There appears to be 8 reed switches, and two rotating magnets arranged adjacently. Perhaps one is not a magnet, and just a counter weight.
I marked one of these magnets and then rotated the vane shaft 45% and took a reading, and repeated until the marked magnet was back to the original position. (previous table) I've just checked though and there are other valuse combinations, and also a second set of four volt values. So perhaps there are more than eight recordable positions. volt.ALL 0.0658604, 0.0600009, 4.55241, 4.5428 volt.A 0.0644541 volt.B 0.0661729 volt.C 4.54171 volt.D 4.54741 volt2.ALL 0.0352349, 0.0302348, 0, 0 volt2.A 0.0351568 volt2.B 0.0298442 volt2.C 0 volt2.D 0 More research needed... -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Alfille, Paul H.,M.D. Sent: Saturday, 4 June 2005 2:50 AM To: [email protected] Subject: RE: [Owfs-developers] 1wire weather station v3 Vey interesting. I'm surprised directions 5-8 don't have two channels with non-saturated values. (A between position.)

Mysql would be my db of choice, but the interpolation features of RRD look intriguing. I think I may use this project as an opportunity to play with python, I hear nothing but praise for this language. ------------------------------------------------------- This SF.Net email is sponsored by Yahoo.
