seems that the charger is able to charge an iPhone 6 in mere 2.5 hours in full sun, which is really amazing because most of the other solar chargers and even a wall charger would take almost double this time to charge an iPhone6.
The Solar Paper is extremely thin, about 1.5 millimeters thick along the length of the panel, and the company claims that the charger is so thin that it can be even placed in between the pages of a notebook and used as a bookmark. On the other hand, it weighs around 120 grams indicating it is light in weight.
The top end of the panel features a USB port that can connect to the gadgets and a LCD screen which displays the overall current charge being passed from the panel to the gadget. This LCD screen would help the user to make out how much energy is being generated by the charger and also user can study how the charger is performing in different atmospheres. Due to the LCD screen this portion of the panel is a bit thicker measuring around 1.1 centimeters; however otherwise the device is pretty slim.
This light weight and thin solar charger can even be draped around the exterior of a backpack thus helping the hikers to gather adequate sun rays and then use this solar energy to charge their gadgets.
Each single unit of the Solar Paper outputs around 2.5 Watts. Besides, the beauty of the product is that the panels have been embedded with magnets which enables users to link together the extra panels depending upon the requirement of their charging. Users can have the Solar Paper charging configured in the multiples of 2.5 W such as 2.5 W, 5 W, 7.5 W and 10 W. One would thus need four panels so as to get 10 W, which is the power required to charge a tablet. The magnetic surfaces also help users to stick them on some metallic surfaces while placing it outdoors.
Solar Paper charger is currently on the global crowd funding platform, Kickstarter and the good news is that it has already surpassed its goal of $50,000 and at the time of writing this article it has crossed $214,415, while the company still has 36 days more to go.
Once the funding rounds comes to an end the company would focus on developing their first batch of Solar Paper and it is expected that the first batch of chargers would be shipped to customers in September this year.
The Solar Paper can be used to charge GoPro, external battery, Bluetooth speaker, Digital camera, double recharging battery charger, flashlight, smartphone and even Tablet just by adding additional panels.
If readers are looking for a super thin solar chargers then they would need to churn out around $69, now, for a basic two panel version that gives a 5W output. For the 7.5 W and 10 W the cost might be a bit more. The retail price would increase after the Kickstarter campaign and is expected to hit $120.

“Whose phone charger is that sticking out of the wall? Oh. It must be Ben’s. Ben always leaves his charger at work. Classic Ben!”
Alas, it’s not Ben’s charger. Hell, it’s not a charger at all. It’s actually a little spy device disguised as a phone charger, capable of sniffing out every key you type on that wireless keyboard on your desk. Oh, and it can send the stuff it picks up straight to the eavesdropper’s phone. Oh! Oh! And it’ll keep working even if you unplug it — it only pretends to turn off.
That little box up top is built by Samy Kamkar (Yeah the same Samy who built the self-titled worm that ravaged MySpace back in the day, and who built that crazy hands-free hacking necklace a few weeks back) who has dubbed it the “KeySweeper”. (Youtube Video)
Before you panic and throw your keyboard in the trash, the good news: this specific device only affects certain wireless keyboards. Most notably, Microsoft-branded wireless keyboards. We’re still trying to dig up a more exhaustive list — but for now, let “Microsoft wireless keyboard” be your caution sign.
In a statement, Microsoft notes that it only affects their 2.4 Ghz (not Bluetooth) keyboards released before July 2011. Even if it’s “only” older keyboards, remember: outside of the gamer crowd, most people don’t update their keyboards very often.
Here’s some of the crazier stuff KeySweeper can do:
■Sniff out keystrokes as you type them.
■If it detects certain keystrokes (like “TopSecretWebsite.com”), it can grab the chunk of text that follows (like your username and password) and send it over SMS to whoever planted the device
■Store keystroke logs on the device itself. These logs can be extracted from the device by hardwired USB, or by putting a second KeySweeper device within range of the first (like, say, an outlet on the other side of the wall).
■When plugged in, it grabs its power from the wall
■When unplugged from the wall by an abnormally suspicious bystander, it looks like it powers down — but it actually just switches to battery power. Logging/sending continues. Naaaasty.
On the upside, most brand-name wireless keyboards sold today use encryption methods that are a bit tougher to crack. Logitech, for example, uses
Samy estimates that each unit would cost $10 to $80 to build, depending on what sort of features you want (ditching the SMS support, for example, brings it down by about $45) — but is quick to note that he’s not actually selling these.
