For what it’s worth, there were computers before transistors. So really what transistors did for us was to make the computer a more practical tool by virtue of being much smaller, less power hungry, and far more reliable in operation (e.g. no burning out vacuum tubes left and right, no need to constantly tune or tweaks parts to keep it operating correctly). - electromechanical relays -> vacuum tubes -> transistor with a lot of interest rabbit holes like magnetic logic/
++ I always wondered, if they're really a switch, then who turns it on or off, turned out a quartz clock ticking at some billion times a sec (GHz) is ignored or taken into account by some already encoded transistors/memory in BIOS chip, if there is no initial memory/information then transistor would do nothing, as you don't have anything to control them...
Manufacturers program a BIOS chip externally and then solder it in on the motherboard.
He's referring to the way how semiconductor devices revolutionized everything.
Before transistors, there were other devices which performed the same function as transistors and logic gates. I'm busy working on a series of online demos which show logic circuitry using relays and plugboards, because people can see their internals working.
Vaccum tubes were used before transistors
wasn't there a youtuber who made a vacuum tube computer a few years ago? I wonder how hot it will get.
This is deviously simple, I definitely see this as a kit being sold in the 70s to 90s. It's wonderful how useful this can be...
If so easy make it yourself then
I’ve done something similar. I studied engineering and the setup really is trivial but the craftsmanship is really good.
@@Ghost-xu4yg Well, op is talking about how simple it is, comparing to today’s or before’s standards.
@@Ghost-xu4yg pretty simple to make a lot off, i think if you make enough of them you could probably do it in a few minutes after a long time. "simple" to use and yeah compared to recent computers its pretty simple
@@nicky7006 It's easy when you are copying some else's process and models. Try to design it all yourself without any help 😉
I remember watching how you made it back then it really blew my mind especially when you created your own language it inspired me on my programming course
Thank you for staying a long time viewer, and wow I'm so happy to hear you were inspired!
@@3DSage Where can I find that video?

A Richard FeynmanIf quote comes to mind watching this: "If you cannot explain something in simple terms, you don't understand it. The best way to learn is to teach.
The ultimate test of your knowledge is your ability to convey it to another. "
I would say you pass that test, beautiful work.
Beautiful quotes that I agree with and thank you for saying that! :)
not very smart, as the understanding of things one man has, cannot be conditioned by the unwillingness of others to learn.
in fact, a person understands more than can ever teach, therefore the fact that that person failed to teach, is not real measure of what that person knows.
the real state of understanding is limited to the person only, has only sometimes to do with the teaching.
Feynman just something that is not really smart.
we can talk even more about understanding things, when we acknowledge knowledge is not only compared with some absolute refferencial, but it is also relative, meaning among people who know less, you don't need to know a lot, in order to know more than others.
again, Feynman not so smart.
Hey @@3DSage, can you make a schematic?
@@lucaspedro7272 I'm making a detailed video and update :)
Really like how it looks with the wood cases. Electronics inside wood is really vintage and nice looking
I'd like to use more wood stained 3D printed filament! I want to see that more often.
I like how your code actually sets the control lines directly, instead of running through microcode. It makes it far simpler and, honestly, pretty fun!
Man please oh please go into a deep dive series about this. This is really awesome and one of the coolest projects I've seen in awhile.
Dude this content is way too good. Everything here is extremely well executed. You deserve a million subs and a great YT career.
That's truly impressive. Great job at sticking with it despite obstacles and bugs.
I built the exact same computer in a school project. Same components but I didn’t have a 3D printer back then so the case was wooden and I had everything on a single PCB except the clock. For manufacturing the PCB I used a CNC machine which removed copper around the traces and bored the component holes. I loved that project. Learned so much
Stumble upon this today. This is so cool! One thing is to learn the technical stuff, but your build looks awesome as well. I love the modular design and bus expansion slots. Well done! Subbed!
This video was super useful in my current development of an 8 bit computer😊 When I watched this it helped me understand computers more and how I might design it!❤ And always remember, credit goes to where credit is needed😊
What an impressive amount of knowledge compressed into one short video!
The packaging is so elegant it became my new transition goals.
That's the best explanation I have ever seen, I have been searching videos like this for years, finally found it!
4:00 10101 = 21, 10000 = 16 for anyone that is wondering. But this computer is sick!
You can count binary on your fingers, using each of your digits as a binary digit, carrying to the next finger just as the flip boards at that timestamp. Expressing 4 this way is flipping the bird but you can do it in front of anybody comfortably if they're aware the context is counting to 4.
That’s a 5 digit so every digit that’s 0 doesn’t get added and every 1 does. Reading it from right to left so it goes like 2, 4, 8, 16, 32.. and so on. Every digit gets multiple to the power of two starting from 1 (1^2) because we have 2 selections for every switch “on” and “off”. So 10101 would be 1+4+16=21

@@nko3210Huh I never knew that, Thank you😊
Wow! Cold not say anything but "Wow!" You really take all path from zero point!
This is phenomenal! I love that you cared enough to create the beautiful wooden cases.
Very nice build!
I love its simplicity, the switches and its modularity!
Do you have future plans for this project?
If you're looking for a newer SRAM, easy to find and affordable, you may want to check the AS6C1008, it'll give you 128KB x 8-bit, it's still manufactured in DIP and it's much faster than the one you're using (less than 100ns access time)😉
0:09 almost thought it was a rick roll
lol
this is very inspiring, making a computer is intimidating but watching these steps make it seem a bit more approachable and less intimidating.
that's INCREDIBLY cool!! I've wanted to build something similar for years!!
Man, what an insane project, you really made me loving computers even more
Now the real question... can you make it run Doom?
LOL
Holy smokes, the clarity of your teaching and demos is extremely commendable!!
That makes me very happy to hear!
at its core circutry is so simple i love it that you can do anything that you set out to do based on circuits and logic gates
this is really impressive skills and very creative too
Thank you so much 😀
This really looks awesome. Do you have any schematics, drawings, notes you'd mind to share?
I would also love to see them if possible
i want too
I fucking love you, this is the first real informational video I have seen in a long time.
I mean as in, most videos like this, disguise themselves to be informational.
This guy there is the Mike Ross of Electrical and Computer Engineering, man thats really stunning to be able to understand all these concepts at your own !
Hopefully I'm not the only one who's said this, but you should definitely make and sell kits of these demonstrations, I would absolutely buy
I would too
Wow! That takes me back almost 40 years :D Very impressed with what you'd done there
I'm glad to hear that and thanks for the comment!
Saw this today. Brings back memories of a arcade controller I built using the 555 timer, a pair of 74ls193 counters and an eprom. It converted an arcade that uses a trackball into a joystick.
But yours is a super cool project.
Good show.
You are absolutely brilliant!! Well done on this and you inspired me as well to study more Transistors :)

You are a genius that shows people they can achieve so much just by putting in the effort. I made a game based on your raycaster engine, is it okay if I mention you in the video?
Thank you! Yes of course you can! Let me know if I can share your link on twitter and Instagram.
@@3DSage of course! I made a video of the game and later I’ll make a video of the process :)
I am so amazed by this! It's great. I made me do some electronics again!
This would be a really cool hands on way to learn computer engineering and understand how it all works together! If I was taking a CS class or computer Eng class, I would LOVE to learn this way!
Great! Now make it run doom
I need more ram but maybe... 😎
🤣🤣🤣🤣
great explanation! Also, the binary number was...
21
(1 * 16) + (0 * 8) + (1 * 4) + (0 * 2) + (1 * 1) = 16 + 4 + 1 = 21
I was looking for someone that commented it.
it's also 9+10, cause 9+10=21 ;]
Woah this needs to be a kit and a book for kids to learn 😅 I'd buy a few for sure 😊
this is my first time in this channel and i will subscribe because you explain everything nicely, keep up the great work!!
Is there a schematic for this?
I would like to build it...
It's a bit of a stretch to call this a computer with it being basically a counter and a RAM IC.
But there's genius in how much use you managed to get out of them!
your explanations were so good, you made working with that little thing sound easy
Thank you for this inspirational build. I'm looking for a simple and portable DIY computer design. I like your design being modular. I hope I can build my own soon.
School computers in a nutshell
now make it run doom
its impossible to do that game on 4 bit computer
This is the first video I have seen in your channel just now and I instantly liked and subscribed!! I wish I have seen your channel earlier :D Keep up the great work

Nice and simple design. Thanks for sharing that design!
This channel is a real gem
This is the coolest thing I think I've ever seen, I want to make one myself now
This is awesome! Well done. Showed it to my CompSci students.
You have the brain of a designer. I'm impressed.
I just want to say good job. It takes a lot of work to do something like this. Bravo sir.
Thank you very much!
Cool video, I really love this kind of projects and yours look awesome.
Just wanted to point out a transistor is very fast, but it's not even near the speed of light. They have a switching speed, which is defined by it's capacitance and it's shape (size) and it's measured in frequency. If you check the transistor datasheet you'll find the gate delay and it's probably going to have a formula. Also, the wire's in a circuit are not perfect conductors and they have resistance, which makes the electricity move at around 1/3 the speed of light. It's still pretty fast, but not speed of light fast.
I love this, keep doing this
perfect !!! this is one of the great article i was looking for... this is GREAT and very nice ... salute you 3DSAGE... cheers !!!
Exactly what I needed and was looking for! Thanks!!
You are welcome! :)
Very nice! I love the physical design. Can't help thinking, it wouldn't have taken much more effort to make it Turing Complete. Future project..?
Amazing Project !
The video deserves 1M+ views and you deserve to be a big RUclipsr. Can you add a multiplier on top on an adder for faster math?
This was a nice video to watch. :)
This computer reminds me of a simplified version of Ben Eater’s breadboard computer.
So this was a really cool video. I built something similar but it’s only 4-bits wide. I’m interested in the guts of your CPU. What are you using for an ALU and what are you using for the the instruction decoder; are you using microcode to decode or are you using a demultiplexer and gates? My Clock, RAM and address register is pretty much identical to yours.
Really cool project and video. The reversed MSB and LSB order is killing me though lol
Really good project and explanation!
Congratulations
I don’t think I’ll be building my own but I wanted to tell you that the graphic on how the transistor works was an eye opener for me. I’ve read and watched many explanations but that little clip told the story in an instant. So thanks for that. Your machine is cool and I admire anyone who starts from scratch and learns the skills as he goes. It’s like teaching yourself to weld two plates together and then proceeding to build a car. Good job! 🥸👍✅
As someone who has been studying electronics and how to test, repair, and assemble them, this is really cool.
Thank you so much for saying that! :)
that insane, nice job
i absolutely love this project, very well done
and using wood for the casings gives it such a vintage and cool look, this is something i would love to have even if it's only for display
im not gonna lie ur a hero like me i dont have a ged but i had to self teach everything i know but to make your own computer thats insane
I really like that binary flip counter. Going to turn one into a clock.
This is 100% on my bucket list.
ok this is super cool i always come back to this video when im bored and every time i get motivated to make a new project using transistors its so much fun watching this computer do what it deos best and seeing hil explaine everything perfectly
Wow that's a wonderful thing to hear! I'm glad you get motivated and I say use it and have fun making your own project! Go for it!
@@3DSagei have a question do you have plans on making a video about all the details i weuld watch every nanosecond of it
@@3DSagewhat ic chips did you use to do the opcode thing
Man I love that digit flipper
I do need one on my desk
Epic! Thank you for sharing this with the world
Thank you for saying that! :)
Hol' Up! I wanna know more about the Etch and Sketch part! That's sick!
You just made me understand and or and not gates in the most simple way possible
Nice woodworking. It does not matter so much if a computer is unable to count higher than sixteen or something, as long as it looks smart.
Great project!, if you add an ALU it can be able to make simple calculations
I really love this and i wanna learn how to build one
Did you forget the exclusive or gate its used as a decoder so for example the alarm clock matches the time when it knows to beep.
Closing that latch on the outro was sick
Case closed. Literally :)
This is awesome. What a great idea I still don’t understand it. I would need to sit with you and ask if you questions but I don’t understand how ones and zeros can do anything but I do get that what you doing can visualize it and I’m a visual learner, so thank you for doing this.
I hope you learned even a little bit or have a better understanding. Storing several 0,1 create larger numbers which can be used as addresses in memory or values. Computers are really just glorified calculators. I hope you enjoyed the video!
Btw you do a great job explaining this and connecting the dots.
BROOO THANK YOU!!!!!!!!!!!!!!!!! YOU'R THE BEST!!!!!! I LEARNED EVERYTNice tutorialNG I NEEDED TO KNOW THAN YOU VERY
Do you the schematic of the computer, i really wanted to build it for myself. I really liked your computer and loved the work you put in this
Hey! great video, I love the computer, I love the style and how you did everything, I was wondering what components, schematics, etc you used. I've always wanted to make a ~4bit computers but i don't know how to put them all together ect, do you use 9v? or 5v. anyways I think thats all and the answer to the binary question it 21
i am going to start a similar project now! Thanks!
I'm happy to hear that! :)
These Red/Green/Blue circuit-boards, feels like the beginning development of the "isolinear chips" in Star Trek, that allows them to swap out modules of the computer to do other things that are pre-programmed into the chips.
(it also feels like modern circuit-boards, like graphics cards & ram cards, but that's not as cool) ;P
Damn, that's really impressive!
