I designed and printed my own totally self-contained Stratux case, simply plug in the micro-USB power cord and go flying.
My design has a cooling fan and I printed it with ABS plastic so it should survive summertime use on the glare-shield. A couple strips of velcro will hold it in place.
The reception is great, I was receiving 10 978Mhz towers and over 6,000 1090es messages while cruising at 1,000" AGL.
See more details in my Reddit post at

Now I need to tinker with a j-pole antenna design to incorporate into the case.

Notice - the portable battery on top of the box is not good for built-in GPS reception - this was a test flight of ADS-B reception only. It will be plugged into a 2.5A cigarette adapter plug for normal use.
