TweetAWatt Python Scripts

    Modified script uses a text file to dynamically
    rename the appliance you are testing  here.

    Modified script that does the same as above,
    but logs the TOTAL KWH used in the
    spreadsheet, every five minutes here.

Natural Log Iterative Calculation
After writing some programs, we found the need to use the
natural logarithm function.  Unfortunately, the natural
logarithm function provided by Labview is not supported
when using NXT.  

    So we went ahead and developed this
    algorithm.  It works if the operator is greater than
    0 (x > 0).

    We left the source open, so feel free to poke
    around and adjust the iterations or the algorithm
    yourself!   

Thermometer Test Data
We ran some trials on the Dexter Industries Thermometers.
 You can see the results on our blog here.

You can download the data here:

Take our Survey!
This NXT-G block monitors the power available to the
NXT.  Originally designed for monitoring the power on a
dSolar System, it can also be used to monitor the battery
level of the NXT.  

Output is in mV.  Simple.  Elegant.
