I use Raspberry Pi for crafting simple appliances such as:
WiFi Router + Switches, I do not use any ready-made opensource router firmware, I simply configure the whole Linux Debian with added packages such asipfilter,dnsmasq, etc. That's the simple network firmware I did.Torrent TV Box, build with NodeJS, I manage the downloads via a web-based interface from any devices connected to the same network, some times over the Terminal.Power Management, It's for controlling and monitoring my home power consumption, I can set which appliances have exceeded the threshold limit and turn it off remotely, I use external advanced PLC module to managing it more effectively.Rogue-Calibre, this creation is to prevent too much high-frequency WiFi active at midnight while I sleep. It paralyzed the WiFi routers surrounding my house within the radius I set.Raspberry Piis for entry-level, I would like to see a post that discussing other advanced FPGA or SoC such asParallella,Arty,NVIDIA Jetson, etc. I have a different story for them.Could you share some details about
Power Management? ThxPi 4B 2GB: main desktop running Ubuntu MATE 20.04, hooked onto a VGA monitor via VGA666 adapter.
Light web browsing in Firefox, light code editing in Pluma (compiling on remote machines), participation in Google Code Jam and similar (compiling locally if I use Python or C, otherwise remote).
Pi 3B: previous desktop, now inactive.
Pi Zero W with camera: home surveillance.
I never got it working fully: no motion detection or recording, but I can connect to it and watch.
I made a slick GPU accelerated contour detection though yoursunny.com/t/2018/contour-PiCam...
Pi Zero W with small touchscreen: inactive.
Have you often run into RAM limits (w/ 2GB vers), or is it enough for your use? 👀
2GB is enough for 3 browser tabs (Slack or Facebook or Gmail can open one at a time; other two are simpler pages like Python docs) and 10 files open in Pluma. VS Code struggles so I stopped using it on this desktop.
I have 2GB swap partition, using a spinning drive taken from a 2005 laptop.
Both 3B and 4B-2GB were hackathon prizes. If I'm to choose, I'll want the 4GB. 8GB would be overkill in comparison to this CPU.
I have Raspberry Pi 2 which I use as a ad blocker using Pihole and as a wireless print server for my old USB printer
That's exactly what I do with my Pi Zero W as well :D
Hahah 😃😃 Yeah, as I said, you can find the use case for it for virtually anything 😃😃
I'm working on a Raspberry Pi Zero with an amp HAT to take a pair of old speakers and converting them to smart speakers. First, just make them available as a Spotify device, and maybe later I'll build a multiroom setup.
Are you going to use the balenaSound setup? I have one on our pool deck and one in the garage. Not as slick as sonos but way cheaper!! 😊

I'm actually planning on using raspotify which seems like the simplest approach. :) It doesn't allow me to Cast to it with the Chromecast protocol, but that's next step ;)
Have you heard Raspotify before?
github.com/dtcooper/raspotify
Yes! That is actually what I'm planning on using actually. :)
I have seven Raspberry Pi 3s running as part of a Kubernetes cluster with an eighth one being used as a gateway/router that connects to my network and exposes the connection to the others.
It's kind of difficult to find ARM-based Docker images for a lot of popular software to run on it and the Raspberry Pi 3s only have 1gb of RAM so they don't have much to spare. It was a good learning experience, though!
I have a few 4gb Raspberry Pi 4s with Power-over-Ethernet (PoE) HATs that would allow me to make a really clean looking and more powerful cluster... but I haven't found the time to do so. 😅
Nice one 👍😉
I wrote a Python script to log some stuff to a Discord channel, added it as a PAM module, and opened SSH on port 22 to the internet. It's quite entertaining.
Raspberry Pi 4 Model B (4GB) - Using it as a Plex Media Server on Raspberry Pi OS (formerly known as Raspbian).
Recently, I've tried to install Anbox + Google Play on it, but it didn't work well, crashed too many times so I gave up. I guess it will remain a Plex Media Server for the rest of its life
While I still only own a 1B? Collecting dust.
When I get my hands on some 4B's and the other materials I need to prototype (and time to actually work on said prototypes)? Products for the two most important things in life: Coffee and orgasms.
I have two 1B collecting dust. I feel like I need to buy a 4B but I'm afraid it will collect dust like the others 😂
Turn that 4B into a dusterbot for the 1Bs.
I have an 8GB 4B which I use for PiHole plus backing my NAS up to the cloud . It also posts drive info about itself and my NAS to my Pi3 where I have a crude and ugly dashboard telling me about space use.
My Pi3 also connects to the NAS, but syncs the data to an external hard drive.
I use an old model b with 512 mb ram, it runs archlinux-arm, i use it as mpd server, webserver (lighttpd) IRC supybot, bitlbee and the obligatory tmux session, cheap to run so always on 24/7, also uses cron to post random tech stuff to twiter via some scripts i have written using xstartlet. makes a fine home server.
Good job on it 😎 I need to get one too, I guess it was fun to build it 🤩
yes fun is one word, however in the early days of 'alarm' frustrating was the more apt adjective.
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.
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 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
I have a lot of Raspberry Pi boards: 2 x Raspberry Pi 4 boards (8GB and 4GB) 1 x Raspberry Pi 3 B+, 1 x Raspberry Pi 2, 1 x Raspberry Pi 0W.
I have two Pis set up as retro gaming consoles: A Pi 4 in the NESPi case, and a Pi Zero W in a Gameboy case for a portable retro gaming console.
Aside from that, I use my other Pi 4 for a basic Linux desktop. And my older Pis are used for stuff like a smart home hub with Hass.io, ad-blocker with Pi Hole, 3D print server using Octoprint, and a VPN server. Have a Pi Plex server I made for my uncle too, ripped his small DVD collection to digitize it, put it on a flash drive, and spun up a Pi NAS.
I have a Pi 3B running the obligatory Pihole, a Pi 4 as a Jenkins server (running on Java 11 but compiling Java 14 apps, which was no cakewalk to set up!), another Pi 3B running InfluxDb to capture actuator metrics from Spring Boot apps, a launch day, eight (?) year old, original Pi Model B running Media wiki for documentation (although using a mySql instance running on my NAS box) and a Pi 4 running LibreElec that my wife uses as a media server.
All but the LibreElec one are in a couple of rack mounts.
I use mine for a couple of things:
I wrote a small Node app that records my Twitter followers vs my friend's Twitter followers daily. I launched it in May because I was gonna try to beat his follower count and I wanted to track my progress. Since then, he's gained something like 400 followers and I've gained 4.
WordPress's WP-Cron doesn't run at an exact time because it'll only fire when WordPress actually receives a request, so any time I need one of my WordPress sites to run a regular job, I set up a cron job on my PI to curl the homepage of the WordPress site.
These need a persistent connection to the Internet to be sure they run everyday, but I'd feel silly throwing such trivial apps on a Digital Ocean droplet. The Pi is perfect for this.
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 have a few Pis around my home office.
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.
I have a Raspberry Pi 2 B + which I use for a small web server with a couple of Laravel applications. At some point I used it with Asterisk with my own VoIP system.
At this moment he is taking dust in a corner hoping that I will find some work for him
You never know when the necessity arises 😉 And in urgent situations it could be a life-saver 👍
This one's good!

This is awesome, way to go! 🔥🔥
PiHole for blocking ads & trackers
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.
All I have created is a web server which serves the live feed of the raspberry pi camera.
Tbh, I didn't know they made separate components as well 😉
Came across it while sourcing info for the discussion intro 👍
A Pi2 and Pi3 running as local webservers. Working quite nicely.
Home media server + smart home management mostly. github.com/agneevX/server-setup
Using a 3b + with a Pi Hat and two 1TB external HD for a Nextcloud install.
I have rpi 3b+ . And I use it as arcade.
I run Scrapy on mine for web scraping!
I have two of them
I have 2 currently. One is a 2b that I use with an ADS-B usb stick that feeds flight tracking data to radarbox.com. The other is a 3b that’s currently running PiHole for adblocking, dns and dhcp.
I've got my Pi4 as a present just recently.
So far I played a song on a piezo buzzer and made RGB LED rainbow dance :-)
But I'm really interested in making a magic mirror with it.
magic mirror is great!
i set mine up to display world clock, hour-by-hour weather forecast from yr.no, pollen count and the local buses and metro status.
the pi runs chromium as a kiosk, and connects to the node.js backend which runs elsewhere in docker. i was too lazy to put it in a mirror tho, its just a bare screen.
Unifi controller
Pi-Hole
Wireguard VPN
I want to change it to make it a node in the kubernetes cluster I have running on my NAS and run all the things above in kubernetes
Pluma can handle more tabs, but I don't need more than 10 open files.
Firefox consumes much more memory than Pluma.
1) Cluster of eight Pi 3B I've been using for a while.
2) Cluster of eight Pi 4B I just recently set up.
Using them for parallel genetic algorithm research.
As an IoT device at the company I work for. RasPi is used to extract data from modbus meters and then you can put it anywhere you want through the web.
That was an interesting read 😉
Thanks for documenting your journey 👍
