Windows can not handle Raspberry Pi filesystem
The SD card has a filesystem called Ext4. For a large number of reasons, involving fights for technological power, a lot of money and different technological camps that we have in the world of technology the Windows operating system can not by default read the file system Ext4 that our current SD card is using. It's a pretty interesting story why. We should probably do another whole course on the history of technology, but for now, we just need to know that Windows does not support Ext4 and that's why we must use and additional software tool to fix this.
Additional software for reading Ext4 file system
There are a number of different additional software tools that we could use to read/write information from and to the SD card when using Windows. We are not connected with any of them and you can basically choose any of them.

A nice article that we found on how to use them is located at https://www.howtogeek.com/112888/3-ways-to-access-your-linux-partitions-from-windows/
You can explore all of them, but let's use Paragon for this particular example
Paragon Drivers
Download and Install Paragon Drivers. It will require administrative privileges.
After installing place the SD card in the computer and two new devices will be shown in Windows Explorer
Open rootfs, locate the /etc folder and the hostname file in this folder
Edit the file hostname with notepad. Right Click, Select open, Search for Notepad and select notepad. The file will be open with notepad.
Change the
raspberrypi
to
Change this line to
MyNewName
Where "MyNewName" is the new name for your Raspberry Pi.
After completing do not forget to unmount (eject) the SD card
If you don't the file will not be written and nothing will be changed.

Perfect STEM course. Module 1 - Smart Car with Raspberry PI
Disassemble a remote control car. Change the brain of the car with a smart computer like Raspberry Pi. Build a smart device with artificial intelligence that you could control from your phone and that could freely navigate itself in the real world and on the Internet. Use your hands. Develop programs for your robot and your phone. Be curious and invent.
The perfect course lives up to its name. You move through the content, we check it and return feedback to you.
In the end, you should be able to better understand how to program and design smart devices that would make the world a better place. For everybody age 12+, 16+, 21+, 35+, etc. The hardware costs about 150$. It changes through the years so it might take some time for you to find it as Raspberry PI, motor drivers, power banks and h-bridges.. they change. Note that the course was designed to be led by a teacher with a decent knowledge in embedded hardware and software. This, on the other hand should not stop you, if you are curious.

Configure Raspberry Pi name
When connecting to the Raspberry PI you will see it on your phone with a default name of "PerfectPi". You can change this name to something that you would like. Actually, you should change the name to something else to learn how this name could be changed. With this tutorial, you will learn some pretty interesting hacks and a thing or two about file system
