Issue 71, Page 23 under Android Zero:
Unfortunately, Android Things does not support the Pi Zero – it requires a bit more power than the board can currently provide, so you’ll need at least a Raspberry Pi 2 to run Android Things on, but preferably a Pi 3
This statement is incorrect. Android Things only supports the Raspberry Pi 3 Model B. It will not run on a Raspberry Pi 2.

Issue 71, Page 75, line 35 of listing, wind_speed.py -

print( calculate_speed(wind_interval), "cm/h")

Should be "cm/s".

Hey there! I've just noticed that in issue 75 of the magazine, both number 36 and number 30 in the top 50 voted projects have the PolaPi-Zero's name and description. It's nothing major, I just wanted to let you know.

Issue 87 Power Up Your Kitchen

The first part covering temperature and alarms - page 69. In section 03, there is a reference to some Python code "... download the code file temperature.py ..." but no indication where that file is located.

Issue 98 - article "build the ultimate home music system".

This is part 3 , and I have to say it's a great project - I built a couple of Rpi4's from part 1 and 2 of the article series, and works great.
I run into problems with the issue 98 part 3 instructions :
step 02 and step 03 show command line to use starting with command "get"....I think this should be "wget"

get https://github.com/badaix/
snapcast/releases/download/v0.20.0/
snapclient_0.20.0-1_armhf.deb
sudo dpkg -i snapclient_0.20.0-1_armhf.deb

Also, the commands shown for step 03, to install the snapcast server, are identical to the commands in step 02, installing the snapcast client.

I think for step 03, should be :

wget https://github.com/badaix/snapcast/rele ... _armhf.deb

Also, further on in step 3, it says the /etc/mopidy/mopidy.conf file should have

[audio]
output = autoaudiosink

However, in the part 1 of the series, contained in issue 96 , step 06 instructs to set
the /etc/mopidy/mopidy.conf file to:

[audio]
output = alsasink

So I'm a bit confused about this [audio] setting...

Continuing on to step 4, setting up the snapcast, I'm not sure what is wrong.
I edited the /etc/mopidy/mopidy.conf file per the instructions in step 03, and followed the step 04 instructions to get the snapcast service "connected"....BUT now the audio playback does not work for Iris. However if I open another tab on the browser, and go to a streaming radio station ( http:/www.wcrb.org ), the audio stream plays fine there.

Why not read the package documentation at
https://github.com/badaix/snapcast

&
https://docs.mopidy.com/en/latest/config/

Rather than the crudely transcribed junk in the MagPi magazine.
Any language using left-hand whitespace for syntax is ridiculous

Hubble spelling error

Sun Feb 07, 2021 4:22 am

In the article by @RosemaryHattersley boldly titled "Hubble Pi" there is a spelling error;-

The Hubble Space Telescope is a catoptric Ritchey–Chrétien with hyperbolic mirrors, not a catadioptric Maksukov with spherical mirrors and lenses.

The telescope featured in the article is difficult to identify from the photograph apart from being cassegrain, but described as "rather small" may well be a Maksutov.
