I got a RPi 3B as my Pi-Hole that I'll eventually use as my Wireguard VPN, too. Hoping to get another Pi device for hosting Jellyfin on.

I bought a pi0 when I first started hosting things. It ran a pihole and piVPN instance for about 3-4 years before it died.

I would love to have another one, they are great pieces of hardware.. but are just scalped to hell. I'll keep buying old desktops and laptops with higher specs for cheaper until the costs go down.

I have one 3B running adguard and a wireguard vpn server. Another 4B doing the same, plus kitchenowl and home assistant.

Only use it as a backup pihole now. Used to have an *arr stack on it, but needed a beefier pc

Testing ideas with kubernetes before moving to the POC stage

I have a 4 meg Pi 4b running Pi-hole and Mini-DLNA. It’s rather under-utilized for those tasks, but it serves them quite well.

Yes.

The jobs they do:

LAN print server

Running OctoPi for a 3D printer

PiHole and VPN for the home LAN

Experimenting with OpenHab

Portable Kodi box.

And a crappy mass storage server via USB.

1 Pi 4 for two things

1. Download media over a persistent VPN that auto-moves to my NAS
2. Fun play toy as a dev box to test new tech and try to stay current and keep my Linux skills sharp since I use osx at work

1 ends up blocking 2

I really want to buy like 5 or 6 with temp sensors to put around the house to see how good my heating/ac are working, and confirm wifi strength

One Pi Zero 2W runs NodeRed to control a few lights in the house. Another used to run Octoprint until it recently stopped responding. I haven't gotten around to troubleshooting it yet.

Pi 3b to run syncthing

ADS-B antenna that feeds Flightaware, FlightRadar24, and ADSBexchange

I have one set up as an irrigation controller. I was going to build an OpenStack cluster to test configuration settings on (I run a production cluster at work), but gave up when the supply chain problems happened and prices skyrocketed.

I used to have a self-built, locally-hosted power strip with individual outlet control that served it's own interface. It was powered by a Model B+. I've since moved to home-assistant and zigbee plugs since my self-built solution was pretty bulky, but it was by far my longest lived Pi project.

I use my pi for 3dprinting management.

Mostly as kodi/plex front ends. I've set them up as a kubernetes cluster in the past but they didn't have enough ram to run my torrent client. Now I just use an old Thinkpad running talos.

I have a Pi 3 running Home Assistant. I also have two Pi Zeros that I have MP4 Museum installed.

I use MP4 Museum to run projected Halloween decorations mostly but it's great to have a little box that will take a video file from a thumbdrive and dump it out the HDMI port on boot.

I have a Pi4 that is running Homebridge and pihole.

I have a water container I need to take care of in my house. An ultrasonic sensor hooked to my raspberry 3b uploads the collected data to my vps that later serves an html through Flask to show the water level. It has a few alarms so that I can take action at the appropriate time. The ultrasonic sensors HC-SR04 suck and I have to replace them quite frequently. Other then that it works really well.
