Khurt, I understand the D40 side of things - I think I just misunderstood some of your original post.. I've read it back now and get what you are doing...

One new question, when you go out in the field do you have the RaspberryPi turned on (plugged into your power source) constantly?

I guess it doesn't consume much power?

In addition Is setting up the cron job straightforward?

Thanks!
