This project is a 5 day barometric pressure recorder. It uses a graphic LCD to display previous measurements. It also uses a version of the 18X internal timer described by Hippy to identify hour-long intervals. And there's a nifty device store each measurement in half a byte, to save on memory usage.
The LCD and pressure transducer make this quite an expensive project but it's useful for the weather-obsessed.

ps Apologies for loading the program as a pdf; it's too big to load as .bas, sorry.
