How am I only now discovering this excellent lecture series on analog electronics by @abovenyquist?https://youtu.be/ge6ds1HM7BE

I started watching this 2008 EE lecture series because folks said it's really great and I want to know what makes a great EE communicator and I'm a bit under the weather. Answer: just say everything I've ever wished someone would say. Such as:https://twitter.com/starsandrobots/status/930619138426339329 …

"You know what's dumb about most circuits books? So you have a circuit. 1V source. 1Ω resistor. 1F capacitor. 1H inductor. WHAT IS GOING ON IN THIS CIRCUIT??" yessssss I used to tear my hair out over this.https://www.youtube.com/watch?v=8pOgPWFaDRk&index=3&list=PLXnFQqfHz_iHvvUlt5jV162WUmvnzpoLa …

"Now how do you figure this out? Do NOT go write 50 circuit equations. That is NOT how people do engineering."

"You need to know about operational transconductance amplifiers (OTAs). They are extremely useful." "Also engineers think in terms of Z (impedance) but Y (admittance) is often far more useful. So is conductance."
I've always wished someone would just say it.Show this thread

TBC: this class is analog electronics through the context of building synthesizers. A 1F cap has no real business in any example. He also explicitly doesn't really discuss power electronics. It's all good.

Also, I want to see that 1F capacitor!

Right??

Let me guess: Tesla coil?

I'm pulling for inductively heated hot tub but I'm betting your guess is right

Oooh or world's lowest-frequency subwoofer. For that ELF Bass.

With that much H you could use a rack of space heaters as resistors.

Griffiths’s E&M book remarks a naive 1F capacitor would be moved by forklift. He used to bring to class one a non naive one a reader...

...mailed him along with a little Matchbox dump truck to move it in as the sender couldn’t find a suitably sized toy fork lift.

I've known educators who literally burned themselves building a demo voltage divider with a 9V battery, a 1 Ohm, and an 8 Ohm resistor. Learning with practical values matters.
