Despite appearances this project is not dead! I managed to assemble a complete board on about my fourth attempt!

This time I used a reflow oven and paste - I still had a few blobs to deal with but it was quite a bit easier!

Now I just have a lot of software to write and debug to get it working! It looks like the timing might be a bit off on the display driving code - some rows are brighter than others. I’m hoping this board might actually be powerful enough to use a timer rather than a loop which should make things more consistent.
