If you want to learn the process whereby you can make cool stuff too, join in my Creative Engineering class!!

This class is a hands-on, 30-day learning experience that will teach you how to use engineering and science to bring your creative ideas to life.

During this class, I’m going to share with you my entire creative engineering process from start to finish. You’re going to follow along with me as I fully design and engineer 3 brand new builds from scratch… from how I come up with the idea, all the way through bringing the final builds to life.

The best part is, over the month, you’ll follow along with me and my process, side by side, and you will leave the class with 3 original, creative builds of your own.

This is the class I wish I had when I was starting out. It’s designed to take your skills to make cool stuff to the next level, whether you’re a beginner or a more experienced maker/engineer.

See you in class!

      @matthyno there was no racism proven at the trial, not even attempted. They must not have found any. Because if they could have found ANYthing, you know they would have made a big deal out of it. Even if it was an off color joke in a high school locker room. But … nothing. Crickets. They did not prove it was racially motivated. But the entire world was led to believe (falsely) that it was.
      Media lied and people all over the world lost their minds and so many people died because of it. GF’s life was not worth all that death.
