D&D General examples of high tech stuff in dungeons and dragons?

Whether it is stuff involving Castle Blackmoor, or the most updated module, where have they used high-tech stuff?

I think I want to do my kwalish concept for dnd and want to figure out what to draw on.

There was that whole module with exploring a spaceship that crashed in the High Forest of FR. Barrier Peaks- The cover even has a guy with a ray gun.

Anything Spelljammer.

Most magic items such as magic stones that let you walkie-talkie with each other.
