Lev - at the expense of being long winded - here it goes. I found this video today. My face quickly grew a smile. I'm quite old by today's IT standards. Started out building a small micro computer in the 70's as a teenager. Grew up professionally in the mainframe space. Eventually made my way into client server and other related fields of IT. You might say full circle on many fronts. I have often feared that today's younger generation is missing out in understanding the low level world of computers. I myself have dealt with IT professionals today that do not even know what a CPU register is - yet they 'program'. I bought Ben Eater's kit in 2019, built it, brought out the old computer from the 70's got that running and I'm back in the game again with low level computing. Can't get enough of it. This brings me to your video and work. I can't express how happy I am to see that a young person (by my standard of age) is interested in this level of computing. I know from Ben Eater's Reddit that a lot of people are working on it, but I never really understood what the demographic spread of age was involved. I think it it AWESOME to see you getting into this low level stuff. If you don't already know, as a seasoned IT professional, this will open huge doors for you. Thank you so much and I look forward to watching your progress!
that's why I'm here. I'm a programmer and so many I work with are comfortable just doing that, I need to go to the deepest level, I have to understand this stuff from A-Z, makes the job a lot easier too lol.
I am 25 and really want to find time for these stuffs. My grandfather collected mechanical calculators, and I really want to know more about the early days of transistor and computer technology. Will probably buy a Ben Eaters kit, seems funnier and more productive than lego. I was the last class at uni to get tought these lowlevel stuff, the supervisor knew nothing and everything was stressed, really want to emerge and take my time to understand... Also to be able to teach my nephews and niece. And possibly other kids that want to listen to me when I turn 40 and speak about "the old days" that actually was 30 years before my birth XD
I fall somewhere between the computing OGs and the iphone zoomers. I grew up with dial up modems and AOL. In any case, I love to see young people getting in the trenches with this low level close to the hardware level of development. It's knowledge that needs to be retained. You will be changing the world by the time you are my age!
I built a 1 bit adder using discrete npn bjts. It took an entire weekend and was very hard for me. I am much older than you are also. This is all to say…. What you have done is just simply extraordinary.
Very impressive that you learned this on your self. I got to learn these basics in my CS bachelor. Was fun and tedious and frustrating. But magical too. No simple feat to understand it, but even more impressive that you learned it yourself.
When I was an intern, working at a steel foundry, the computer that ran one of the furnaces was almost all based on discreet NOR gates. I made hundreds of those boards to keep as spare parts.
It's a bit dated but it's still great source material and the ideas and concepts are still quite relevant... There's a university channel that gets into ISA design - CPU Architecture and System Management... I think the later courses extend on this and even get into Operating System Design. I believe the University I seen before is called Bilkent Online Courses. Now they have a lot of courses for many different topics in software engineering, but there is some hardware engineering related material. I think the courses I watched was from around 2008 - 2012 era... It's really good source material. And the one professor explains things quite well.
What a fantastic and inspiring video. I have a ph.d. In an unrelated field and am a tenured professor, yet you make it all so elegant! Really enjoyed video 2 as well. Congratulations and keep it up!!
Very nice work. I am late to the party. I have been programming professionally since 1999. I am of that generation that had to know a little bit about how computers worked to write programs for them. And I have always tried to instill that into developers that I teach. It is pretty impressive that you would take that on yourself.
This is great engineering. I started on C64 and 6510 assembly, and you designing all that ftom scratch means you have studied and learned all the fundamentals of it. It's a pitty you stopped making more videos on similar topics.
understanding the hardware is interesting but more interesting is how the different manufactures came togather to decide on specification standards. The evolution of architechtures, standards, specifications, apis is really interesting to know as those human decisions are key to understand how modern complex systems flawlessly works with themselves.
I think about that too, but more in terms of competition fallout. Surely over the decades some people got burned and left out of the industry as their standard was suddenly made obsolete. I can't even guess the politics and plays that the big companies made to ensure their survival.
Came together to set standards? As I recall they just all write their own standards, and whoever wins the most market share gets to tax everyone else for the IP, or at least tax everyone who wants to sell anything compatible. It’s the American way.
"I have no formal education in electrical engineering." -> Awesome, that - by my experience - correlates with good content. After watching the video, I would say that hypothesis proved itself to be true in your case as well. Good job!
I was also infected by the Ben Eater series :) If i was to do it again I would like to try and feed my architecture into chat gpt. I think it could really speed up dev in a few areas. Your full transistor design is impressive. Fun stuff. You, like Ben are building a floor for people to stand on. Thankyou.
I understand electronics and programing (including basic assembly) but in between those I find incredibly hard to understand (same like chemistry, it's just black magic), I have a lot of admiration for those who do. It all goes to show we all have a place in this world and that we are not all equal and the differences are what make the world go round. I am quite happy to not know how the screen is drawn while I type an Email to my friend about a funny cat video I saw the internet. Respect those who have gone before but realise they didn't know everything and there may be a better way of doing things. So long as we all move forward together we can't fail. Sorry for the rant, I have been drinking tonight.
I'll say this much, as a student going to one of the top universities in the country as an Electrical Engineering student, especially learning as much in theory and concept about these components such as transistors or microprocessors I've learned just as much if not more in the first 45 seconds of this video than you could learn at a top tier university. Sad but true.
Please by all means, learn as much as you can from the internet before wasting your money on a degree unless you absolutely need it. It's all a scam. please.
I like your ideas. Your commands are very reminiscent of the 6502, but that's an awesome chip so my comment is not a criticism. I was planning to build a *really* basic computer after watching Ben Eater's breadboard computer videos, mine would have a total memory of 256 bytes, with an ability to modify to stack size against free memory to give maximum convenience, depending on the program being designed. It is only a demonstration computer. When I get around to it. (Just need a decent lockdown to give me some time.)
Very nice work! I have been thinking of a design for a 12-bit Addr / Data computer. It was hard, but I was able to decide on a 16-instruction set. That's 4-bits for the opcode, and 8 bits for data all in the instruction. Originally, the plan was using relays, but I may end up going with transistors like you. This is very interesting stuff! All good wishes.
I feel like 4 registers isn't enough. Especially because they are special purpose registers. Less memory accesses are needed in a CPU with more registers. In the few cpus I've built, I usually use 8 general purpose registers, convinced with the numerous special purpose registers. In programs like Tetris, this allows the cpu to not access memory as much; more data can be stored with the alu. One register for current falling brick x position, another for y position. The next for the current block type, and the fourth register for the next block type. things like these allow you to do constant operations on these operands very quickly without having to access memory (takes multiple cycles)
I definitely hope I can do something similar to this before I graduate. Having university resources will most definitely make such a process easier. It's more of the programming that I would struggle with because I'm not the most familiar with that stuff atm. Plus there's no gdb or valgrind when you're building your own cpu.
brother , it would be great if you do a video on how you have started out in thus HOW THE COMPUTER WORKS and BUILDING ONE ON MY OWN journey , what books you've read , whom you've watched , how long it took , your advice for novice people like me and also what mistakes not to make . please say what u think , I'm waiting for your response...
Nowadays it is, back in the 80s and 90s the computer "nerds" did stuff like this but with less access to information unfortunately. They got it nice nowadays.
Have you checked out Usagi Electric's Vacuum Tube Computer project? It might be interesting to compare to your own goal (though the technologies are a bit different)
2:37 I like the clever idea of reducing the number of required registers to keep the transistor count to a minimum, even if it means needing to tweak the code a bit to accommodate. I'm wondering if you might still be able to drive those 2N7002s at something like 1 - 10 mA because 200 mA seems ridiculously high. Have you tried that already?
There seems to be a rather hard lower limit for the number of registers to still be able to implement 8086 microcode. We need PC. We need a stack to push away context. For MUL and REP we need CX to count. We need AX, DX for the values. For MOVS we need two addresses, let’s store them in BX and DX. On 6502 CX would be X. Y and Z would be the addresses is MOVS . DX would be B.
I think you could have talked a bit slower, I feel that as someone who's here for the pleasure of it, your presentation was about twice the speed it needed to be lol. For me, the length of the video doesn't matter a long as the contents good, and if the contents good I'll keeping watching whatever the length. Keep up the good work!
@@levkruglyak you have to decide whether or not you're an educational channel or just wanting to show your work to others who might already understand most of it
@@levkruglyak As someone whose first language is not English, I can tell you this was fast talk indeed. I'm used enough to understand all that you said, but most of English-foreigner viewers will not. Even native English-speakers would also need some seconds to let technical concepts sink in before the next one is up. That all would slow down your videos, but that's the kind of patience you'll have to allow yourself in order to get more viewers.

So, when you're performing the JSR, are you pushing both the high and low bytes (8 bits) to the stack to get a full return address, or are you shortcutting it to within 256 bytes of the subroutine and just applying an offset?

2:41: I don't think something a little over a kilowatt of power is technically _unfeasible._ Electric kettles routinely exceed that. Even in the U.S., anything up to 1.7kW should be okay. Admittedly, it still might not be _preferable,_ and might make your air con and electricity bill scream for mercy.

You can speed up the turn off time of a transistor by discharging the the capacitance in the base to collector junction by using a germanium diode.

Thank you! Here's a request from ! Can you please make a tutorial on how to record your actual tutorial and input your own soft
I found out why soft softs so different compared to Ableton. It is because there is a default limiter on the master that i didn't know about.
I know it seems kind of anachronistic to study retro-computing as a young person, but I don't know how else you can learn about how computers actually work. I don't think it's possible to study a modern processor in depth like you can with a 6502 or similar.
Pretty cool
Hi Lev;
Which country are you a citizen of and what is your education on the subject?
Drag the volu for the setuper track that you're recording into all the way down.
Awesome
Do you have a part list so we can buy and follow along.
Doesnt understood anything but it felt nice
What transistors did you use?

Thanks for tutorial
phenomenal. thank you
Are there good UA-cam videos/Playlists I could study from to able to build similar stuff, also what are the topics I need to study to build similar things.
So, when you're performing the JSR, are you pushing both the high and low bytes (8 bits) to the stack to get a full return address, or are you shortcutting it to within 256 bytes of the subroutine and just applying an offset?
the stack is 16 bits wide, only the stack counter is 8 bits
Do you have a logic analyzer say 64 channels ? I would be awesome to watch this in action. The fetching of opcodes and associate data. The result of an addiction instruction and so many things. I work with microcontrollers which is very similar in nature. I lately have been research a older Zilog Z8 series mpu which came out shortly after I graduated from Devry. I'm using a Z8613RS and a Z8681 in expanded mode. It's a lot of fun. I think that's awesome building a computer from discrete transistor. I just want to say Hi and wish you well.
I’m overwheld it’s soooo much
nice tutorial for young guy
Are the 16bit instructions just literal control words? If so, do you break them up into more than one step in the instruction decoder logic?
very very cool
next video creating a two cpu motherboard homemade, do you think its possible?
Hey there Lev, what subject are you going to pursue in college?
WTF! teach me all of this! subscribed
i also want
I was born back in the day of C64; I would sometimes hack my mum's C64 as a young child.
which transistors are good for building a computer
FETs. You can use bipolars but they will consume more power and you will need more of them.
How are those yellow relay?
Are they reliable?
well this is awesome
