I attempted to build the Google AIY Vision Kit .
I got to step 25 and when I was closing the cable connector for the vision bonnet the latch broke off the Pi Zero board, so now it is basically broken and the kit is useless.
The assembly of the kit is much more complicated than I anticipated. I can't imagine a teenager being able to do the assembly.
I now have a partial kit and a broken Pi Zero board that I need to decide what to do with.
