The second "minimal build" attempt is blinking it's onboard LED (powered and programmed via ISP connector.) (pictures posted)!!  Working on the "variant" file...

The first attempt seems to have power and ground shorted, demonstrating that my SMT soldering skills are lacking, even with the 0.8mm LQFP that I was hoping would be relatively "easy."  Sigh.  I seem to have trouble getting the pins to line up on all 4 sides at once (at least with either pin-at-a-time or drag soldering using an iron.)
I guess it's time to break out the hot-air system I bought a while ago.   But I need younger eyes and two right hands...

About the "eyes"... I can only recommend to use an Amscope SE400 (https://www.amazon.com/AmScope-SE400-Y-Professional-Microscope-Magnification/dp/B005C77FPY/ref=sr_1_3?ie=UTF8&qid=1521025585&sr=8-3&keywords=amscope+se400). It's one of the best tools I've ever bought...
