Not just patience - very good finger / hand control too! I'm glad she benefits from a nice set of magnifying glasses, as soldering the PJRC version of the Mini54 by hand is not something I would ever attempt due to the tight pitch and the fairly inaccessible pins on the bottom of the die.
Between two left thumbs, fat twitchy fingers, and only a $35 set of magnifiers, my results would be rather predictable, aka lots of magic smoke being released. So I stick to the biggest version of the Mini54 and whenever I make a board, I usuallu have to deal with bridging on that too, carefully removing some solder at a time.
So, hat off to Erin, kudos for the development of the LC, and I can't wait to see if the RTC on this one can be made accurate too!
