Is that an airplane seat in a house?
One Pi Zero 2W runs NodeRed to control a few lights in the house. Another used to run Octoprint until it recently stopped responding. I haven’t gotten around to troubleshooting it yet.
It doesn’t lead to a destination, and maybe isn’t even a riddle, but a sentence I like is:
Is your answer to this question the same as if I had asked you to give me a dollar?
At least it’s something that could be added, as opposed to something that needs removing or changing. Of course, that doesn’t matter if there’s no desire or money to change it.
This isn’t a full answer to your question, but as for where secondhand keyboards are bought/sold, I bought one from eBay a while back.
Possibly the two newer Zelda games.
If I remember the name correctly, “Sleep With Me” is designed specifically for this purpose.
