#112Using 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.

#113I run Pi-hole off a RPi Zero W on my local network. Set it up over Ethernet with a bit of cron automation [0] and later expanded Gravity (the blocklist) along with firewall NAT rules to redirect all DNS queries to go through the Pi-hole [1].

#114I built a guitar stomp box using a Raspberry Pi Zero to trigger samples with a foot switch. Runs on 9 volts and has a very bright OLED display so I can still see what it's doing when I'm playing in a dark venue.

#115 - WiFi garage door controller
- OSMC x 2
- Stratux
I had PiHole, but moved it to a tiny VM in an effort to minimize cables.

#116Have any of you done something with machine learning on rpi? Like face recognition or some fun robot. I'm looking at rpi4+google coral and it seems impressive enough to run interesting projects.
I have a script that retrieve photos from an attached camera and then uploads the images to an AWS GPU instance and train an image recognition model there. This is all for controlling my model trains :-)

#117- 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.
I'm interested in learning more about your LED light alarm set up—I had a similar idea a while back but am less familiar with the world of Raspberry Pi.
Re: Ask HN: What do you do with your Raspberry Pi?
#118I use one as a hub/gateway for untrusted IoT devices.
It hosts a separate, isolated wifi network via hostaod/dnsmasq. Clients aren't given routes to the primary network or the broader internet - they should only see the Pi and other clients (I'd eventually like to restrict access to other clients as well, but haven't played with that yet).
Access to the devices is via a web server running on the Pi that relays commands and responses. Right now it's a page full of hard-coded buttons and indicators, but I eventually want to turn it into a flexible firewall-like system to make it easier to add/configure/remove clients and rules.

#119I use mine to run and monitor my 3D printer remotely. I use octopi and the little webcam extension.
Since I have a permanent use for it now, I'll probably be buying a second to play around with.
