@@enjoykilian TLDR AT THE END Entrance exams are usually pretty easy. Universities care more about ruling out all the dumb people (relatively speaking) than isolating all the smart people, since universities generally send an application out to X amount of people. Let's say a university accepts 60% of applicants. It doesn't matter if the applicant is in the top 1 percentile, or they're at the 50th percentile (maybe for cost reduction things, but in places with free uni, that's irrelevant, and also most scholarships aren't exam based), they've made it in.

Now, final exams on the other hand are much more difficult because you're expected to know all the content of a class, and are thus expected to be "smart" (also, finals often affect your GPA or whatever your country's equivalent is). However, entrance exams are just meant to make sure you're not dumber than the university wants, not that you're smart. Additionally, many university courses are entry level--- after all, university is a place to learn, not to work (academia doesn't count because you make like minimum wage there). For example, I can take French I at my university: a course with a syllabus that literal 10 year olds could do with the same proficiency as a university student. Similarly, a 7 year old could easily understand "Intro to Programming," because it's another into level course. I don't know what prestige of a university they're going to, but their entrance exam might cover a very wide range of topics at a shallow level, rather than a deep level of a few topics.

That's cool! Redstone is thus an electronic circuit built on OR and NOT gates. Those gates are enough to create the other logic gates as shown. From there you can create any logic circuit, including a full computer.
not exactly there are some other components that make this much simpler I believe it was matbatwings who has a good intro series on digital redstone, there are much simpler versions of XOR gates than this using comparators
Redstone adders are a lot simpler than what was shown. There are a lot more redstone components that could do a lot more than just not gate and or gate. Also you can add BCD format directly so you don't need binary to BCD converter.
@@kazedcat Sure, you can simplify the adder by doing things like removing redundant operations -- e.g. applying two not gates/inverters in a row. You can also reuse data lines. You can use other redstone mechanics (droppers, etc.) to provide additional logic and capabilities. This video was more of an overview/introduction to the topic, by showing the relationship between redstone and electronics and using that logic to build a circuit that could add numbers and display them.
Edit : yeah the approach in this video is a bit...inefficient For those interested : -The machines used to find the "smaller" and "bigger" number in adding are made of* half-adders (takes A+B and gives Sum and Carry). Hook em up as in the video and you get a full adder (takes A+B+Carry_in and outputs Sum and Carry_out). The full_adder can use fewer gates but redstone is already slow so I guess it doesn't hurt much. -When making those "grids/tables" of outcomes from inputs , it is way quicker to find an efficient layout of gates by using "K-maps" which are also kinda fun to do when you learn them

I love when people make really education videos about logic and circuits with redstone. If it wasn't for my curiosity for redstone computing, I wouldn't be majouring in Computational Mathematics today
Superbly done! The graphics are very clear and align perfectly with your descriptions. Your music selection is wonderful and it enhances the narrative.
this is incredible. somehow managed to barely understand everything bc u put it in a simple way and it makes you appreciate how much work goes into a simple calculation
First redstone minceraft video where I can understand logic gates. Loved the video and I'm grateful that you showed how to build the gates, a lot of videos don't show, and I find it amazing
I really appreciated the presentation of this video. The area I enjoyed the most was the fading away of your voice during complex explanations to only be caught up in regular volume during the finally or application of said explanation. I am by no means a programmer or a mathematician experienced in boolian agebra (sp), but this video made following along with complex topics fun. Thank you, keep up the good work.
I'd recommend watching mattbatwings' Logical Redstone Reloaded series as well. It goes much more in-depth with hands-on examples, and makes learning binary logic much more approachable.
I have to like and comment just because of the fact this video is an incredible example of what not only the people who pause and look at this block game then realize "Hey wait a second, I could make a computer outta this thing" is absolutely insane, but the fact that You made this reasonably easy to understand to someone who doesn't even have a strong grasp on the way computer systems work is phenomenal. amazing work
I remember getting really into red stone creations when I was younger. I’d build all kinds of really cool contraptions, hidden bases, traps, block detectors, combination locks, etc. once the command blocks became a thing I just started creating in game plugins like economy systems including a live “stock market” with fluctuating prices for each material, RPG elements, etc. Love it. Still my favorite part about Minecraft.
This channel is honestly exactly what I’ve been looking for for years. I love the visuals, the script, the concepts, the passion in your voice, the things you make. Seriously, these are practically the perfect videos. I would love to see you break down any idea, and I would not mind listening for hours at a time. That is a skill that not everybody has, but you (two?) have mastered it right from the get go. Thank you for the amazing video, I can’t wait to see whatever you have in store next!! :D
Any game that gives the theoretical possibility to build a logic gate, will eventually(if it stays popular enough), result in players building a computer. Building a MIPS processor in Minecraft was probably one of my favourite projects to date
This is literally the stuff we had to do in a course in first semester batchelors degree (computer science). More like a charter, because we ended up making a 8bit-PC. I love seeing all this again. But doing this on your own with the help of the script from the prof was a pain in the ass, when you didnt know what you were really doing
I’m a CS student and this reminds me of an electrical engineering course I took. You amazingly showed the uses of k-maps and so many fundamental topics!!! The elegant showing of the circuitry was so awesome!!! One of my favorite videos I’ve even seen.
11:05 So I don't know if you noticed when building it, but I realized that, since in order to build an AND gate you end up with a big NOT, and you then have to NOT it back in the XOR gate, you could theoretically just. Remove both the NOT gates for a slightly more efficient result.
Oof, this is definitely way smarter than what I did lmao I had a bunch of AND gates that literally produced all of the possible decimals as separate redstone lines. Made the 7 segment section simpler cause you can just place torches in a specific order manually for each possible output, but is ultimately unsustainable if you want to add anything bigger than 9 + 9.
I mean not really? it *sounds* like you used a ROM which would definitely be the more efficient method. Seeing as you built a calculator already and by your own wording, im gonna go ahead and assume you know what a rom is. Ive build a few computers before and in most scenarios regarding 7 segment displays, a rom is perfect. Using traditional binary operations is soooooooo much slower and way larger for (and i can not stress this enough) THIS SPECIFIC GOAL. Roms have a tendency to get big quick when you add more inputs and need more outputs which dramatically slows down speed. Regarding the limited output amount, ive noticed that the best way to go about it is to do the conversions sequentially. just map the locations you want the redstone to arrive at, make a simple counter, and only let the the data travel to the display with the corresponding count (i.e. if the counter is at 6, input the data to 7 segment display number 6). Then just slap an RS Nor latch before every single segment of the 7 segment display and have the display reset when a new calculation is processed. Note that the girl in the video used a BCD converter in their calculator to use multiple decimal values. If you want to do this as well, you're gonna have to do it too. Im not gonna try and explain how but there are many guides online. I wish you best of luck in improving your calculator!
Nah, the rom decoder method for 7 segment decoder is much more efficient than the presented logic gate trees. What you did was faster for single digits. And for multiple digits in decimal logic you just want to do binary coded decimal, then you can just reuse that decoder for each 4 bits.
There's a bit of an error around 7:15 - the order of the columns in the Karnaugh map is wrong. The columns and rows are supposed to be ordered with Grey codes, which is to say that only one bit should flip between adjacent columns or rows, which means you can't have 00 and 11 beside each other. A good order would be 00 01 11 10. In this particular instance, it doesn't make much of a difference, but getting it wrong can lead to suboptimal groupings.
That was an amazing video and the "OMG" at the end slammed me face first back into the tile floor of my highschool AP programming class when the schools antivirus incorrectly identified my C++ program for "life" as a virus and deleted it. My fault for not having a backup but still... Exact same "OMG"!!! Keep up the amazing productions!
@BetaDude40 I'm pretty sure it's grey code that is important and any sequence would work (for example 10 00 01 11). If that is true, using 00 01 11 10 specifically is not required, but probably used has it is the simplest way to convert a truth table into a k-map
You aren't, that is indeed just A xor B xor C, and that's also just how anyone would implement it. The later section offers also two different layouts for the xor gate funnily enough. A xor B == (A or B) and not (A and B) == (A and not B) or (B and not A) == (A and not (A and B) or (B and not (A and B)) to just offer a few versions. When using redstone logic, almost anyone would use the (A and not B) or (B and not A) variant for simple repeater torch logic. It has the lowest delay, and is generally more compact. The 7-segment display logic gate layouts are also silly. Nobody lays those out as separate logic gate trees. You'd just use a 10x7 decoder array instead. It's significantly more compact, and that is what we all did even 10 years ago. Would've been much more interesting to see that concept explained.
@@CensoredUsername_ There was a brief flash of text at 16:18 that explained how a decoder would have been a better option but she wanted to only use gates for the sake of a more cohesive video
If you guys wanna learn more about doing that kinda stuff with redstone, I highly recommend mattbatwings' Logical Redstone Reloaded series. It starts with the basic stuff shown in this video and gets gradually more detailed and complex, but still pretty easy to follow, specially if you do some tests yourself alongside the videos.
Just like transistors aren't on/off but in various states of it. Depending on how robust they are build, you could make a 3 or more state calculation using them. But it is much easier, cheaper and more reliable to just use two.
Well, if I power a redstone lamp with a 15 signal, it turns on, but if I power a redstone lamp with a 1 singal... it still turns on. The truth is, both ways are hardcoded into minecraft, it's just that in most cases, binary (base 2) is just easier to use than hexadecimal (base 16*).
6:00 I can tell you've done actual research because this is quickly starting to sound exactly like my college circuit design classes. And you've done a better job of explaining it than my professors did 😂
I went to check out your other videos and realised I watched the last one too! Incredible content and I'm so glad I noticed this video after getting the last one in my algorithm a few months ago
The fact that you completely skipped over the conversions between bcd and binary is genuinely the best part of this video. I now want to go back to fiddling with logic gates again. Thanks my friend. I will be cursing your name in a month
I feel like this video is more about how binary circuits work rather than minecraft redstone itself. Feels kinda overcomplicated, and a few unique features of redstone had been ignored because they didn't have an equivalent in real life. The 7 segment display part really got me questioning if this is really a redstone video or a circuit video. And the fact that not a single actual redstone was shown (only the 2d perspectives were shown) was kinda disappointing. Still though, this is some amazingly good editing. I love the parts where the lamps turn on and off on the path of the logic gates. That's a lot of explanations too, must have taken a long time to research all of that, very impressive.
Given the title of the video, making the content about how binary circuits work fits very well. Plenty of content about how to implement all of the circuits discussed.
To be fair, there is a pretty significant divide between the computational and practical aspects of redstone. Just like how real life electronics are far more complicated than the computational logic they are driving, so too is redstone more multi-faceted than the circuits here. Minecraft redstone just happens to be a great educational analogue for computational circuitry and demonstrating how discrete math can be implemented. I imagine that for many redstone engineers, there is a difference in skill and knowledge between the "engineering" side making use of BUD power and zero-tick clocks, and the "computational" side scaling huge systems of logic to accomplish complex tasks. Given that Minecraft redstone is both turing-complete and has so much depth in its underlying mechanics, everyone should know a little bit about both circuit logic and gameplay mechanics to optimize their builds. At the very least, redstone is a great educational tool
i think the point of this video isnt how the redstone works, and he does show you exactly how to make each one. making a computer in minecraft is like 99% working out the circuits and planning and 1% actually building it. all this information is necessary to understand how its possible
This is a fantastic video. I absolutely love how you presented the redstone gates visually with the redstone lamps, it was very fun to watch! Your passion is clear from your narration in these videos. I look forward to your next upload!
The amount of transphobic comments on here is ridiculous. Some complaining about voice, literally not a single person on the planet is forcing you to continue watching, nor did anyone ask for the opinion on her voice. And then there's the whole slew of misgendering. Literally, how do you get to that conclusion, her voice is completely fine.
That part i hate here is you sould like you're speaking in a documentary video but constantly in that big reveal voice. Its not bad but being in that tone constantly i personally find annoying. Also its still a net positive for the redstone community.
@@chrispysaid What OP is saying is that OOP sounds like they're always finishing a sentence. Yknow like how people raise their voices when they end a sentence? That applies throughout this whole video.
I must say, I'm only 45 sec. In, yet I already know where this is headed and albeit I know the answer I like the enthusiasm you bring to the idea. In good faith I will finish the video. Cheers Boolean Algebra is fun...
Man I haven’t taken a digital electronics course since highschool. At least I was able to follow along and actually knew some of this; bravo, well done, 10/10 no notes, etc.
I’m a 3rd year electrical engineering student at a highly regarded engineering school, and this video just helped me understand ripple carry adders more intuitively than its every been explained to me before.
This is really cool (and I think electrical engineering), but an interesting potential crinkle is that while redstone components are often binary, but redstone itself is in hexadecimal and a lot of more recent redstone components support this.
I've always been fascinated by redstone computers - I never really got into redstone (despite being a programming nerd) so I didn't realize just how...theoretically simple this all is, if that makes sense? Not to say that this still isn't impressive! And dear gods if you asked me to make a redstone computer from scratch I don't think I'd be able to do it without a lot of time and TH-cam tutorials, but the way you lay it all out in this video is absolutely fantastic because the next step just feels glaringly obvious. I think that's an incredible feat for a technical video like this. Wonderful work
Also, very weak introduction. Computer simulating consciousness? Please do me a favor and begin to write the closing chapter to your life. You have failed at being a man, you have abandoned your life's biological duty.
It pains me to see how unoptimized that adder is. The second half of the ones digit is literally just a second xor gate, but the video never gave an indication that that was the case. In addition, both the ones digit and twos digit had identical xor gated that don't seem to have been merged. Technically, a decoder is just a bagillion gates. A BCD to 7-segment converter is 10 parallel 4-input AND gates, followed by 7 parallel 10-input OR gates. Unfortunately, propagation delay tends to be more important than the number of components, especially in redstone, so such a solution, while far more boring than the shown solution, is usually preferred. That's a lot of effort to convert between decimal and binary, and programmers tend to be lazy, engineers tend to be cheapskates, and neither tends to be willing to put in that extra work to make those converters, and so will just leave things in binary, or if you're lucky they'll work in hexadecimal since it doesn't need full division in order to convert to and from binary.
Make it work, make it right, make it fast. Optimization comes when you have working system and does not really add to the overall approach. So not having that step isnt a big deal.
I could definitely imagine sitting a kid who likes minecraft down and having them watch this and follow along to help teach them all about basic boolean circuits! I really enjoyed the explanation and visuals, this was a great video!!! Also I feel like you enjoyed saying "double dabble" so much, especially when you got to say "To do the double dabble" XD
i know this is rude and i probably could express this in a nicer way but the way you talk is really hard to listen to. im interested in what you have to say but the voice is throwing me off

Redstone adders are a lot simpler than what was shown.
There are a lot more redstone components that could do a lot more than just not gate and or gate. Also you can add BCD format directly so you don't need binary to BCD converter.
@@kazedcat Sure, you can simplify the adder by doing things like removing redundant operations -- e.g. applying two not gates/inverters in a row. You can also reuse data lines. You can use other redstone mechanics (droppers, etc.) to provide additional logic and capabilities.
This video was more of an overview/introduction to the topic, by showing the relationship between redstone and electronics and using that logic to build a circuit that could add numbers and display them.
@@tone618At least we have a 1 block t flip-flop.
Although I shouldn’t have to say “at least”
incomprehensible, thank you
Casually summarises digital electronics and even explains it better than some profs probably
Wonderful
Edit : yeah the approach in this video is a bit...inefficient
For those interested :
-The machines used to find the "smaller" and "bigger" number in adding are made of* half-adders (takes A+B and gives Sum and Carry). Hook em up as in the video and you get a full adder (takes A+B+Carry_in and outputs Sum and Carry_out). The full_adder can use fewer gates but redstone is already slow so I guess it doesn't hurt much.
-When making those "grids/tables" of outcomes from inputs , it is way quicker to find an efficient layout of gates by using "K-maps" which are also kinda fun to do when you learn them
15:02 if using brute force doesn't work, you'rn't using enough of it

Superbly done! The graphics are very clear and align perfectly with your descriptions. Your music selection is wonderful and it enhances the narrative.
This is so underrated. Computers are beautiful
this is incredible. somehow managed to barely understand everything bc u put it in a simple way and it makes you appreciate how much work goes into a simple calculation
You just made the best explanation of gates that I've ever seen. After so many years I finally get it. Hope the algorythm blesses this one.
First redstone minceraft video where I can understand logic gates. Loved the video and I'm grateful that you showed how to build the gates, a lot of videos don't show, and I find it amazing
I really appreciated the presentation of this video. The area I enjoyed the most was the fading away of your voice during complex explanations to only be caught up in regular volume during the finally or application of said explanation. I am by no means a programmer or a mathematician experienced in boolian agebra (sp), but this video made following along with complex topics fun. Thank you, keep up the good work.
Okay genuinely this is the best explanation of binary adder circuits I've ever watched. You've made something truly special with this video!
This is basically 9 weeks of introductory engineering class rolled up in less than 20 mins! 🎉🎉
I'd recommend watching mattbatwings' Logical Redstone Reloaded series as well. It goes much more in-depth with hands-on examples, and makes learning binary logic much more approachable.

I remember getting really into red stone creations when I was younger.

Any game that gives the theoretical possibility to build a logic gate, will eventually(if it stays popular enough), result in players building a computer. Building a MIPS processor in Minecraft was probably one of my favourite projects to date
Nice explanation of Logic Gates w/ minecraft.
Incredible video. This channel will blow up if you keep this kind of content up. Great job
This is literally the stuff we had to do in a course in first semester batchelors degree (computer science). More like a charter, because we ended up making a 8bit-PC. I love seeing all this again. But doing this on your own with the help of the script from the prof was a pain in the ass, when you didnt know what you were really doing
I’m a CS student and this reminds me of an electrical engineering course I took. You amazingly showed the uses of k-maps and so many fundamental topics!!! The elegant showing of the circuitry was so awesome!!! One of my favorite videos I’ve even seen.
11:05 So I don't know if you noticed when building it, but I realized that, since in order to build an AND gate you end up with a big NOT, and you then have to NOT it back in the XOR gate, you could theoretically just. Remove both the NOT gates for a slightly more efficient result.
that wouldnt work it would change the result
@@bigboland6160 Girl no it wouldn't. Two NOT gates in a row are equivalent to no gates
he also could use 2 XOR gates. "A XOR (B XOR C)"
This would've been such a great introduction to K-maps and boolean logic when i was doing electrical engineering in college! Well done!
....I'm having a war flashback to when I had to draw a big gate circuit for the seven segment
I loved how you used redstone lamps to show the signal traveling through the wires
Oof, this is definitely way smarter than what I did lmao
I had a bunch of AND gates that literally produced all of the possible decimals as separate redstone lines. Made the 7 segment section simpler cause you can just place torches in a specific order manually for each possible output, but is ultimately unsustainable if you want to add anything bigger than 9 + 9.
I mean not really? it *sounds* like you used a ROM which would definitely be the more efficient method. Seeing as you built a calculator already and by your own wording, im gonna go ahead and assume you know what a rom is. Ive build a few computers before and in most scenarios regarding 7 segment displays, a rom is perfect. Using traditional binary operations is soooooooo much slower and way larger for (and i can not stress this enough) THIS SPECIFIC GOAL. Roms have a tendency to get big quick when you add more inputs and need more outputs which dramatically slows down speed.
Regarding the limited output amount, ive noticed that the best way to go about it is to do the conversions sequentially. just map the locations you want the redstone to arrive at, make a simple counter, and only let the the data travel to the display with the corresponding count (i.e. if the counter is at 6, input the data to 7 segment display number 6). Then just slap an RS Nor latch before every single segment of the 7 segment display and have the display reset when a new calculation is processed.
Note that the girl in the video used a BCD converter in their calculator to use multiple decimal values. If you want to do this as well, you're gonna have to do it too. Im not gonna try and explain how but there are many guides online.
I wish you best of luck in improving your calculator!
Nah, the rom decoder method for 7 segment decoder is much more efficient than the presented logic gate trees. What you did was faster for single digits. And for multiple digits in decimal logic you just want to do binary coded decimal, then you can just reuse that decoder for each 4 bits.
Pugh. Torches? Use redstone lamps!
As a CS student, this legit has become one of my favorite videos
There's a bit of an error around 7:15 - the order of the columns in the Karnaugh map is wrong. The columns and rows are supposed to be ordered with Grey codes, which is to say that only one bit should flip between adjacent columns or rows, which means you can't have 00 and 11 beside each other. A good order would be 00 01 11 10.
In this particular instance, it doesn't make much of a difference, but getting it wrong can lead to suboptimal groupings.
This is my first video by you I am seeing… I am now subscribed.
You give me ShoddyCast vibes, great work.
The script, the production value, the clarity! Gush gush, bow bow
this is some crazy nostalgia unlocked
That was an amazing video and the "OMG" at the end slammed me face first back into the tile floor of my highschool AP programming class when the schools antivirus incorrectly identified my C++ program for "life" as a virus and deleted it. My fault for not having a backup but still... Exact same "OMG"!!! Keep up the amazing productions!
7:21 Am I crazy or is this big logical statement just identical to A XOR (B XOR C) which is in turn equivalent to A XOR B XOR C?
You are not.
I also thought Karnaugh Maps were supposed to be indexed in gray code? I was always taught to label the columns as 00, 01, 11, 10.
@BetaDude40 I'm pretty sure it's grey code that is important and any sequence would work (for example 10 00 01 11). If that is true, using 00 01 11 10 specifically is not required, but probably used has it is the simplest way to convert a truth table into a k-map
You aren't, that is indeed just A xor B xor C, and that's also just how anyone would implement it. The later section offers also two different layouts for the xor gate funnily enough.
A xor B == (A or B) and not (A and B) == (A and not B) or (B and not A) == (A and not (A and B) or (B and not (A and B)) to just offer a few versions.
When using redstone logic, almost anyone would use the (A and not B) or (B and not A) variant for simple repeater torch logic. It has the lowest delay, and is generally more compact.
The 7-segment display logic gate layouts are also silly. Nobody lays those out as separate logic gate trees. You'd just use a 10x7 decoder array instead. It's significantly more compact, and that is what we all did even 10 years ago. Would've been much more interesting to see that concept explained.
@@CensoredUsername_ There was a brief flash of text at 16:18 that explained how a decoder would have been a better option but she wanted to only use gates for the sake of a more cohesive video
this video is just next level, very detailed and yet enjoyable just perfection
If you guys wanna learn more about doing that kinda stuff with redstone, I highly recommend mattbatwings' Logical Redstone Reloaded series. It starts with the basic stuff shown in this video and gets gradually more detailed and complex, but still pretty easy to follow, specially if you do some tests yourself alongside the videos.
Absolutely agree, check out the rest of his channel too if you’re interested!
Absolutely amazing video, love the presentation and the music. Perfectly fits just how insane computer science and logic boards can be lmao
technically there's not on/off for redstone, it's 0-15 level
Just like transistors aren't on/off but in various states of it. Depending on how robust they are build, you could make a 3 or more state calculation using them. But it is much easier, cheaper and more reliable to just use two.
Well, if I power a redstone lamp with a 15 signal, it turns on, but if I power a redstone lamp with a 1 singal... it still turns on. The truth is, both ways are hardcoded into minecraft, it's just that in most cases, binary (base 2) is just easier to use than hexadecimal (base 16*).

The fact that you completely skipped over the conversions between bcd and binary is genuinely the best part of this video. I now want to go back to fiddling with logic gates again. Thanks my friend. I will be cursing your name in a month
I feel like this video is more about how binary circuits work rather than minecraft redstone itself. Feels kinda overcomplicated, and a few unique features of redstone had been ignored because they didn't have an equivalent in real life. The 7 segment display part really got me questioning if this is really a redstone video or a circuit video. And the fact that not a single actual redstone was shown (only the 2d perspectives were shown) was kinda disappointing. Still though, this is some amazingly good editing. I love the parts where the lamps turn on and off on the path of the logic gates. That's a lot of explanations too, must have taken a long time to research all of that, very impressive.
Given the title of the video, making the content about how binary circuits work fits very well.
Plenty of content about how to implement all of the circuits discussed.
To be fair, there is a pretty significant divide between the computational and practical aspects of redstone. Just like how real life electronics are far more complicated than the computational logic they are driving, so too is redstone more multi-faceted than the circuits here. Minecraft redstone just happens to be a great educational analogue for computational circuitry and demonstrating how discrete math can be implemented. I imagine that for many redstone engineers, there is a difference in skill and knowledge between the "engineering" side making use of BUD power and zero-tick clocks, and the "computational" side scaling huge systems of logic to accomplish complex tasks.
Given that Minecraft redstone is both turing-complete and has so much depth in its underlying mechanics, everyone should know a little bit about both circuit logic and gameplay mechanics to optimize their builds. At the very least, redstone is a great educational tool
i think the point of this video isnt how the redstone works, and he does show you exactly how to make each one. making a computer in minecraft is like 99% working out the circuits and planning and 1% actually building it. all this information is necessary to understand how its possible

This is really cool (and I think electrical engineering), but an interesting potential crinkle is that while redstone components are often binary, but redstone itself is in hexadecimal and a lot of more recent redstone components support this.
Man puts so much expression and drama in a numbers 💀💀
I've always been fascinated by redstone computers - I never really got into redstone (despite being a programming nerd) so I didn't realize just how...theoretically simple this all is, if that makes sense? Not to say that this still isn't impressive! And dear gods if you asked me to make a redstone computer from scratch I don't think I'd be able to do it without a lot of time and TH-cam tutorials, but the way you lay it all out in this video is absolutely fantastic because the next step just feels glaringly obvious. I think that's an incredible feat for a technical video like this. Wonderful work

It pains me to see how unoptimized that adder is. The second half of the ones digit is literally just a second xor gate, but the video never gave an indication that that was the case. In addition, both the ones digit and twos digit had identical xor gated that don't seem to have been merged.
Technically, a decoder is just a bagillion gates. A BCD to 7-segment converter is 10 parallel 4-input AND gates, followed by 7 parallel 10-input OR gates. Unfortunately, propagation delay tends to be more important than the number of components, especially in redstone, so such a solution, while far more boring than the shown solution, is usually preferred.
That's a lot of effort to convert between decimal and binary, and programmers tend to be lazy, engineers tend to be cheapskates, and neither tends to be willing to put in that extra work to make those converters, and so will just leave things in binary, or if you're lucky they'll work in hexadecimal since it doesn't need full division in order to convert to and from binary.
Make it work, make it right, make it fast. Optimization comes when you have working system and does not really add to the overall approach. So not having that step isnt a big deal.
I could definitely imagine sitting a kid who likes minecraft down and having them watch this and follow along to help teach them all about basic boolean circuits!
