Raspberry Pi

category: code [glöplog]
Great demo machine!

Fixed power
Open Source
OpenGL ES2.0 ( Pixel and Vertex Shaders! )
HDMI output
Extremely low price! $35
Too bad that the 3D driver isn't open source though

lol @ zdnet article:
The Raspberry Pi is a BBC Micro come-back tour and as likely to excite teens as Phil Collins getting back with Genesis.

@PauloFalcao: You're saying something, especially when considering that it is not even strictly necesarry to have any inputs in the machine to watch demos, you can just hook it up to your monitor/TV with a USB-plug in the other end and go.
kusma: I did note that above, but question is, does it need the data lines of USB to be active or can it work with power pin only?

Gargaj: For running as a stand-alone machine it just requires power.
The data lines only need to be used when you're controlling it from the host (i.e. "running android in a window on your desktop machine" etc..)
@Lord Graga, yap, probably you can make a bootable demo.
Bah, Farnell just bumped my order to the middle of May! :(

Subi: At least you got an ETA, I've just got an acknowledgement... :/

Not going to have enough time to play with it before Sundown at this rate!

If you already had a March/April delivery date and it's just been changed to May, the May date is an error.

Terrific job they're doing with the orders :(
By the time it takes them to normalize everything $35 + taxes will seem an high price to pay :(

Subi: you can just, you know, start crossdeveloping now and worry about porting it later :) (It's not like it's gonna be a particularly hard platform to develop for, it runs Debian after all.)

@Gargaj: Yeah, I'm using VirtualBox+Arch ATM. But nothing beats real hardware. :)

our real hardware can beat your real hardware

In case somebody isn't aware of that -> Besides the Raspberry PI there's lot's of nice (okay, a little bit more expensive, around 150 - 200 dollars) development boards based on ARM cpu's out there.

I guess most popular is the Beagleboard (ARM Cortex A8) and the Pandaboard (ARM Cortex A9). I got both of them running Risc OS and coding in good old BBC Basic/Inline ARM assembler :-)

Some enthusiast ported Risc OS to these platforms (http://www.riscosopen.org). It currently lacks of multi cpu core support and open gl, but I still love it. On the good side the BBC Basic Assembler includes now all the ARM VFP and ARM NEON commands (SSE-like extension) :-)

I ported iq's tunnel demo from his 1k/4k software frame work to assembler and at least I got something like 30 Frames/sec at 1024x768x32bit at 1 GHz on the Pandaboard.

Anybody coming back to good old Acorn times ;-) ?

€150 is very different from €40 including shipping + vat

any good demo yet?

xernobyl: so is 1gHz to to a few 100 or 128mb ram compared to more on the panda board (dont know how much).

You get what you pay for.

so, has anyone attempted to copy the raspberry with similliar parts, yet? or have you heard of homebrew attempts? sufficient mobile memory can be hard to come by and the assembly is tuff, i hear, but some nutter is bound to attempt that. imagine the joy of choosing one of the many arm procesors :D

If you want something inbetween the Beagle/Pandaboard, take a look at the Beaglebone.
• >700-MHz superscalar ARM Cortex™-A8
• 256-MB DDR2 RAM
• 1-port USB 2.0 host
• Integrated 10/100 Ethernet
• microSD slot and 2-GB microSD card with validation and demonstration image from the Angstrom Distribution
• USB 2.0 fl exible device port with ability to supply power
• On-board USB-to-serial/JTAG over shared USB device port
• 3.3-V 2× 46-pin peripheral with multiplexed LCD signals and battery-control expansion headers
• Board size: 3.4” × 2.1”

Ah, and ~80€ + shipping in Germany.

First orders are taken from Radiospares. I'm impatient to get mine.

It seems people are finally receiving the first orders.

1st orders from which seller?
