Buried inside a PiDP-11, connected to a VT420. Used mostly for IRC. Though I am considering using it to build a bedside radio/clock/alarm that doesn't report back to FAANG.

#12I'm running a Twitter bot that tweets out sunrise/sunset timelapses, and also does on-device object detection and classification to tweet out helicopters that fly by the field of view.

It's a Pi 4B with the HQ Cam (6mm lens). The ML models are trained on my MBP, converted to tflite, and run on the pi itself.
The main use case is the timelapses, but after seeing that that most of the helicopters that flew by weren't transmitting ADSB, I figured I could help out the @helicoptersofdc crowdsourcing project (run by someone else) by contributing heli spots in an automated manner that might otherwise go unreported.
I also have a 3B+ running pihole on the LAN.

#13I have a 4 by my wireless router doing DHCP, Pi-Hole DNS ad-blocking, and hosting a Wireguard tunnel.
I bought a nice case and M.2 SSD for it, and it has been running happily for almost two years.

#14I use it as a media player for my daily workout (I used DVDs before) :-)

#15Learning. Right now I have my Pi running a Python script that will grab messages placed in an AWS SQS queue and scroll them across an LCD screen attached to the Pi via breadboard.
For me, projects like this make learning something I am not all that interested in but required to use for work (in this case SQS) much more fun because I get to learn something that interests me (in this case getting an LCD screen to work with the Pi)

#16I've got one of mine collecting weather data https://github.com/bediger4000/station I'm hoping to detect the "tide" in the atmosphere with barometric pressure readings, but I haven't done anything towards that. I'd also like to have an automated way to pick out high/low temperature for the day. I've got 2 thermometers taking temperatures. There's data loss caused by both sensors quitting and operational issues, so I…
I'm doing something similar on my rpi3, but indoor. A few environment sensors + a basic thermostat script to control my box-fan-in-the-window-plus-smart-plug "HVAC" (not that its been anything interesting as far as control during the summer: ON). Data collection is mostly temp, CO2, and PM since I can somewhat calibrate those, plus pulling down the 24 forecasts from NOAA twice a day, all into a sqlite DB with grafana on top. I'm hoping to get some exterior sensors running as well, maybe off a zero or something smaller, but we'll see.
Bonus points, I can tinker with some probably over-complicated timeseries python classes for sqlite.

#17Printer server for turning a dumb printer into a network printer.
Sensor and pump control for a self-watering flower bed.
I used to run a server with my unifi controller, NAS gateway, and IRC server, but I found an old office PC that does that for me now with about 10x the performance.

#18I'm using pi's for these works:
1. A pi 4B running jellyfin and aria2c. I use aria to download files, torrents and stream them on jellyfin. I have a aria2 web frontend for using it from browsers.
2. A pi zero wh running pihole.
3. Another pi zero wh for nginx

#19Raspberry Pi B: Stream a local ham radio repeater (weather spotters) to Broadcastify
Raspberry Pi Zero: Brachiograph
Raspberry Pi 4B: Octoprint
Raspberry Pi 4B: Home Assistant
Raspberry Pi 4B: NAS (running Kopia as backup target w/ USB HDD, not speed-critical)
Raspberry Pi Zero 2W: ham radio-related software for portable use (e.g. WSJT-X, etc.) using cell phone via WiFi as display/input via RDP
To do: MiniDexed synth module, eInk display driver, network a UPS via NUT, RetroPie, Ham Clock, etc., etc. I've also used them previously as a fax server, digital signage for office lobby, and other things I'm forgetting

Can you explain the first usecase in more detail to me? I don't understand what's different in it compared to normal downloading.
