Peculiarities of the National GPS-navigation. Moscow

Positioning systems and terrain orientation based on GPS (Global Positioning System) are becoming more affordable and widespread. Scheme of their work is simple: GPS navigation devices receive signals from special satellites, process them and, based on these data, can calculate the current location, speed, its direction. In mid-March had the idea to supply the tourist group, is preparing to make a sports trip in the Polar Urals, several sets of GPS-equipment for testing of the equipment in the Far North. PDAs were kindly provided by MakTsentr, and GPS-receivers by CB-Grad.

Preparation of equipment and software

As a result of the development project was agreed that the keyboard device is unlikely to be used effectively in the field, so we were prepared two sets of GPS-based devices running Palm OS and Windows CE.

Palm OS

Apparatus

In preparation for the campaign had to choose between two options with one common shortcoming manifested itself in different ways. The first GPS-kit consisted of a Palm IIIxe and GPS Rand McNally. In this case, Palm is powered by batteries, and GPS-receiver for some reason the battery, which can not be recharged in the tundra. The second set consisted of a Palm Vx and GPS Rand McNally. Here the situation is quite the opposite - PDA powered by a rechargeable battery, and GPS-receiver battery life. This option seemed more successful, because the battery life battery models Palm, as experience shows, quite long. If the battery charge is not enough, then there are compact devices for battery recharging Palm, for example, batteries Krone. Statistics as a resource storage of GPS-receivers has not been practically none at all, so a variant with Palm III has been dropped.

Considered another solution for Palm OS - a bunch Visor + HandyGPS by Nexian a connector Springboard. At first glance, this option seemed to be most successful. Both devices are powered by batteries, a set of fairly lightweight and compact, but ... Unfortunately, HandyGPS does not work with standard protokolomi exchange (NMEA-0182, -0183, etc.) between the GPS-receiver and mapping applications. This device operates within its own protocol, which is only supported special supplement HandyGPS. Thus, the variant with Visor'om dropped.
Peculiarities of the National GPS-navigation. Moscow
Among the virtues of the past "qualifiers" Palm OS GPS-kit, we can note a small weight (about 500, with three sets of batteries), small aggregate size. Disadvantages - no quick way to backup the data obtained on the route, the lack of a backup card and the necessary software, as well as quite a long time-selected for the complex GPS-receiver on the operating mode.

Software

For Palm devices there is only one application that allows you to work with raster (scanned) maps using GPS. The software firm Atlas GPS Pilot. The process of preparing maps is fairly simple.With the help of free utilities any scanned image can be transformed into a database for applications Atlas. You can then enter the area and link the card. Moreover, the binding is carried out by two points, and the card must be soorientirovana north. Procedure is quite responsible, because the quality of binding, as you know, depends on the correctness of the entire future of the complex.
Peculiarities of the National GPS-navigation. Moscow
Peculiarities of the National GPS-navigation. Moscow
Testing of this complex and the software before sending it we have decided to hold district Taganka. For large-scale maps of the distance between the anchor points were only about 80 m, and that was enough for reliable operation GPS. However, in the process of testing revealed a few unpleasant moments. The main difficulty is to find the point at which the GPS-receiver receives signals from satellites steadily and reaches a reasonable level of accuracy of positioning. Atlas means to determine the moment of the GPS-receiver on the operating mode to bind the card fails. We have to use a small, freeware utility NMEA Monitor, which displays all coming from the GPS-receiver data in raw form.
Peculiarities of the National GPS-navigation. Moscow
Peculiarities of the National GPS-navigation. Moscow
The picture shows the beginning of the GPS-receiver. The list shows only two numbers after the equal sign. When their number is four, there is still some tongues, one of which you can see the latitude and longitude values, issued a GPS-receiver. It is necessary to wait until these values ​​are no longer monotonically increasing or decreasing. Once they begin to oscillate around a certain point, we can assume that the GPS-receiver is ready to work. Of course, if the path to the second anchor point GPS-kit does not switch off, then the second time this procedure is not necessary. Another disadvantage is possible to name a few ill-conceived system of working with anchor points, and waypoints. Working with their parameters through an awkward system of windows and menus. For example, the great danger of accidentally deleting a waypoint instead of the entire map. No built-in zoom map: find the right spot on a small PDA screen, especially if the card is great, very difficult. Nevertheless, the Atlas is a definite plus. You can absolutely have no idea of ​​geodesy. Enough to remember some of the action sequences in a program to train in a familiar area, and can safely go into an unfamiliar forest for mushrooms. In addition to display the location on the map Atlas can display speed and direction, altitude, magnetic declination.

So, found in the Internet map of the Polar Urals was safely passed through the converter and placed in the Palm. For the guys had written a quick tutorial on using Atlas'om.

Windows CE

Apparatus

In the case of Windows CE, it was decided not to philosophize sly and use the already quite well-proven combination of Cassiopeia E-125 and GPS-receiver Garmin eTrex. Both devices allow you to replace the power source (batteries in Cassiopeia and AA batteries for eTrex). Cassiopeia has always been famous for its beautiful color screen and its application in GPS-kit involves the use of colored cards. However, the advantages of color maps is particularly evident in the summer in rich vegetation, and water obstacles areas. In winter, so even in the desert tundra of the Polar Urals, it is possible to do a map in black and white.
Peculiarities of the National GPS-navigation. Moscow
Stability and correctness of the eTrex many tested and is beyond doubt. Unlike Palm OS kit, GPS-receiver sets Windows CE can be used independently. The problem of determining the release of the GPS-receiver on the operating mode is solved in hardware. On-screen indicators eTrex is the number of satellites and their level signals. It also shows the current positioning accuracy. Cassiopeia can work with non-volatile memory cards, Compact Flash, so the problem of storing large amounts of cards can be considered solved. Unfortunately, in the case of a hard reset (Hard Reset) with the loss of the contents of memory are unlikely to be able to reset the application, since the built-in tools to work with CF-cards in Cassiopeia is very limited. Large total weight of the package (about a kilogram of batteries, wires and batteries), as well as the need for bulky connection cable, composed of two parts, seemed to arguments against. The second circumstance, however, was then an argument in favor. But more on that below. What is known about the appetites of Cassiopeia in terms of power consumption makes you think about the short period of Windows CE kit even in the presence of two additional battery for Casio. But tests in the Far North have placed everything in its place.

Software

For software to work with raster maps and GPS-Pocket PC hardware shows full solidarity with the Palm. No suggestions. The only existing application - OziExplorer CE. By itself, OziExplorer CE impression of a very high quality product, with a lot of opportunities. In general, the way it is. However, among the many advanced features not, perhaps, the most basic: the possibility of binding maps of the terrain.
Peculiarities of the National GPS-navigation. Moscow
Peculiarities of the National GPS-navigation. Moscow
Scanned map is passed through a special converter, which prepares both herself and scaled up. For the user, this procedure is completely transparent, and when using Ozi transition to a different scale is very fast and convenient. Thus, the card is placed on the CF-card, configure the necessary ways (this should definitely read the documentation, all non-trivial) and ... nothing happens. Ozi offers to open only one. Map-file, not. Ozf2-file, which turned the original map converter. What's the matter? It turns out that OziExporer CE do not know how to attach and adjust the binding maps. Prepare them only in version OziExporer desktop, which costs money. A OziExporer CE only works perfectly with the already-bound cards. Work on the binding map requires some knowledge of geodesy. However, the problem is applied and fully mastered by many.In the networks have found a lot of theoretical and practical material, but the story about this is beyond the scope of the article. Subject of an interesting and worthy of study.
Peculiarities of the National GPS-navigation. Moscow
In the end, the map of the Polar Urals was tied to the available points on it with the values ​​of latitude and longitude. Generally, there are many options for bindings. Most likely was not chosen the most correct of them, in connection we doubted performance Windows CE - a kit.

Paper GPS-Kit

Consisted of a GPS-receiver eTrex and notepad with pen. All indications of waypoints were entered in the notebook as you travel.

Packing

No special carrying cases at our disposal was not. Besides, it was interesting to find out the stability of devices to allow an external physical influences. The only precautions are standard protective film on the screen plus Silkyboard for Palm. All devices were neatly packed into a thin cardboard box, which for greater moisture protection pasted tape.

User

Honestly, was drawn up hastily, as the dates for the preparation of the expedition were pretty tough. Whether this statement in more detail may subsequently have been able to avoid several mistakes.
Peculiarities of the National GPS-navigation. Moscow

Conclusions (preparation):

Palm OS set seemed more suited to the tasks of GPS-navigation users with good skills to guide the application (that is just for tourists, sportsmen). Binding capability maps directly on the ground to avoid the study of the theory of making topographic maps. However, we must know exactly where you are at anchor, and also have some experience in dealing with both Palm, and GPS-enabled. Using a trained and properly attached maps for Pocket PC is very easy and intuitive. User Windows CE does not need to have extensive experience in guiding, but the procedure is binding maps on a desktop computer requires theoretical knowledge, as well as some experience on the use of OziExplorer. Windows CE-package is heavier and cumbersome. Thus, GPS-sets collected and prepared for two-week trip. Train Moscow-Labytnangy "kills four members of the campaign with riot gear in backpacks.

The new budget handheld Sony PEG-SL10: stylish and affordable

Market introduction of cheap and very cheap computers Palm (or rather - "palmoobraznyh") may be considered not just good, but very good news. Small computer for the small amount of money will lure not only the nuts on a miniature computing users, like me, but people hitherto on the handheld machines do not look. If no awareness of the urgent need for both fashion, not fashion, so the low price - something still incline of the potential buyer to try Palm, in fact. And by "try" to "get hooked" on Pocket PC (health is perfect, mind you, inoffensive, and even in very useful) one step. And I'm living proof that ... The release of the new Pocket PC budget class Sony PEG-SL10 coincided with a significant event for me - except for time-tested (and what is really there, my own stupidity) Casio BE-300, I won a Palm m125. And, I must admit, it causes a storm not put me on the age of delight. Indeed, the machine excellent, extremely functional. Nothing more, but all you need creative person to work (and for fun too) is present. This fact is of little significance from a private life, I mention only to inform - to compare different model palmoobraznyh "I'm now much easier. Practice is practice - against the backdrop of daily hours of testing m125 (I hope he survives this abuse), theoretical arguments about the unknown models become necessary share specifics. It is hard to describe new machines, not knowing clearly what they have on the screen, right? According to the old "chaynikovskoy" habit will start with what pleases the eye - from the exterior of SL10.

Exterior

Externally, the new Sony PEG-SL10 - it is a miracle. And not "feathered" as many Chinese clones, of which we see only in the foreign press releases (I do not know whether this is good or so-so), and a miracle in the literal sense. Grace on the verge of perfection. Beauty that flatters tired boring technocratic style of soul.
The new budget handheld Sony PEG-SL10: stylish and affordable
Those who saw in his hands, or personally owned one of Sony's series of T, are aware that these machines are not only amazingly comfortable, but very beautiful. As thin as foil-chocolate bar, aluminum body, tiny buttons, a deep black (monochrome or color - no difference) Such a computer screen ... pleased to pick up. This prestigious thing. Other "palmovladeltsy" (and those who understand) obzaviduyutsya into the board. Even my Palm m125, to the exterior of which I am still not used to, but because I think very spectacular, "face" is clearly a rustic. Next to my Sony m125 looks like a rustic shepherd near the Princess ... The design resembles the design of computers SL10 T series, but not copy it. True, the body is noticeably thicker - for use as a power source replacement elements AAA rather than a lithium battery (the first computer from Sony, which has no battery), and he himself is not aluminum, and plastics. But the ergonomics have changed for the better. In addition to its navigation wheel on-screen menu (jog dial), the back button (back), located on the left side of the body, except for four call buttons main application, one of the major governing bodies Pocket PC are the scroll button (which is exactly duplicated jog dial 'th). Members typewriters Sony knows how inconvenient thing - these buttons. Tiddly, neuhvatistye (or, more precisely, "nenazhimistye"), although, no doubt, beautiful to an inability to ... But we also do not look at them, pressing need! Here's Sony in their first computers SL series and made the navigation buttons to be normal. Beauty is not affected.

Plastic casing - does not lack, as it may seem in comparison with, say, Sony T425 (excellent monochrome computer). Indirect evidence of this is the story of a laptop Titanium from Apple, located in the merciless daily operation of my friend. Rugged metal housing of this machine is prone to scratches. Product appearance is lost fairly quickly. And it's Titan - one, and a notebook - two. What to say about the painted aluminum, and PDA, a place near where keys and other small things barbed? A good plastic (and PDAs are not made from some kind of nonsense) is durable and, in principle, a more ergonomic than the metal. Although the species is certainly not a representative ... Pick up a typewriter in the cold (near zero cold "thieves" can not tolerate). The plastic will warm the palm, aluminum - cool. However, this is not an argument, of course. I just want to say that plastic - it's a bad thing, especially for such a cheap machine, as the SL10 ... What else - of the features? Slot Memory Stick (other than the Sony impossible) in the upper part of the body. Near - infrared transceiver box and the power button (backlight).
The new budget handheld Sony PEG-SL10: stylish and affordable
"Flaming engine" is the usual 33-MHz processor Dragonball. Memory on board - 8 megabytes. Operating system - Palm OS 4.1. That is all like a normal Palm `s.

Food

Application in the SL10 replacement elements instead of the internal battery has as its cause - the maximum possible reduction in the cost of the computer and its consequences. For a start try to evaluate - do not move it back and whether their computer is on battery, though not too big, money. In everyday practice, when the PDA is used on the way to and from work, built-in battery thing is very convenient and profitable. Battery life for 9-10 (the monochrome models, T Series) or 7-8 hours (colored computers Sony) will suffice for the whole day. Are not going well on the handheld machine prodelyvat serious work? But for "killing" time, or use a small computer as an electronic book (handbook, cribs, handheld game console - whatever) battery charge is enough. Another thing - a long trip or a clear lack of access to the electrical outlet. Here's the situation - you go on holiday abroad. Palm (or Sony) course with itself. And to him - a set of "Travel Kit", consisting of a heap (okay, let a handful) of electrical adapters. There's also another outlet, not our standard. Moreover, in each region - their own. And the computer from this "Travel" ceases to be a pocket, turning into a "suitcase" ... And of plug everything easier. Batteries are sold even in the dense pampas. This is the same seller as well as chewing gum ... So nobody knows what is ultimately better - built-in battery (limiting the life of your computer a couple of years), or removable elements (which can be regarded as the power source of unlimited capacity). Another plus is revealed upon closer study of the target niche, for which the new model. Its the cheapest PDA Sony addresses the youth. And in a nice young age, people generally are not burdened with offices or even desks. Know yourself - a young, green, in the head walking such winds, even jealous ... where to attach the cradle to recharge the battery (while the SL10 and it does not)? But in the pocket "bezofisnogo" owner of the new cars full of every electronic stuff - the same music players that use removable elements of AAA. In a sense, get some kind of universal.Do not have very wise of recharging the empty "cartridge-, right? However, in the two older models of the series - in monochrome and color SJ20 SJ30, which now will soon be submitted after we viewed by the machine - used in lithium batteries. But the price of cars, respectively, above.

Screen

High resolution "palmoobraznyh" computers from Sony has long been talk of the town. " That, they say, how to do handheld computers - to patch on the screen was 320 by 320, but not pathetic 160 to 160 points ... But nevertheless the question arises - but should it really? Use the maximum screen resolution, Sony's latest models (those that support hi-resolution) is usually sporadic. View photos - is yes. Toys? Maybe. Normal working program (reader, pisalki, risovalka, rhymes) - no. When you enable high-resolution, where applicable, the system fonts are thin (even transparent), it is difficult to read. Different file navigator, and the shell can accommodate a much larger number of icons, but what they see on such a small screen? As for viewing photos, then this is an amateur. A scrolling video (without sound!) And does seem to me ... with the current - "Ponte". True, he is not neglected. And I'm worse than others, or what? Whatever it was, but certainly a plus hi-resolution can be considered as additional options that appear in computer owners Sony. You can enjoy high-definition options, but you can not use it. Especially because the cost of machines, according to new models of the series SL, it has no effect. Now about the actual Sony PEG-SL10. With the screen at this girl, alas, not the glory of God. The deep black color - like the T415/425. Image contrast and bright. Illumination level. But drawing the screen very slow. Change the picture is about half a second. For dynamic games (and, note autoscrolling in reader) will not do.
The new budget handheld Sony PEG-SL10: stylish and affordable
What is it - the price of high resolution in the budget PC? Or use is clearly unfinished matrix? Most likely, something, and more. Although the inhibition seen and when you run in the normal resolution 160 by 160 pixels. For some people this lack of a new computer (unlikely or unique, but - what!) Will be decisive. We still display "brake" is not enough - all well-known simplification of the operating system Palm OS. Something's wrong here ...

Some speculate

Figure was, unfortunately, not all. Soothes only that a matter of time. Not today - tomorrow will be a new computer in our stores, then all of understatement clearer themselves. Here, for example, the communication connector. In models of senior-level line - SJ20 and SJ30 - used the system connector HotSync from the series T. Respectively, and all the accessories that were released for the PC series of T, will come to SJ20 and SJ30. And what about the youngest SL10? It is said the first review, integrated port USB. And the cradle in the standard package is not for synchronization use the "string" USB mini-connector.
The new budget handheld Sony PEG-SL10: stylish and affordable
And then there are a number of issues.For example - whether produced any original accessories for the SL10, or the computer will "Kazan orphan? Suit if the computer does not "pocket" and normal extensions with interface USB - Modem reader for memory cards, external disk drives, keyboards? If possible at least theoretically (for instance, Sony itself is not going to write drivers, but we also fully zlatorukih folk art), why charms USB deprived older series models? And why not talk about this innovation? Personally, I would have raised such an enthusiastic high, ran away to all computer-related brethren. The presence of regular USB port on the Pocket PC entry-level price - it's a real revolution. No problems with the periphery, can you imagine? Or in the SL10 uses some kind of originality raspolovinennaya modification of USB. Again - why? Or in the SL10 uses some kind of originality raspolovinennaya modification of USB. Again - why? Either I do not understand everything, or one of two things.

When the wait?

Terms rollout of new computers (and the SL and SJ will come most likely together) still seem to be announced. But in any case it is the beginning of the school year - that is, not later than the beginning of September. New low-end models have forced rivals Sony (the company itself Palm) to drastically reduce prices on their computers. In the near future, perhaps we should expect further progress and to Sony, because the line SL in one way or another will have to compete with more expensive models from the same manufacturer. I think in the older typewriters series will add some to justify two or even three times the difference in the cost of computers. With regard to exports to Russia, then a long wait we do not have to. Sony is too significant player in the PDA market to remain unnoticed by the Russian sellers of computer technology. And her computers too good to lie around in warehouses. True, I would not count on those $ 150, for which Sony PEG-SL10 will be sold in Western markets. We will ask for this machine is more expensive - as always, of dollars to 50.

Peculiarities of the National GPS-navigation. Polar Urals

26.03.01

So our trip begins!
Peculiarities of the National GPS-navigation. Polar Urals
Exit from the car of a train with the romantic name "Moscow Labytnangy" and immediately understand that "here you are not here! Although, like, and the weather is nice, but pulling a breeze blows through. But the cold can not stop our leader - this fighter for the promotion of technical progress in the Far North. He immediately tries to bind the card into the Palm Vx to the coordinates of our real position. Standing in the cold, patiently waiting for the completion of the historic moment. We, too, for the progress! In general, ... Associated all-terrain vehicle, an unknown, but rather "prohodimistoy" design, gives us, as follows, to warm up walking and dovozit almost to the entrance to our valley - a point of departure. Vzmetnuv to the sky clouds of snow treads, he is hiding, but we are going to ski a bit further and get up on the first night.
Peculiarities of the National GPS-navigation. Polar Urals
About -20 and the wind. All are engaged in furnishing life, but our leader is only interested in the process of "binding of the second coordinate" in the Palm Vx, Cassiopeia E125 inspection work and GPS eTrex. It turns out it works! "Unexpected" is called. And even what we see on the paper map, and around, completely coincides with the instrument readings! Fall asleep, it is nice affected power of knowledge.

Conclusions of Day:

GPS for Palm Vx shows that he had found as many as 12 satellites for a long time to move to the small screen some numbers. Waiting for results is delayed, and in fact does not end. So it is not clear - the receiver has identified its location or not. To make sure that the satellite signals received clear and you can work on, you need to go to another application (NMEA Monitor), but it's not very convenient. Another subject - eTrex in conjunction with the Cassiopeia "savvy" is much faster: catch the satellite signals and then displays the accuracy of the coordinates.
Peculiarities of the National GPS-navigation. Polar Urals
True, Cassiopeia E-125 so far focused on the ground worse than us: the difference in determining the point on the map is about 800 meters. While the maximum precision of our measurements - 6m. This is probably due to the fact that the map for Cassiopeia had to cook on a desktop computer. The coordinates of the night:

Playing catch-up, or Casio BE-300 against Palm'a

When we were about a year ago, first learned about the Casio BE-300, followed by computer analysts began to call him not only as "killer." Well, yes - "Killer Palm'a. Wild, wild boar. Bloodthirsty vampire ...
Playing catch-up, or Casio BE-300 against Palm'a
Casio BE-300
And what is he a vampire? In the sense - it is, little darling "Beshka? Look at it closely. It's just a pocket-sized machine. Cute and comfortable. Miracle, not a computer! And to suspect it of predatory intent - a grave sin. She did not kill anyone and does not intend to kill. As they say, Palm'u palmovo and "Behe - behino. Is not it? By the way, nice to talk more substantively. Identify strengths and weaknesses, to compare features of the application. Perhaps these arguments will help someone make a choice in favor of the BE-300 or Palm'a. You can not spend money on, and on both. While I - has spent ... very much wanted to try for yourself. It happens.

Beauty - terrible force

We compare the computers of about the same class. On the one hand Casio BE-300, on the other - Palm m125, and (when it touches of color and power from the internal battery) m130. Still, these cars are close in value and are not too money-user.
Playing catch-up, or Casio BE-300 against Palm'a
Palm m125
Externally, BE-300 looks decent, but intelligently. In her case there is no right of brilliant linings, nickel grids and other tinsel. The buttons are the arc and have an elongated teardrop-shaped. To its credit, Casio should be noted that the buttons well protected overhangs the hull, and press them by accident is almost impossible. At the same time trigger buttons clear, with a tangible tactile feedback. As navigation devices in the BE-300 uses flat mini-joystick - a large diamond-shaped button, which has four degrees of freedom. However, perhaps all eight, but the intermediate positions, I never felt (perhaps feeling the ill). This navigation button is properly performing its functions, but sometimes it still fails. Flipping through a book-reader program, I occasionally inadvertently press a button instead of upwards and upwards and sideways (yeah, that's you and the intermediate position!). And the book machine can be browsed through at the beginning ... We have to come back, find the desired page. Favorites, I do not put ... In short, happens. Plastic, from which the casing is made of BE-300, scratch-resistant and has a matte, textured surface. Smooth only silver inserts on the sides. So keep the machine in the hand easily and comfortably. Even in the heat of the computer does not slip from his hands and did not seem wet. But the silver insert themselves I do not like. And who like painted plastic? Bullshit some, honestly ... But the overall impression does not take away ... Now, take in hand, Palm series mXXX (in our case the m125). In my opinion the body of the inexpensive Palm `a little simple-in registration, but quite ergonomic. Lower body tide, concave button - fingers as expressed in young people, relax. Did not like the button on the computer (and the backlight). Tight, works with a loud click. But sensitive - in defiance of BE-300, in which food, sometimes, on / off is not the first time. But really liked the protective cover that shields the screen and the Palm `. In m125, it rubber, soft, with shaped bulge on the lower side - on-screen aperture, with a Plexiglas window through which you can see current time, not including the Palm - by pressing the scroll up through another cut in the same cover. Protective cover fastened hinges to the body of Palm `Yes. Rim loop drowned under a removable faceplate, so just get rid of the cap difficult. But to lose - too hard. To cover does not interfere with work, it can be pulled back.And poluotkinutom situation it becomes a stand for your computer - just like a desktop folding mirrors. And here at BE-300 cover is worthless. It is made by the same principle as in the old Palm `s third series - as a rigid hinged cover for other paper notebooks. Cover can tilt forward, increasing the size of the computer twice. Ago, it does not stack and stand (or, rather, focus) can not serve ... No, awkward thing. At his typewriter, I took it off right away ...

We return to the Palm `y ... plastic base housing at the proper level, the same textured, rough to the touch surface. But removable lid with a silver (in blue m130) insert - into the black of its parts - the slippery hands and even unpleasant. Soap some (if not - tallow). And this despite the fact that the surface of plastic mat, but not smooth ... However, it is unimportant trifle, you can factor out (again - maybe my hands are incorrect).

Palm m130
By weight of both computers (BE-300 and Palm) are roughly equal - plus or minus a few grams are not considered. A Palm in size considerably smaller. And in his pocket is comfortable to wear all the same Palm. Therefore Palm `a set of five round appearance, and Casio BE-300 - Four, but that's Taken a plus.

Window in the microcosm

Now compare the screens ... a difficult task. Firstly, the cars belong to different platforms, which directly compare very difficult. And, secondly, the Casio BE-300 is one of the best screens among handheld computers in general. (Note that this is not just my opinion and the opinion of many users who have tried different machines). Screen BE-300 is built on the technology of passive matrix color LCD. Nevertheless, it looks no worse aktivnomatrichnyh reflective screens Pocket PC 2002. The reason for this high-quality matrix - once, and small (by the standards of Pocket PC) screen sizes. Resolution remains the same as that of the older models of the family - 240 by 320 pixels.
Playing catch-up, or Casio BE-300 against Palm'a
I had a chance to "play" with the color vyave Sony, the screen resolution is 320 by 320, and, of course, compare it with BE. I gave preference to Casio. Even the pictures on it look better than Sony ... Although one can argue with me (I will not resist). Passive matrix (dual scan - so the on-screen BE-300 is sometimes visible band split screen) is slow down your property when displaying rapidly changing images. And it is retarding. In games it is almost invisible - because of low resolution. And when playing video ... also almost imperceptibly. Anyway, to convert movies to "pocket" format with a resolution of 160 by 160 pixels, I will gladly watched wow boevichok (fights, terrible shooting, but at the end of "our" all win). And what headphones - your ears, glasses - in my eyes and see myself formic movie, though obsmotris! .. By the way - to fit the hour and a half movie on a 64-megabyte flash drive, I divided the film into four parts. Troublesome, irrationally (laptop right there next to it), but in principle it is possible ... Palm `from these refinements are not able to do. That "movie" that can run on the Palm `s, it is not. No sound, the screen slows down. No fun.
Playing catch-up, or Casio BE-300 against Palm'a
Color screen for Palm m130, too, is built on the technology of passive matrix, but looks different than the BE-300. No worse and no better, but it otherwise. Even the pictures on the screen m130 I somehow did not liked. That is, they somehow just not liked as compare video playback on these computers really really stupid ... Three features of the screen Casio BE-300 - a nasty, second and third so-so funny. Unpleasant feature - at a minimum (25%) level of the backlight is noticeable uneven illumination of the matrix. Right edge of the screen becomes yellow, which sometimes prevents view pictures and even read a book ("catches the eye, though burst). But it is necessary to add brightness and this effect disappears. Have to balance between power saving and more comfortable screen reading. So-so feature - when you turn on the BE-300 passive matrix takes time to warm up. Depending on outside temperature (and probably the nature of a particular instance of machines), the matrix is ​​heated from one to three minutes, first giving enough contrast. But then the screen comes into operation and becomes bright and contrasting. An amusing feature - the screen BE-300 is not the center of the front panel, as it seems at first glance. He shifted to the left, which is not so easy to overlook. I saw on the seventh month of ruthless exploitation of the computer ... They say, easy asymmetry person a necessary condition of beauty. Judging by appearances Casio BE-300, then the way it is. Now about the screen Palm `s budget. On the matrix m130, we have already spoken. Only add that, unlike older brothers (sisters?) M130 screen more like a darkened room, and even less fond of sunshine. In general we can say that for the Pocket PC on the street will not do any Palm m130, or Casio BE-300. In bright sunlight the screen can not see anything. In the shadow of something that can be discerned. In the room, but still enough twilight - the image is excellent. A completely different situation with a monochrome screen Palm m125 ... You know, I would not call that a small monochrome screen is m125 (and, generally, all the monochrome Palm `s) perfect. I would not call him even more or less acceptable to display grayscale graphics. But this is the only type of liquid crystal display, capable of running completely in all conditions except extreme cold and extreme heat. It is curious that on a monochrome screen m125 looks good even toys - unless, of course, be included on all cylinders imagination "palmovaldeltsa. And working with the texts are no less comfortable than on computers with color screens ... Here, I confess, I'm exaggerating a bit (once in a hundred, not more). Read with a color screen is much nicer than monochrome. Therefore, filling up on the couch with a book, I take all the same "Behu. But starting in the short-lived (or vice versa - in the long) journey into his pocket put - Palm. Ratings for the quality of the screen. Casio BE-300 - Five-one. Four-plus because of the small size put Palm m130. And three - Palm m125. But a strong triple! Muscular like a wrestler Karelin.

When the machine asks a

If we choose a PDA only on battery life, I would go with a light heart, exclaimed: "Brothers and sisters, do not you take this nonsense BE-300! Obrydaetes a board mykayas with a dead battery it!" But the fact of the matter is that lean battery - perhaps the only drawback Casio BE-300 ... But by no means unique. But the rest can be put up (still get $ 250 a full PC based on Windows CE - it is, I tell you, this good luck). On a weak battery, BE-300 is not just lazy writing. And the output seems to be unavailable - external battery pack from the most Casio's Russia is not driven (because blamed for small capacity and high price), the power supply of replacement elements looks horrible samopalom (this is) ... But then I read - "Leather Cover for the BE-300 with built-in power supply.And somewhere I read - on our site! Mama dear, yes the same is the very unique solution that pulls us, the owners of BE-300 from the pool inescapable sadness! Oh, you're my home MakTsentr! What do you really molodchinka ... Give, give the author's imagination roam! Give to dream about this wondrous gadgets. The fact that the BE-300 is difficult to find suitable to sit, as poured, cover (box, bag and so on), commonly known fact. We have to shift, selecting products companies Hama and her youngest daughter Samsonite (or - Xigma). Companies producing these wonderful handbags, some of which are suitable for Casio BE-300, like the people ... The fact that replacement items are packed in a plastic container and connected to the computer wiring, not the most elegant for the BE-300 solution is also well known. But what really can you do .. Now imagine the cover, which has a pocket for a plane ... rechargeable batteries? Yes, at least for the native from Casio (only 10 dollars - nonsense). And - a connector for the charger ... Okay, let the usual elements of AA, the main thing - this thing will not hang out somewhere near or attached to a typewriter eraser pharmacy. What can I add? Only one - waiting for ... The relatively new m130 problems such as a BE-300, operating on internal battery from 2 to 4 hours, no. In contrast, m130 "live" longer than the older models of Palm computers, since the area of ​​the screen it has a smaller, but the battery is exactly the same. That is, the load on the lithium battery, which mainly falls on the provision of energy the backlight screen, and then to meet the computing needs of the CCP, below. This and ample battery life - 8-10 hours (or longer). After suffering from the immediate discharge the battery BE-300, picking up a Palm m125, I feel, like in a pocket-computer paradise ... and evaluation of food I put these: Palm m130 - Five, Casio BE-300 - a pitiful, shameful troechku ( Yet a few hours of work). How much was food for Palm m125? If you can not put the top six, I give him a million dollars. Or even two.

Rise and shine

On the audio features Casio BE-300 can be said briefly - they're gorgeous. Impression of a little spoiled but no built-in speaker. But, you see, listen to MP3 songs better with good stereotelefonov than tiddly speaker giving sound shrill notes of cockroach ... On the sonic possibilities Palm m125 and m130 can say is even shorter - they are not at all. You can not call the sound of beeping buzzer system (which, incidentally, is in the BE-300)? As the clock all the computers described deserve only three points. Wake up faint sounds alarms BE-300 and the m125 I have get through the times.

Droplets fly in the ointment

Ideal computers did not happen ... But you know that without me. The only question is whether these or other shortcomings capable of spoiling the pleasure of working with a handheld machine. Disadvantages Casio BE-300 are in the nature of unrealized opportunities. It would be desirable, for example, without the hassle to use "Behu" paired with a cell phone. But this is impossible, since BE-300 is no infrared port, and communication cables to the popular phone models have simply not produced. But the BE-300 works seamlessly with memory cards and peripherals in the format of CompactFlash. Recognized even Micridrive! Yes, and devices for the CF slot is produced by the thousand ... Expansion cost Palm `s special raises no objections. Sorry, of course, that the periphery of the format SD cards prohibitively expensive. But other devices - the same covers, keyboards, various kinds of cables and adapters - albeit with a spoon, eat. More or less significant disadvantage Palm `and I would call a weak infrared. Stable communication is possible at a distance of 20 centimeters. But more is just not needed. Important - this same port is ... Summing the final outcome, I dare say - no matter what machine you take, whether it's Casio BE-300, Palm m130 or m125, you are in any case not lose. All of the computers - the masterpieces of engineering, graceful, intelligent digital devices, these assistants at work and home. And the cost - look at the price! By the standards of the portable digital devices 200-250 dollars is really cheap. We only need to understand that none of the handheld computers is not universal.Casio BE-300 - a remarkable "sofa" machine. She can be nice to play, can be more convenient to read a book. Or stick your computer under your pillow - so as not to wake for work. It can take with him to the metro, where for four hours in a row no one travels. But if your path stretches over the clock and it happens more frequently than once a year, it is best to choose a color Palm. He easily make it to the nearest outlet, and will not shut down because of battery depletion in the most interesting place. " Finally, for the inveterate wanderers matchplan the cities and villages and not to shun modern digital technology (such as satellite GPS navigator or stuffed unimaginable service functions of a cell phone), a good choice would be a monochrome Palm m125. He is able to perform the same tasks that computers and color. Without any special frills, but honestly and to the last drop ... alkaline electrolyte. The authors, translation:

Russian James Bond adventure in the Himalayas

Russian James Bond adventure in the Himalayas
As already known, June 1, Valery Babanov returned safely from an unusual journey in the Himalayas, whose goal was to attempt to conquer the peak of Meru Central. This mountain is famous for the fact that many have tried to climb it, but none is so far failed. From our newsletter you know that and this time did not succumb to the mysterious summit onslaught climber. Prevented the deceptive nature. But Valery did not lose hope yet to overcome the peak of Meru in the near future. The intrigue of this ascent was that the applicants for the first climb was three. Our competition Valeria was an eminent American mountaineer Peter Takeda, nicknamed the Big Wall (Great Wall) and his partner Deyv Sheldon. At the time of departure from the Himalayas Valeria Americans still had several days to climb. However, no system of communication they have, so the result of their expedition is still unknown. Travel Valery Babanov interesting by the fact that communication with the outside world during the ascent Valery used PDA Cassiopeia E-115, provided by the Company MakTsentr, in conjunction with a satellite phone system Inmarsat. In the Russian practice of such precedents did not exist. With this communication system, we have received and published the tape with the latest news of the expedition. On his return, Valery has kindly agreed to be interviewed edition of our site. I am pleased to present to you the most interesting moments of conversation. hPCru: Remember the adage: "A friend is known in trouble? Tell us, in your opinion can be called handheld a true friend? Did he tell you?
Russian James Bond adventure in the Himalayas
Valery Babanov: Pocket PC I really liked and wanted to even own such a have. Very handy. When we asked Americans ascent parallel to us, try it, they were very surprised that a Russian general, there are similar things. When they saw it in my hands, and cried only: "James Bond!" Twice they sent to him by letters, they really liked it. But, more importantly, thanks to a PDA and satellite phone we Olga did not feel alienated from the world of civilization. We knew that at any moment be able to send news to home. We often receive letters from our friends. And it is very cheer up and gives strength. Therefore, assistance from him was great. I think I answered your question? .. hPCru: We know that when you left the Tapovana, the Americans continued their ascent. They reached the summit or not? VB: About Americans today not say anything definite. When we left, they were at an altitude of 5,900 m. By the way, this is their sixth attempt to conquer the Meru Central hPCru: By the way, what is the height of the summit? 6500? VB: It is not known. Measure should be considered a mythical mountain, center of the universe, they say that the top of its endless and goes into space. Nobody knows exactly its height can range from 6500 to 8000 m. Although (laughs Valery), about 8000 m of course I'm kidding ... In general, hard to conquer it. Total has already been made unsuccessful attempts to 12-13. hPCru: But you'll still be trying? VB: In late August I'm going back to that peak. The decision I made even before the departure from New Delhi. But this time I already know exactly what it was a mistake. Importantly, it is possible. I was in possession of a month. A month is not enough. To make it enough, you must either be born lucky to get to the good weather, or as all ... I was like everyone else. When we arrived, the weather was good for two weeks. But as soon as I started to climb up, after four good days of sunshine it is completely deteriorated. Then followed eight days of heavy snow, five of which I sat in limbo (literally and figuratively at the same time) in the platform on the mountain.When I went, naturally, I had all the supplies to a minimum. Second time to decide on such a long climb, I could not. The only thing I could have done - it's fast climb in alpine style, the easier but more dangerous because of possible avalanches route. However, the weather and there are not very conducive to me: time to climb the 300-400m, and then decided to go down. I stopped in time. Counting the cost, I realized that they were greatly enhanced if I am late. In particular, the purchase of new tickets would have cost a round sum.

Before the decisive assault

The world-renowned climber Valery Babanov gave an exclusive interview with special correspondent HPCru Andrei Kuznetsov in the Himalayas. As you know, Valerie is now preparing for a decisive assault on an impregnable wall of Meru Central, or as it is often called "shark fins".
Before the decisive assault
Interview, which we received yesterday, was transferred via satellite using a satellite phone Nera Worldphone and Pocket PC Cassiopeia E-125. HPCru: Valery as mood and health before the storm? Valery Babanov: The mood is good, feel even better. True, sorry I did not have time to finish reading a book. HPCru: Is there any sign, which may affect the success of the ascent, and which do you trust? VB: Will none. Importantly - the weather. When I went on a new route to the Grand Zharas, I fell into a crevasse, missed eight (rope). Then the avalanche ... These are the signs were, and climb it came out very classy. HPCru: What do you think should be done before you step up the route, or, as you say, tear: check your rope and insurance, to pray, or something else? VB: Pray it never hurts. Come and check out all too:) HPCru: How far will need to go to the top of the separation point? VB: According to preliminary calculations - about 600-700 meters of ice, and then more work on the ridge. HPCru: Why did you give up your first route, and chose the spring path of the Americans? VB: Yes, this route has been declared in the spring of Takeda and Sheldon, but really they were not on it. First they tried to pass through my spring, but then was taken to traverse the claimed route. Due to bad weather and higher they go, and went down. The maximum point reached by the Americans - 5900-5950 m. It must be said that the mountain has changed dramatically since the spring. The lower part of the old route became very kamneopasnoy. So, in my opinion, today the route of ascent on the right buttress seems more appropriate. HPCru: And can it be like to change something on the spot on the wall, if you fail the weather? VB: The route chosen, and in my opinion, it is very logical. And half of the route I have already passed. True, there might be a correction of ice - everything will depend on the snow cornices on the ridge. HPCru: How long can you stay on the platform under the weather? VB: Even though you like, until you run out of food, gas, and, most importantly, the mood. HPCru: How many days do you plan to spend on the ascent of the route? VB: The lower part of the required 5-day work. The upper part in good weather expected for 3 to 4 days. But it is only on estimates, on the spot to be seen. In general, hard to tell because the top had no one there. HPCru: Will you, being on the wall to be interested in letters from home or simply do not have time? VB: Of course I will! For me very important support from home. Between me and Igor will be a constant radio contact, and every day he would send and retrieve mail. HPCru: How will the descent? VB: Two days. HPCru: What do you feel, hanging over a precipice, while paving the route? VB: This is a complex conglomerate of feelings. This includes everything: the terror and ecstasy of freedom, and the feeling that you're the first ... Well, a lot more then. HPCru: A approaching the top of the sensations change? VB: Yes, of course. Gradually begin to understand that victory is somewhere nearby. It must be very careful at such moments it is hard to turn back - you rveshsya to the top. But the feeling of closeness, of course, gives strength. HPCru: Valery, and you are worried, who took on the trip? VB: There is a little bit. Each route, the more new and complex - a step into the unknown. HPCru: How would you rate your chances of success? VB: I do not want to talk about it. HPCru: Where do you usually draws its strength, if you feel that they are exhausted? How to cheer up a situation of extreme fatigue? VB: From the inside, where else, and from his two decades of experience. In the end, each man has a thirst for life. I was always someone waiting, someone peerezhivaet.It's like Saint-Exupery in the story "Terre des Hommes, about that pilot who crashed a plane high in the Andes. He could have died, but he vsegla remembered that he was waiting at the bottom that he someone roads, and this was its main driving force for which he was still alive. HPCru: Did you have this situation yesterday or today, for example? VB: It was not. Yesterday we were playing whist, and now raised in the high-altitude base camp. And then, of course, and another is not easy, but with risk to life is not related exactly:)) HPCru: How is the ascent of Meru? You can give yourself an assessment? VB: I think it is good. HPCru: How many hours you work on the wall? VB: When I work, I work 10-11 hours. It all depends on the situation. When will be a decisive assault, I can work through all 24 hours. Working day I have irregular :-). HPCru: Valery, you have so many competitors. How do you feel about that? This is your "spur" or annoying? VB: It's not that and not another. They are all very nice people, especially the four Japanese, with whom we live side by side and as good friends. HPCru: You said that you can usually anticipate, guess what will happen in the mountains. Your intuition is now "working"? And what did she tell you? VB: So far nothing has been said. To activate the intuition needed a complicated situation, but we will try to avoid it:) The interview was given on September 13 at 20.50 local time in a tent Valery Babanov and Igor Zdanovich, located in high-altitude base camp.
