Ask HN: What are you doing with your Raspberry?

I've had a Raspberry Pi gathering dust for a long time, and I would like to do something with it, preferably involving an e-paper display, but I can't find an interesting project. They always seem to be the same. I would love some creative ideas.

Also, welcome are educational ideas for girls (I have two).

Running a backup instance of pihole. I have my primary instance on my "server" and run a secondary instance on the pi so I can point my DNS at two separate devices so downtime on one doesn't drop my internet.

like many people. the majority of my collection is sitting in a drawer somewhere. pihole is a honourable mention and use case if you are looking to put them to use.

Wireguard that 1) connects multiple houses across the world into one transparent network with each node serving a local DNS with Adguard for 64-bit or Pinhole on 32-bit-only ones; 2) provides private passthrough VPN that turns on automatically whenever I'm not on a home network.

It's a RPi 3 A+ and it is sitting in my drawer. I plan to install a game emulator later. Unfortunately it only has one USB port so I also need to buy a USB hub.
