Early access: How do CRCs work?
Here's the latest video on error detection!
CRC (cyclic redundancy check) is one of the most common methods of error detection. It uses some interesting mathematical tricks to guarantee that it can catch certain kinds of errors. How does it work?
I'm curious if people enjoy these theory-heavy videos as much as the build-a-thing videos. With the theory out of the way in this video, the follow-on video to this will be almost entirely hands-on. My personal preference is leaning towards doing more hands-on stuff in the future, but since this is a very theory-heavy video, I'm curious what you think?
Also, let me know if you see any issues with the video. Plan is to release ~Sunday.
Thanks,

I like the theory too, and seeing this relating back to math is fascinating
I found these and have been watching very much because you go heavy on the theory as well as the practical aspect. If I just want to build, I've got Lego. I love what you're doing!
I personally am here for the learning and the fun. So if you keep the videos separate that would work best for me!
TTL - you mean "Time To Live" or "Transister-Transister Logic". If the Transisters, I'm in!
I particularly like the theory. Maybe it's just because I'm a little older, but after a while the 'build-a-thing' part isn't as interesting because that's not where the new things are being learned or taught. Of course it's always satisfying to build some CMOS or TTL thing on a breadboard and see it actually working. That never gets old. But what new thing is really being learned if there isn't some theoretical context behind it? Keep up the excellent work and please don't be afraid to teach the underlying theory ahead of the 'build-a-thing' part.
It is a bit heavy on theory, but I found the approach amazingly clear and streamlined, by deferring the hard part and slowly building towards it, not skipping along the way was very helpful. And Having a sneak peek on hands-on video was like a cherry on top, made me feel like all this theory was worth it. The "shifting leds" in that sneak peek confirmed the theory visually :) Great video, explanation skills and very informative!
These types of videos are perfect, each builds on the last towards the complex concept. It might start getting a bit long for some with a 58 part series on sha-256. :p
