Compared to nano or vi, which is generally all I'll use on a RPi, it's pretty heavy.

Thanks Basil.  I was not aware of this. While VSCode is a fine editor, it's a bit heavy, and I can go download it and install it if I want. I don't need a microsoft repo added.  Though how far we've come from the days when Microsoft had all out battle against *nix.

Anyways, this is the output I got:

pi@ve7tgz-draws:~/n7nix/bin $ ./block_msvscode.sh
Test if Microsoft repo has been configured
grep: /etc/apt/sources.list.d/vscode.list: No such file or directory
  Microsoft gpg key and repository entry NOT active
  No files edited Microsoft repository already blocked.

I think I'm clean.

You can view the reddit discussion here:

https://www.reddit.com/r/linux/comments/lbu0t1/microsoft_repo_installed_on_all_raspberry_pis/

If you do an 'apt-get update' and see the Microsoft package line then
you already have the update with the added repository which looks like
this:

sudo apt-get update
Hit:1 http://packages.microsoft.com/repos/code stable InRelease
Hit:2 http://raspbian.raspberrypi.org/raspbian buster InRelease
Hit:3 http://archive.raspberrypi.org/debian buster InRelease

This is what an apt-get update looks like without the Microsoft package

Hit:2 http://raspbian.raspberrypi.org/raspbian buster InRelease

I personally do not want to access a Microsoft server every time I do an
update on my RPi and I really don't want it on my headless units so I
wrote a script that removes that "feature". For more information please
look at the reddit link above.

My script lives here:
https://github.com/nwdigitalradio/n7nix/blob/master/bin/block_msvscode.sh

Get the script in the usual manner:

cd
cd n7nix
git pull
cd config
./bin_refresh.sh

When running the script with an argument it displays the status of the
Microsoft config without editing any files. This is what it will display
if you have the Microsoft "feature".

cd
cd n7nix/bin

./block_msvscode.sh -
Test if Microsoft repo has been configured
File: /etc/hosts has NOT been edited
File: /etc/apt/trusted.gpg.d/microsoft.gpg exists and is NOT empty
File: /etc/apt/sources.list.d/vscode.list IS active

If you run the script without any arguments it will edit 3 files which
will block the Microsoft Visual Studio repository update.

./block_msvscode.sh
Test if Microsoft repo has been configured
Microsoft gpg key or repository entry IS active
0.0.0.0 packages.microsoft.com

I purchased the "suggested/recommended" fan and prepped it with

Hoping that someone else has already figured out the appropriate size

The DRAWS case was designed to accommodate a standard 30mm fan (24mm spacing on the mounting holes).  Although I have not purchased these myself, this pair from Amazon are marked with the same p/n (LD3007MS) as was on the original fan used during the case design/update:

Does the hat allow the pi to be gracefully shutdown when attached to a

Yes the DRAWS hat has everything required to do a graceful RPi shutdown.

It has an A/D converter that measures the 12V source voltage.
Periodically reading that voltage with cron you can detect when your
vehicle is turned off going from alternator to battery. There is an
example on how to do that in this script n7nix/tracker/updown_log.sh.

You read the output of 12V with the sensors command and
peel off the number you are interested in.

From a console run the "sensors" command to see the output you are
dealing with. From the updown_log.sh script the following line extracts
the 12V value.

voltage=$(sensors | grep -i "+12V:" | cut -d':' -f2 | sed -e 's/^[ \t]*//' | cut -d' ' -f1)

To do a compare in bash I want the voltage as an integer so I get rid of
the plus sign & decimal point

volt_int=$(echo "${voltage//[^0-9]/}")

I use the volt_int value to detect when I need to gracefully shut down the RPi

if (( volt_int < 1300 )) ; then
sudo /sbin/shutdown -h now
fi

Instead of an APO3 I use a Powerwerx ITS-12. For the APRS app I use a
fork of Dan Smith's dantracker which runs in a browser. In my vehicle
I run a hostap on the RPi and connect over WiFi so that I can use my
phone or tablet as a display.

There is a nixtracker thread here:

My mobile setup currently has everything running through an
APRSworld.com APO3 that automatically cuts power to everything
downstream of it 10 minutes after seeing the drop from alternator to
battery voltage. I'd like to have the ability to gracefully shut down
the pi, after say 9 minutes (thus before power is cut off by the APO
device), and the additional capabilities your hat provides interests
me, especially the ability to control 2 radios.
