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!

As someone who love Ben's videos. This is awesome!

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.

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!

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.

i laughed at "when i go to college" bud this was more ambitious than half the projects i did in college

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.

Fantastic video. I am new to computer science and this type of project is very inspirational and exciting! I am looking forward to part 2!

Ben Eater's series is great! After years of trying to learn computer architechture, it finally clicked when I watched Ben's series.

Looking forward to watching this develop

Excellent video/series, man. Very well explained and technical (in a good way)

This is the best Video I have ever seen mentioning how computers work ❤❤

Thanks for the motivation. I wasn't sure if I could do it, but I might try it eventually.

really amazing project! :)

Wow! These guys have so much time. It was entertaining to listen to this dude. First few minutes ;)

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!!

Great stuff. Just saw your post at reddit. Hopefully this channel will get the attention it deserves soon! :)

We done, and we’ll written. Looks forward to further episodes. Best success!

Simply impressive! 👍

Very interesting (simple and effective) architecture. Have to implement it on my simulator.

Aah Yes I Love These Videos..... Ben Eater and Yours Channel is what I look forward to Keep going with your content!!

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.)

"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!

no joke, I've thought about Tetris on transistors before. Awesome video, thanks

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.

What fantastic work! I've dreamed of doing this, but never have done so. Great work.

Young man, you are going to go far in life. Keep it up.

You get the best intellectual men who never went to formal education yet they made the best

THIS IS SO WELL DONE

Awesome project!

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 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.

really great project and the video is really well delivered! congrats.

16:15 and 16:50: A memory map so nice, you announced it twice! :)

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.

phenomenal. thank you

16:00 the code does work if you put `index` in RAM, `index` is just a regular variable

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.

Very good brother i like your channel

Lev, great video!!

excellent video

Bro was staring in my soul at the beginning 🥶 ( great video )

this is so awesome after watching ben's videos

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.

Cool video, thanks :)

Congratulations! I am also working on a homemade 32 bit computer.

Certified awesome. 😎

very impressive

Nice, like full 😉👍👏👏👏

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?

Amazing!

I don't understand a single word he is saying but this is still on of the most entertaining youtube videos I've seen

Thanks for tutorial

0this my first time in this channel. 0:26 sec in and im ALL IN HERE

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.

I was actually thinking about transistor style login in Minecraft TODAY! I love Ben Eater’s videos, would you be interested in doing a video on your Minecraft version/sharing the world? That would be an excellent starting point, having seen Ben’s videos

Pretty cool

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?

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.

very very cool

Hell ya...i am gonna subscribe.

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.

Awesome

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...

Thanks Lev

I think I never subscribed that fast to a channel

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)

well this is awesome

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)

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.

Ben Eater Jr. 🤩❤️🔥

Do you have a part list so we can buy and follow along.

Seems similar to the “IntCode” implementation from the 2019 Advent of Code problems

عمل رائع حياك الله

This great !! my question is how did you learn all this ?

What transistors did you use?

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

Hi! What books did you use to learn all that? Me want.

next video creating a two cpu motherboard homemade, do you think its possible?

How are those yellow relay? Are they reliable?

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?

WTF! teach me all of this! subscribed

Are there good KZfaq 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.

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.

which transistors are good for building a computer

hello, are you going to continue this series?

“When I go to college” this is an insane project for a high schooler

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.

Congratulations! You have re-invented 6502.

wow

Awesome😱😱😱😅

nice tutorial for young guy

good

Doesnt understood anything but it felt nice

Занялся таким-же проектом, но решил использовать 74hc... для начала (4 бит), а выше уже хочу использовать FPGA Чистые транзисторы, это уже слишком для меня😂 Слишком много проводов и соединений

👍

I’m overwheld it’s soooo much

Hey there Lev, what subject are you going to pursue in college?

Don't forget to add sound!
