You could build a anemometer form ping-pong balls and attach a megnet to the axis. You can then read the revolutions without contact by a hall effect sensor. I think those those sensors have integrated opamp so they output could be feed directly to ds2423 counter. I for time measurement you can use DS1904. It's an iButton RTS with it's own power. You can change your system to a wireless router with USB(for cameras) and if it wakes up you read time form iButton. Owfs runs very good on OpenWrt. If you know how strong the winds is You could consider if it's worth adding some small wind turbine. -- p4trykx ------------------------------------------------------------------------------ Get your Android app more play: Bring it to the BlackBerry PlayBook in minutes.
