What's your use of Raspberry Pi?

The Raspberry Pi is a series of very affordable credit card-sized single-board computers developed in the United Kingdom.

As it is described in this awesome GitHub repo, the sky is the limit when it comes to the projects and the use cases of it, it all basically boils down to your creativity and needs.

As of June 2020, the most advanced version is Raspberry Pi 4 Model B, offering up to 8GB of RAM, USB-3 ports, Dual Micro HDMI ports (supporting 2k and 4k displays) and other superior features.

Do you already own some? What is/would be your use of Raspberry Pi?

I run Scrapy on mine for web scraping!

I have one Raspberry Pi 3B+ and I bought it to try this platform. As a result, rpi worked for about a year in the office as a music stream server. I installed Raspbian with DE and periodically connected via VNC for playlist switching.

Then for a while I used the rpi as a bluetooth adapter in my car. I installed balena-sound and connected the power supply from the vehicle's on-board. Yes, it is overkill - running docker-containers inside full-featured computer only for converting bluetooth to aux =)
I later replaced it with hardware bluetooth->aux adapter for 5$.

Currently my RPI is idle.

I have a few Pis around my home office.

• The first is an original model B: an ISS tracker, complete with LEDs that light up when it's overhead.
• Another original model B is a private git server, for code repos that I don't want hosted anywhere else, and as a backup for my public repos.
• I've got a model 3B that I've turned into an arcade console, complete with custom joystick case. I went this route rather than building a cabinet so that I can plug it in to my 43-inch 4K TV.
• Another model 3B is a Cardboard version of a Google Home box.
• I'm in the middle of setting up a model 3A to act as a NAS server to host my 8TB external drive.
• I plan on turning a Zero W into an animated name tag, with the addition of a three-color ePaper display and USB power bank.
• My 4B-4GB card is set up as a desktop environment for simple code development. It will probably also control my 3D printer.

Finally, I have a few Zero W boards that I give away at hackathons. I think I'll turn one of them into a PiHole.

• 4x Raspberry pi cluster that I use to teat out apps that I write so I don’t accidentally get a huge cloud provider bill.

• Media client for my tv to stream some downloaded movies.

• Pi-hole , I use this as a ad block for the tv / phones and dns filter to block some requests.

• I got one hooked up to my amp so I can play some music through it without connecting my phone directly to the amp when I have a parties.

Ons thing that I still wanna do is setup a nas server with one so I don’t have to copy files between devices and I can access my files from any device.

I created the following projects for development and testing:
-Four-node Kubernetes cluster computing with 3 Raspberry Pi 4 4GB controlled by Raspberry Pi 4 8GB running K3s on RaspberryPiOS
-Five-node Docker Swarm cluster computing with 4 Raspberry Pi Zeros and a ClusterHAT controlled by Raspberry Pi 3B+ running Docker Swarm on RaspberryPiOS

Using a 3b + with a Pi Hat and two 1TB external HD for a Nextcloud install.

Pi1A: "traffic light" telling a 3yr old when it's time to get up and when to stay put in her bed.
Pi2B: bread proofer. Basically a thermometer and lightbulb to control temperature in a box to let sourdough rise consistently. Accessible via ssh over the Internet.
Pi3B: home server.

• Pi 4 with 8 GB ram: as secondary desktop running Ubuntu 20.04 classic (GNOME) for arm development.
• Pi 3: TV box for netflix, running LibreELEC+KODI.

I use my Raspberry Pi to host my Discord bot 24/7. The bot serves memes and pulls Onion news articles for my work colleagues.
