Linux Physical Computing...
I'm putting it here as a curiosity... but it may be something good to pay attention...

A demo showing RaspberryPI doing "physical computing" stuff... which may be translated as "Linux Physical Software"...





I like to list here the "why" I think RaspberryPI is something that is worth paying attention to...

d) Credit Card Size
c) U$25 Complete Computer
b) ARM powered
a) FULL Linux Computer (Linux, GNU, OSS...)

Here is the site of the Raspberry PI Foundation: http://www.raspberrypi.org/

Unfortunately it's a rather "closed" board. No schematics. Not even details and timings of the processor and its I/Os. As they are are also a month or two at least behind schedule and say only one per customer initially (when they finally ship) this means even longer delays for add-on hardware.

Summary: wait and see.

RE: Linux Physical Computing...
I've also been following the RPi with interest for some time.

HOWEVER - and I do agree with Valter 100% as to the drivers of its success - I believe it and the Pinguino are boards targeted at different users/applications.

If you want to run Linux on Pinguino, have a look at http://www.retrobsd.com.

Already supports at least 1 Pinguino from Olimex, and it can't be such a nigthmare to port to others...

Actually, I started looking at the Pinguino (coming from Arduino's and knowing about the RPi) precisely because I came to the conclusion that for "physical computing" its additional power means additional complication for real-world-sensing-and-actuating applications.

IMHO, the RPi is targeted more at the "media"/"classical IT" stuff, the Pinguino for those wanting an "Arduino on steroids", with more flexibility in the platform

retrobsd's a bit big for the Pinguino!

I don't recall anyone saying they wanted or expected Linux on a Pinguino. But when chips have even more flash & RAM...

Pingotg - I beg to disagree, at least when targeting Pinguino32 - Retrobsd was targeted specifically at the PIC32 platform, and the 795 at that.

Have a look at e.g http://code.google.com/p/retrobsd/wiki/B...kfun_UBW32

As far as the 8-bit versions go, I'd have to dig in and see - I doubt that RetroBSD will "fit" but keep in mind Unix first came out in *1969* (assembler version) and C version in 1973. So probably impossible here, but impossible is a strong word (Yes, please someone prove me wrong!)

Yes but the 795 has 512K flash and 128K RAM. Pinguino 32 is only 32K RAM!

Tell me about it, I first installed 6th Edition... but the machine was not so small as a Pinguino32.

RE: Linux Physical Computing...
Yes and No - See http://www.olimex.com/dev/pic32-t795.html

(Possible, it is. Desirable? Unsure)

Cheers!

I know the board - it's been mentioned here before - but it's not a Pinguino32.
