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

A filtering DNS server is much easier to add into your network - don't have to play with proxy autoconfig, and because it's not mucking with the http content, very lightweight.

I was bullish when I got my first Pi to run Home Assistant (before hass.io), but got discouraged when the sd card failures were gas-lighting me by silently reverting my code changes. That and the lack of hardware clock hampering some of the diagnostic tools I usually use, kept me sticking with VMs on a NUC and a fanless Celeron for Kodi for my main compute uses.

In time I have gotten more Pis, but mainly for hardware aided projects such as the Pidp/8: https://obsolescence.wixsite.com/obsolescence/pidp-8 The rejuvenated Nabaztag: https://www.ulule.com/le-retour-du-nabaztag/ The seasonal Xmas tree hat: https://thepihut.com/products/3d-xmas-tree-for-raspberry-pi And a Mycroft Mark I: https://mycroft.ai/mark1/ which is Pi based inside and the only one these projects which is always powered on.

The 4 seems like it may finally have the horsepower to make me try to give it a go again and possibly replace my various x86 pucks as they age out.

We used a few to power kiosk touch screens and other commercial display applications using network broadcast video.

Made a seven screen display each with their own pi that sync’d individual videos running on each to create some video art pieces.

Also made a bullet time rig with 15 pi’s and each with their own webcam. There was a guy who did this already with lots of documentation but using his own pi-interface hardware he created. We did it without the pi controllers.

Using several Raspberry Pis to monitor CO2 levels in my house. Each Raspberry Pi has a CO2 sensor - wrote a little Python script to retrieve data from sensor and upload it to a server Which is also a Raspberry Pi.

I'm also interested, although my curiosity is more about what you are doing with the data.

Just storage? Some sort of charting? Graphite? Maybe some other data monitoring tool? Maybe something custom?

1) PiHole 2) Wired one into a rotary phone to make a weird steampunky smarthouse controller (Dial '0' to turn off all downstairs lights and music, etc) 3) Various LED controls for fun, and Christmas 4) Always experimenting with MycroftAI to stay away from Alexa

I forgot about Mycroft! Thanks for the reminder!

Use a small software defined radio to listen to ADS-B messages (real time airplane telemetry— even with a crappy $10 USB SDR dongle I can sometimes see planes that are 100+ miles away) Host my website (if I ever got any actual traffic it might be a problem, but since 99% of the traffic is me it's ok) Various web scraping/archival tasks

I have been working on my own hosting as well and I wonder where the tipping point is, and if it's in regard to multiple users at once, or just consistent website hits?

I have it set up to run a project where a subreddit has control over the watering of a live plant in my apartment.

The pi runs a reddit bot that reads the votes, and can switch on a pump to water. It also collects data about sunlight, moisture, temp and humidity to help inform the decision about watering. Despite many people's preconceptions about the goodness of the internet, I must admit that they do a wonderful job caring for my plant!

One Pi 3 running Pi-hole: One Pi 3 hosting a Picroft instance; One Pi 3 with a camera to experiment with simple video capture; One Pi 3 and several Pi zero W's on a custom network ( the Zero's act as temperature sensors in different rooms, reporting back to the Pi 3 as a control node; eventually it will be running our HVAC).

I use it to take up space in my drawer of useless electronic stuff because I can never find a combination of power supply and SD card that doesn't eventually end up corrupt and unbootable.

You could try not buying cheap components. Storing it in a drawer probably doesn't help either.
