2 Pis for dealing with ADS-B (airplane data), one for 1090Mhz, the other for 978Mhz. I could run that on the same one, but seemed easier to just split them up given some of the software is a bit picky with device IDs. The 978Mhz is much quieter than the 1090Mhz, so I also run a private SpyServer (https://github.com/lloydpick/docker-spyserver) for listening to radio transmissions.

1 Raspberry Pi for a running a very stupid sitcom sound thing. Using a camera it tries to recognise who you are, then play a random sound assigned to you out of a little speaker. Think of like the cheering/clapping when a guest or celebrity enters the room in a sitcom tv show, and replace out the clapping with whatever sound you want.

A Pi for UniFi, a Pi as a print server (older model) for a USB laser printer, a Pi as a print and input server for a thermal receipt printer that only has serial (or a 350$ option for a 10Mbit ethernet addon) + a button to fetch a hotspot code from UniFi and print it for a guest for limited guest access. And a free floating Pi for various functions, sometimes as an I2C board, SPI interface, Scan server, placeholder when one of the others is in maintenance etc.

1x Raspberry Pi 3 installed in my car within the internal network as a bastion box and to run software that let's my interact with the entertainment system 1x Raspberry Pi 3 running Home Assistant with a Z-Wave USB Dongle (Home Automation) 1x Raspberry Pi 3 running OctoPrint (Host/remote-control for 3D Printer) 1x Raspberry Pi 3 running FullPageOS (Full-screen Chromium in kiosk mode) displaying a server statusboard i…

FYI - I had to buy a Pi 3B+ to run Unifi Controller, the forum posts said the Zero W didn't have enough juice.

Seconding this... it'll just barely run on the Zero W, but you need 64-bit Java to remotely access your controller through unifi.ubnt.com, and there'll be long delays whenever the database needs any maintenance.

(I set up a Zero with the Unifi Controller -- connecting to the LAN using a Chromecast Ethernet Adaptor -- about a year ago, and had this problem, so I switched to a 3B, and all is well now.)

I will use my first one to power a hard drive that I leave with family or friends. They'll have a small box (mind the inclusion of an external hard drive, still a relatively small box) with my off site back up, and I could host the same for them. This is after a failed plan to use it for Android TV (my girlfriend made the mistake of picking a WebOS TV and I made the mistake of thinking it wouldn't be so bad). The old…

Regarding your mutual backup idea, I love this and I've wondered why this hasn't taken off as a Thing in response to how many of us are untrusting and DIYers in this era of cheap storage and bandwidth.

Indeed! I'm not sure why I don't already have three hard drives from friends, it's 10x cheaper than S3 or Backblaze B2 or any such thing. I've had this idea for years, but seeing that someone else built exactly this[1] while also having time for it soon gave the idea another push.

It used to run kplex to bridge NMEA data (wind speed, depth soundings, boat speed, etc.) from our SeaTalk network to TCP/IP. Now a GL-AR300M does the job though, along with all the Wifi/GSM routing, saving one computer and power (when running strictly off solar and batteries, this matters).

Have you by any chance documented how you did this, or could you link me to where you learned how to set this up? This is actually one of the projects I puttered on for a long time with one of my RPis (NMEA-2000 to SignalK) but abandoned because I had too many moving parts.

In the process of moving our Hardware Test infrastructure(Think Selenium for testing hardware)over from Windows SBC based solutions to a R-Pi-Zero based solutions. Applications range from driving stepper motors, sensors and generating pass/fail results. The inital investment is in porting all the code written for Windows to embedded linux but the investment pays off in the long run in cost minimized by moving away from a Windows desktop. Will do a write up of how i achieved it once i have some concrete results.

I use it to run my automated watering system in my garden. https://github.com/davidbanham/relay_runner I used to use an esp8266 but replaced it with a Pi after a lightning strike destroyed it. The Pi is just so much easier to write software for and it's been no less reliable in practice.

Why would it be less reliable in theory? The obvious argument against is that it's 'expensive' [relative to what you need], not, I wouldn't have thought, that it's unreliable.
