Like a lot of fellow geeks, I have collected a few raspberry pi’s at home. For the longest time, these were basically bought and then were forgotten on a desk. At some point though, I finally got around to putting them to work for adblocking - and since then, they’ve become pretty much my goto machines when I need a server that’s available 24x7. Speaking to my friends, a lot are in the same quandry - got a pi, booted it up a few times and then it lies…. so here’s a list of my projects
- Current
-
-
Ad blocking with Pi-Hole
-
Wireguard VPN server - Secure Remote connectivity to home network when travelling.
-
SSL cert renewal for Gitlab pages - for static sites hosted on Gitlab with DNS01 challenge using CloudFlare’s API
-
Syncthing server - Secure, private file syncing across machines. Note that this isn’t the only syncthing server - there’s a couple of peers on the cloud - but those are throwaway.
-
Reminders server using
atdthat sends reminders over Telegram -Using hey.py -
CUPS Print Server for Lan wide wireless printing - The initial version was running on my router which runs FreshTomato
-
The router is way too slow to handle print duties, so I’ve moved it to a RPI.
-
IoT - MQTT server (Mosquitto), NRF bridge server etc 'Internet'-less IoT. Basically, smart lights and switches using Sonoff Tasmota where no data ever goes out of my router.
-
Minetest server with Redis backend - Minetest is an open source voxel game engine.
-
I’ll probably write this up separately - but for now I’m having way too much fun with cooperative multiplayer mode with the kids. Minetest default can be run on the pi (I’m using a Pi4 2GB) but it was being pegged once all of us joined in - likely due to the sqlite3 default backend. Redis being in-memory, offers excellent performance - the downside being that you do have to build it on your own from source.

Hosting comments for this site - currently this runs off a slow Azure server - but I might as well run it on a RPi

- Discarded

-
Single node kubernetes cluster using K3S - Even a Pi4 was a little iffy for this and I do have a decent desktop. So I’ve moved the K3s to my desktop - esp since I’m not using this for anything that needs to run 24x7
