How to Create Screensavers And Animated Wallpapers For Mobile Phones

by ,

Cell phones now have been completely revolutionized than those of a decade ago. Smartphones can be compared to a powerful computer always within our reach can do just about anything. It goes without saying that we all love to customize our phone to give it that touch of class according to personal taste. For this reason, in addition to the cover, do not leave out the background and screen saver: a site created especially for this is called Red Dodo and is just for us, allowing us to Create Animated Screensavers. Let’s see what it is and how it works.

Note: supported devices are the brands LG, Motorola, Nokia, Panasonic, Samsung, Sanyo and Sony Ericsson. To date, unfortunately, Apple-branded phones are excluded.

Be sure to have on your hand:

  • PC
  • Internet
  • Red Dodo
  • Compatible mobile phone.

Red Dodo is a service (free) that allows you to create wallpapers and screensavers and animated for your phone. You can then create as many animated wallpapers and download them directly to your phone, or download them to your computer and send them to your phone via bluetooth or other kind of connection, avoiding to buy them out of pay sites.
To use Red Dodo and instantly create your own animated backgrounds we must first reach the Italian version of the site by clicking on this link.

The main page for Red Dodo customizable screensavers and wallpapers and some of the first thing that catches your eye is that the backgrounds are animated, truly original feature. The animations available are divided into two different sections, depending on whether you want to use as search criteria the popularity of the image or the chronological order. When you have made your choice, you will see a series of pages with all backgrounds. To scroll between pages just click on the numbers in the “page” until you find the wallpaper that you want customize: to each background can be of arbitrary text that appears in a particular area of the animation.

To select an animation, simply click on it: you will then be brought to a page where you can enter the text you want to display on the animation and choose the make and model of your mobile phone, in addition to the resolution. You can also delete the animated portion of the image in case you find that consumes too much battery.

At this point there are two ways to save an image: the first is to click the right mouse button on the image and select “save image as” to save the animation on the computer and manually sending on mobile; the second case is to download the image directly to your phone (via WAP internet, so attention to connection costs) by following the instructions on the site.

3D Technology for TVs

by ,

Let’s face it: everybody a little kids – even the most inveterate of us tough and – when the movies 3D surrounds us with its ghostly special effects. So natural that many came the idea that you can have in the comfort of your home something like that, and since the home 3D is a proven reality we see all to figure out what it is.

3D technology for TVs

The unique charm of 3D technology has captivated everyone, but certainly not everyone knows that there are several types to choose from before buying, and that sometimes the differences – that prices – are abysmal: Let’s start with the most common, i.e. those which require the presence of a pair of glasses.

There are two types of 3D technology with glasses: the active and the passive, both with their strengths and their weaknesses. Let’s start with the active: spectacles costing relatively little, are compatible with different brands and types of TV – non-trivial thing – weigh and clutter up shortly and also even after hours of use does not tire the view. The speech is rather different for the active 3D glasses, which have a number of very different characteristics, if not opposed in certain cases.

3D technology for TVs: which one to choose

Active 3D technology has in fact from his less defects like ghosting or cross talking compared to passive, but from a certain point of view the end user “pay the price”. What? First, directly in the store, because you have to pay to buy them a lot more than a couple of passive glasses. Also it is a thicker and much heavier and accessory that goes specifically synchronized with the TV, which also must be compatible.

The faster you pay also with a little eyestrain: better not to go beyond the 4-5 hours of continuous viewing transient penalty but pesky annoyances in the eyes. There’s no way so enjoy the 3D technology without these glasses a little uncomfortable?

In fact, you. Just recently the big companies are starting to get the first few markets TV models with built-in 3D technology and which does not require any type of accessory: How do they work exactly?

Basically don’t need glasses because you directly on your TV there is a kind of film can do da lens through which then our eyes perceive the magic of 3D. The cons of such a wonder?

There are and there are many. The first, is the price: for models currently on the market is called an outflow not less (roughly) to eight thousand euros. The second, is the surrender: we are still far from achieving a 3D even remotely comparable to the effects obtained in movie theaters and the road ahead in this sense will still take some time.

What is the active 3D in TVs

Let’s start by saying that in the present state of things, the vast majority of 3D TVs on the market it should be used in combo (combination) with special glasses: 3D TV without glasses are starting to look at but this is still a rather immature technology and, just between us, expensive.

Therefore when purchasing TV & glasses everyone is facing a classic choice. Making the decision to purchase a pair of glasses with passive 3D staandard-cheap, lightweight, very easy to use – or opt for the more modern and technologically active 3D avanzaro? In many choose the latter, let’s figure out together the pros and cons of this type of innovative accessory.
Active 3D, pros and cons

We can start with tell you that if you choose to bring a 3D active system will have to prepare psychologically to the fact that indeed is a bit more expensive. Good news is that it is compatible with all types of TVS currently on the market: LCD, LED, and also the most modern Plasma.

Active 3D technology provides that the glasses – who need their own separate power supply – are synchronized with the TV so that I can run that game alternating opening and closing image in the two eyes that, at the end, “tricking” your brain creates the 3D effect.

What’s left to say yet about the 3D active? We also observe some disadvantages, in addition to the price: the active 3D makes the pictures a bit darker than they actually are, and this for anyone who uses Plasma – by their nature can play better on black – it could be a problem.

And the hassle? In fact using goggle for several hours continuously active 3D type you encounter some eyestrain, fatigue than with passive glasses in fact does not manifest itself but, let’s be clear: any film lasts well below at 5 hours and beyond which are used to make this type of effects!

Continuing our series, we find also another small flaws of active 3D glasses: the footprint. In fact since their autonomy and their glasses with a chip inside inevitably don’t weigh very little.

Returning to the benefits of this technology, we can not forget the most hated ghosting and crosstalk: respectively the display of faded images and interference between the image intended for one eye and another image destined to the contralateral side. We are happy to tell you that these are two scourges that afflict more than anything else the users of passive 3D and it is very rare that these phenomena occur with those who use the other type of glasses.

How to Use The Launchpad

by ,

The Launchpad is a very useful tool to DJ and those involved in electronic music, even at an amateur level and allows you to play a song or musical sequences. It consists of 64 keys and each of the buttons correspond to a preset sound via computer. So what of it and how to best use the Launchpad, even if you are novice to the world of electronic music DIY.

Launchpad, as its name suggests, means “launch pad” and this tool is a very useful accessory to those involved in electronic music at the professional level and also for those novice, wants to start taking the first steps in this context as a hobby.

The launchpad is a medium sized accessory that is shaped like a tablet, comes with 64 keys, each of which corresponds to a sound, your computer sets via your computer thanks to special software, and allows you to play your favorite songs, or inventing new through the composition.

To use the Launchpad you need to be very handy with his hands and fingers especially, because to play a song you have to master all 64 keys that make up the keyboard of the Launchpad. Each key corresponds to a preset sound to the computer and to create the correct musical sequence is essential therefore know to perfection each of these.

To use the Launchpad in the right way, the first thing to do is plug it into your computer via USB cable, which is typically provided along with the Launchpad. If not, you can use any other compatible USB cable.

Along with the Launchpad, at the time of purchase, also comes the software needed for operation of the instrument; the software recognizes the launchpad automatically, although, in some cases, you may need to enable the hardware according to the directions to download it directly from the menu.

When the Launchpad will be connected to your computer properly, you can begin using it; each button can be customized at will, even according to your own way of moving your hands or fingers, even if you are left-handed.

Each key is also a color; yellow for the clip, playback phases green and red for the registration phase. The colors, of course, are only indicative and may change according to the models: what matters is learning right now to familiarize yourself with the settings and options.

At the beginning may seem difficult and complicated operation of Launchpad, but it is just to do a little bit of practice, and compose the songs you desire will become simple and intuitive. With the Launchpad you can compose the songs you want, then replaying them or create original tracks. Who is able to play one or more musical instruments, especially if a keyboard, will obviously be more benefited, as he will be a little less those starting from scratch, although everything is solvable with just a little practice.

Typically, the first horizontal row of keys contains the procedures to set up the clips, while the central area is used to control change and numerical variation according to the settings you created. Each clip corresponds to a track and you can scroll the workspace moving with the four arrows in the left side of the controller. The central area is divided into two operational areas; the first four rows of the top Act on the clip, while those of the bottom serve to activate the audio channel, stop and mute.

Washing Machine with Dryer

by ,

To wash clothes and linen in the house, the washing machine is an appliance. To find out which washing machine is better off buying for your home, in this article you will find everything you need to know: what types of washing machines exist, how they work and what are the stages of the wash cycle, what is the spin cycle, such as what accessories and safety devices shall, where installation at home.

What is the washing machine

The washing machine is one of the appliances that has most changed home life. Born to save time to housewives and today also to single men, the washing machine makes life a lot easier and faster for those who want to take care of their clothes.

In no time, the washing machine is able to remove stains, rinse and wring the clothes, in various materials and colors, with specific programs for everyone. With the economic programs that do not last long and that imitate washing by hand and with the help of some products and detergents that do not disperse the colors on the clothes, wash clothes and linens always becomes easier and faster.

In some cases, the clothes are also dried, so in addition to avoid washing by hand, you can also avoid spread. The latest models of washing machines are moving towards an increasingly reduced energy consumption, increasing performance, even in a small space, more and more functionality combined with striking design.

All this breadth of choice makes it quite complicated to choose the washing machine. That’s why we have designed for you a specific guide that helps at time of purchase.

How does the washing machine

The washing machine uses water in most cases combined with detergents, softeners and spotting. The cleaning systems used by this appliance is to soak the garments are immersed in water mixed with detergent and heated by an internal resistance, until the set temperature relating to the program and regulated by a thermostat.

The rotary movement of the basket in which are placed the clothes, will remove dirt from them.

In addition to the technique of soaking, there exists another quite effective on stains, rain, or recirculating RWS cleaning, which consists in a shower of water and detergent from above with some force.

Phases of the wash

With these principles, the phases of operation, which may vary depending on the model and set programs, are basically:

  • pre-wash
    with a detergent placed in a compartment before switching on
  • Heating
    through water resistance
  • Washing
    with temperature and duration determined by program
  • Rinse
  • Centrifuge
    with fixed rate or set manually or by program
  • Drying
    in the case of a washer dryer


The centrifuge is that function which automatically enabled by the various programs or set manually, said in layman’s turns very quickly the basket containing the laundry immediately after washing (the juicer for some items is not expected, as for wool for example, since the latter would felting).

In this way it is as if the linen to be squeezed and then deprived of most of the water that has soaked during washing.

In practice, the more the centrifuge is strong and more the laundry will dry quickly.

Each model of washing machine has its spin cycle, which can be more or less powerful: from a minimum of 800 RPM 800 rpm, i.e., up to over 1500 rpm.

A juicer from 800 rpm maximum might be fine in the case that you have a dryer or have the possibility to let drying clothes in no time, while if your situation is not the one just described, you need a centrifuge of at least 1000 if not 1500 rpm.

Also the spin cycle in a washing machine can be of two types:

  • Fixed
    located in models in which the speed cannot be set: speed is then precisely fixed, does not change whatever the program set.
  • Variable
    is the one whose speed varies depending on the program or that can be set manually by the consumer.

Of course the variable spin is the best, also because the most delicate garments need a centrifuge not too powerful as they may be damaged.

Security systems

The washing machine is usually also fitted with some safety devices, which make its operation more efficient and reliable and prevent water leaking from the appliance, to avoid flooding the floors, or worse, come into contact with the wires of the electric current of the washing machine itself. Some safety devices of a washing machine are:

  • Overflow
    why a sensor monitors the maximum water in the basket, blocking the provision if that level is exceeded, thus avoiding the risk of flooding in the house.
  • Flooding protection
    that has the same goal of the previous system and that system starts if the overflow for some reason has not worked properly: the anti-flooding system blocks your washer if there is leakage of water from the device.
  • Water stop
    that stops the machine in case of failure to the pipes for loading and unloading.

Install the washer and attacks

The areas adapted for installing the washing machine in a House, are basically three:

  • kitchen
  • bathroom
  • laundry room or hallway used.

In the first two cases you exploit the attacks of water and electricity already present in two rooms of the House. In the third case, the washer is inserted in its natural habitat, a specially designed only for care. First of all the place where to install the washing machine is to be chosen according to different variables:

  • space, and then the size of the washing machine itself.
  • load you need to wash all linens of a house.
  • loading and unloading position of water and electrical outlets.
  • convenient location and easy to reach.
  • the distance from electrical appliances such as a dishwasher or refrigerator.
  • silence or noise of the washing machine itself.

Once you choose the location that best suits your needs according to the variables mentioned above, pay a lot of attention to attacks already mentioned, that must be:

  • water attack.
  • drain fitting into the sewers, through which the washer discharges the water used and dirty; It is important that the exhaust pipe is very durable, because you should not break if subjected to pressures higher than the norm; usually the limit is set at 60 bar pressure resistance.
  • the mains in the immediate vicinity of the washing machine. The wiring in the House should be under and earthed and must endure at least 3 kw of power.

Washer dryer

You mean by washer-dryers, a household appliance that incorporates both a washer and a dryer. In this case, after the centrifuge that can also have a capacity of only 800 rpm, you enable the drying phase. In this way, you will have washed garments and also dry.

Also, in the data sheet of your appliance, you will find not only data, but also, of course, washing drying.

The washer-dryer is the space-saving alternative to the installation of a front loading washing machine in column with a dryer or a washing machine and a dryer placed one next to the other.

For those with limited space and has no way nor time to dry clothes naturally, the washer-dryer is the best solution, although prices naturally rise compared to a normal washing machine.

The Electron Microscope Can Magnify An Object

by ,

An electron microscope is a device for watching with a very high resolving power, which allows you to take a close look at samples of sizes extraordinarily small, almost infinitesimal, thanks to the wave properties of one or more electron beams.

The main features of an electron microscope

In parallel with the geometrical optics we have seen the development of a new branch of optics that p was called optical electronics and taking Foundation by the thought of physical scientist called De Broglie. It was 1024 when the scholar was based on the concept of photon, which assigned in light of material properties, to formulate the hypothesis that the material particles could behave like light beams, and can then be equipped with wavelike properties.

Based on this thinking it was possible to create an electron microscope that works by sending the sample to be analyzed an electron beam and analyzing the figures of diffraction which arose. The main advantage of this type of instrument obviously lies in a very high resolving power, which becomes as big as big is the wavelength de beam of light used. Visible light has a wavelength whose value is around an average of around 5000 in, while an electron beam accelerated to about 100 kV has a wavelength of approximately 0.05 to: This means a greater resolving power of about 100,000 times!

This powerful tool allows us, therefore, to observe the minimum facilities and the smallest details that it would be impossible to capture using a normal light microscope, however powerful it may be. The amazing results of an electron microscope are amazing especially as regards studies in biology, metallurgy and medicine.

As regards the technical characteristics, this instrument consists of an electron source, a lens that acts as a magnetic capacitor and that serves to focus the electron beam on the sample you want to observe, from a magnetic lens that acts as a lens, from another magnetic lens always acting as projector and blocking electrons in optical system field , and finally from an item you need to collect the images returned from the microscope, which can then be a photographic plate, a film or a fluorescent screen. The entire system is maintained under vacuum to prevent unwanted electron beam disturbances may occur.

How does the electric microscope

The source of electrons in an electron microscope is represented by a very thin tungsten filament V-shaped, whose negative potential difference is maintained between 30 and 100 kV. The electrons then pass into magnetic capacitor through a hole that is in the anode; the capacitor is intended to adjust the intensity of the electron beam convergence.

The electron beam must be hitting the sample to be observed, which then undergoes the diffraction. Sample parts that cause greater deviation of radiation are thicker and denser ones, which are then darker in the resulting image. To adjust the sharpness of the image you make a current regulation, more precisely in the winding magnetic lens. By replicating this action on the projector you can adjust the magnification of the image.

Scanning electron microscope (SEM)

In this variation of electron microscope, electron beam strikes the sample causes the emission from the same sample of many particles, among which there are also secondary electrons. They are to be identified by a special detector, before being converted into electrical impulses. In this tool the electron beam is not fixed but scanned: ç passes, that is, the sample line by line, into a sequence of rectangular areas.

The transmission electron microscope (TEM)

In this type of electron microscope on the electron beam, before hitting the sample, pass in an area where it has been artificially created a vacuum, and only after passing through the test material.

The ion microscope

The ion microscope is a variation of the electron microscope, built in 1936 by a scholar named Muller. The microscope is the most powerful of all ion microscopes and provides resolutions of the atomic level, with a magnification of about 1.000.000 of diameters.

The ion microscope consists of a cathode with a needle-like tip, on which is sited the specimen to be observed, contained in a small spiral. Then there is a heating which allows a vacuum evaporation; This process creates a very strong electric field between the cathode and the anode, which is intended to accelerate positive ions that originate from the sample to be examined. These ions then strike a fluorescent screen that allows you to view an enlarged image of the area being examined.

This complex instrument is used primarily to examine the surfaces of compound patterns conductors, metals and alloys, as well as for examining phenomena such as catalysis.
