Rapberry Pi's are being offered on ebay starting at £100

Sharks.

Pi's are priceless and worth every penny.

Lobster, how did you sort the HDMI problem?

4 for £5 on ebay (including delivery)
there was no problem with them - working fine

Happy for you, Lobster, and Iguleder, Pemasu and company will be happy, too that you are getting Squeeze'd.

Have not yet played with Squeeze
but boot up
is
login pi
password raspberry
startx
for desktop

Leaving that for now
- straight to desktop not a priority.

I am thinking very much of doing documentation here on the forum
or more likely here
http://puppylinux.info/topic/arm-puppy

Thanks for the Pussy info
I was really hoping we might have a Qemu ISO
. . . having me as a developer, is my last choice

I'll be doing my best to prepare our smarter dogs.
Early batches of Pi may be coming through the letter box this morning
If so . . . let us know

The speed issue:
Midori running slow - but connection speed is often more of an issue - so not to worry.
For those delving into the dark arts (aka programming) this is spot on.

My next tasks are to explore if I can write a bash script to download (apt-get mtpaint) Puppy essentials.

I also need to know how to change, output or remaster a modified Squeeze.
Any info on that welcome

gonna be grateful for any help developing this page:
http://puppylinux.org/wikka/PuppySchoolRaspberryPi

the PARM page is for Puppy on ARM
http://puppylinux.org/wikka/PARM

New one is for Puppy specifically on Rpi

Sausages and lemons [Lobsterian cussing/swearing]
Just checked out the ipad power supply again . . .

It has a USB and I have the USB to micro SD cable
it is rated as 5.1v and 2.1A

I thought it was 10v - I am sure I checked it out on the Apple site
- oh well, time to up medication to the red pills (only thing is I imagined those pills too)

I am told that 5.1v is acceptable for the Raspberry?
2.1A would be good.
Would have saved £6 for power supply yesterday
Would 5.1v caramelize the raspberry?

That should be sdc.

You mean I was only out by 1?

I used your suggestion rcrsn51
You are right

It worked and I was able to install to a 2GB SD card from Puppy and boot from that.

Why is it displaying sdc1 on screen (the parameter I used) and yet sdc is the correct input?

Lobster · #157 Post by **Lobster** » Mon 16 Apr 2012, 12:30

In Debian Squeeze
I need to be su to use apt-get or aptitude

Tried return (no password)
raspberry (it should be this surely)
and suse (I think that was for the previous debian not sure why)

None of those work - got to find the Squeeze password

Sugarpuffs and lemons [more cussing from the Lobsterian depths]

Any ideas/clues?

rcrsn51 · #158 Post by **rcrsn51** » Mon 16 Apr 2012, 12:43

Why is it displaying sdc1 on screen

Because the current structure on the card has one partition, which Puppy sees as sdc1.

But the dd command will write a new structure onto the card that contains several partitions. So dd must copy the image to the card starting at its root location - sdc.

from the previous post from pussy

The syntax for using dd to image a drive is:

dd if=<filename.img> of=/dev/sdX

Where <filename> is the USB image filename and the X in the /dev/sdX is the drive letter. Note you must specify the drive
NOT the partition on the drive (ie. /dev/sda not /dev/sda1) this is because the .img file contains partition info already.

sudo passwd

Then you can set root password.

Thanks guys this is the procedure I successfully used
to get mtpaint running.
Did not want to change the password.
There are quite a few terminals in Squeeze and I eventually used the first one available 'Lxterminal'

sudo su
(password = raspberry)
apt-get update
apt-get install mtpaint

mtpaint (as an example)
can then be run from the terminal

im glad that the Pi has analogue video output (i can use my TV!!) and USB port and a proper ethernet connector.

What springs to mind here is the potential to create a linux gaming platform similar to a console like the Xbox or PS2 etc. Consoles in the past have always had sucky CPU and RAM but good video chip, just like the Rasp Pi.
The Rasp Pi will be shipping with a case soon so it will even kind of look like a console.

after creating a small server / console pussy linux for this device, i will proceed to see just what selection of gaming software runs well on it and then release an OS that has the best ones all installed and working.

I have one of these thingies ordered and now its just a matter of time.

sickgut

hope you are not stressing.

I know about stress. My adrenals are maxed out just because a bit of hardware was doing strange things . . .

Basically the 5v 1000mA PSU does not have enough oomph (a technical term) to run the keyboard from the hub . . .

i seen a youtube vid showing the user is: pi and the pass is: raspberry

yes this is lame. WTF? would have made more sense to have user raspberry and pass pi.

Thanks for the heads up bud, i suspect that a usb hub that is powered will sort the problem out.

For the benefit of those reading the forum here yes there are two types of USB hubs. The normal type is non powered, its just a USB splitter kind of thing that turns one usb port into 4 or however many.

The second type is the powered type, its a usb splitter but also with its own power supply. These are more expensive ($14 compared to $4 on ebay for example)... but let you run USB devices without draining power from your motherboard.

I actually ran into this problem with my desktop computer believe it or not. Living in a very humid environment degrades the power supply gradually and after 10 years the 12 volt rails where supplying 11.5v and the 5 volt rails 4.8 volt and the 3.3 motherboard/ cpu voltage to 3.2v.....
when it was new, it supplied voltages slightly above the rating, now its below. When i attached an external 2.5" usb portable hdd with no separate power supply it would run fine but after a day or two it would error out and the hdd would go missing from the OS and it results in a reboot, when i attached another hdd like this then this issue happend every couple of hours and my usb mouse was spasmotic and would just switch off and switch back on all the time due to not enough power.

after buying a powered usb hub and running the mouse and hdd's from it, everythings fine and reliable again.

Personally i think people are better off with separate power for usb attachments than buying a more beefy power adaptor to run the rasp from to do the same thing.

Hope you get it sorted lobbie

(ps. i spose yall could get around the problem by running wireless attachments rather than normal wired ones as they usually have their own power via batteries etc. I personally hate anything wireless. The bible prophecy says wireless tech is the 666 devil. No it doesnt but i just like to say stuff like that to make wireless things to sound bad. I just dont think its healthy to have a microwave transmitter near you all day.)

dd and nano are the 2 greatest apps for linux of all time, i use:

dd if=/dev/zero of=/dev/sdc

on my usb stick every few days just because i can

I read about the powered USB hubs but for a USB keydrive and mouse, I seem to be able to use the unpowered.

I tried to apt-get some more programs
No Seamonkey, firefox or Opera - how do I get a listing of packages similar to what I am looking for or browsers?
I used something called aptitutde yesterday but I have no aptitude for it.

Inkscape seems the only program available but it took up too much space . . . que? I have a four gig SD card. Is the pi user space likely to be limited? Ah well, I purged and autocleaned barely knowing what I am up to but no luck.

I am off to find a simple bit of script to run from the command line.
I am using the command line more in the last couple of days than the previous year. If only I was more able.

I asked rpi to send Barry a Pi board - I hope they did. He is back tomorrow.

The Rpi is a fabulous pice of kit because of two expansion cables as well as pins to connect to stuff [stuff is a technical term]

Been sunny and rainy - sunny now - time to take the Raspberry Puppy board for a walk . . .

Look in the file /etc/apt/sources.list.

Look in the file /etc/apt/sources.list.

all the browsers are there, but debian has different names for them all:

iceweasel = firefox
iceape = seamonkey

so use apt-get update first, then try:

apt-get install iceweasel

there are other ice-browsers dunno what the other names are, there is some disagreement or licencing problem that debian had to work around or something. However, the iceweasel in the debian squeeze repo is version 3. something (this is how it is in the normal debain repos, dunno about ARM), firefox is version 11 now but the debian repos lag behind. However you may find that if you go to seamonkey website you can download the source and compile it.

Is midori the default browser in debian raspberry pi?

midori is by far the fastest loading and scores 100% on the html acid test, but the only drawback i can tell is it doesnt support java. (supports java script ofcause but not java.. they 2 different things).

Then you can set root password.

also sudo -i should give you root without need for password

not much in there
or in /etc/apt/sources.list.d

Yes it is. It was chosen because of its speed

Today I copied over a bash script - very simple
and ran it OK
Getting familiar with the hardware
and remembering any cli skills I may once have had.

gcc is in Squeeze
various editors - geany, leafpad - also python editors
