RE: [ slightly OT ] 1-wire hubs

[Frost Neil <Neil.Frost@xxxxxxx>]

I'm currently playing with the DS18S20 sensors daisy changed, to measure
the
temperature in each room, the software updates a text file for each room
and
a webpage picks up and interprets the data to give current temp, max
and
min. Still working on that though (If anyone can help with filtering
arrays
after being read from a text file using the filesystem object, feel free
to
contact me off list, alternatively I can supply some code).


Surely though, the whole point of 1 wire is it is just that so If you
wanted
a hub, you'd get some surface mount RJ45 sockets on a PCB/bread board,
connect the wires in series, have an output RJ45 socket, job done? Why
would
you need the extra bits if all you want to do is fancy daisy
chaining????

Just a thought, I don't know enough about electronics and stuff (who
said
they noticed.. ;) ) to know if I'm talking codswallop or not. Just
seemed
the simple way to me really.....

Hi

i) Yup, I'm interested in a build co-op, I am quite happy to get the
soldering 
iron out, but I'm not sure if any of the componets are surface mount.
If
there 
are, then I won't be happy.

ii) Yup I'm already using 1-wire sensors internally and externally to
monitor 
tempature, wind speed, rainfall etc. (temp only internally of course,
except

after curries :-0 )

at the moment everything is daisy chained hence the requirement for
hubs,
and 
also to save on bodge it yourself patching etc.

Andy

Are there any surface mount components if the Hubs/BP units?
