- LED Light alarm

- Living room music player & "radio" streamer -- I need to set this up as an A2DP audio receiver too

- octoprint server

- Stratum 1 NTP server (GPS referenced)

If I didn't also have a "big" linux system running 24/7, it would be doing things like DHCP, DNS, MQTT server, etc.

A lot of folks have said "pihole". I have a linux server at home that does my DNS and a bunch of other stuff. I also have a pi3 still in the box. Would there be an advantage to me running pihole on the pi3 instead of on my linux server?

I still don't understand how pi-hole became so popular whereas privoxy didn't

I wrote up a Medium post about what I do with mine: https://medium.com/@adamargo/how-i-use-raspberry-pis-for-hom...

Mostly home automation. 1x homebridge server, ffmpeg transcoder for security cameras, 1x for controlling an electric fireplace using an IR shield and power monitoring outlet, 1x for controlling model train switches and bridging that into HomeKit

There was a time I was super into a project where I had a streaming server that used my Spotify account and would allow anyone with access to the server to change the song. I was basically trying to replicate what Sonos does with a Pi. It worked, but I abandoned it after a few months of not using it.

I'm not really using one regularly right now, but here are the few things I've done with my Pis:

- Hosted a blog using Rails and a Cron that updated the A record on my Route53 domain to point to my local IP address. I'm not sure anyone ever read it, but I had it up for about a year.

- Attempted to reverse engineer a treadmill controller with the UART pins. I successfully figured out the baud rate and captured bytes, but never figured out how to control the treadmill motor board. I have a feeling the motor board had a problem.

- Connected a piezo element to GPIO and made a controllable alarm device.

Nothing that cool, really.

1 - Kids' desktop (Raspi3) 2 - Kodi (Raspi2) 3 - LAN print/automated backup server (Raspi1) I've order a 4GB Raspi4 to upgrade the kids' desktop and 1 GB Raspi4 to upgrade the automated backup server (Gb ethernet + USB3!). Kodi will get the old kids' desktop.

Hi can you share more details on the kids desktop setup? What applications do you use?

Running piAware for flight tracking https://flightaware.com/adsb/piaware/

Is there a benefit to personally tracking flights instead of querying 3rd parties?

Most of the services (FlightAware, Flight Radar 24, ADSB Exchange) get much of their data from volunteer-operated receivers. If you feed your own data to these networks, you get several benefits including multilateration capability (computed location for planes that don't send their own GPS location data) and free business accounts on FlightAware and Flight Radar 24.

Two things, working on more. VPN router and a doorbell to desktop-notifications box. I like listening to music on noise cancelling headphones sometimes when I work. I wouldn't hear the doorbell in that case, so I have a pi with a mic that sits close to the doorbell. If the noise level goes past a certain threshold for a few samples, it sends a command to my workstation where a script sits and triggers a desktop notification. Works pretty well with very few false positives and all "I might miss the package delivery guy" anxiety is gone while I enjoy music.
