The hub components and board arrived and it was the hardest soldering job I've done yet. No obvious flaws, though I wouldn't say that I was proud of every joint. Most testing went well, but a small part but important part doesn't quite work. 

My oven that is destined to be a reflow oven is being borrowed for my brother in law's school project. Eventually I want to try reflow soldering this board to see if that fixes some bad joint.

In the next few days I may try some more debugging of the board, but I expect I will take a detour to more mechanics or aesthetics until I have the reflow oven working. 

I will gather my thoughts and make another post soon.
