I use one running OpenWRT as a router. Its an old 3B, so it barely keeps up now that our internet has been updated to 100Mbps. It will soon be replaced, possibly with a pi 4. Of course, it also runs some other things. I have OpenVPN running on it as well as a little nginx instance that I can use for reverse proxying if need be. And the wifi turned out to be surprisingly solid as a (slow) access point, so I have somet…

Don't you need two Ethernet ports to use it as a router?

Are you using USB as the other Ethernet port?

One runs CUPS and is my printserver for an ancient but very reliable HP laserprinter.

One is our Internet radio in the kitchen.

One Pi 3 with a PiNoir infrared camera is used in a home-made camera trap for recording the local wildlife.

Two Pi Zero Ws are used in my son's high altitude balloon cosmic ray high school experiment, recording video, and reporting GPS altitude and Muon count rates via 50bits/sec RTTY.

One is used in a beetbox I built for a BBC TV show. Not this one, but pretty similar: https://newatlas.com/beetbox-vegetables-musical-instrument/2...

Then there's assorted robots, but none of those are currently operational.

I have several running 3d printers-- OctoPi or NanoDLP. I've been able to modify OctoPi to run several printers at once, but it is way more work than its worth.

I also made a media player for my daughter that has all of her kids shows on it. I designed/printed a case for the RPI+vesa mount. I'm super excited about the new RPI that was announced todayish-- because it has a hardware h.265 decoder meaning, I'll no longer have to transcode some things.

I tried PiHole and I really liked it, but it caused some problems with some sites my folks frequent, and it broke mDNS discovery on my network. I may reinstall it and just exempt their devices.

I run a grid of about 250 Pi 2 and 3s across several offices and datacenters. They are the backbone of our graphics playback system (i.e. slates) and low latent IPTV system. Users can subscribe to any channel necessary without expensive re-encoding or RF antenna systems. I absolutely love them and 4k60 HEVC is a huge upgrade for the 4!

Wouldn't it be less expensive and simpler to buy a few real servers ?

Hi!

If you are interested in a 100% offline and private-by-design Voice AI, you should take a look at what we are building at https://snips.ai, it is 100% free for Makers

This allows you to do a 100% private Home Assistant, or add voice control to any of your projects :)

It works for english, french, german, japanese, spanish, italian, and more coming, and runs on a Raspberry Pi 3 (and iOS, Android, Linux)

You can take a look at our blog to see how to get started https://blog.snips.ai

We would love to publish on it what you are building with it!

I used mine as a NAS for a while with an external USB HDD and a samba share. It was also set up to be a VPN and pi-hole. I have a pi zero that I use to flash coreboot on laptops. My PS3 isn't doing so hot as a media server client for my NAS's movie library - the network connection is poor, the interface is fiddly, and it can't load subtitles embedded in files. I was going to buy a pi3 to replace it as a media server…

Check out ROckPro64, I just set mine up. Running plex with an internal HDD on a PCIex4, 6 core processor and 4gb ram. Using Dietpi, I am interested in checking out the Pi 4 as well, but looks like it might be a few months until its available

I think I have at least one of every variant. I had fun playing with all of them. But in the end, I wanted to use one for a Linux development machine and it was always just a bit too slow to be useful. This one sounds like it might have just crossed into the lower realm for laptops so I'll give it a try. And yes, I know, using it as a development machine was not really the intended purpose, but a $55 machine is so tantalizing.

Using several Raspberry Pis to monitor CO2 levels in my house. Each Raspberry Pi has a CO2 sensor - wrote a little Python script to retrieve data from sensor and upload it to a server Which is also a Raspberry Pi.

I like this! I'm already using Pi Zero's like this for temperature sensing; adding a CO2 sensor sounds like a good enhancement!
