Low-Budget Home Weather Stations?
Toby Truman asks: "Working at the Fenwick Island Weather Station, I already have access to million-dollar meteorology equipment. However, some tinkerlusting college friends have been asking me about home weather stations, a subject I don't have a lot of experience with. Have any Slashdot users experimented with DIY weather stations, and if so, what do they recommend?"
See wunderground's page on personal weather stations here .
Brian C Lane has Linux software available for measuring temperatures. It uses the Dallas Semiconductor 1-wire thermometer and includes directions for building & connecting it to the serial port. You can find it here.

The weather stamp is a project kit based on the Basic Stamp microcontroller. If you're not familiar with the Basic Stamps, they're easy to program and very versatile. The weather station is good for a few measurements and only costs between $30 and $50.

I recently hacked a temperature sensor out of an old <a href="http://www.atarimagazines.com/v7n6/gravis.j<nobr>p<wbr></wbr></nobr> g">Gravis joystick</a> and a broken diode. I had to calibrate it "by hand" (in the code to read from the joystick port), of course, but it seems to be accurate to within a degree (F) or so. So for the cost of one diode (on the order of one cent?) and one ancient joystick (free from a friend), I got myself a handy little temperature sensor. Oh, and with <a href="http://people.ee.ethz.ch/~oetiker/webtools/<nobr>r<wbr></wbr></nobr> rdtool/">rrdtool</a>, I get nifty graphs, too!
