Thermistor into XP computer excel

[rob]

I am recording 7 locations for temperatrure with thermistors and a
digital Multimeter and manually entering into an Excel spreadsheet. I
would like to automate. I only need to take sample temps once every
15 minutes (or so) 12 hours a day.

i saw a site where 2 temps can easily be logged into excel via game
port, using Visual Basic in XP.....soooo....I figure it shoouldn't be
a big stretch to do what I want.

Can anyone point me in right direction to build hardware to do
this?..or if more than moderatly difficult an off the shelf card...I
am aware of Data logging hardware out there but again I would like to
try to rig myself.

Thanks in advance...
Rob

A PC running XP and visual C should be able to handle that data rate. If
your PC has a serial port, chances are the easiest way to get the numbers
in is via RS232. There are several companies that make ananlog to RS232
converter boxes. Perhaps one of those would serve your needs.
