Windmill Notes: How to Set Up Data Logging from Your 

We designed Windmill Software to be versatile enough to 
log data from many types of measurement instruments. This 
versatility, though, means that there are several set-up 
options that you may not need for your particular device. 
To help you choose the settings to use with your instrument, 
we have examples for a wide range of instruments from 
balances to oxygen meters. 

Among instruments covered are: A & D Balances, Adam PGW 
Balances, Datel Datatakers, Garmin GPS Receivers, Mettler 
Toledo Balances, Ohaus Pioneer Balances, Quadra-Chek 2000s,  
Sartorius Balances, Sylvac Dial Gauges, Turner Fluorometers 
and YSI Oxygen Meters. See the full list and get your 
settings at

We need your help to expand this list. If you would be 
willing to share your settings to save time for someone 
else, please get in touch: e-mail [email protected] 
All we would need are 
- your *.imd file from your windmill setups directory 
- the iml.ini file from the 
  c:\program files\windmill software\windmill\ directory
- the make and model of your instrument
It would also be useful to have an example of the data 
string which your instrument sends.

Excel Corner: Overlaying Google Earth with Excel Data

"Do you know of a way to take Excel data and overlay it 
onto a Google Earth Image?" asked one of our readers.  

One way to do this is to create a "KML" file from your 
Excel data. 

KML is a file format used to display geographic data in 
applications such as Google Earth or Google Maps. It is 
a text file based on the XML standard.

Before you can convert your Excel file to KML, you have 
to arrange your worksheet in a specific way. It should 
contain at least 3 columns: latitude, longitude and your 
data - for example depth. Change the title of the 
data column to Name.

There are several utilities out there that will convert 
your file for you. I like Earth Point's offering at 
Some others are listed below. To use the Earth Point tool:
- Look for the Choose File button on their web page, 
  and browse to your Excel file.
- Click "View on Google Earth". The Earth Point utility 
  will save your file as a KML file.
- Open Google Earth on your PC.
- From Google Earth File menu, open the file you have 
  just saved. Your data will be overlaid as labelled points.

Adding More Information
You can add other columns to your spreadsheet, providing 
more details. For example, if you add a column titled "Description", 
whatever you type here will appear in Google Earth as a 
pop-up balloon.

You can also show a moving track of data over time: more 
on this in our next issue.

Getting Data into Excel
The above is all very well, but how to get the data into 
Excel in the first place. With Windmill there are two ways 
to do this.

1. You can use Windmill Logger to collect data from a 
   GPS receiver and measurement device, and then open the 
   saved file in Excel. 
2. You can send the data directly to Excel.

Robotic jellyfish fuelled by hydrogen 
   US engineers have invented a hydrogen-powered robot 
   that moves through water like a jellyfish. Robojelly 
   could eventually be used in underwater rescue operations. 
   Being fuelled by hydrogen means, in theory, it will 
   not run out of energy

Industrial networking market to grow
   The market for industrial networking is still strong 
   according to a new report from IMS Research.  An 
   estimated 31 million new fieldbus and Ethernet nodes 
   were installed worldwide in 2011; this number is forecast 
   to grow by an average of 10% a year, to just over 
   45 million new connected nodes in 2015.
