I know some projects like Pi-hole and Kodi, but what super cool on Raspberry Pi 4 to install?

Something that hooks up to a real-world API and then does something physical. Like a sign that flashes every time such and such happens. It's a kernel of an idea, but I find all of those really fun.
yeah pretty cool idea!
Mine is directly connected to my router, measures my Internet connection every five minutes and sends the report to one of my servers. Every time I'm facing connection problems and the focking support of German Telekom doesn't believe me I make a beautiful Excel report from my collected data.
Pretty german right 😄
Excellent 🤣🤣
That's great.
Can you share the tool you are using to measure the internet connection?
npmjs.com/package/speedtest-net
That's the package I'm using to measure the connection. I built a HapiJS server which is running a cronjob. After the test the result is sent to a MongoDB on my web server
great, thank you ^__^
Bitcoin mining. Not.
Monero Mining : Yes -> github.com/iayanpahwa/monero-miner
The best thing I ever did with a raspberry was set up a pi hole for a network wide ad block, and Nextcloud to switch my cloud storage, pictures, contacts and calendar from google to my own domain.
I can also see a email server, small-scale webserver or a NAS come in handy.
If you've got something to monitor (Website Analytics, Page Speed, Server logs, 3D Printer, Plant water status) and visualize, Pis are the perfect tool for that.
Or take a look at all the weird black magic Jeff Geerling does.
The PiHole is an instant quality-of-life boost and couldn't be easier to get running.
I've got mine hooked up to my 4k TV. I use it to program on. And I enjoy the irony of having an inexpensive Raspberry Pi connected to an expensive TV.
Since many years my raspberry run yunohost yunohost.org/ and i can do self hosting for emails documents and many other things
that's amazing !! I saw you have a discussion forum as well, ghost I believe?. do you even run that on it ?
Yeah you can see nice apps here (Ghost is present)
Gigantic!! Could it holds the whole Mongodb database?!?!
Ow I don't know for that sorry :/
Are you hosting such a solution and don't know where is your data residing?!
No I know where I put my data, I just don't know if there is a MongoDB app on Yunohost.
I really like Yunohost, I hesitated to use again this good project. Maybe on my other Raspberry Pi 😁
Well, you can install over it portainer and docker and start your homlab!
Or use OpenMediaVault and create a NAS for your home.
Look at this website if you want, it has a lot of interesting projects!

thanks!
No problem man
Make a web server for LAN or even for the internet.
1 is running a music server (I wrote)
1 is running a movie server (I wrote)
An old phone is my remote control.
2 security cameras (pycamera and opencv)
1 security camera hub (use ML to tell if the garage door is open)
1 I use as a desktop for app development
And there is sooooo much more you can do with them
Happy Coding
I'm making a system called "Host Bridge" which is intended to bind a system of headless servers to a UI I'm building.
The UI is a React project and is open-source. Here's a demo: speaker.app/
Cool system!
Thanks!
