It is the GPS responsible for his acts?

The systems of aid to the conduction based on location by GPS are extending at a high speed. Now that is installed in an appreciable percentage of the automobile park, they begin to arise interrogative: if our navigator GPS provides incorrect information to us and we finished lost or having an accident to follow it, the fault is ours or of the manufacturer?

In Diariomotor.com the case of the conductor of a Mercedes SLR 500, that ended in the middle of a desert and a punctured wheel, of following the instructionses that his navigator GPS gave to him. The answer that received from Mercedes was the following one:

We have to remember him to you (and its client) who system GPS does not replace to the normal maps, or in the opinion of the conductor, but is simply an improvement of trip at the disposal of the conductors, who can choose to use it or no. a conductor uses a positioning system by its account.

The two questions that become in Diariomotor seem to me very interesting:

Why some companies try to make us think that we cannot demand to the new technologies the same reliability that its classic equivalents?
Somebody that puts its SLR 500 by? desert? it is in his healthy judgment, or encouraged by a GPS or their own mother?

I fodder that all aid to the conduction is that, a aid. Him something cannot be imputed that in last instance, is decided by the conductor. But, on the other hand, if we are not going to trust the indications of navigator GPS, then not we bought why it. In the routes that or we know, it will not be to us of any aid, and in that they are new, we will have to deliver the attack to verify if the route is correct or it is taking on the other incorrect direction to us, and so we did not save anything. What opinais?

The Palm like electronic book reader

What is exactly an electronic book (or ebook)? Using the always useful Wikipedia:

Free or ebook is an electronic or digital version of a book. The term is ambiguous, since so much to an individual work in digital format talks about, like a a used device to read books in digital format. Some users do not use it in the felt second and use, however, most precise of “device of free”.
The book-and devices, can as much be a PDA, as a portable LCD with memory.

The advantages of the book in electronic format are numerous. In order to begin, the space: The Quijote hardly occupies 800 Kb, reason why in a memory card thousands of titles can be stored. But, in addition, the digitized book extends the reading possibilities: phrases can be realised searches within the text, be stood out, to make annotations, etc. Not only to novels and books can be taken that we want to read in the free short whiles. There are many professions in which he very comes or to have documents always by hand, catalogues, tables, instructions, etc. Many engineers, lawyers or doctors take always their Palm raises in the work like one more a tool.

The program that I recommend to read our electronic books in the PDA is Plucker. The operation of this program was already seen with more detail, when we tried how to read the news in the Palm. The free, gratuitous fact of being, allowing to choose with enough possibilities the size of the letter, and to eliminate the interface completely, to read to complete screen, makes a perfect application for this task.


Plucker allows to take advantage of the screen to the maximum

It is only necessary to consider a detail: Plucker only knows to turn documents HTML. And the electronic books can be in many other formats: PDF, DOC, RTF… So we will have to turn them to HTML first, if we want to use Plucker or Sunrise. But a specific program called PDAConverter exists that will make all the process by us. He is very simple to handle. We indicate the file origin, we chose the format to which we want to turn it, and already is. If we chose to plucker like exit format, a file will be genrará that directly we will be able to synchronize to our PDA, and to read it with Plucker Viewer (or Vademecum, if it is a PocketPC). PDAConverter also allows us to publish intermediate file HTML, to eliminate parts that we do not want to include in the final version, to modify others, etc.


PDAConverter automates the conversion to plucker from different formats

Gratuitous, ready electronic book sources exist in the network numerous to be leidos in our PDA. It is possible to emphasize the Gutemberg Project, dedicated to compile texts that can be distributed freely. This project began nothing than in 1971 less! Podeis to know more on its purpose, how it was created, how to collaborate, etc, in this section of its page. They exist a great number of books in Spanish. Also title and author can be looked for by. Besides ebooks gratuitous, by all means very good pages exist where we can buy them. Not to be inferior against others, I propose to which already know some, that leaves in the commentaries information exceeds she. Happy reading.

Expansion board SD of 2Gb of Palm

I read in Zonapda.net that Palm has sent a card SD of 2Gb. What you have guaranteed when buying it directly the people of Palm, is that will be totally compatible with your device. And that is what I consider important. The compatible equipment with this card is:

Palm® TX/Zire 72/Tungsten T5/LifeDrive/Treo 600, 650

whereas if we watched the compatibility with the model of 1Gb we see that the supported ones are:

Palm® TX/Zire 31, 71, 72/Tungsten C, and, E2, T, T2, T3, T5, W/LifeDrive/Treo 600, 650

Taken care of with cards SD of 2Gb or more, to all the they do not support them equipment
Taken care of with cards SD of 2Gb or more, to all the they do not support them equipment

So much eye at the time of buying a card of more of 1Gb for your Palm, because if it is not in the list of compatible devices, by something will be.

Published: finally we have empirical tests of what equipment supports cards of 2Gb and as no.

The screen of your Palm makes a noise like a humming?

For a pair years, by changes in the design, the case that occurs some units of Palm can begin to emit a small noise of past high frequency the time. Following the user and of the unit in particular, this one will notice or no. In some cases it can get to be annoying.

The cause seems to be the plastic layer that it covers the screen of the PDA. When it is ignited, this cover vibrates a few micrometers, which produces a noise around 16Khz, audible for the human ear. That exlica why, if we supported stylus in her, the noise seems to disappear. Some users have sent a letter to Palm having asked an explanation, but this noise is considered and not defect of manufacture a normal:

The high pitched sound you eat from electronics inside the palm. It's like to computer, they plows to never totally quiet. These new models have to bigger CPU and dwells advanced technique. With this you eat to backside, that is the fact that the palm is not to longer totally quiet ace to older V models were. For The reason we ask to hard reset is because the less applications you have installed the less noise the palm will make. The dwells applications there plows
installed the dwells the processor needs to work and thus to higher the sound. This is not considered to manufacturing defect and the unit will therefore not sees repaired or swapped since all newer models have this noise.

[…]

For Thank you contacting palmOne.
Kind regards,
Patrik
PalmOne Technical Support

But this problem has solution. Shortage is had that varying the speed of the bus of data of our Palm, stops emitting east noise. Therefore, which we needed is a program that allows us to vary this speed of the components of the PDA.

Before following I want to make clear that to make work our PDA at a speed for which it was not designed he is not something that is due to do if we do not know minimumly what we are engaged in hand. In case of forcing it excessively, we will be able to end posapapeles very expensive.

The program to use will depend on the processor that has our Palm. In my case (Tungsten E2), one is an Intel Xcale working to 200 MHz. This you will be able to find it information in the documentation of your PDA, the page of the manufacturer, or using a tool of diagnosis like SysInfo.


Sysinfo provides detailed information to us on our PDA

For Intel Xcale I have found two programs that have served to me to eliminate the aforesaid humming of the screen:

  • WarpSpeed in the last version, already brings directly an option to eliminate the noise del that we spoke, without at least having to play with the speed of the bus. In addition, it works with other processors, not only with the Xcale, reason why she will be to him of utility to much more people.
  • PXA Clocker also has been worth to me to resolve the problem. There is no specific option, but playing with the values the same result is obtained. Originally it was formed with the values:

    Mem: 100MHz, Bus: 100MHz, Sys: Mem*2 (100×2=200MHz), I disturb: disabled

    but changing a pair of parameters, I have obtained that the processor continues working 200MHz, but with a bus of 66MHz, consequently when applying the changes, very instantaneously the small humming disappeared:

    Mem: 133MHz, Bus: 66MHz, Sys: Mem (133×1=133MHz), I disturb: Sysx1.5

    It does not pass anything either if we chose other options that give like result for example a CPU 233MHz. The battery will last a little less, but in return the recent games will work better. That already enters within overclocking and is personal of each.


The configuration of PXA Clocker that solved the problem

So since we have seen, the humming of the screen is not something against which we did not prune to fight. I believe that this advice will serve enough as aid to people, look for who it enough by Internet for time, since I have been able to verify. For any suggestion or correction, as always, you have available the commentaries.

Presentations with projector from the PDA

Reading like every day the news from my Palm, I have found a commentary in Clié Ux50 on Presenter To Go Digital Secure. This solution, of the Margi company, will allow us to directly connect the PDA to the projector with which normally we realised the presentations.


The assembly is very simple

The attention has called me because the first time that I saw a PDA was the year last in a class in the university and, to show the multiple applications to us of these apparatuses, the professor brought the transparencies of PowerPoint in his PocketPC, and with a software similar to this (he even can that this same one he connected) it to the projector to give the class, avoiding to have to load with a voluminous laptop for something so simple.

As they count well in PDAExpertos.com, one is made up, on the one hand, of necessary hardware: a cable to connect to the tube (projector), a remote control, the cable of current (AC to adapter) and connector SD. The remote control allows to advance or to back down the presentation, apart from which the device adapter contains an infrared receiver by two of its sides, to allow one better communication (in previous models, the infrared port of the own PDA was used).


It includes all the necessary ones to connect the Palm to the projector

And as far as software, it consists of three parts:

  • Presenter to Go Desktop is an application for PC that will be in charge to turn documents of Word, Excel, Powerpoint and Acrobat (PDF), to a visualizable own format in the PDA.
  • Mirror, on the other hand, settles in the PDA, and it allows us to previsualize the created archives.
  • Finally, Presenter to Go is the program that is in charge to project our archives from the PDA. One of the things that have surprised to me more, is that annotations with stylus can be done during the presentation, that soon erase. Ideal to indicate or to observe things during the explanation.


Drawings in the presentation can be done while it is projected

To all this it is necessary to add that S.A. to use the Presenter To we do it to Go with a Palm with sound, is possible to connect to the tube or projector to him an adapter for audio, which would give more impact upon presentment him. In addition, although the Presenter To analyzed Go is exclusively for devices that take expansion slot SD (Secure Digital), exists the version for Compact Flash (for Pocket PC), Springboard (for Handspring) and Memory Stick (for Sony Clié).

Really, a solution very to consider if habitually we must project transparencies duante our work, and want to lighten our suitcase.
