    Raspberry Pi Imager update

    Reading Time: 2 minutes

    Just in time for the holidays, we’ve updated Raspberry Pi Imager to add some new functionality.

    • New submenu support: previous versions of Raspberry Pi Imager were limited to a single level of submenu. This limitation has been fixed so we can group images into different categories, such as general purpose operating systems, media players, and gaming and emulation.
    • New icons from our design team: easy on the eyes!
    • Version tracking: the menu file that Imager downloads from the Raspberry Pi website now includes an entry defining its latest version number, so in future, we can tell you when an updated Imager application is available.
    • Download telemetry: we’ve added some simple download telemetry to help us log how popular the various operating systems are.

    You can go to our software page to download and install the new version 1.5 release of Raspberry Pi Imager and use it now.

    We haven’t done telemetry in Imager before, and since people tend — rightly — to be concerned about applications gathering data, we want to explain exactly what we are doing and why: we’re logging which operating systems and categories people download, so we can make sure the most popular options are easy enough to find in Raspberry Pi Imager’s menu system.

    We don’t record any personal data, such as your IP address; the information we collect allows us to see the number of downloads of each operating system over time, and nothing else. You’ll find more detailed information, including how to opt out of telemetry, in the Raspberry Pi Imager GitHub README.md.

    You can see which OSes are most often downloaded too, on our stats page.

    As you can see, the default recommended Raspberry Pi OS image is indeed the most downloaded option. The recently released Ubuntu Desktop for Raspberry Pi 4 and Raspberry Pi 400 is the most popular third-party operating system.

    This Raspberry Pi–powered setup improves home brewing

    We spied New Orleans–based Raspberry Pi–powered home brewing analysis and were interested in how this project could help other at-home brewers perfect their craft.

    When you’re making beer, you want the yeast to eat up the sugars and leave alcohol behind. To check whether this is happening, you need to be able to track changes in gravity, known as ‘gravity curves’. You also have to do yeast cell counts, and you need to be able to tell when your beer has finished fermenting.

    “We wanted a way to skip the paper and pencil and instead input the data directly into the software. Enter the Raspberry Pi!”

    Patrick Murphy

    Patrick Murphy and co. created a piece of software called Aleproof which allows you to monitor all of this stuff remotely. But before rolling it out, they needed somewhere to test that it works. Enter the ‘Danger Shed’, where they ran Aleproof on Raspberry Pi.

    The Danger Shed benefits from a fancy light-changing fan for the Raspberry Pi

    A Raspberry Pi 3 Model B+ spins their Python-based program on Raspberry Pi OS and shares its intel via a mounted monitor.

    Here’s what Patrick had to say about what they’re up to in the Danger Shed and why they needed a Raspberry Pi:

    The project uses PyCharm to run the Python-based script on the Raspberry Pi OS

    “I am the founder and owner of Arithmech, a small software company that develops Python applications for brewers. Myself and a few buddies (all of us former Army combat medics) started our own brewing project called Danger Shed Ales & Mead to brew and test out the software on real-world data. We brew in the shed and record data on paper as we go, then enter the data into our software at a later time.”

    Look how neat and out of the way our tiny computer is

    “We wanted a way to skip the paper and pencil and instead input the data directly into the software. Enter the Raspberry Pi! The shed is small, hot, has leaks, and is generally a hostile place for a full-size desktop computer. Raspberry Pi solves our problem in multiple ways: it’s small, portable, durable (in a case), and easily cooled. But on top of that, we are able to run the code using PyCharm, enter data throughout the brewing process, and fix bugs all from the shed!”

    “The Raspberry Pi made it easy for us to set up our software and run it as a stand-alone brewing software station.”
