Wireless GPS and environmental senders

[toqduj]

Any progress you could share?

Yup. the GPS and environmental sensors work robustly. When power is interrupted, the GPS module works another four hours on the 1.2 Ah battery, whereas the environmental sensors work for 3 days on the same (GPS is a power-hog). 

I am now working on 
  1) mounting the modules into decent housings 
  2) making an IMU module, and

3) I'm working together with another Berliner. We're going to demonstrate SK (and the modules) at the December mini maker faire.
