I managed to get 4 complete working panels. Many of the small plastic holders for the dots have broken, they are amazingly delicate. I imagine that once installed and out of the weather they would have been reliable enough. As I mentioned previously every dot worked fine once it was mechanically whole again. I suppose with solenoids and diodes there's not much to go wrong.

Note to self: always set all dots to visible, so that they are horizontal. They are less likely to get damaged.

What a beautiful sight, 4 working panels.

An entire panel's worth of broken dots. Most are fixable if I find some glue that will work. But I could 3D print replacements I suppose.
