My 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 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…

Uart is just serial, you’d connect it to your serial pins on the pi and read serial from Linux like normal. Data is whatever the protocol Honeywell is using. Could be any range of things sent in a predictable pattern. Could be timestamp,temp,air quality,status, and then some kind of delimiter like newline or eor. Note the pi devices use 3.3 volts instead of 5 so you have to make sure Honeywell is not sending too much voltage as a logical high. There’s probably an easy way to convert it though using a voltage devider.

How much do those sensors cost?

I work for the Raspberry Pi Foundation, in the Education team.

We're always on the look out for new ideas and projects to turn into learning resources.

If anyone would like to share their code, wiring diagrams and setup processes, then please feel free to email me.

1. RPi 1B (256 MB RAM) as my home phone/voicemail system, using Asterisk PBX (with FreePBX). Have used it since it first came out. 2. RPi 1B+ as a car media server with minidlna using a USB WiFi adapter. 3. RPi 2B as an ownCloud server. 4. RPi 3B as a LibreELEC (Kodi) media (streaming) center. 5. RPi Zero W. No use yet.

I have used the 3B for RetroPie as well in the past. I am planing on using a RPi for different kinds of webscraping in the future. I would also like to set up a NAS/backup server.

Four things:

1. Pihole to ad block ads (useful for phone browsing) https://pi-hole.net/

2. Custom Weather conditions dashboard, using Dark Sky's API

I'd love to replace the weather dashboard with one of my integrated work / personal calendars so I could see what meetings I have each day but work won't expose that data, claims it's a security risk.

3. Custom NYC subway dashboard, showing me estimated train arrivals for trains at the 2 closest stations.

The MTA has free apps which also show estimated train arrivals but only for one station at a time. Also, the MTA's train estimation methodology isn't as accurate as it could be.

4. Retro Pie, to play NES and SNES games https://retropie.org.uk/

I run a grid of about 250 Pi 2 and 3s across several offices and datacenters. They are the backbone of our graphics playback system (i.e. slates) and low latent IPTV system. Users can subscribe to any channel necessary without expensive re-encoding or RF antenna systems. I absolutely love them and 4k60 HEVC is a huge upgrade for the 4!

Tell us more! My team is currently looking for a digital signage option that would include cable/IPTV of some variety.

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

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

FlightAware in particular gives you access to a greater level of data and services on their site if you're an active contributor via a PiAware. Also, honestly, it's just fun fooling around with the antenna and software setup to maximize the number of flights I can see :)

A client that I'm consulting was being ripped off by a local IT provider with pricing for on-premises servers & MS software. I proceeded to rent cheaper equivalent machines off-site. The IT provider claimed the hardware firewall (Fortigate) was not configurable for site-to-site to the new machines directly (could be, not an expert on those). Therefore, I ended up purchasing several Raspberries and configuring them as…

Fortigate is pretty configurable. I’d be really surprised if it couldn’t do site to site or site to client with a little configuration.

I'm kinda concerned by the number of mentions here of using the Pi to run OctoPrint (I think that's right?) to remotely admin and monitor a 3D printer... I've always been of the mind that a 3D printer should never be left physically unattended - even with monitoring (via camera and such), as they can potentially start a fire if something goes wrong (failed print spewing random filament?). Is this a wrong viewpoint? A…

I wonder when we will see the first 3D printer that can validate what it is printing via some camera and image recognition software.

And maybe even correct errors it made a second ago ;-)
