I am starting to go stir crazy the last few days, since June 26th, 2015 when I sent my P3P off to be repaired. I decided to create portable metal free imu calibration solution for outdoors. It's nylon bolts / nuts, plastic platform, a non metallic bubble level, and a tad of glue to hold it all together. Made to fit in both my Seahorse case as well as my soft shell backpack. Now all I need is my drone back from Calif.
