Electronics has and likely always will feel like arcane magic to me



Get this book:

https://www.opencircuitsbook.com/

It’s a book featuring macro photographs of cut-aways of electronic components. It’s the first book that helped me really think of electronic components as a physical things whose function followed from physical principles, rather than an arcane collection of various bits of black magic strung together.


I agree! I kinda know nothing about electronics since "my first electronic kit" as a 8 year old, and that book of cutaways shocked me as how many things in my computer aren't nanoscale magic!


Windell Oskay & Eric Schlaepfer's book has brilliant photographs and insightful text ... a coffee table book to delight any techie. They slice through connectors, semiconductors, and components ... showing the wonderful microscopic world of everyday electronics. A real joy!


That's why one of the best books on high speed digital electronics is titled High Speed Digital Design: A Handbook of Black Magic [1]

High-speed digital and RF are more "magical" than a lot of other forms of electronics. It is quite a bit more approachable if you limit yourself to ~200 MHz signals at most, then you don't really have to worry about the RF properties of your circuits as long as you keep the wires pretty short.


Especially when you think about what electronics are made of: things mined from the earth. They made rocks compute for us!


Where else would they come from, the moon? It's to be expected that for large scale products like computers to be made from common materials.


My favorite bit of "electronics magic":

(this has more to do with TFA and impedance-in-general than might meet the eye at first glance)


It’s a beautiful demonstration of how increasing one parameter (frequency) can successively invalidate whatever model you’re using for the system, where negligible errors in the model eventually become functional circuit components.


frequency exposes the efficiency of transmission through a material.
