Hi Jim:

   I have a full-blown weather station running on my TINI - it supports 
an unlimited number of wind, temp, humidity, solar, lightning, snowfall, 
and rain sensors.  It also performs automatic uploads to CWOP, Weather 
Underground, and APRS packets to an attached TNC.  The system is written 
in Java, and has been running continuously for three years now.

   I started writing an article about the system, which you can find at 
http://www.mulveyfamily.com/weather/tini/article/ , along with some 
pictures.  I suggest looking at the .doc version, which is Microsoft 
Word format.  The weather station itself is at 
http://weather.mulveyfamily.com .

   The article is still incomplete, but will give you an idea of what 
can be done with the TINI.  It goes way beyond what you're asking, since 
it essentially replaces the T238, and more, but it's a fun project to 
look at.  ;-)
