Working.
So now I have 3 working 1-wire temp sensors, two of them at the end of 30+ meter cable runs.

See

The wavy bit on the green line is the air conditioner oscillating between the set points. The red line is the temperature of the cupboard that houses the file server.

So now I just need to finish adding the other sensors, and start connecting the results to the air-con dampers...

Awesome - and more than a bit helpful!!

I'm planning on monitoring the batteries on my wind turbine using a pinch of DS2438 chips (12 6 volt batteries in the bank) and have been stalled looking for a way to get the 1-wire in and out of the ngw100 board.

You can check my progress on the wind turbine here.

The LaCrosse weather station I'm using works a treat with the Cacti php interface to rrdtools and provides
some pretty useful graphs. Might be a good addition to your growing arsenal of tools in your own toolbox :-)

Let me know if you'd like the eagle cad files.

This board is working well and reliably. Very happy with it. The only minor thing I'd change is possibly using screw-terminals instead of RJ45 sockets. This would make the board slightly bigger (about 20%) but make it a little more flexible for hookups.

I'll post an updated version of the source code tonight (It's slightly more robust in 1-wire searches).

That turbine looks amazing! What are you using to measure air pressure?
