I'm using one as part of a midi controller project:

http://jsnow.bootlegether.net/jik/keyboard.html

The controller has 156 pressure sensitive keys. The raspberry Pi runs a program that reads from a bank of 20 8-channel ADCs all wired up to a SPI bus (it runs at 2mhz, and I'm able to get about 90 samples per second), and then generates MIDI commands that are sent over a USB-MIDI adapter.

I could use a microcontroller for this, but it's kind of convenient to be able to plug other USB-MIDI devices into it and have it work, and to be able to run a Linux-based synthesizer locally if I want. (I've been planning on using a Teensy for the next version.)

I have a pair of Pi Zero Ws set up as timelapse cameras that I keep in the garden - Cucumber vines and flowers opening is pretty interesting at 1 frame per minute

I recently did a project with a pair of RPi 3b+ and cellular modems as construction cameras.

I set up RetroPie on a 3b+, but it wasn't enough for the N64 games my wife and I wanted to play the 4 could change that

Currently my security cameras are recorded using Orchid VMS on an Odroid XU4 ( Cloudshell with 2x 4T SATA)

Its a great little tool for learning Bash, and groking your systems - testing portability? - without invoking AWS resources.

I have 3 running right now 1x Raspberry Pi model B (from 2012!) - runs a reverse proxy to things in my local network, and runs a dynamic DNS service. It's showing its age as its ARMv6 and I guess at some point updates won't be as frequent so will eventually have to retire it, but it works fine for now. 1x Pi model 3 - runs various services, inc. GOGS a private git server, ZNC, a service to control my TV, a service to…

Do you have any more information or a write up on what you're doing with Twilio and voicemail? That sounds sort of interesting.

You can actually do voicemail within Twilio for free using their TwiML Bins and Functions, you don’t need any extra hardware to maintain.

Just did this for a couple of numbers I set up with SIP. The docs were... confusing and inaccurate but I finally got it to work.

1x Raspberry Pi 3B+ running OctoPrint, velcro-attached to my printer.

2x Raspberry Pi 2B running OSMC (with Kodi) for streaming from NAS to office TV and living room TV.

1x Raspberry Pi Zero W running OSMC (with Kodi) for streaming from NAS to bedroom TV.

Provided HEVC H265 decoding works as it should, I suspect I will eventually upgrade all 3 of these to Model 4. They're great for a media center -- low power, small, and provide a local-only player for TVs I don't want to connect to any network.

Also have 2 OG B+ models that sit in a drawer unused, since they don't have enough power for the above tasks.

- Hosting personal website from my DMZ at home.

- SDR and packet radio (Direwolf) projects

- Kodi

- rpi zeroW with usb serial for connecting back to my house from work/travel.

I had more projects, but I've been able to replace them all with ESP8266's. Rpi is overkill to do simple things like toggle a gpio pin or take temperature readings. Use it if you have it, but it's nice freeing up extra rpi's with a $2 ESP.

I use a RPi Zero W to run DakBoard: https://dakboard.com/site which my family uses to organize our life.

I'm planning on adding another Pi as a Pi Hole device as an experiment in parental controls via low TTL values to provide scheduled access to specific DNS names. For example, my kid gets distracted beyond all that is reasonable by Discord and I'd like to let him use Discord, but only at specific times. Anyone with an interest in this, please let me know!

What do you use for the camera? I have some plants I'd like to monitor but the cameras I'd use always ended up dying due to the heat.
