Hiya!
I have a Raspberry Pi 4B set up as a print server, so it has to run 24/7. But it irks me that it’s mostly idling.
I’d move my website to it, but I don’t want to deal with it being open to the internet. The same goes for an e-mail server.
I was also thinking of running a Minecraft server on it. (Being able to play on the same world from different devices is kinda cool.) Alas, my RPi only has 4 GiBs of RAM. I worry that such a load would interfere with the print server.
Any ideas what I could run on it?
So I have a smart plug set up on my printer and print server (old HP 4P with separate network print server.
I have NodeRed watching my CUPS queues via HTTP scraping, and if it sees a job in the queue for that printer, it turns on the print server and printer via the smartplug over wifi. I have seen someone link a project that does something similiar.

Raspberry Pi I’m not sure if it’s worth it. But in short you can advance some science with spare CPU hours. Should be possible to limit it so it doesn’t heat up and use just a bit of the cycles depending on other load…
You could pihole
Some great light lightweight apps for a 4GB Pi:
- Homeassistant
- Fresh RSS
- Paperless NGX
- Syncthing
- PiHole or Adguard home
- Syncthing
I use my Pi 4B as a DVR for movies and OTA television (MythTV).
There are other tools that handle playback better (OSMC/Kodi, etc) but Myth’s configuration and handling of recording schedules is incredibly powerful. Conflict management works well and it can record multiple streams off the same tuner so conflicts are reduced in the first place.
Pihole, homeassistant, a music server using moodeaudio
Another vote for Pi-hole here. I don’t know how I lived without it before!
Does PiHole ever break a family member’s browsing, and then they don’t know to fix the issue because it would involve understanding opening up the PiHole web interface?
Yes, that does sometimes happen but the frequency depends on the blocking list used, or if multiple lists are used. When a family member encounters something like this, I can usually quite quickly identify the relevant blocked item and whitelist it.
And if you aren’t home or available?
I use an adblocker on both my PC and my phone. Does a Pi-hole have many advantages over that?
Running those adblockers on your devices is extremely insecure. They register as a VPN and intercept HTTPS traffic. They decrypt the encrypted traffic, filter it, and encrypt again meaning all your communications are signed by this single app’s certificate. Not to mention any vulnerability would wreak havoc.
I run AdGuard Home, WireGuard and a couple of other things on my 4B, all in Docker.
I used to run HomeAssistant on our for a while, but they stopped supporting that architecture (armhf?). Also used to run Unbound on it.
HomeAssistant is still supported on Pi4b
It’s support for the rpi3 that is getting fased out.
Another vote for a music server. Gonic/Navidrome is pretty low power and super useful!
Home assistant is another option, but I’ll say that if you’re serious about home automation you’ll quickly outgrow a Pi. It’ll run if you only have a handful of devices though.
I like the music server idea! Where do you get your music? Many artists don’t even sell CDs nowadays.
Home assistant is probably not for me. The house I live in is still very analogue. I enjoy not having to debug software when investigating why there’s no hot water.
Plenty of artists still do sell CDs though. I often buy them at the merch stand at shows. Many also sell DRM free digital files on sites like Bandcamp. I also buy a lot of music at the thrift stores and rip them. If all else fails, there’s always the high seas.
Almost every time I look on Bandcamp, the artist I am looking for isn’t there. :( Also, last time I tried buying something there they only accepted PayPal which I stopped using a while ago. But it seems they accept normal card payments now. Neat.
I buy CDs – I even bought a CD drive to rip them – but international shipping really kills me. I guess brick-and-mortar music shops are still a thing…
There’s also qobuz for your more mainstream music needs. And you can always use a YouTube downloaded like yt-dlp together with a music tagging tool like MusicBrainz Picard.
Its Qobuz 😅
You are right. I’ve corrected my comment
Maybe Nextcloud? Jellyfin?
I’ll add Jellyfin to the list! Do you need a specific client to receive a stream or can say VLC or mpv do it?
I wouldn’t recomend Jellyfin if it will transcode anything on a rpi4b.
