Must admit, i saw the title and i assumed where it’d be pointing, as theres been a noticeable overlap in boingboing articles and my youtube feed of late (someone has similar tastes it seems 
)
Wasn’t the case here!
But, in a similar vein, this youtube channel’s playlist 
Where he goes through the whole process of creating an error correction system in hardware on a breadboard and explains it.
Also maybe of interest, from when he builds a breadboard computer from scratch.
Or when he writes a program from scratch on a breadboard computer.
Admittedly right at the far edge of my tech knowledge, in that i can vaguely follow but not fully understand how to do it myself, but i sure find it fascinating

I love projects like this so much. Computers have become so complicated and fast that it’s delightful to see one broken down to its most basic components, running in such a way that you can literally visualize the inner workings and each step of a program’s execution by watching LEDs blink on and off.

Every time I see one of these explainers here on bOing bOing, I think, “20 minutes? No freaking way.”
And here I sit 20 minutes later. Every time.

I met 3blue1brown in person last year. It’s disturbing how clearly he speaks in real life, too.
Hamming’s talk from when he was retiring is excellent reading. One anecdote that has stuck with me is
after I had been eating for some years with the physics
table at the Bell Telephone Laboratories restaurant, fame, promotion, and
hiring by other companies ruined the average quality of the people, so I
shifted to the chemistry table in another corner of the restaurant. I began
by asking what the important problems were in chemistry, then later what
important problems they were working on, and finally one day said, “If
what you are working on is not important and not likely to lead to
important things, then why are you working on it?” After that I was not
welcome and had to shift to eating with the engineers! That was in the
spring, and in the fall one of the chemists stopped me in the hall and said,
“What you said caused me to think for the whole summer about what the
important problems are in my field, and while I have not changed my
research it was well worth the effort.” I thanked him and went on—and
noticed in a few months he was made head of the group. About ten years
ago I saw he became a member of the National Academy of Engineering.
