Asking for lists, or other open-ended questions are usually discouraged in most SE sites, including this one.
In space exploration stackexchange (SX-SE) I've just asked the question What would be the (most difficult) challenges to making a "10,000 year satellite"?.
Just briefly, it's a question about a at-least-partially mechanical satellite that - like the 10,000 year clock - should be designed and launched into an orbit such that it's reasonable to expect or hope that it lasts for 10,000 years. Once a year it should emit some rudimentary radio beep, flash of artificial light, or at least change its reflectivity to suddenly "appear" for a few weeks.
Now, I'd like to ask here in SF SE if there have been stories with descriptions of some kind of mechanical satellite - something that has been designed to make use of low tech mechanical or other things so that it might survive a long time and then "wake up" and do something.
The first, burried obelisk in 2001 A Space Odyssey might be an example of something that wakes up an does something, but they were (I assume) not low-tech mechanical devices.
But I think I'm getting close to being off-topic. Any advice how I might be able to proceed?
