Shocked Problema expandiendo la imagen
Posted by: gilinas - 06-11-2018, 07:07 AM - Forum: Español - Replies (7)

Hola.

He instalado la imagen (NO NOOBS) de la versión 1 (de unas 8GB) en una SD de 32GB.

Cuando intento expandir el sistema de ficheros usando el "old raspi-config" me da el siguiente error:

Your partition layout is not currently supported by this
tool. You are probably using NOOBS, in which case your
root filesystem is already expanded anyway.

¿A alguien le pasa algo similar?

Saludos.

Bienvenidos y bienvenidas si las hubiera.

Que este post sirva para organizar la migración de usuarios de Mordor a este espacio libre.

Atención, aquí se habla de todo y no se expulsa a nadie, a los trolls se les mata de hambre o de aburrimiento. La única limitación es la del sentido común. Hasta ahora no ha hecho falta tomar ninguna medida represiva y la vais a tener que liar muy gorda para que esto pase asi que cada uno se auto-gestione como mejor sepa Smile

Me he tomado la libertad de crear un subforo en español porque me ha parecido que esa era la opción mayoritaria pero discutid aquí como quereis que este idioma se integre en este foro. La única premisa es que el inglés es el idioma vehicular, oficial, común o como queráis llamarlo dado el carácter internacional del proyecto.

Decidid tambien si quereis mas subforos, administradores propios o lo que se os ocurra. Y sobre todo no caigáis en provocaciones que en los próximos días seguro que caerán.

suerte, seguimos...


  Sailing with mobile devices... issues to consider
Posted by: pinguino - 06-11-2018, 02:27 AM - Forum: How I did it - Replies (4)

Until relatively recently there was not much to choose from on the question of how the electronics would be installed on our boat. Depending of how big is our boat, our pocket or both at the same time the usual thing was to end up acquiring devices dedicated to navigation such as GPS receivers, plotters, depth sounders and other extras at prices ranging from a few hundred €uro$ to several thousand... even tens of thousands in particular cases.

This is changing today.

More and more of us seafarers are cruise ships that we decided to manage on our own, as will be the engineering of the electronic installation of our ships. The new high-powered, low-cost, energy-efficient computing devices have opened up some very interesting doors for those who want to experiment with this issue. The current mobile devices that can be found at prices of all kinds (phones and tablets) and open a new door to simple applications to install and operate (opencpn, Navionics and others) with updated quality mapping and enough features to ensure some navigation security. In fact, they are beginning to become a kind of "standard" alternative to the classic of traditional plotters.

Myself, interested in these byte and electron issues, has decided for several years now to ignore the offers of "traditional" brands of marine electronics for three reasons:

1 -Price
2 -Abandonment by the user of the "old style" brands due to Scheduled Obsolescence
3 -Mandatory use of proprietary protocols by brands to the detriment of the general compatibility of the devices

The objectives that a server set itself in principle were:

1 Price
2 Ease of adaptation to the circumstances of each navigation
3 Ease of replacement or repair of parts
4 Redundancy for safety
5 Strength and reliability
6 Simplicity
7 Positioning, plotting on chart, AIS, RADAR integration and any other type of electronics must be obtained at the user's discretion. Manage this data, send it wirelessly to several screens to be able to manage it from any of them.

Finally, using a Raspberry pi3 mini computer running OPlotter I was able to achieve this set of goals.

[Image: IMG_20180522_104149.jpg]

BUT:

....there are several things I would like to tell you about the inconveniences....that I have also found.

I own an Rpi3 along with an AIS receiver and an accelerometer and magnetometer sensor as the navigation center.

[Image: IMG_20180522_104358.jpg]

I have several systems available for displaying the information. 

First of all a 12 Volt Nevir TV that acts as the main monitor. This is used in anchorage and/or port to plan future navigation, study routes, marks and routes as well as to navigate the Internet and play multimedia content Etc. 


[Image: IMG_20180522_105022.jpg]

when sailing -for energy saving- this screen is turned off but my mobile phone is located on the chart table as a screen repeater. In case of complicated navigation or if an AIS alarm is activated, take the phone to the outside and check the data as I navigate for the safest route possible.





[Image: IMG_20180522_104201.jpg]

But when I try to use my mobile phone as an external plotter, I have encountered certain problems.


The first of the drawbacks I've encountered is:

1-Insufficient battery life. As the screen is always on at full brightness, combined with the GPS receiver, WiFi, and power requirements to run the navigation software, I can get about 4 hours maximum, which is not enough for a day's sailing. I can extend this a bit by turning off the display, or turning off the phone completely, during noncritical moments, but this is a nuisance due to the difficulty of manipulating the phone while it is in motion. The only sure way to avoid this is to have a reliable power supply, either a power supply or a 12v to USB adapter.

2-Overheating problems. On a hot day, while charging the battery and running the navigation software, the phone overheats. Fortunately my Moto G3 is waterproof by itself, but if we needed to resort to the use of a sturdy case it would make the situation worse: the phone cools down mainly through the airflow that passes through its back. It'll probably stop charging when it's hot. In full sun, it will not cool down enough, and will turn off the navigation application to reduce the energy used and therefore the heat generated internally.

3-Other things on the phone may have priority, such as phone calls or instant messaging, causing partial or total loss of display of the moving map.

4- If you are using the OPlotter ap as alone wifi server you cannot use phone functions that require Internet, such as weather forecasting, while connected to the Rpi, because the phone tries to send data over the WiFi connection even if you do not have Internet access.

5-If some water leaks on the micro-USB port, the phone will detect it and refuse to charge until the port is completely dry. This is difficult to achieve quickly without compressed air or isopropyl alcohol.

6- Difficulty to manipulate the buttons and the touch screen in a navigation environment. It is not easy to operate with one hand only, or with wet fingers, cannot access the side buttons while in universal mounting, etc.

Fortunately, this past week I have tried something that partly solves some of these problems.

I was reviewing the general state of the electronics and its connections when I noticed that my old -1999- Garmin 12XL that was always on the  nav station due to redundancy and that I had in case of occasional electronics failure, was starting to cause problems. The pushbutton panel was not responding, the rubber coating was coming apart. I thought I would have to replace it and think about it and after several hours of surfing the Internet the conclusion was that I would replace it with a "rugged" phone. There are many models of all kinds of power and price on the net, but one was chosen whose cost was not higher than the GPS it was intended to replace. 130 € placed at the door.

The problems it solves are:

1, battery. As it has a 5680 battery, it has a long-lasting wick. In one hour of use in full sun and maximum brightness it spends 8%. I estimate 10 to 15 hours of trouble-free battery life.

2, overheating. Its casing is made of solid aluminium and Kevlar. The metal case dissipates heat well. The manufacturer claims that it can work in extreme cold and extreme heat environments without problems.

3, Communication disturbances. As this phone is intended to replace a GPS it does not have a SIM card. He doesn't receive or send calls - except distress calls - and I haven't installed messaging for him. I have only installed the navigation and weather applications I need, no more. My usual mobile phone is still with me and is on the nav station providing Internet access to all the devices - which definitely solves the problem 4 - and is fully charged.

4, already solved... by the above.

5, The charging port is deeper and is better protected than that of conventional telephones. In fact, it uses a special longer micro-USB connector to avoid this type of problem. Anyway I prefer to exchange the phones - the inside out and vice versa - depending on how they are charged, although in roug conditions it will always be the rugged one.

I liked the result and that's why I wanted to share it with you. Especially for those who are thinking of something like that if it helps them.

[Image: IMG_20180522_120018_2.jpg]
As you can see it integrates very well with the rest of the electronics using an 8 € support and as the device has physical buttons apart from the screen buttons we can maximize the size of the screen - it is only 5 inches - and use it in difficult conditions with more ease which solves the problem number 6 quite easily.

Anyway.... I'm sorry about the long, long gig.  Angel


  New Twitter Node

Has anyone updated the Twitter node to V1.0.0 in node_red?

I couldn't update from the palette so tried using:

Code:
cd /home/pi/.node-red
npm install node-red-node-twitter@1.x


but still no luck.

I didn't want to try anything else from here: https://discourse.nodered.org/t/new-twit...quired/664
in case I stuffed something up!!

  OpenPlotter para no iniciados. Cont. del hilo de Perri
Posted by: pinguino - 06-10-2018, 05:05 PM - Forum: Español - Replies (63)

Decíamos ayer....

Como le comentaba a Sailoog en la PenguinPlotter alternativa me atreví a introducir algunos cambios.

Uno de los mas interesantes era la sustitución de Zygrib por XyGrib que es la que recoge el testigo y continua el desarrollo. 
En la PPlotter introduje la versión 0.0.1 de XyGrib pero hoy he logrado compilar la mas reciente la que esta a punto de salir la 1.0.99.

Como parece funcionar bien he comprimido la aplicación y la he subido al canal de Telegram. Quienquiera que este probando la PPLotter puede actualizarla simplemente descomprimiendo el zip y poniendo la carpeta que sale en la carpeta de usuario pi sustituyendo o renombrando si quiere conservar la otra versión, la carpeta con el mismo nombre -XyGrib- que esta en la de usuario pi.

Yo he probado a hacerla funcionar también en OpenPlotter y va bien pero antes hay que instalar unos paquetes para que funcione. Si alguno tiene interés, que lo diga y le indicaré como.

Si alguno tiene alguna duda respecto a Oplotter PPlotter o lo sucedido en la taberna que la plantee si lo desea.


If any non-Spanish speaking person has questions about why this thread is in Spanish they can ask for an explanation.

Best regards.


  [SOLVED] SPI MCP3008 not working in 1.0.0
Posted by: Saqqara - 06-10-2018, 04:26 PM - Forum: Bug Reports - Replies (6)

My connections are good. The SPI interface is enabled. I boot from a 0.17 SD card and it works. Put in v1 and it does not with same settings. I see it in signal k but 0 volts. With or without conversion through table.

Also, the word "aktiv" in this module shows in English translation, I assume this should say "active". It has been that way forever.

  sudo without password?
Posted by: Otoio - 06-08-2018, 08:15 PM - Forum: General discussion - Replies (1)

There is a configuration file for not asking password when pi acts as sudo (as su, properly).
I think it cannot be Raspbian's feature (the debians wouldn't do something like that, it would be considered a major crime  Wink )

Is it a OpenPlotter feature or configuration?
Which is the reason for that? yes, primarily not to ask for a password, but I mean if it might be a condition for other programs' well working or something like that.
If this file is deleted, would Openplotter  work ok?

Thanks
