Nice!
For a moment there I thought you were perhaps the same chap who posted a similar thread some 2'ish years ago, but I see you've posted just 38 times, thus deduced that you ain't he. Although, you've prompted me to revisit another stab at a homemade Wx station.
Some time ago I cobbled together an anemometer, made with parts from B&Q, a CDROM motor and one of those bike computers from Halfords. It worked surprisingly well, until one particular stormy night when the anem' was last seen heading towards Pluto. In the end I dumped the bike computer idea in favour of a PIC. 'Twas then just a matter of stuffing the data from the guages/sensors into the PIC, then reading the results on a 2x16 LCD. The difficulty is trying to calibrate the anem' while driving along at a constant speed.
Keep up the good work.
