This project was born from a need to address a couple of features that I wanted to have in my truck.
The first feature was to have an electronic compass to serve as a companion to my 2 meter amateur radio rig. As a severe storm spotter, knowing what the direction is of the weather that I'm observing is essential for when I need to radio in my reports.
The second feature is more along the lines of creature comforts. Many vehicles these days have an outside temperature read out feature, however you very rarely find one that will display what the temperature is inside the vehicle. I always wanted to know what the actual temperature is in the car when I'm driving (and it's a great help in solving those age old debates that you sometimes have with your passengers on whether it's "too hot" or "too cold" )
