weather station mods

[Snidely]

Hi!

New to the group, but a quick google didn't turn up anything
appropriate.

I'm looking for info about mods to cheap weather station devices to
allow hooking them up to a computer for data logging purposes.

Mid-range instruments often have an optional adapter, but paying $200
for an RS232 interface seems rather -- taken.

I'm wondering if anyone around here has experience with taking data
from $30 -50 instrument (Oregon Scientific has a few in this range,
and the now-cleareanced Target "Eddie Bauer" weather monitor was
less). These don't have wind speed gear, but that's available cheaper
than RS232 adapters =8-0.

Thanks!

One of the routes I'm imagining would be to do take-offs from the
display module leads, with a Stamp to translate these back to data
values, but it wouldn't surprise me if some of these units had a
serial port at TTL (or other logic) levels, only needing a level-
shifter for RS232 hookup. Or maybe USB in the newer ones ;-}
