I am new to all of this embedded stuff. I am looking for a very small embedded computer that will load Linux and run off some batteries.
Its needs an IDE for a 2.5 Hard Drive or a 1.8 zif and an sd card loader.
I want to move files from the hd to the sd card or del them off the sd but not the hd. Also need a very small lcd screen to see what I am doing.
And a few buttons but first a need the hardware.
Can this be done?
Has this been done?
Thank you
Sure. All you need is a PC laptop.

A netbook with Ubuntu loaded could run you under $300
Have a look at the Gumstix.

Linux, IDE hard drives is n embedded.
80%+ embedded systems don't use an RTOS let alone something as large as linux.You don't need an OS for that. Just a file system.
Look at some of the NXP ARM7 MCU with built in LCD controller (Zoom/logic PD kits)
You won't need a hard disk

Under normal circumstances, but during elections it is 150% of statistics are pure bunkum.

That doesn't apply for American elections. There the statistics are
91.33813489% correct - it's the official counts that are pure bunkum...
Does that include the hanging chads and dimpled chads?

I was thinking more of the electronic voting machines, with their accidental or intentional tallying errors. In a number of American elections, statistical estimations based on the exit polls have given more believable results than the official tallies.
If you want to start a real argument about statistics, raise the subject of accuracy of U.S. census numbers.
Ignoring the noise from the other replies... Look at the Beagle Board. Open source hw design, board is $150 from Digikey and it has linux ports. Not to mention it is a 600 MHz ARM Cortex A8 superscalar processor with a TI 6400 series DSP on board. Look at beagleboard.org.
Cheap, embedded, fun (?)

Since I have heard about the beagle board, I have seen no stock anywhere at any time. Digikey does not have stock at this time. Has anyone been able to actually purchase this board ?

Is there something the size of a ipod with a sd or micro sd That can transfer files to and from the ipod like hard drive.
Is it sold anywhere but Digikey? Digikey shows a ship date of
11/30/2008... I guess there are problems with production. The FAQ says something about Digikey not handling partial shipments (I assume they mean from the supplier, not the buyer) so that the inventory does not show up. That seems very odd...I am impressed with how the project is being run. Although a lot of things are "in the works", the information is amazingly available. Usually it is just the opposite, it is amazingly hard to find info on open source projects.
BTW, one thing I can't find is the Gerber files. I thought I saw a mention about them being available, but no mention of where to get them.
BTW, while digging around, version C of the board will have more functionality working, some of which may be important...
Revision C is same as revision B except:
Note: Revision C is expected Q1 2009. There are some early revision C prototypes out there, but they still seem to have USB host issue.

Beagle seems to have Linux sort of working but not quite.
The FriendlyARM Mini2440 is 400 MHz and 10x10cm (king size cigarette) and the Linux drivers and Qtopia work for everything including several LCD sizes and standard camera input. Comes with source and images ready to load. Look here for specs.
or just search ARM9 on eBay. He has a good price of $140 with shipping, I have them at $149 + $8 shipping and English versions of most docs and apps. If I ever figure out all the CSS and PHP and templates and themes, you will be able to see them on andahammer.com

Bizarre, I was using WiFi at Paneras and andahammer.com is blocked by sonicwall.com because of "weapons"! I submitted a request for review.
Do you know what that is all about?

Depending on the strictness of the filter, it might make sense. Archived material from the site would show that I used it for an organic rust remover used by law enforcement to clean rusted guns without destroying serial numbers, or anything else - iron oxide is the only thing it will touch. I also had a similar product described in detail for carbon and fouling removal from black powder arms but it is bought almost exclusively by the US Army for cleaning those organ pipe firing simulators you see mounted on tanks. They use a black powder charge and this stuff saves them a lot of time.
They both have very low civilian sales so I offered the site and host when we decided to launch the ARM board business, which is something I have been thinking about for at least 10 years.
