@@SebastianLague computer topics are typically so bland and obviously technical. Having these sorts of satisfying animations really help with making it enjoyable to watch!
@@TechCircuitBreakdownIt makes sense since you only need simple AND and NOT gates to make all of that, which can be done in Minecraft thanks to redstone...
A series about electronics would be real cool, you could expand your current program to take voltages into account and add resistors and such to make it more similar to a breadboard.
I'd definitely love to try making a simple electronics simulation! I'd probably keep it separate from the digital logic sim though, since I also like the simplicity of that.
@@SebastianLague Also would be nice to add transistor logic. I am currently using a program called Logisim Evolution to make a 16 bit computer at the transistor level. I have considered writing my own program that would better handle transistor logic but I have no idea how to do that.
Please Sebastian, Continue with this series they are so easy to understand and THEY ARE SO CALMING AND I UNDERSTAND ANY SINGLE WORD COMING FROM YOU PLEASE I BEG YOU CONTINUE WITH THIS 😢😢😢😢
One thing i've always wondered was how the simulation tool itself worked, maybe that could be an interesting video, I'm especially interested about how you save modules that you make and how they are represented in their save files.
Hi Sebastian, you probably won't see this but I LOVE your videos. They inspire me to code, thank you for being my inspiration, and favourite youtuber. :)
Please Sebastian continue this series! I learned a ton already and I can't wait until you get to program counter, control unit, instruction decoding, etc
You are a gift from God to us. Being an electronic engineering student, I have learned more information from your videos than my 3 years university classes. Thank you for this amazing series and I hope it will continue that way. God bless you. 🙏♥️
the reason the chip has 2 store enables is because that way you could use a row select and column select (for example) without needing a seperate or gate to combine them yourself, it's just a convenience thing
This series is honestly amazing. When learning stuff like this in school, they are nothing but boring information, but when presented this way, everything changes. I don't know why, but seeing all these components work with each is very satisfying. Regardless, amazing series and I cannot wait to see more.
I like how this series is basically a presentation on my 300 level circuits courses in college. Real blast from the past, and highly educational. PSA if this grabs you, consider a Computer Engineering degree!
Absolutely loved this episode. When you put that calculator together and showed it storing numbers, doing basic calculations and displaying the results, I finally saw the computers we have today emerging. Awesome stuff!
Thanks for "showing the world" how simple the computer really is. For others: the input signal he generates in the final stage is an assembler instruction (move data from here to there, prepare data to be counted, store the result over there and so on...). Your normal programming language instruction C = A + B gets translated to "move A and B memory locations to input, make their sum, move the output to C memory location" and the only meaningful difference between Sebastian's simulation and your computer is the scale and scale related optimizations.
Hey Sebastian! I know you probably won’t reply but I just wanna say that you’re literally my biggest inspiration in life. I just made a solar system simulator because I loved yours so much. Thanks for everything :D
I've never seen it all put together like this before. When you wired everything up at the end and started (essentially) running CPU instructions by hand, I got goosebumps. Just beautiful.
I bookmarked this playlist so long ago, and just realised you've added new videos to it. Your content is amazing and I'll be grateful for anything more that you decide you have the time and energy to release! Thank you!
I really hope you continue this series. I'm super excited to continue learning about all the complex things you can create from just some simple chips wired together in clever ways
When talking about the 4 bit register, i think there are 2 reasons for the store signal and data out signal having 2 pins. Firstly, the 16pin dip package is a lot more common then 14, so we likely have those pins anyway. Secondly, when you talk about the issue that 2 chips could output onto the bus at the same time (14:11) this can easily be solved with those 2 pins. If you give each chip a different combination of not gates before their data out, it acts as a mux. A could have no not games, B could have a not on pin 1, c on pin 2, and d on both. Giving you the same inputs as when you had the mux chip. Then they can no longer output at the same time since each chip has an unique combination of inputs to enable it
Yeah, usually (at least the few chips I have worked with) you get multiple chip selects/out enables to save you a few external and gates. Sometimes you even get one inverted (active low) and one non-inverted because this makes external selection circuitry easier. Also for registers having multiple inputs can sometimes allow easier "stacking" (not really the formal term I think but basically using more than one chip in parallel to increase the bit width or similar), because in these cases some select signals might differ (only have a 8 bit bus but want to work with 16 bit data in this calculation? Easy! Have one "global/external" store connected to one write enable pin on both chips and the other one connected to a toggle latch. This way the first clock pulse will latch the first 8 bit in the first register and flip the toggle latch so the second clock pulse will store the second 8 bit set in the second register.)
I've always been interested in building my own 8 bit computer in video games with logic gates and eventually building one in real life. I've watched Ben Eater's channel which is absolutely marvelous in explaining complex details. Your channel has been a good buffer for me as sometimes watching other videos on the topic gets complicated quickly. You explain everything so well and the visualizations really help so so much with my understanding of the topic. Thank you for these awesome videos!
Sebastian, you have been doing the god's work, teaching us how the computer works by simplifying everything which goes on inside. I hope you continue this and keep on working on the simulator software so that other engineers and students can experiment on different circuits.
You're a hero! This was such a good series. The way you demonstrated everything on your simulator, which was designed to be very easy to read, made this really easy to follow. Also, it's cool that you actually made a simulator and didn't just draw diagrams.
This series is just awesome, I can't wait to see how far you'll go. Also, I can just hear your smile in your voice and it's really awesome, I wish all people were this enthusiastic about the things they teach
Finally! An update to the series that taught me college level stuff in the 4th grade.. I love this series and would love more of these videos. Thank you Sebastian, for fueling my nerdiness.
I have very little understanding of what's going on, but the editing quality, visuals, and your calm voice make these videos so enjoyable to watch. Thank you so much for this series and all the work you put into it.
This series combined with the game Turing Complete makes it perfect to understand and put into practice how a computer (or microcontroller at the moment) works.
I absolutely love these videos. I've been following this series since the first episode. Recently, I finally decided to download digital logic sim, and I spent the day building up latches, and flip flops, and registers, building up adders, and bigger adders, and bigger adders, making an ALU, making various sizes of RAM, a simple counter, and I was able to assemble them all together into a functional 8 bit computer! It was some of the most fun I've had in months, and I'm so proud of how it eventually turned out. There are still some things that I could do with it to improve it. It's not the best 8 bit computer, but it's mine. I built it gate by gate, chip by chip, and I'm very happy that I did. I hope you continue to develop Digital Logic Sim, and I hope you continue to make these videos! They're a wonderful resource to help people understand how computers work in a very fun and understandable way!
Love these videos so much Sebastian. You have such an incredible way of teaching, in such a clear yet intriguing way. I'd love to see more of these. :)
You sound like you're in a calm, understanding, teaching smile throughout the narration. It brings a calm, along with the music, that makes me feel like learning.
The mouse movement was definitely automated in some way, not sure if it's actually a part of the circuit simulator code or some other program that automates the mouse, but it's too smooth to be real inputs
The instruction format in this case is really funky: 4bit - external memory/stack/input in red, 4bit - read address in blue, 3bit - operation type or store address in indigo. But you can make an instruction decoder and design something more elegant if you want to, just grab the software and make your own. What the circuit in the video really needs is more explicit branching with a comparator. But you'd probably add a small stack and stack pointer with that, to make sure it's Turing complete. At this point the circuit simulator devolves into a CPU architecture designer with no way to synthesize the design.
I just love your video, I played a lot with logic gate when I was younger making CPUs in minecraft etc and your software is one of the things I was missing when I started playing arround with thoses logic gate, so glad some child would be able to learn and play at the same time with you clear video and software that all combine are just pure gold ! continue doing those video I just love them and you are so pationnate about it we can clearly see it (edit sorry for bad writing I'm french my english not perfect)
For anyone intrested in this kind of electronics there is free project course called '"Nand To Tetris" on Coursera. In this course you build a whole computer starting only with a NAND gate. It's suprisingly easy to follow!!
Just happened across this series today and i'm loving it!! Your voice is so soothing along with the music in the background. And your explanations are done in a way so that someone as illiterate as i am on this side of things can follow along. Can't wait for the next one!!
my jaw dropped in the final few minutes, seeing the culmination of everything so far working flawlessly. this series is so brilliant, thank you for all of your effort!! (and thank you for the subtitles. i have some speech-comprehension difficulties and really appreciate well-crafted subtitles :] )
couldn't you use a 2 bit number to encode the 4 output selection bits so that illegal states (two outputs selected the at the same time) and bus congestion become impossible?
Yes, that would solve the issue of bus contention, but would limit your design to only working for 4 registers. This approach (while somewhat more "risky") allows for much greater modularity.
I'm literally studying Microprocessors right now, so seeing Seb catch up to my course material is so exciting! I never in a million years thought I'd love electronics so much XD
This series is amazing. You made an amazing visualization tool and these videos explain so many ideas on the basics of computers so clearly and concisely. I'm excited for the next video in the series.
Please, continue with this series. It's so well explained. Just found your channel and it's just so well done. Congratulations and thank you very much for this explanation!
That disconnected state blew my mind. I literally paused the video and just fathomed it for multiple minutes, likening it to different revelations like that in different fields such as there being a fourth state of matter plasma, or how there's multiple types of infinities some bigger than other infinities, or back to science molecules not being the fundamental smallest thing and then atoms not being the smallest thing because of quarks and quantum mechanics. I think it's obvious I really like revelations like these thank you so much for sharing one with me. I mean seriously more than two states that a computer uses on a fundamental level?? I'd also like to thank you for the manual transcription, how else would I know it's nybble not nibble, and of course more importantly how would hearing impaired or deaf or blind (through the use of text to speech on actually correct subtitles) be able to enjoy this masterpiece.
Just found this series and it is great! I enjoy how it focuses on the theoretical part (not having to worry about timings or electronics too much) but also mentions the more practical problems as well. Great work
As a computer engineer this series is amazing, if only Digital Electronics was taught in this manner, considering what we want and testing different means of achieving such a goal creates great intuition, definitely continue it!
oh my goddd I love your work man!! this video was amazing!, I was thrilled when you finally turned the whole thing into a calculator xDDD amazing, keep it up please
This is so awesome! I wish we had these at school so we can practice at home, without the need to worry about wires and chips flying around. And the ability to bundle up logics into your custom chip is just amazing.
The visuals on these videos are so good. Concise, yet unambiguous. I already know all of the stuff this series covers, but the videos are just so well made, relaxing, and satisfying. It makes me really wish I had these videos when I learned this stuff to begin with.
For anyone interested in knowing how an ALU would get its input from the 4 bit data bus, there is a special purpose register called the accumulator (AC). The AC is by default one of the inputs of the ALU (in 1 address instruction based architectures), as well as the the place where the output of the ALU gets stored. So whenever the computer needs to add two numbers, one of the operands being inside the accumulator, it would send the other number to the 4 bit data bus which would then be received by the ALU as the other operand in the next clock pulse. And the result of this operation would then be stored in the accumulator for future use. Thanks Sebastian for this lovely video!
Four in the morning, my guy. You're lucky adore your content. I was just thinking about going to bed, and here you are tempting me with a distraction. Oh well. I suppose it can wait!
I've been a software engineer for like 7 years at this point, and I've always abstracted in my mind the behaviour of this low level components... this is the first time that I get to understand how all of this works from the bottom up, and it's SO cool. Be sure that i'll send a lot of people your way, because this is pure gold.
This series blows my mind every time, the way you can expand from and/or/etc to build something of a calculator! Never would have understood that before.
This series and your simulator need to be in every classroom. I learned these concepts in grade 10 electronics class (30 years ago - I went to a "tech" high school) using components breadboard and I can't imagine how many more students would have more easily grasped the concepts using this software instead of spending half the class time trying to debug misplaced wires. Great job!
This video is so visually smooth and informative. With this new context I think I can finally understand those "bus wires" on the Minecraft mod ProjectRed

That disconnected state blew my mind. I literally paused the video and just fathomed it for multiple minutes, likening it to different revelations like that in different fields such as there being a fourth state of matter plasma, or how there's multiple types of infinities some bigger than other infinities, or back to science molecules not being the fundamental smallest thing and then atoms not being the smallest thing because of quarks and quantum mechanics. I think it's obvious I really like revelations like these thank you so much for sharing one with me. I mean seriously more than two states that a computer uses on a fundamental level??
I'd also like to thank you for the manual transcription, how else would I know it's nybble not nibble, and of course more importantly how would hearing impaired or deaf or blind (through the use of text to speech on actually correct subtitles) be able to enjoy this masterpiece.
Just found this series and it is great! I enjoy how it focuses on the theoretical part (not having to worry about timings or electronics too much) but also mentions the more practical problems as well. Great work
I have messed around with your simulation and every time I see one of your videos on it I get blown away by how perfect your lines are
As a computer engineer this series is amazing, if only Digital Electronics was taught in this manner, considering what we want and testing different means of achieving such a goal creates great intuition, definitely continue it!
I've had computer engineering training yet never saw a better teaching of the hardware side anywhere. Beautiful.
oh my goddd I love your work man!! this video was amazing!, I was thrilled when you finally turned the whole thing into a calculator xDDD amazing, keep it up please
I hope that part 5 will be coming out soon, love this series so much! :)
This is so awesome! I wish we had these at school so we can practice at home, without the need to worry about wires and chips flying around.
And the ability to bundle up logics into your custom chip is just amazing.
The visuals on these videos are so good. Concise, yet unambiguous. I already know all of the stuff this series covers, but the videos are just so well made, relaxing, and satisfying. It makes me really wish I had these videos when I learned this stuff to begin with.
For anyone interested in knowing how an ALU would get its input from the 4 bit data bus, there is a special purpose register called the accumulator (AC). The AC is by default one of the inputs of the ALU (in 1 address instruction based architectures), as well as the the place where the output of the ALU gets stored. So whenever the computer needs to add two numbers, one of the operands being inside the accumulator, it would send the other number to the 4 bit data bus which would then be received by the ALU as the other operand in the next clock pulse. And the result of this operation would then be stored in the accumulator for future use. Thanks Sebastian for this lovely video!
Im a big fan of this series! Because its simplicity it's very easy to follow, can't wait for more!
Four in the morning, my guy. You're lucky adore your content. I was just thinking about going to bed, and here you are tempting me with a distraction. Oh well. I suppose it can wait!
I could honestly watch these videos all day just because of how satisfyingly smooth the mouse movement is.
I've been a software engineer for like 7 years at this point, and I've always abstracted in my mind the behaviour of this low level components... this is the first time that I get to understand how all of this works from the bottom up, and it's SO cool. Be sure that i'll send a lot of people your way, because this is pure gold.
I literally made a noise when I saw a new video from you in my sub feed you always are so inspiring to me.
This series blows my mind every time, the way you can expand from and/or/etc to build something of a calculator! Never would have understood that before.
This series and your simulator need to be in every classroom. I learned these concepts in grade 10 electronics class (30 years ago - I went to a "tech" high school) using components breadboard and I can't imagine how many more students would have more easily grasped the concepts using this software instead of spending half the class time trying to debug misplaced wires. Great job!
The quality of this video is incredible!
This video is so visually smooth and informative. With this new context I think I can finally understand those "bus wires" on the Minecraft mod ProjectRed
