Over the past few days, I have been testing sensors, particularly ones to be used to log all info I will need from the plane. With some DS18B20s, a DHT11 and the Y-30 SD module, there will be a lot of data gathered.
The Arduino will log to a .csv formatted file on a 4gb SD card, which excel will open up easily, and allow creation of graphs. This is the first release, with some minor improvements in the future. Best to move on to the stabilisation side of things, being more important than a weather station.

Today finally got Earth Bridge to work, giving a live feed to Google earth. Earth Bridge is a little bit dodgy, but after debugging with full error messages on Google Earth I was able to get it to work for me using these settings with Google Earth 6:

The weather was cloudy, so had a dodgy gps fix as you can see in the screenshot it appears I went mining before a jump with my laptop out into the paddock. When the system works, it is a great way to display the data though.
Next step to put this through the xBee and have a live stream from the plane!
This is the output from having the temp datalogger set outside for a few hours.
Not a great change so close to a brick house, and under cover but still pretty cool and a good example of what you can do with the data from SD.
