These are plans and thoughts on building a PC-based weather station.
First off all, let's describe the parts.

1/ PC
A PC acting as a server, mostly file and webb. It's always on and makes a good data collector, runs Ubuntu Server. In service.
20080209 - This one shall be replaced by a NSLU2.

2/ DS9490R USB--1-wire adapter.
This is connected to the server. In service.

3/ 1-wire network.
In this network we have some DS2405's that switch on electronic relay's that's connected to lamps an led's. We also have two DS2450 4-way A/D. In service.
