Maybe electrical outlet testers. Things that could improve safety but are largely left sitting unused 99% of the time.

This could have security implications. I believe most libraries have a computer to use, not sure on permissions of using a usb stick.
Edit: I'm from US, so I am assuming Canadian libraries typically have a computer for public use.
Definitely look up a how to. It's been 15 years since I did this, but you'll need some photo paper to print the toner on, then use a towel and iron to transfer it to the copper clad cob. Then soak it in some FeCl for 15ish minutes. I just did this outside since it was so quick. Then like a small dremel with pcb sized bits works great for throughholes.
lol I remember installing and running this, and just thought, wow, this wasn't worth it. Now, 30 years later the use was made clear by you and I should've thought about it when I first went multimonitor. Thank you!!
