I have an old Raspberry Pi 1 that runs headless raspbian with a set of cheap speakers plugged into it and an old usb wifi adaptor. It has only one purpose: to play a wav file of a telephone ringing for one minute. My spouse does not ever have the ringer on her cell phone. So when I am out and I need her to look at her phone, I VPN in to my home network, ssh into the pi using Terminus on my iphone, and 'aplay' the wav…

I would have presumed you can have custom notification levels for specific phones calls baked into modern phones OSs.

iOS has a bypass list for “Do Not Disturb” mode, but sound is disabled via a hardware switch next to the volume buttons.

As a workaround, I’ll use the “Find my iPhone” chime which is the one way to bypass the hardware switch if I need to get my wife’s attention while the phone is set to silent.

With an amazing team, I'm helping run a fleet of a few hundredish pi3/3b+ and hundreds of pizero-W cameras in an evolving automotive IoT solution. It's definitely been a challenge using them in volume, but they've been surprisingly reliable once you control for things like heat dissipation and get a decent networking solution. (At our scale we're approaching having to decide if we want to be a MVNO.)

take a look at my project at cattlepi.com

RPi2: Hass.io, switches the lights and reads my electricity/gas usage from mqtt. RPi1B: sends smart energy/gas meter values over mqtt to RPi2. RPi3: Recallbox, mainly for Mariokart 64 and GranTurismo 2 with my son but also does Kodi. Probably will be replaced by a 4 soon :)

You could automate this even more with a Twilio number, ngrok running on the Pi and a small webserver to trigger the audio playback. Then instead of having to ssh in you can just send a text.

Is ngrok the new dnat?

Expose your server endpoint to the public web however you like. There are lots of options and many have been discussed here recently. I just happen to be a fan of ngrok and use it daily for all sorts of cases, including on some of my Pi’s.

Fairly pedestrian uses.

One running OSMC (Kodi) media server.

One that manages nightly backups for all the machines on my network. Does wake-on-LAN as needed, uses rsnapshot to encrypted external drive. I also run Pi-Hole on this.

Have one in the office that serves as a terminal server via X2Go. Let's me remote desktop to office machines as needed.

I'm quite a fan of DietPi as my distro to use on these. I also use Ansible as much as possible to configure and manage them.

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

This would be a good application for a Pi Zero W (with WiFi) - if you want to collect the data in a central location. I've linked the CO2 sensor I used in another comment.

Yep - Pi Zero W's for the sensors reporting to a Pi 3 for aggregation and reporting.

I currently have three around the apartment attached to the network:

One running Seafile (https://www.seafile.com/en/home/) with an old laptop hard-drive connected via USB enclosure. It acts as my own Dropbox. I mainly store notes and photos on it and sync them to a few other devices for redundancy. It also has a Samba share with all of my music and has an open vpn server so I can connect to it from anywhere.

One with a HiFiBerrry Digi+ hat (https://www.hifiberry.com/products/digiplus/) connected to my sound system via toslink running an MPD (https://www.musicpd.org/) server. I can control it with M.A.L.P. (https://play.google.com/store/apps/details?id=org.gateshipon...) on my phone. This one also has a 7" touch screen (https://www.amazon.com/Raspberry-Pi-7-Touchscreen-Display/dp...) which I use to sometimes display ncmpcpp (https://github.com/arybczak/ncmpcpp) inside edex-ui (https://github.com/GitSquared/edex-ui). This one also acts as the living room clock with an USB LED message board (https://www.amazon.com/818-Dream-Cheeky-Message-Board/dp/B00...) controlled by dcled (https://github.com/Conservatory/dcled).

Another with a GPIO breakout and breadboard with an individually addressable LED light strip attached. I got the idea from this Adafruit tutorial (https://learn.adafruit.com/light-painting-with-raspberry-pi/...). I wrote a program in Python to make it softly glow between random colors and sync to any beats-per-minute.

Short answer: I've got one sitting behind the TV in my parents' kitchen, running ssh and openvpn for proxy/vpn purposes, but mostly working as an automated BBC TV downloader, scripted to download a list of shows every night, at different qualities (e.g. don't need high frame rate for quiz shows), rsync them to my server at home outside the UK, and send me a PushBullet message to tell me what will be available to watch over breakfast. Works beautifully!

I'm very tempted to get a 4 and pair it with a lower-specced NAS for home server purposes - I don't think even the Pi 4 has quite the I/O to be a great storage server by itself, but that combo is probably more fun and flexible than just a NAS alone...

> 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 Can you go in more depth about this? How did you integrate it with the entertainment system, and what do specifically do you do with it?

I am not the person you asked but some ideas, in order of most complexity/cost to least.

- Some kind of CAN bus hack. They exist.

- He has a ford and hardware that can interact with openXC CAN2-2 see here: http://openxcplatform.com/vehicle-interface/hardware.html

- He's using bluetooth.
