Mini Board PC

writes "There's a product out called the 'Mighty
Might'. It's a SBC (Single Board Computer) that is the
size of a hard drive. It has IDE, FDE,IR, VGA, USB,
Parallel, Serial, Keyboard, Mouse, Network and LCD
controllers on board. The models range from a 486-16 to a
200 mhz Pentium. The 133 w/ 64 meg of ram costs about
$850." Bit pricey, but super cute.. maybe if it had wireless
ethernet.
Link on over to Industrial Control Links' PC-On-A-Stick. Now if only this were a P-III ;-)
There are probably a hundred companies that make these, and most are a *LOT* cheaper than this. I've seen systems that size at that power for $400, not $800.
Just do a search in yahoo for embedded PC. You'll find lots of them. Or you can look at some of the links on my autoLinux site at http://www.bangsplat.org/autolinux.
I seem to remember I linked to some there...
PCM-5820-E0A1 - This one looks damn cool. 3.5" SBC with audio, vga, 10/100 ethernet, IDE controller, single +5V power requirement, up to 140F so it can work without CPU fan... This sounds like the perfect board to make a portable MP3 player out of, except you need to write a Linux driver for the Cyrix CX 5530 PCI sound interface (I don't think Linux has one yet).
You might also need some power supply circuitry to get the proper power off of batteries and for your hard drive. Anybody know of any laptop sized IDE hard drives that use only 5V instead of 12V? Also, anybody got schematics for a 6V (four 1.5 AA batteries) -> 5V power regulation circuit?
I dunno about the rest of you, but I'm really tired of having to sit at home with my desktop to listen to all my favorite music. And I'm tired of waiting for Diamond/Creative Labs to get their act together and produce a serious portable MP3 player (and no, the Rio is not serious IMHO).
