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:

I'm bringing up the topic because I might get a Raspberry PI model B rev. 1 (the one with 256Mb) with case included at a good price. I don't mind about the memory because my intention is the typical one of torrent manager and a small web server without even MySQL and all without a graphical environment and controlled by SSH.

I already have SD cards and the problem is that the USB power adapters I have only go up to 650mA the most (less the one from the mobile, but I can't do without it) while for the gadget I've read that 700mA are needed and I don't know if then it will work for me. In the worst case, I'll buy a cheap one. For the first configurations I will use the HDMI cable from the WD TV Live Streaming and any USB keyboard. I also have a mini wifi adapter that Ubuntu and Mageia detect, but we'll see if Raspbian does it.

It's the Hard2mano offer, right? I've been tempted to grab it, but I've already given in to many whims this January to continue with the loose wallet policy :ugly:

You'll let us know how it goes

Best regards

Shhhhh… ;D

The opposite has happened to me, I've had very few expenses in January, and not much at Christmas either, so I'm going to dive into the topic.

[Sylver]

Oops… I haven't said anything

What a success, who would you be... From the monitor I have felt a curious tremble xD
Good luck and I hope you show it to us soon!

Claro, I'll show you the little thing if we continue with the topic. The question is whether Cobito is preparing his guide, because I could put something, but not much because the use at the moment is very specific.

[deeiivid]

I've also been super tempted by it, because I download torrents everywhere and I'm not very eco-friendly with the i7 and gtx295 and I also don't want to have the air running all day long.

I also have an atom but it works when it wants…

But above all, I'm waiting for the new BOOK by Cobito about the raspberry PI to finally tempt me to buy one. :ugly:

My thing is that it's an obsession with low consumption. Of all my computers the one that consumes the most is around 31w at rest (I've removed the graphics because I don't use it lately), and the Raspberry will eat them all with potatoes, hehe.

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...

@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'.

[cobito]

I can only think of two things:
· That something has corrupted on the SD card (the most I can think of is that you do an apt-get upgrade and an rpi-update).
· That the Raspi is not receiving adequate power (plug it in without a network cable, no HDMI or USB and when it has finished charging, connect the network cable and try an SSH connection).
