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 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
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.
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😊
Great briefing explanation. My son started taking electronics classes in high school, and i'm and arcade tech/collector for the past 30 years. I've recently been expanding my own knowledge on electronics history and science of it all. I mainly collect classic arcades which use "old tech" components wise. I also picked up a 50s era TV and a radio with vacuum tubes. Just fascinating. Definitely subbed and gonna show him this. Somehow, even at my age, I can somewhat comprehend a lot of this.
Edit: BOOM, it just hit me. at the 2:25 mark. I watched this over and over and NOW i get the GATES. It was the locked status NOT GATE that was throwing me on how MEMORY worked. THANK YOU
I'm so happy I could help! Thank you for the very kind comment! :)
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
That's truly impressive. Great job at sticking with it despite obstacles and bugs.
Dude this content is way too good. Everything here is extremely well executed. You deserve a million subs and a great YT career.
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😊
Woah this needs to be a kit and a book for kids to learn 😅 I'd buy a few for sure 😊
Holy smokes, the clarity of your teaching and demos is extremely commendable!!
That makes me very happy to hear!
Wow! Cold not say anything but "Wow!" You really take all path from zero point!
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
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 ;]
this is really impressive skills and very creative too
Thank you 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!
That's the best explanation I have ever seen, I have been searching videos like this for years, finally found it!
Great! Now make it run doom
I need more ram but maybe... 😎
🤣🤣🤣🤣
No it cannot run doom. For doom you would need a real pixel display. And his computer does not have that. Oh, and also, the controller does not have enough buttons to controll doom.
Also x2, the computer does not have enough power to run doom. It also cannot do basic operations like adding, subtracting, multiplying and subtracting. Its only a little project designed to do really simple operations.
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! :)
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
The packaging is so elegant it became my new transition goals.
Now the real question... can you make it run Doom?
LOL
What an impressive amount of knowledge compressed into one short video!
Could you please make seperate videos explaining each part of your computer for people who want to make their own
I have had a few requests for this so it's something I would like to do :)
@@3DSage thanks =D
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 :)
this is very inspiring, making a computer is intimidating but watching these steps make it seem a bit more approachable and less intimidating.
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)😉
Going from zero electronics knowledge to this is pretty impressive. Very clean looking design and a nice implementation of the electronics. The case and presentation are first class as well. However, and I don't want to be negative, but I can't really see calling it a computer, part of a computer, yes. A computer would have two more things needed, one, the ability to compute (i.e. Add two numbers) and two, it would need to be able to make decisions (i.e. compare two numbers) and branch accordingly. I would call this a programmable state machine. I still is pretty impressive and just plain cool looking. I am for anything that promotes learning in electronics, so a thumbs up.
Exactly, glad someone said it. It's a kind of "sequencer", does not really process any data, nor it has any ALU. I'm wondering how he's using all those peripherals with it.
yes. and it must be inside a chip which can understand halt,reset,jump,input commands
Is there a schematic for this?
I would like to build it...
Closing that latch on the outro was sick
Case closed. Literally :)
Man, what an insane project, you really made me loving computers even more
Wow, I want to build my own diy computer some day. This is very inspiring!
SAME
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!
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 comment is no longer strange a year later 😅😂
Made out of previous girlfriends
basically grooming
@@jaberjansabe1539 personal experience?
@@nxmx6ix mate im 18 💀
This is phenomenal! I love that you cared enough to create the beautiful wooden cases.
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!
i am going to start a similar project now! Thanks!
I'm happy to hear that! :)
School computers in a nutshell
You have the brain of a designer. I'm impressed.
now make it run doom
its impossible to do that game on 4 bit computer
This was my childhood dream to craft a pc myself
arduino has been invented
The main intent is learn
Not make

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 !
I just want to say good job. It takes a lot of work to do something like this. Bravo sir.
Thank you very much!
You just made me understand and or and not gates in the most simple way possible
that's INCREDIBLY cool!! I've wanted to build something similar for years!!
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.
"can i make my own motherboard from scratch" landed me a gold mine
3:00 he just did the minecraft clock trick thing
You made a whole computer system nice
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.
I always wanted to build my own computer, now im sure its possible
You should! :)
What a journey you have had! Fair winds sir!
I’ve become very interested in computers myself lately despite having no real prior experience or education in them. Wish me luck friend
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
Reading this made my day! Thank you for saying that and for the support! :)
I didn’t understand a word of this but it’s still fascinating
Wow... as basic as it is, it still seems useful.
Great project!, if you add an ALU it can be able to make simple calculations
ah hell naw my man's got the etch-a-sketch peripheral
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!
Dude... your computer is so so good that im gonna copy it in a video game using only logic gates. Hope your okay with that😊
Yeah.... its hard to copy.
What is the game ?
@@zerkuya9540the name of the game is "evertech sandbox". If u want to play on PC, then download another game called "scrap mechanic". The first game is a mobile version of the second game. Scrap mechanic is better, because there are more, WAY MORE YT tutorials. Also, these games were designed to make vehicles. But, they added logic gates, so that's why I use it. So, Scrap mechanic users have YT to work with, but I'm just on my own. Hope this helps!
You are absolutely brilliant!! Well done on this and you inspired me as well to study more Transistors :)
I must do this project some time in my lifetime
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
And i found the top 5 fav channells, im so lucky!!!
Wow that is very kind of you to say so thank you!! :)
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
This video taught me abt redstone transistors
I'm glad to hear that! :)
@@3DSage tust me,i am too
(for 4 years ive been playing minecraft and coulnt understand any explanation of transistors)
21 was the value of that binary number 10101. I stopped counting the normal way with my fingers. I now count on my fingers using binary. Usually, I use my pinky finger for the first place, ring finger for 2s, middle for 4s, index for 8, and finally the thumb for 16. I've been known for wasting time by counting to 1023 on the 10 digits of my hands. After a while, certain patterns tend to stand out. Some funny, some surprising. 800 was a rather confusing and surprising number using your hands. You almost don't believe how perfectly round that number is on your hands.
My apologies for acting like a silly nerd on something so mind-numbing.
0:14 - 0:15
Isn’t that kept the scientist and inventors of old going?
I mean a lot of them became obsessed until eventually succeeding at what they do best imagining theorising and creating
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.
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
Thats cool! I have been thinking of doing the same project.
I hope you make and post your project too!
I really like that binary flip counter. Going to turn one into a clock.
You should add to your computer math and make it more powerful. like playing pong on a led matrix for example .
your explanations were so good, you made working with that little thing sound easy
Your computer is really beautiful
Thank you! I think so too :)
A saying I have adopted recently: a complicated thing is just a bunch of simple things in a trench coat.
I'm sorry.... I immedietally got hung up on the whole consept of 3d printed WOOOOOOD?????
Yes it's real! Real wood fibers mixed with some other materials and pla filament but it smells like wood, sands and wood stains like wood!
I think this may be the simplest and best DIY computer on the internet
2:05 "Functions at near the speed of light" is basically meaningless in this context. Yes, electric signals travel near the speed of light on a circuit board, but that is entirely independent of how fast a transistor is. Most discrete transistors are quite slow, actually. They have a certain amount of capacitance between their terminals that takes some time to "charge up". (very simplified explanation)
This is beautiful.
Memory recalls of the Altair 8800. Thank you.
Amazing Project !
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
This computer reminded me of the Enigma machine for some reason
Can you public schematics plese?
So he basically made a toy PDP8. 😎
that insane, nice job
Another brillant person on the interweb
Love the binary odometer
this is my first time in this channel and i will subscribe because you explain everything nicely, keep up the great work!!
I feel like we're finally at the point where the internet has refined its information communication so well that people who aren't trained in electronics or computers are fascinated by low level stuff while people fascinated by electronics and computers, who have access to universities and advanced books are studying to be front end developers.
Like, cool. You can code in JS and harvest user data. but can you make a breadboard computer like 3DSage or Ben Eater?
Neatest computer i've ever seen without any cpu, so cool!
I love this, keep doing this
