CAD CHALLENGE- TO DESIGN A RING THAT FITS ONE OF YOUR FINGERS!!
Bonus: add a cool design!
I'm Jon Barber. I'm a UVa grad, I make, repair, and learn tech/comp sci/media with middle school students near Charlottesville, VA. The Force is with me, but I am not a Jedi ... yet.

Important Links are all on Schoology, like the Daily Slide and our class-shared Google Doc, called "Delicious Biscuits." During the first few days, we go over procedures, readying our laptops and our minds for a safe, fun building environment:
I. Students must bookmark these sites in a "Barber Folder" on their toolbar. (Here's how):

I finally got a Weather Station. Those who know me or have followed me on Social Media know that I obsess about weather, especially snow prediction. Well, I quit all social media associated with Zuck or Musk and now I'm on BlueSky, Reddit, and NextDoor only. BUT, you can now follow me because of my birthday present this year!
My folks got me an Ambient Weather Station WS-2902:
I waited until after school got out to try to install it and mount it and that ended up being a GOOD call. The software set up was pretty quick and easy ... it reminded me of installing my smart thermostat at my previous house. You use its wifi to start off and connect it to your phone. Assembling it was even pretty easy. Mounting it was a little more difficult. You have to have it completely level (there's a bubble on top for you to use to judge), it has to face North, and you have to both have it a little distance from the house, but close enough for Wifi to reach it. Getting it at least 6' off the ground complicates things a little.
My future Father In Law and I got it done in about an hour. Fortunately, he had a perfect metal pole for the job and he had some pole strapping that we used to attach it to a wooden fence pole.
Now, I'm sharing with AmbientWeather.net ... check it out: Link and my station is KVAAFTON89 on WeatherUnderground.
micro:bit is a good basic way to start using microcontrollers. It even has block programming, so elementary students can "code," too! Because my students are in the 7th and 8th grade Mechatronics classes, we use actual code instead of just blocks:

When we use Arduino in the Barber Shop, we try it out on TinkerCad first. This gives a rough draft "try" without having to worry about avrdude/Serial Port errors, AND it gives the coder a good diagram to look at when they are coding IRL:

Mechatronics is Programming a Computer to convert Electricity to Mechanical Energy
What are examples?
In the past,
My class has built and flown airplanes, similar to UVA’s RazorDrone
We have built a Lego MindStorm obstacle course (from ANCIENT Lego MindStorms I found left in one of my rooms)
At UVA, Mechatronics built the HooPrint AND a complete working electric guitar
What other examples can you see in a classroom or think of that are Mechatronics?
