Muahahaahaha!!! ¡¡Ya la tengo funcionando!!

Nada más abrirla he empezado a trastear y creía que ya la había roto :llorar: Pero no! :ugly:

Que bonito se ve todo, cuantas opciones, cuantas posibilidades. Creo que voy a llorar.

Por cierto, ¡no conectéis un adaptador HDMI-VGA a pelo que se puede quemar la raspi!! Ya explicaré cómo modificarlo para que funcione de forma segura.

En dos meses tendréis una review en profundidad :fumeta:

Con ganas de ver ese tutorial review, y si cobito dice en profundidad preparad una tarde de lectura XD.

Subo el tema porque es posible que consiga una Raspberry PI modelo B rev. 1 (la de 256Mb) con caja incluida a buen precio. No me importa lo de la memoria porque mi intención es la típica de gestor de torrents y un pequeño servidor web sin tan siquiera MySQL y todo sin entorno gráfico y controlado por SSH.

Tarjetas SD ya tengo y la pena es que los adaptadores de corriente para USB que tengo se quedan en 650mA el que más (menos el del móvil, pero no puedo prescindir de el) mientras que para el chismillo he leido que se necesitan 700mA y no se si entonces me valdrá. A las malas me compro uno baratillo. Para las primeras configuraiciones usaré el cable HDMI del WD TV Live Streaming y un teclado USB cualquiera. También dispongo de un mini adaptador wifi que me detectan Ubuntu y Mageia, pero veremos si lo hace Raspbian.

Es la ofertita de Hard2mano ¿verdad? Yo he estado tentado a pillarla, pero ya se me han ido muchos caprichos este enero como para seguir con la política de cartera floja :ugly:

Ya nos contarás qué tal

Shhhhh… ;D

A mí me ha pasado lo contrario, en Enero he tenido poquísimos gastos, y en navidades poca cosa también, así que voy a lanzarme al tema.

Ups… no he dicho nada

Vaya éxito, quién fuese tú... Yo desde el monitor he sentido un tembleque curioso xD
¡Suerte y espero que nos la enseñes pronto!

Claro, ya os enseñare el bichillo si sigue adelante al tema. Lo que no se es si Cobito tiene en preparación su guía, porque yo podría poner algo, pero poca cosa porque el uso de momento es muy concreto.

Yo tambien he estado super tentado con ella, porque descargo torrents por doquier y no soy muy eco-energetico con el i7 y la gtx295 y tampoco quiero tener el air todo el dia dandole al tema.

También tengo un atom pero va cuando quiere…

Pero sobretodo, estoy esperando al nuevo LIBRO de Cobito sobre las raspberry PI para que acabe de tentarme comprar una. :ugly:

Lo mío es que es una obsesión con el bajo consumo. De todos mis ordenadores el que mas consume ronda los 31w en reposo (le he quitado la gráfica porque no la uso últimamente), y el Raspberry se los va a comer a todos con patatas, jeje.

I'm back online because if I edit you won't even notice I've already received the Raspberry Pi, but I won't be able to tinker with it until tomorrow because I don't have an HDMI cable here. My question is about the external hard drive and its power supply. I'd like to avoid a self-powered USB hub, so I was thinking of installing Raspbian first, setting up SSH and then configuring it over the network without the keyboard and connecting one of the external 2.5" USB drives I have using a Y-cable that already comes with the two USB ports of the little gadget. Do you think it will be able to supply enough current? I imagine it will also depend on the power supply I put on it, 1 amp or higher?

@Yorus:

Refloto de nuevo porque si edito ni os dais cuenta

Ya me ha llegado la Raspberry Pi, pero hasta mañana no podré trastearla porque aquí no tengo cable HDMI.

Mi pregunta viene por el tema del disco duro externo y su alimentación. Me gustaría prescindir de un hub USB autoalimentado, por lo que pensaba en instalar primero Raspbian, configurar SSH y despues ya configurarlo a través de la red prescindiendo del teclado y conectar uno de los discos USB 2,5" externo que tengo mediante un cable USB en 'Y' que ya trae a los dos puertos USB del bichito, ¿creeis que será capaz de suministrarle suficiente corriente?. Imagino que también dependerá del alimentador que le ponga, ¿de 1 amperio hacia arriba?

Hola Yorus, mira a ver si consigues que te funcione el HD solo alimentado con el USB, pero me da que no…

Yo de todas formas, estoy contento con el HUB USB autoalimentado... Total, enchufo la rasPi y el disco USB ahi, y solo tengo un enchufe ocupado. Así que excepto por el mínimo espacio que ocupa el HUB no veo necesidad de quitarlo.

Ya dirás si te funciona, pero me da que no va a ser demasiado estable...

Saludos

@psgonza:

Hello Yorus, see if you can get the HD to work just powered by the USB, but I think you won't…

Anyway, I'm happy with the self-powered USB HUB... I just plug in the rasPi and the USB drive there, and I only have one plug occupied. So except for the minimal space the HUB takes up, I don't see a need to remove it.

Let me know if it works for you, but I think it won't be very stable...

Regards

Well, anyway it doesn't matter much, since I have to get a power adapter for the Raspberry and I've seen some with two USB ports and then you just plug in the cable you need (microUSB for the gadget and mini-USB for the hard drive). What I want is for everything to be as tidy as possible, but I still have to study it.

I'm already installing Raspbian, which on top of being a Debian on the distro's page there's a step-by-step guide for the clumsy

[cobito]

First of all, the guide I was working on is about to come out of the oven.

Regarding the hard drive query, the answer is a flat-out no. The Raspi consumes a lot of current by itself and the USB controller doesn't give much of itself if it doesn't have assistance.

On the other hand, before buying a USB hub, make sure it's compatible, because there are a good number of models that give instability problems or that simply don't work. It's a bit of a thorny issue.

I have mine working with a 2.5" 500 gb drive connected to a 3.5" enclosure that powers it. From that enclosure, I've taken a couple of cables for the 5V power supply to the Raspberry Pi, so that the 3.5" enclosure has become a raspi + 500 gb drive all powered by a single power supply: that of the enclosure.

[Yorus]

Thanks for the info. At the moment what I have planned is to get a power strip that Lidl is advertising starting from the 25th and that has 4 lines of normal power and 2 USB ports with 2100mA, so it will probably work for the setup and to have the router connected and a few other things I have in that area of the house (floor lamp, landline phone and a clock).

Edit:

It's curious, but I can't connect the hard drive even with additional power.

My drive has the USB for data and another one for cases where the power is not enough in the form of a 'Y', and I've tried connecting the extra USB to a adapter that I used to be able to see the contents of the drive on my TV (which also doesn't give enough power) and not even the motor of the drive moves. I've also tried with that connector on the USB 3.0 of the laptop and on the hub with power supply and I still can't get anything.

Edit 2:

What a way to complicate my life, I was using the USB hub to only give extra power to the drive instead of plugging everything into the hub and the hub into the Raspberry :ugly:. Everything is working now, with transmission-daemon installed although I have to check the permissions of the drive. The next thing will be to share via NFS or Samba and the web server.

[Yorus]

I'm not sure if I should put this here or in the guide branch, but well, I choose here for now.

I brought the Raspberry to continue setting things up and I don't have a monitor next to the router and the laptop. The thing is that I went to mess with it and I couldn't connect via SSH. I connected it for a moment to the TV without a network or keyboard and I see that it stays for a good while where it is supposed to load precisely the SSH server, and after a couple of minutes it goes to login. Then I connected it again to the router and it continues to reject the connection (with Putty, here I have Win7). I also can't connect to the transmission-daemon but there is ping.

Anyway, I'll have to see if it's something to do with the network configuration...

[cobito]

Perhaps an IP conflict?

[Yorus]

@cobito:

¿Quizás un conflicto de IPs?

No, although just in case I have also set the laptop to a static IP and restarted the router, but nothing is working.

[cobito]

I find it strange that it doesn't accept calls from SSH and not from the transmission daemon either. What were you doing just before this happened to you?

[Yorus]

I think the last thing I did was a transmission test a week ago, when I was trying to put the hard drive and it ended up working for me even though it gave me an error when I went to save the downloaded file (a 2Mb PDF), but it was a matter of permissions to the disk or the directory where it is mounted. After that I turned it off with'shutdown -h now'.
