Background: I took some 100 and 200-level courses on electronics in college over a decade ago. I still remember some stuff (Ohm's law, Kirchoff's law), and I can recognise the basic parts in a circuit diagram.

I am also happy to pick up a beginner friendly text book and go through the theory by myself, if there are any recommendations.

However, I've never even held a soldering gun. I am a blank slate when it comes to any practical applications. I get overwhelmed trying to figure out what kit to order on Amazon.

So, is there a course/tutorial you'd recommend for learning the hands on parts of it? I'd prefer as much handholding as possible. Ex -- if someone sells all the components to finish the projects in the course that would be the course I pick.

It's not as big a risk as this person is making out. If you're playing with low current microcontroller stuff, there's virtually no risk. At most you're gonna let the magic smoke out of a chip, not start a fire.

If you start getting into stepper motors and things like that, sure, but that's a long ways from where you are today.

Where does something like "use a DC motor to build a tiny little fan" stand, in terms of safety?

Very safe unless you attach razor blades to the blades.

Most small DC motors don't have enough power to break the skin

Awesome, thanks!
