I bought a Pi 0 W. The USB port failed on it. Sent it back, the second did the same. Booted probably about 10 times in all. That was the end of that.

#353I don't have a project yet -- but one I'm really interested in is having a Raspberry Pi run and store historical data from an air quality (particle) measurement sensor. I'm hoping to measure how the air quality outside my home (near a freeway) changes during the day and night with traffic, and also how the indoor air quality is impacted. It outputs UART 9600 baud data ( https://sensing.honeywell.com/honeywell-sensing…
Have a look it at https://luftdaten.info/en/home-en/. Not exactly using an rPi, but the goal of the project seems to fit with your plan.

#354I have several of them:
* 1 original model that runs pi-hole for the household
* 1 RPi 3 running RetroPie for emulating classic video games
* 1 RPi 3 connected to an official RPi touch screen display that runs a Home Assistant UI
* 4 RPI 3s running as a Kubernetes cluster, mostly just for the fun of setting it up, but I have a few odd jobs that run on them, such as chat bots
I don't have a picture of the cluster all hooked up, but this is what it looks like without any cables attached: https://twitter.com/jimmycuadra/status/846935997619200000

#355Not using the Raspberry Pi yet but have been exploring the idea of using it as a way of delivering our educational content to rural areas of Zambia.
Idea would be to provide enough information in a booklet to get students to a point where they can power the pi and then teach them the basics of electronics and coding by building a power monitoring system, with the pi at the heart.

Re: Ask HN: What do you do with your Raspberry Pi?
#356My work has a really old phone system which I became the admin of. I discovered it had an audio input for Music-On-Hold, so I set up a spare RPi Zero that I had as a music player so that we'd have hold music. Low effort but wonderful improvement for work. Every now and then I go back and tinker with it to improve it a bit. (Next step is to make it controllable via a web interface.) I have a RPi 3B+ that I use for som…
Did you also acquire an ASCAP/BMI license for the music-on-hold? A lot of people are unaware that is classified as a public performance of the music and requires a license. Unless you are playing royalty-free music, in which case you are fine.
I purposefully sought out royalty-free music. As the person who set it up, I did not want to risk being culpable for anything. (When it was first set up, my boss kept requesting that I add various catchy songs he heard on the radio to it, and I kept having to explain it's not legal.)

#357Earlier quoted context omitted.
I'm interested in this too. It would be even cooler to link these CO2 sensors into Apple's HomeKit somehow...
I have been using Home Assistant to integrate everything. I have Google flavored, but it also has HomeKit support. https://www.home-assistant.io/components/homekit/
Thanks for the tip!
Home Assistant has a module for the "MH-Z19 CO2 Sensor" (1) which is on AliExpress for $20 (2). So i'll probably give that a try...

Re: Ask HN: What do you do with your Raspberry Pi?
#358I love and hate this question! I've always been curious what others do with them, but I just convinced myself not to buy a 4 and I'm sure this thread will give me reason to reconsider. -1x Raspberry Pi Zero W in my garage running my drip irrigation (a relay board connects it to standard 24V irrigation solenoids) -1x Raspberry Pi 3 B+ in my office running a dynamic dns script and sitting behind a forwarded port for ea…
>>1x Raspberry Pi Zero W hopping between my garage and car running a program that collects and displays OBDII and GPS data
This is what I also want for my car. I am planning to collect the GPS and car data and answer the eternal question I have .. Which road to work is more efficient in time and gas. :)
Re: Ask HN: What do you do with your Raspberry Pi?
#359My aspirational goal is to make a "mission control" panel for my kids - basically take a bunch of panel mount buttons and switches and combine it with an old monitor to make a fun toy! The Pi would control the monitor but I will need to add/design an input/output board to handle the buttons and switches.

#360Unpowered in a drawer.
If yours has wi-fi (Pi 3 and above or Pi Zero W) you can always just leave it plugged in somewhere innocuous as a pi-hole. It's super useful and takes almost no time to set up, provided you can change the settings on your router to use it as DNS.
I'm scared that if the pi is down then the whole internet is down (i'm not always home with my family, so if I'm away I couldn't fix it).
How do you manage failover ?
