Dana, First up is getting logging of internal state. Then I get to setting up of GPS measurements.
Environmentally this is not as ideal location as one would want, but I will monitor the ambient temperature as soon as I have logging. I think I have a few other things to log eventually, so it will be interesting to see, but it is when these things is allowed to shift around one sees their effect. Exactly how I make things available is yet to be figured out, but I will keep you guys informed and updated at least.
