Re: Tell me about 1-wire...

["simon_haslam" <simon_haslam@xxxxxxxxxxx>]

Thanks for posting those 1-Wire links & pics KevinT. I've found
the various wiring approaches for 1-wire to be quite confusing (DQ and GND
seem to be the only lines that are universally agreed!) and so the 1WRJ45
standard seems a sensible idea (why on earth Dallas/Maxim didn't come up
with it I don't know!).

I see the "1-wire headache" posts were from a couple of years
ago. Does Stuart (or anyone else) have any temperature PCBs they'd like to
sell (or any in the pipeline)? Also can someone suggest a good place to get
those double RJ45 PCB-mounted sockets (I tried Fleabay but wasn't sure
exactly what they were called)?
