An article over at O’Reilly describes the Gumstix computer, a very small ARM based Linux machine. The systems themselves seem to be quite cheap compared to other embedded system development systems. Information on the sites seems to be a bit spotty with relation to how development tools are made available. Maybe it uses a completely stock gcc ARM compiler and instructions for building the cross compiler come with the board, I didn’t see that question answered directly in the FAQ. It is not an open source design, they aren’t planning to release schematics for the Gumstix systems. But like the author of the O’Reilly article I think the geolocation applications of a system like this are pretty interesting. Given that it runs on such low power in general, if that power supply can be made to last for a long time it would make a great geologging platform.
