First I was thinking about a clock, and I've always wanted in a clock

I got to thinking, with my heating and air conditioning background,
that analog humistats operate off of voltage ramp principle so it
would be easily measurable. Barometric pressure would be reasonably
measurable, and the same with wind speed.
There are very tiny little modules which can provide the temperature and
humidity. they are simalar to waht are in the home weater staions..
for reference see:

You can look at the data sheets for ideas, I imagine there are also
other sources.
