NOT Gate with Transistors - Will I blow something up?

In this video, I take a deep dive on NOT Gates (inverters). I build my own breadboard RTL inverter, and explore transistor types and logic families to understand the landscape of how logic gates are built.

Circuit.js Diagrams from this video are on GitHub: https://github.com/pagekey/education/...

Despite multiple attempts, I think I still messed up my NPN vs PNP explanation. This video does a much better job:    • NPN & PNP Transistors explained - ele...

If you're getting started, I honestly recommend just buying an Arduino kit - they have a little bit of everything in terms of components. I have one from like 10 years ago that I'm still using (at least some of the components in this video are from it). The starter kit is what I used: https://store-usa.arduino.cc/collecti...
