FYI, if anyone is wanting some tutorials on circuit design, I took this class this past year, and it was great (back then, we paid for these videos). The software used is called KiCAD, which is an absolutely free and open source eCAD suite of software.

Alternatively, you can use the Altium Designer donation teams get every year, but I find it hard to rely on getting that donation every year.
