[David] put together this rather nice 1-wire barometer. An MPX4115 measures the pressure while an SMD DS2438 mounted to an 8 pin DIP socket provides the 1-wire interface. The writeup includes a nice description of the board layout and wiring, making this project accessible to just about anyone with a decent tip on their soldering iron.
