A wireless mouse without batteries

The independence of the cables is something that many users would not hesitate for a second to claim, but despite the increased autonomy that the batteries have been recorded in recent times, eventually leaving us at a critical time. It is not the first time we heard about a wireless mouse that requires no batteries, but the good news here is that the people of Genius has launched the DX-ECO BlueEye Mouse . How long do you need to load? Only three minutes.

Not having to deal with cables has great appeal, not to mention the aesthetic benefits that occur between certain computers. However, a golden rule is that wireless devices will know when the batteries have run out at exactly the time when you need to use them. But if the idea of ​​a battery-free wireless mouse grabs your attention, here's a different one.

This is the DX-ECO BlueEye Genius Mouse . You can choose the resolution between 800 and 1600 dpi, has a total of seven buttons, and uses a USB receiver peak, so you will not fight looking for a special position for the receiver (plug in a USB port front is certainly ideal but connected to a USB extender is also somewhat viable). It has an operating range of fifteen feet, and the recharge is through micro-USB cable included. The DX-ECO Mouse BlueEye only requires a charge time of three minutes, thanks to a so-called "golden capacitor" built-in mouse. This capacitor provides a maximum of one hundred thousand recharges , a number well above the amount of recharges batteries.

For 31 euros
The price is $ 40 U.S. (31 €), a reasonable sum. The user must not constantly recharge or have spare batteries installed ready when they run out. But more important is the recharge time. There are only three minutes, so you can go to steal something from the kitchen to chew or comply with a typical "biological commitment," and find the mouse fully charged when you return to your computer. When using a USB receiver there should be no compatibility issues, but does not mention support for Linux.

The iPad can be reached by March 3

Well, it seems that is beginning to be more specific about the iPad3 . As reported in Bloomberg, the new Apple device will be announced in March, and will, among other improvements, with a new quad-core processor .

According to three different sources, the device would already be in production and most of the initial units to be fabricated in February, just in time for a release just a month later. The tablets come from Foxconn , a leading provider of Apple in China, and the factory would already be working around the clock, before the "crisis" will suffer during the upcoming Chinese New Year celebration.

In terms of performance and features, managed by Bloomberg sources are not too specific, but do offer important clues. For one thing, the screen will have a much higher definition than the current iPhone. In fact, you have many more pixels than HD TVs than there currently on the market.

According to one of the experts consulted, "the new screen pixels are so small that it seems that the images are printed on it."

Extraordinary power
There is also talk of a quad core, that is, four cores , while the current standard, with one exception of Asus, is the dual core. The processor of the new iPad would give him extraordinary power . This characteristic, along with a new graphics processor, the videos would be opened "almost instantly".

Another novelty is that the new iPhone would be compatible with LTE , the next step in 3G mobile and begin to unfold in the coming years. It is curious that Apple chooses to incorporate LTE in tablet rather than the iPhone. The reason, says Bloomberg, lies in the battery. The iPhone has a bigger battery and more capable than the iPhone. And LTE is a technology that needs more energy than the current 3G.

Alienware X51, the computer console format

Anyone who follows closely the evolution of hardware components is well known that not only are becoming more powerful, but also getting smaller. The introduction of reduced size format has opened the door to countless projects of "modding", but also finished products and ready to use. Alienware has led to the end to some of its settings for laptops, but when you see the X51 , the first thought is that it is a console.

On several occasions I thought that if he were to pose my paws on an Xbox 360 , the first thing I do is install your hardware in a computer casing. No need to remember the many problems that Microsoft's console suffered at the hands of poor cooling, let alone the famous "Red Ring of Death" , courtesy of welds of poor quality, among other things. For now, Xbox 360 is not within my planned purchases, but the format encouraged both my ideas and those of many enthusiasts. Some of them have been modified extensively to the console, but others decided to work from a similar size with the aim of installing computer hardware. The format Mini-ITX has been a blessing, and there are motherboards you can install some components are very powerful.

On the other hand, you can use a ready-to-use alternative systems such as the X51 Alienware recently introduced. Alienware X51 dimensions are 343 mm in its upper part, by 95 mm wide and 318 mm deep, slightly larger than the first Xbox 360 format (309 by 83 by 258 mm). Your configuration may have some modifications according to the budget of the user. You may opt for a Core i3-2120, a Core i5-2320, or a Core i7-2600 (without the denomación K). Available graphics processors are the Geforce GT 545 Geforce GTX or 555. You can receive a maximum of up to 8 GB of DDR3 RAM and has a healthy repertoire of ports, among which are USB 2.0 (6), USB 3.0 (2), HDMI and optical audio outputs. The Alienware X51 is available with a one terabyte hard drive (I imagine that the user can install larger units on their own, even externally), Wireless-N card, and either a conventional DVD recorder, or a unit "combo" with Blu-ray.

From 543 euros
The price in the United States of Alienware X51 starts at $ 699 (543 €), amounting to $ 1,149 (893 €) at the highest setting. The amount may seem a bit high, especially if we consider that the user must also take over the mouse, keyboard, and of course the screen, but the assembled solutions are always attractive to a lot of users. On the other hand, I know that readers of NeoTeo have more sympathy for arming their own monsters that are smaller, and point to a format not bigger than a console would be a stunning project.

The 'strawberry tree': a public mobile charger solar powered

You're outside, away from home, desperate because the battery of your mobile phone is empty and you have several pending calls. The citizens of Belgrade and need not worry: you can load it for free on the street with a device that works with solar energy.

What mystery Belgrade street store? Host a 'Strawberry Tree' ( strawberry tree ), a brainchild of a group of young people who designed and built a public charger mobile phones, tablets, MP3 players, cameras and other portable devices powered by solar energy.

The invention was awarded last year in the competition in Brussels 'EU Sustainable Energy Europe' on the reduction of public consumption of energy, and has achieved a number of national awards.

"Our goal was to bring renewable energy to all people, closer to all, "said Milos Milisavljevic, the main inventor of the 'Strawberry Tree', an energetic and ambitious student of electrical engineering 22 years .

The operation of the system sounds simple. "The sun that reaches us is converted into solar panels into electricity, which passes through the 'strawberry tree' and enters the cell, "he explains.

"The energy that is generated during the day and not eaten, is stored in the storage battery so the system can work well at night , when it is cloudy , when it snows, "he says.

The sun that reaches us is converted into electrical energy solar panels, which passes through the 'strawberry tree' and enters the phone charger, inspired by the tree as an important ecological and a design of understated elegance, is the trunk of a metal, wooden benches that surround it, cables for different types of portable devices, and a metal roof on which they are placed solar panels. "The basic idea is derived for the tree, and hence its name. The tree uses sunlight to produce oxygen, and our tree used to generate the energy," he said.

The mobile phone was the key, because "everybody has," and only in Serbia, a country of some 7.5 million inhabitants, there are 10 million .

Consumption are small, but if you add the energy of moving 5,000 million, estimated in the world, is no longer enough, he says.

The Tree of strawberries' reaches a 80% energy efficiency , and ordinary chargers only 20%.

It also has an educational aspect because it brings users to the concept of sustainable energy and social one, because all three in the country have been installed in streets or places frequented its banks and people meet, chat and exchange views while waiting that the batteries charge.

In Serbia, the charger has been installed also in the northern city of Novi Sad, and Obrenovac, 35 kilometers east of Belgrade where the largest thermal power station in the Balkans.

"By 2012, we intend to export shippers , install at least one, modestly, for starters, out of our country, and we hope to become a reality, "said Milisavljevic.

The team of eight students of electrical, mechanical, architectural and colleagues say they want to make the world a better place by contributing what you can and ask everyone to give a small contribution because it "may come up with something great." "What matters is that people understand, because you think you alone can not do anything and therefore does not have enough motivation," he explains.
