The Pressurized Payloads Interface Requirements doc is kind of interesting. Lots of diagrams & such that would be great for art projects.

That was an excellent read for explaining why space isn’t just hard, but expensive.

The flow diagram provided for fracture control is incredible. Quite a work of art. [1]

Update: After staring at this flow diagram for quite some time, I realize it's actually the most robust, "complete-seeming" finite state machine I have seen used in the real world.

Good read.

"Since that time, I’ve learned that small heaters (like coffee makers or kettles) can be kryptonite to an inverter, and that this is common folk knowledge among solar installers."

Is there any more on this? It can understand inductive loads maybe challenging inverters but resistive loads should be easy? Is it an issue of cheap inverter design, or something more fundamental?
