¡Beinvenidos Javier!

I would love it if you would make improvements to our Spanish translations! I used the free online stuff, figuring it was a good start and that someone fluent and interested, like you, would make it better. Not just the Ayudar page, but other stuff on Category:Español as well. And I'm very open to changing the titles of pages as well, if you've got some better ideas.

Thanks so much for your offer. I hope we see you around a fair bit. And feel free to ping me about anything.

Gracias

Hola Javier,

Gracias para tus cambios a la pagina - Help:Ayudar a los conceptos básicos. Tus cambios son muy excelente. Continúe, por favor, estar BOLD. Si tu tienes preguntas, me pidas a User_talk:Lonny. Lo siento - mi espanol no esta bien, y tu ingles es perfecto (creo que), pero mi gusto tratar.

I posted a reply at User_talk:Lonny#hi... I probably should have posted it here. Sorry, --Lonny 01:01, 24 November 2007 (PST)

Welcome!

Great to have you here - really appreciate your work on the Spanish pages! --Chriswaterguy · talk 07:35, 19 November 2007 (PST)

19 VDC request

From my user page:

:) Sorry, I didn't notice you answered me back here. Thanks a lot. As soon as I have time I will be looking to all this material. You also can ask me for translating something you consider of high relevance.

I think the priority is currently on the help pages, and some of the mission/site description pages.

By the way, at the moment I live in Zürich. I was thinking of using this website to calculate the inclination and orientation of the modules.

That sounds good.

I will ask you my first question: do you know some schematics to make your own DC-DC 12 to 19 volts converter? I want to build one but until now I didn't find anyone in internet. --Javier Carro 04:44, 24 November 2007 (PST)

I can help you with this question, but first I would like to take a step back and ask what the application is. It sounds like it is for a laptop from a car, but if you can tell me the voltage source I may be able to help brainstorm a better solution. Making 19 volts DC from 12 volts DC is difficult. That difficulty arises because AC is very easy to transform due to its oscillating voltage/current, but DC has a even voltage not allowing us to take advantage of a changing electromagnetic field. Therefore stepping up DC requires either DC -> Transformer -> Rectifier or complex circuitry. Let me know what the case is - 240VAC, 120VAC or 12VDC source and what type of load it needs to run and we will continue this design.

Hasta pronto, --Lonny 19:23, 24 November 2007 (PST)

You are right. It is for a laptop. I want to charge the laptop with the deep cycle solar battery of my future pv system. I was thinking to use 12V battery/-ies (though I see it may be more reasonable to use a higher voltage). I thought that converting the 12V DC into 19v would be much more energy efficient than using an inverter DC>AC to charge the laptop via the transformer we connect to the grid. In Switzerland we use 230VAC 50Hz in the grid. Anyway, I will begin soon a subpage where I/we can write ideas about the pv project in a more systematic way. --Javier Carro 22:50, 24 November 2007 (PST)
