Title: Raspberry Pi
Post by: sirtetris on Mon, 24 September 2012, 12:31:05
First off: I know there are threads concerning the fact that someday there will be this thing called 'Raspberry Pi' (http://geekhack.org/index.php?topic=22014), the sale of the very first RPis (http://geekhack.org/index.php?topic=25618) and the actual start of sales/first batch (http://geekhack.org/index.php?topic=28030). Yet, I hope it's no problem to open a new thread concerning the Pi itself.

So: anyone else here got one? If so: what do you use it for? Did you create/buy a case?


Here's a picture of mine:

It's running Arch Linux, serves as an IRC "bouncer" (irssi runs on it and I connect via ssh), executes cronjobs, has a nginx webserver running and yeah ... has a Lego case. :3

I already ordered a second one and maybe will try the following with it: http://www.cl.cam.ac.uk/freshers/raspberrypi/tutorials/os/

I am considering buying one. Too sad that it dosn't run BSD.
FYI: It runs netbsd, but without support for internet.

Nice. I really like the Lego case

Lego case is the way to go for RaspPi and Arduino!  I like the pirate flags...nice touch!

Love the Lego case! Interesting use of minifigure legs in the structure lol.

Why hasn't anyone made a Lego keyboard case?

I've been thinking about getting one and running Arch Linux or the Raspbian (Debian for Raspberry Pi) distro to use as either storage, a torrent box (not for pirating), or possibly streaming music.

I like the PiBow case, but I have legos at home I can use.

I've also been thinking about getting one purely for a private email server for my family.

I'm also not sure if the power requirements are low enough but it might be usable as a solar powered computer.

Be aware when you use private mail servers, keeping the spammers away is usually not an easy task.

I've got one.  It's currently running raspbmc (tried openelec, didn't like it) and it's stuck behind the TV on XMBC duties.  Currently planning on buying a few more to go around the house.

Also re private mailservers, I've never found it hard, but then I run mailservers for a living, so I guess doing what I already know helps things out.

Yeah, that's just based on what i've read.
But I think you would need quite some gear and effort to get it running spam free.

I've got mine as a media center unit currently. Running the RaspBMC.
And it's installed in an adafruit case.
I ordered 5 and once the frenzy of friends was done, I have one left :(.

No gear at all, just a bit of reading and applying knowledge.  I wouldn't run one on a rpi tho.  You want a vm/vps for that.  I get mine from Bytemark (www.bytemark.co.uk).  Plonk debian on it and follow the tutorial at ispmail - http://workaround.org/ispmail/squeeze and you'll be up and running.  If you don't have any domains, use www.gandi.net as a domain registrar.  I started running my mailserver in about 2003 (pre my currnet linux job) and it helped in getting my current job as a Linux sysadmin.  The anti spam stuff isn't hard at all.  If you use postfix, then using postscreen, postgrey and spamassasin plus a couple of RBLs will sort you out for anti-spam.  If you're geeky enough to come on a site like Geekhack, then you're probably able to run your own mailserver if you want.

re write cycles, I really wouldn't worry about it, most cards have 1,000,000 write cycles, which means in real terms you have to be reading, writing and erasing data for about 3 years solid before you're likely to kill a card.  If you want to find out which app is polling the system when it's running, you just need to get a program that tells you which program is writing to which and you'll know.  But I really don't think it's worth worrying about.  SDHC cards are so cheap these days, replacing them every 3 years is not a biggie (and that's assuming constant usage).

As for why it uses an SD card?  I think it's cause they're small and don't take up much space.

I have one I was originally trying to use as a baby monitor.  But then I got bit by the USB issues.  Couldn't power a webcam or the wireless adapter (well, and have it actually work).  Tried using a hub, but when that was plugged in all USB went to pot, including the onboard NIC. :(  I ended up just using a laptop with a dead LCD, since I had the stuff and it was free.

After watching The IT Crowd, I got the idea to make something like "the internet", but with some toggles and buttons.  I got a nice project box I'm going to try to use, and some quality switches and doodads for it.  I'll probably use a couple Cherry blues or blacks I have with some relegendables.  Then I want to use it to monitor some stuff at work and blink lights and stuff.

The interesting thing to me so far is that it reminds me of what it was like using Linux years ago.  There is a noticeable delay in the time it takes to instantiate a process.  But it's kind of fun to play with, and it has me being thrifty with my shell scripts and writing some C again.

I want to use one as a media player with better audio outputs than most commercially available stuff.  Cram it in an old transistor radio or something similar and etc.

I thought about getting one and do some kind of a HTPC...don't know if it'll be able to do 720p or 1080p tho

Does 1080p with RaspBMC no problem and getting better by every release

raspbmc ++

Just make sure you get a decent remote as I still think the XBMC interface needs some slimming down.  Too many clicks to get to the simple job of playing a movie or mp3.
