Zipit Stuff

To add to this post, Mozzwald released Ubuntu for the Zipit the other day. It's always nice to have more userlands to choose from. It doesn't have a working GUI yet but if you are inclined you can add one fairly easily. The key selling point for this distro is that GCC is working finally so you can compile directly on the Zipit although it takes a long time for larger programs.

Any particularly cheap places you'd recommend to get this thing from?

Looks like something that could be worth playing around with.

There fairly hard to find out side of the US and Canada. With the EU having the restriction of hazardous substances directive means lead-based solder is a big no, no if you want to sell anything.

I just posted my serial modification to my blog and a disassembly guide for the Zipit Z2 if anyone is interested:

And I just completed it, sort of kinda modified. I use an external level shifter that I have kicking around that i used for interfacing with a Mastervolt unit back a year or so ago - It's almost as big as the zipit itself, but I wanted to prove the concept prior to actually building on a newish (to me) design. It's the rs232it from RE Smith:

Works a champ. Its a real rs232 port now avail up to 115.2k on ttyS2 and minicom talks through it. There is no hardware flow control (as there is no real UART).

My primary reason for wanting a real rs232 port is that i often am called upon to interface and debug with motors, generators, HVAC, lighting control, etc. We do vessel monitoring systems aboard luxury motor yachts. Laptops need external serial ports, and take up a lot of space and weight. ZipitZ2 fits literally in a pocket.

Uboot stuff looks really interesting, and I'm waiting for all the dust to settle down and hammer out some of the specifics and trouble before I jump into it.
