Local Computer Science Teacher Fooled by Fake Iain Armitage YouTube Channel
by Dave Briccetti
Local computer science teacher Dave Briccetti thought he was chatting with the real Young Sheldon actor, Iain Armitage, on a YouTube channel called “Iain Armitage”, and on Mr. Briccetti’s own channel when the imposter subscribed to it.
Briccetti showed his students at one of his schools that “Iain Armitage” had subscribed to his YouTube channel, and they were quite excited. Briccetti tweeted about how excited the classes were, and @mentioned the real Iain’s Twitter account.
Iain’s representative, who manages the account for him, saw this, and very kindly contacted Briccetti via Twitter private message to let him know that he had not, in fact, been communicating with the real Iain, and that the only YouTube channel belonging to Iain is Iain Armitage: Iain Loves Theatre.
Mr. Briccetti was very annoyed that he had been tricked, and set out to expose the impostor and get the YouTube channel shut down. He wrote the following as a reply to a recent posting on the fake channel:
“Don’t be fooled. Iain has nothing to do with this channel. It’s fake. Ian doesn’t do social media, according to his people.”
Iain’s lovely but credulous fans would not believe Mr. Briccetti. You can read much of the conversation.
Before long, Mr. Briccetti had the evidence he needed to convince the fake account subscribers that they were interacting with an imposter. Iain himself made a video which Briccetti shared with those subscribers. Only then did they start believing.
Many of the subscribers then reported the channel to YouTube. Iain’s representative told me it had already been reported to YouTube, but no action had been taken.
Less than a day later, this is what appeared when visitors attempted to return to the fake Iain Armitage account on YouTube:
How to Use a Servo Motor
Some of you will use a servo motor in your interactive pet, Hot Wheels track, or other projects. Mr. Briccetti shows you how to program it.
Reporting Progress on Your Projects
Each time class meets:
- If you’re working on a multi-day project (Hot Wheels track, interactive pet, etc.), update a Computer Science Project Status report. To create the document (once for each project), go to Google Drive and create a document using the template Computer Science Project Status [your name]
- Submit a Student Progress Report.

Wi-Fi is not the Internet
The Internet is a worldwide network of computer networks. Many Internet users connect to the Internet via a cable modem, which is connected to a Wi-Fi router. Individual devices connect to the router via cables or via Wi-Fi. If accessing the Internet is slow, you may not know whether it’s Wi-Fi or your connection to the Internet that’s the problem.
How to Save and Load Your MakeCode Projects
Hi, all. If you’re finding that your MakeCode projects aren’t being automatically saved to your computer’s web browser, or you want the ability to work on different computers over time, you can create a sharable link that you can use later to resume work on the project. Look for the share icon (next to the house icon) at the top right of the MakeCode web page. When you get the link to your project, save it somewhere, perhaps in a document or spreadsheet in your Google Drive.

Mr. Briccetti bought himself a Creality Ender 3 3D Printer.
3D Printing
The process:
- Create something in a 3D modeling tool like Blender or Tinkercad Designs
- Export it for 3D printing (usually creating an “stl” file)
- Load the file into a “slicer” program such as Ultimaker Cura
- Save a “gcode” file onto an external drive
- Put the drive into the 3D printer
- Tell the printer to print the piece

- a 3D-printed gate (with arm)
- a micro:bit

- a servo motor
Procedure
- attach the gate to the track
- download the Timed Gate Controller program onto the micro:bit
- connect the micro:bit, breakout board and servo motor
- mount the servo in the gate, but don’t attach the arm (the part that moves up and down) to the servo yet
- push A+B on the micro:bit to start the open/close sequence, in order to ensure the servo is at the right angle when you attach the arm
- attach the arm

Random Password Generator in Python
from random import choice # Make the choice function from the random module available for use
from string import ascii_letters, digits # Import constants containing letters and digits
def generate_password(length: int) -> str:
characters = ascii_letters + digits # abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789
password = '' # Start with an empty string
for i in range(length): # Loop once for each character to add
password += choice(characters) # Choose a character randomly and append it to the password
return password # Return the finished password to the caller
password = generate_password(12) # Call the generate_password function and save the result in `password`
print(f'Your password is {password}') # Use an f-string to create a message, then display it
Read about the string constants. Read about choice. Read about formatted string literals, or f-strings for short.
ChatGPT Describes the Program
“This is a Python script that defines a function generate_password that takes an integer length as input and generates a random password of that length. The password consists of a mix of upper and lowercase letters and digits.
”The generate_password function first creates a string characters by concatenating the ascii_letters and digits constants from the string module. It then initializes an empty string password, and uses a for loop to iterate length times, each time appending a randomly chosen character from characters to the password string using the += operator. Finally, the function returns the password string.
”The script then calls the generate_password function with a length of 12 and saves the result in the variable password. It then uses an f-string to create a message containing the generated password and displays it using the print function.”
