Thumbs up raspberry pi anyone?

I came across a product announcement for the Raspberry Pi in one of my hobbyist mags. At $35 it is well within my screwing around that will probably never go anywhere budget.

It just so happens that I have that same budget!

I would like to get one of these myself with the intentions of building something awesome, like a self aware something. Realistically it will sit neglected in the tech graveyard that is my office closet. It can keep my old computers and paintball guns company, collecting dust.

I have some pre-ordered, quite early, so I'll be getting news of a delivery date soon. I've been keeping an eye on this for some time, so I'll let you guys know how it goes when it arrives. I have pre-orders with both RS components and Farnell.

Bare in mind that you do need some other equipment to use the device. Like a micro-USB power supply (not mini), HDMI, Class 4 or Class 6 SD card, as well as keyboard and mouse. So it's not exactly $35. Plus there is shipping and tax, so it's closer to $50.

There are several Linux distributions you can get, Debian Squeeze being the main one at the moment. There is a Fedora Remix in the works, it was released but it has a lot of bugs.

Performance isn't terribly great, but that's not the point. But the dev community in the forum is already starting, things like NAS and even a media streamer (that will take more time due to lack of proper GPU support at the moment).

Yeah, I'm quite excited about this...

I'm going to get one so it can play ASCII porn 24/7.

I'm interested in one, but haven't ordered yet. The whole production delays are contributing to my confusion and, I must confess, suspicion. It wouldn't be the first time I left myself entangled in great promises and ended up with empty hands. Anyone who went through the Pandora handheld will know exactly what I'm talking about. I've been waiting for mine for two years now.

Anyways, I'm really interested in one to experiment and build my own small NAT controller.
And house alarm and camera control system could also possible be in my agenda. The NAT could be managed without developing any software and just taking advantage of the existing solutions. The home security device however would require me to program.

interview with the founder of Raspberry Pi

I only browsed thru that conversation for the moment, but it sounds like lead time will be a while.

And, in an almost pouring gas on the fire experience(for those of us who no resistance for tech gadgets as this), that Arduino sounds quite interesting also.

My RPi has been dispatched and will be here in the next couple days. Time to start downloading some distros...

Talk profusely about your experience! Curious minds need to know.

It's arrived!! So I ripped open the packaging, giggled a bit, saw the size, then started to take photos....



Yup... It's REALLY small. Anyway, I proceeded to plug things in with a rather large assortment of cables, then balanced it precariously on a glass.



The SD card I had ready wasn't working properly, something to do with the bootloader, known issue, etc etc, got a different SD card and things started working. Well mostly, The HDMI cable I had plugged in wasn't working properly and blacks appeared red... (no clue). So I swapped out the HDMI cable and I'm back in business.



Woot!! Username = pi, password = raspberry, then I'm at the Debian CLI. It's ALIVE!! Type in "startx" to start the x server for some GUI action and all is well. Made sure network cable was attached, loaded up Midori web browser, shuffled over to a certain website for some shameless promotion... and... yeah, that's all I've done so far.



It's now late, I need to sleep. I'll be experimenting away tomorrow, but on a different monitor and a more permanent setup. Maybe get some media playback, SSH working, then I'll see how things go from there.

Raspberry Pi's do exist!

I've been busy experimenting away. Not got anything major working, but I've been working on sorting out the basics (sort of). I have SSH working so I can remote in. I also have VNC working so I can remote GUI in. It's setup with Hexxeh's RPi update utility (due to a difference in Debian squeeze distro and the RPi distro). I've manged to resize the filesystem (while it was live) from the standard 2GB to the full 16GB on the SD card.

VLC player is installed. Browsing sites with Midori. I'll be installing a number of other applications later. I'll try Chromium out later and LibreOffice, see how they handle under 256MB RAM, lol.

One thing i will make clear is that this is not a fast device, mainly because of no GPU acceleration. I'll record a video or something later of me remoting in and launching a few applications.

I May try out the NAS solution that people have been developing later, since I have an external hard drive lying around i need to do some backups too. If there's anything people want me to try, let me know (just be aware I'm a relative noob to Linux, but since I've been playing around a lot with apt-get and filesystem resizing, things are improving).


The following is basically a list of commands that need to be done for me to get this thing working. The SSH setup needs to be done on the actual RPi itself, once that is setup, you can then do the rest of it via remote. I'm a Windows user, so I end up using PuTTY for SSH and TightVNC for VNC.

Code:
###  Enable SSH ###

sudo bash

ssh-keygen

enter enter enter

ls /root/.ssh

service ssh start

service ssh status

update-rc.d ssh defaults

shutdown -r now


### RPi update from Hexxeh ###

sudo bash

apt-get update

apt-get install ca-certificates

wget http://goo.gl/1BOfJ -O /usr/bin/rpi-update && chmod +x /usr/bin/rpi-update

apt-get install git-core

rpi-update

shutdown -r now


### Expand file system ###

sudo fdisk -cu /dev/mmcblk0
p
d, 3
d, 2
n p 2
157696
[enter]
w

sudo shutdown -r now

sudo resize2fs /dev/mmcblk0p2

df -h


### Install and start VNC ###

sudo bash

apt-get install tightvncserver

password
viewer=n

vncserver :1 -geometry 1280x1024 -depth 24
A few things I'll point out. The Debian default User=pi and Password=raspberry. There is no root password, so you can either set one via "sudo passwd root" and enter a password twice, then "su root" to switch to root, or use 'sudo bash' which switches.

If you are using the RPi direct, you can start the GUI by typing "startx".

If you want to remote into the RPi via an external connection (internet), you need to enable port forwarding if on a NAT router. TCP> Port: 22 for SSH and TCP> Port: 5900-5901 for VCN.

Sounds like you are having fun

I'd be interested to know if 1080p or even 720p HD video plays right out of the box when you install VLC. The lack of GPU acceleration might make that a little difficult, but it's supposed to handle it.
