[Novalug] Raspberry Pi

[Jason Kohles]

Comparing Arduino or Gadgeteer to the Raspberry Pi is a stretch.  They are
only similar in that they all contain microcontrollers (if you can say
that the Raspberry Pi is similar to the Arduino, then you can equally say
that it is similar to my toaster).

Here is a quick little comparison of the three:

Platform          Processor                 Cost
----------------- ------------------------- -------
Raspberry Pi      700 MHz ARM11             $35
Arduino Uno       16 MHz Atmel ATmega 328   $50
Gadgeteer         75 MHz ARM7               $100+

And then if you start listing the additional features you get for that
cost, the Arduino gives you stuff like serial ports and I/O pins, the
Gadgeteer gives you multiple interfaces to other types of Gadgeteer
modules, the Raspberry Pi includes 256MB of RAM, Ethernet, GPU, SD Card
Slot, USB Host, Audio and Video (including HDMI), and it runs Linux, so
you can just use it out of the box, you don't have to compile your own
code to upload to it..

Frankly, I think the Raspberry Pi is going to eat Arduino's lunch.  It's a
significantly more flexible platform that runs an actual operating system,
and for half the cost of an Arduino..

There are plenty of open source projects similar to .NET Gadgeteer, the
reason they aren't as popular as Arduino is that by getting less wiring
and soldering, you are trading that convenience for cash.  The
"plug-together" systems are always more expensive.

As others have pointed out,
the inexpensive $25/$35 computer Raspberry Pi,
now starting production.

Doesn't sound too much different
than the present fad Arduino.

I'd like to suggest that not to lose
site of a product that is easier for
software people to proto/build/fiddle
with, that is not linux compatible:
that is the ".NET Gadgeteer"-
a MS dot NET compatible product.
Haven't looked at mono compatibility.


It has much less actual wiring/soldering,
( standard wiring cables ) and
has a "standard" "open" CLR. And the
processing is in a sense more "distributed".
Works directly with Visual Studio.
The demo I saw was impressive.

There's a shortage of technical workers for jobs that don't exist yet.
