In CDs (please correct me if im wrong) dents are used as a differentiator (so if light reflects it will be 1 if it dents 0, Im sure sure if the correlation is correct tho).

I have a computer engineering degree and 10 years of work experience but I find your videos so amazing that I find myself watching them even about things that I already know. BTW I was so fixated and hypnotized by the way you move the mouse cursor and how smoothly it's done that I had to backtrack a section of the video several times because I was only paying attention to the mouse hahaha you make it seem so effortless like "I'm recording my screen just moving the mouse and talking" and I'm not sure but I'm under the impression the mouse is scripted or smoothed (great work! That's very hard to achieve and takes a lot of work and attention to detail). Anyway, your video is extremely easy to follow, and that's a huge and great thing because there is an immense amount of people trying to teach these concepts and yours has definitely stood out as the best, most beautiful, and easiest way to learn.

Hey Sebastian. I know I'm 2 years late to the party, but I just recently discovered this series of yours, and following along has been a blast! I'm curious by nature and have always wanted to understand fundamentally how computers work, so upon discovering your videos and the simulation tool you've made available, I knew I'd struck gold. I've sunk 10s of hours into grasping how each logic gate works and how stringing them together can eventually result in a functioning computer. I haven't even gotten to the later videos in this series, but I've already learned so much that I want to thank you for doing all of this. You're amazing!

I love the videos in this series. I got the simulation, and it really helps me understand what you are saying even better, which is saying something because you explain everything extremely well. Just one quick suggestion for the sim: Make players able to delete chips, preferably by right-clicking, which would bring up a small button to delete. I made a 4 bit adder, but then realized if I was to ever use it in even bigger calculators, I would need to add a carry in input (something I neglected to do). Now I have two adder types, and the first one isn't worth having, but here I am.

@rutvikpanchal466
@rutvikpanchal466 3 роки тому
The moment i saw memory in the title, The microprocessor subject from my engineering course rushed through my mind and i immediately wondered if you included the infamous race condition and what happens when the power turns on when both the NOR gates are off in SR latch. Also i think you should have also included what happens if both the set and reset are HIGH at the same time.
@SheepUndefined
@SheepUndefined 3 роки тому
Uh, I'll bite! What would happen in that last case?
@rutvikpanchal466
@rutvikpanchal466 3 роки тому
@@SheepUndefined in that case both the outputs Q and Q' will go LOW (using uppercase due to typing convention for bit states) which shouldn't happen in terms of logical properties we have assigned to the outputs. As the Q' is the opposite of Q both being the same value breaks the logic hence that state is considered an invalid state where the output of the latch isn't considered. In real world this never really happens because logically only one input of S or R is allowed to either SET or RESET the latch. You can map how both the outputs go LOW using a pen and a paper, start with any one input and you'll slowly see how the outputs go LOW. You can also map this just by looking at the latch but it might be difficult to track. For reference you can check out SR Latch video by Ben Eater. His entire series of 8-bit breadboard computer is a goldmine of knowledge and i am genuinely amazed by the effort he puts in all of his videos to educate people all around the world for free (Think about it, cutting out wires to exact size necessary to provide crystal clear presentation of circuits!). His youtube channel has taught me more than my college on that subject. Same goes for many many creators on UKposts, @Sebastian Lague obviously being one of them.

@@rutvikpanchal466 I ran into that in a game of Factorio while trying to implement a combinator circuit to disable a train station for an oil patch that didn't produce much and avoid sending the oil train off on the long route to it when there wasn't enough available to make the trip worthwhile. I eventually got it working properly, but not without partially dismantling things to get it into a stable state. I think it got into the glitched state when setting up the combinators that provided the set and reset signals.
