RasPi arrived

It got delivered today, I immediately connected it up, plugged in a SD card with minimal Raspbian image, and it works.

The powered hub powers the RPi and also provides lots of extra USB ports.

The next step is to build "Raspberry Puppy" in Woof ...I'm already onto it

RPI
Are you saying that you provide power through one USB port (max. 500 mA) going into the RPI? How many mA are the specifications for the RPI?

I have this setup. XBMC is running "like a charm".

Great news
I brought a Pi that has been languishing in a draw ever since as I have been waiting for a Puppy to put on it, thanks Barry!
There are a number of uses I can think of but having an always on desktop for my work rather than my power hungry quad core is top of the list.
I will try and help with testing if that's of any use when you have an iso

RasPi Picture to augment the diagram
Barry your page shows an excellent hand-drawn diagram.

And your picture in this blog thread shows a "working visual" of your diagram.

If you find it appropriate, you may want to add your Picture into that RasPi page as well.

It could be useful in making RasPi an elementary setup.

Happy 256mb campers
Hoping that what you build can also be used in the 256-MB model B.

Great job Barry! Will keep an eye on your exploits

7-port usb hub
Note that you need to have a "dumb" USB hub, that will feed the power straight through.

Also, I think that mine is very dumb, doesn't have individual current monitoring on each port. Thus, one port is enough to power the RPi, even if it needs more than 500mA.

And yes, the power adaptor must be rated at 2A. You can't believe what they say, either -- I tested a 1A supply awhile back, and I don't recall the exact figures but it wasn't capable of supplying 1A, nowhere near.

Regarding the Mbeat 7-port hub that I purchased, I also purchased another that I discovered in a shop, that looked almost identical -- however, the power adaptor was physically smaller even though rated the same, and the cables were thinner.

I need to edit that web page, as only the first version of the RPi board has those polyfuses.

RPi suggestion
I think this is a good idea.

I went through the rigmorale of installing slackwarearm-14.0 on my pi about six months back. As you Barry would probably know slackware make you "do it yourself", that is, prepare the disk with fdisk, format, install. Yeah, you can do it the easy way, there are some images floating around but the point is not the way it's installed but the end result.

Stuart Winter (aka dr.mozes), the slackwarearm maintainer, suggests partitioning with the small FAT partition at the start of the SD card (as usual), then the swap, then the ext(2,3,4 or even f2fs) filesystem at the end. The point is, if you want to migrate to a bigger card then you only need resize 1 partition.

Now my suggestion is exactly that. When you build your next empty SD card image could you make it such that swap is before the main FS? Then a user only needs to stretch the main FS if they want to load it onto a bigger card than the image. You could then ship just a 2GB (yes I know compressed there would be very little difference in size) image for those who can't for whatever reason use a bigger card.

Awesome! :-)
I can't wait to put a fully functioning puppy on my Raspberry Pi. It's been languishing in a corner for a while now.

2 GB size

The standard size of the image supplied by
the Raspberry pi people is 2 GB, then compressed.

Downloads:
This page contains links to SD card images for various operating system distributions. The minimum size SD card you can use is 2GB, but it is recommended to get a 4GB SD card or above.

RPi model indication
Since there are only a few models of RPi around (i.e. a few model Bs and one Model A) it would be fairly easy to detect number of USB ports, presence or absence of ethernet HW and size of RAM. You could then indicate this on the desktop with an icon or a scrolling banner or text label.

The combination of a RPi and Puppy is probably going to be very attractive to the "tinkerers" of this world, so I'm guessing they'll be swapping cards and boards with abandon.

RPi
I look forward to when I can run my RPi with Puppy on it. I tried the first Puppy Pi release, but it ran slower than Rasberian for me. Not sure why, I didnt do much testing with it because of how slow it was. (Model B - 512mb)

The Pi works well with my LapDock though

ARM-ed with a touchscreen
I was just reviewing the diagram and saw

Here's an idea for this ARM following. It you had a Touchscreen monitor, you would NOT only need the following for your ARM installation to be "use-able" for simple desktop needs
[list][*]a power supply that has a mini-USB plug
[*]a HDMI cable from the ARM to the monitor[/list]

Something so simple as this could have enormous benefit in some/many home uses.

Understanding some of us old timers would be hard-pressed to pry our hands away from the keyboard-mouse, I ask: "Is there something missing in that simple configuration for some home use?"

This idea does NOT need a reply. Its only for consideration.

Correction: ARM-ed with a touchscreen
There's a typo in the above. The word "NOT" should not have appeared. Below is correction to the post

Puppy on arm
What we want is puppy on tablet. Tablets suit my horizontal surfing posture. This one look interesting. http://www.cnx-software.com/2013/06/06/wm8880-mid-tablet-is-now-available-for-59/#comments but there are reviews and links to more tablets and Dongles than you can poke a stick at there at that site.

Raspberry Puppy progress
A progress report:

I have built "Raspberry Puppy" from Raspbian DEBs in Woof, and booted up in the RPi.

It gets to the commandline OK, but Xorg segfaults. So, I have try and figure out why.

Right now though, I am diverted, working on something else.
