It is now for me too, so it's not just your routing. Got me concerned
because we (Sparkfun and Budget Robotics) use the same Web host
provider. Or at least we used to. My site is still up, and there's comes
and goes. Might just be their box.

Yes, they do good work. And it's generally inexpensive. We need more
good, inexpensive stuff!

Unfortunately, their MP3 breakout board is currently out of stock, but
the DOSonChip and MP3 board would make a good pair for playing
sound/music/effects on a bot. OTOH, the price together is a bit high.
They also do a VS1002 MP3/SD module, and the Rogue Robotics uMP3 board
is a good option for those going in that direction. Choices, choices...

Thanks Gary, Bob, Fleming, and Gordon.

My Spark Fun connection is timing out right now, but do these guys do 
great work, or what?

This chip is also available on a finished product, with Flash card
electronics, holder, etc., at Sparkfun.com. About half the cost of the
Chipdos dev board, but also without the RS232 (TTL serial only).

Try this:

Fat32/16 on a SD/MMC card, with RS232 or SPI interface

Like this?

thanks Ulf and Jouka,

I now have many good leads to check, and decide which direction to go.

You might want to consider the AT45DBxxx series of dataflash.
This has an SPI interface and SMALL sectors (up to 1 kB).
The advantage of small sectors is that file system typically do not need
garbage collection (or it is simplified).
The pages have "extra bytes" allowing erase count and other things useable
in a flash file system.
The devices start at 1 Mbit and go up to 64 Mbit in pin compatible 8 pin 
packages.
Larger memories are in development.

You can also get 16/34/64 Mbit in MMC like Flash card packages,
so add an MMC connector to your board and you are in good shape.

Look here

This is not only a Usb Stick but also a kind of " Serial Stick".

Yes, http://www.st.com/stonline/books/ascii/docs/10987.htm

I'll go have a read, thanks

Maybe the M25P64 from ST ?
