Hi,

Don't forget, a meter can be set next to a clock and they can be watched 
with a camcorder.  If you already have the stuff, that costs zero.  If you 
have a video capture card or one of those webcam things (cheap now too), 
you can find free software out there to grab and store the image say every 
15 seconds.  Might not impress NASA, but it sure is cheap, easy, and just 
as effective!

Cheers,

         Terry
