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?
I run a asterisk PJSIP VOIP server on my raspberry pi 5 8GB. I had to use the git and build and recompile and manually load all PJSIP modules because for some reason I couldn’t even find an asterisk package on apt db for ARM64 for some fucking reason. Also had to containerize it within a docker because the shit couldn’t properly compile without interfering with native system binaries. Shit is so fucking goated and can do PSTN via twilio trunking (call numbers outside of the phone server’s number base so basically anyone as long as you make the phone numbers parsed in extensions.conf for each country you wanna call XD). Currently works within LAN but I am planning on making it accessible over the internet using my domain and a tunnel for UDP if possible or just a VPN since my router is being a removed with SIP packets rn. I am having trouble with that part but once it’s done I can quite literally ditch any phone plan and use it. Twilio hardly even charges shit for voice rates 🤣🤣🤣. You could also self host your domain + email providing service and then connect that to thunderbird for full schizo-level privacy or sum shit. That’s what I do to ditch web-email BS
PiHole is a pretty light load, as are Home Assistant and Music Assistant. Frigate starts to make some heat, so don’t expect to get a full blown video classification / recording system.
BirdNet Pi!
Some great light lightweight apps for a 4GB Pi:
- Homeassistant
- Fresh RSS
- Paperless NGX
- Syncthing
- PiHole or Adguard home
- Syncthing

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.
let it run dwarf fortress from within the terminal, then ssh into it from wherever you are so you can play df from anywhere in the world. i did this at work.

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…
AdGuard Home (I prefer it to PiHole)
OtterWiki
Wireguard

Can I please ask why you prefer Adguard over Pihole?
The sd card in my raspberry 3b recently died, and my pihole with it. I am now using Adguard but not sure it’s working well for me, consider going back. What’s the winning argument for you?
I find the interface feels more modern and interactive, I didn’t like how static PiHole felt with adding to a list then manually restarting Gravity.
AGH has support for more list types, it has more features built-in, such as DNS over TLS so I can use it on my phone even when I’m not home.
And personally I feel like its less buggy, I’ve never encountered a problem on AGH, whereas I did on PiHole.
Interesting points, thank you.
Today I wanted to block everything with facebook and Instagram, it looks like I am hand-editing a config file to do so. And it applies to the entire network; AGH has no concept of user groups. Am I missing something really obvious?
That would be something you do within the Client Settings page. You can have custom settings that are separate from the Global Default.
You could pihole
Airsonic music server… There are a few quirks getting it all set up properly, but once it works, it just seems to work forever. Samba file sharing server. Also miniDLNA server can make it easy to watch your movie collection on a tv. The airsonic DLNA doesn’t seem to be working currently. I also have a few mastodon bots running from a Pi4. Also could run a tor relay node, which would make it so it’s less idle. I have a lot of stuff on my Pi4 and it is still mostly idle most of the time. Thats fine though. For me it’s not a huge problem, since overall, my goal is to make it use as little power as possible for all those things. I think thats the whole point is to really use the most lightweight computer that can do what you need. If you just need the print server, you could always get a lower power Pi so you can really optimize how much power needs to be used and maybe even do some sort of Wake on LAN setup so it can be sleeping while not in use.
Jellyfin music server. It needs about 1.2 GB of RAM for itself, plus the system.
My PI with podman jellyfin and flatnotes is sitting at 600 MB ram
Mine needs 1.3 GB with an itunes library of 160 gb.
Ah yes my collection is less than few GB that play I guess
You can run an (emulated) IBM mainframe on it!
mine is my reverse proxy, using the nginx proxy manager docker install method
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.
