Hey everyone, I want to give a quick update on the computer series as well as tell you about something else I’ve been working on so if you’re interested in what’s next for my youtube channel then stay tuned So first off with the computer series, I’m still planning a couple more videos before I call that project done You know my goal is to get to a point where the computer is turing-complete So so that is to say that in principle that can do anything that any computer can do obviously it’s all going to be limited by the amount of memory and clock speed and things like that but But but I think by adding one more instruction to to the computer to do conditional jumps sort of you know if then logic That should make it you know turning equivalent to what most people would consider a real computer So I think that’s maybe going to be one or two more videos, and I’m actually working on the next video today I’m not sure exactly when it’ll get out there. I’ve got some travel coming up so I’m not sure when it’ll wrap up, but but it is it is on its way But in other news I started a podcast The podcast is with two very thoughtful people who like me are interested in education We talk about education and other things on the podcast so one of my co-hosts also named Ben is a Was a classroom math teacher for several years, and now he’s doing a PhD at Stanford focused on education and data science My other co-host grant runs the YouTube channel three blue one Brown Which if you don’t know about that you are in for a treat. He does just absolutely phenomenal explanations of You know complex ideas from from math and a few other areas, so I’ll put some links to that down below But the podcast is called Ben Ben and blue And there’s already a few episodes out there so in the latest episode which is episode number six my co-hosts Put a question to me that you might be wondering which is what’s next for my YouTube channel So just to give you a sense of the podcast here’s a clip from that episode you see this right here like this is one of the big values of I think you as a person and especially you as a Person with an audience sitting in front of you there are very few people out there who? simultaneously Didn’t do great in school I felt like it was failing them But never the came out with an appropriate sense of confidence about what they themselves could achieve those don’t usually go hand in hand and I feel like it’s this recipe to actually be a source of inspiration for The many students out there that are feeling similar things, but don’t have the corresponding confidence right yeah, I mean I think that is something that drives me is kind of that empathy for you know you know It’s very easy for me to look back and see how things could have gone very differently You know I wasn’t a great student I got into like an in-state school, and then proceeded to fail out twice in college I think in total I took calculus four times and failed at four times, so not a lot of great positive feedback there But I feel like I got very lucky because this was in the mid 90s You know the sort of peak of the dot-com boom And so you know knowing anything about computers almost guaranteed you a job and people weren’t asking a lot of questions And so I was able to kind of get my foot in the door in terms of industry And then you know once you start getting experience in industry and that started clicking for me But like how often does that happen to someone at the peak of an industry that they are well suited for? So it’s very easy for me to kind of look back and see yeah That’s just very lucky in that situation and it’s easy for me to imagine someone who’d be in the exact same situation and and yeah not have that insight or not get lucky in the ways that I did and Maybe that’s what drives me is to sort of try to help that person who is really just me given that Maybe we should reframe the original question what’s next for Benny to the channel that? Addresses those people most directly just the story that you’re telling right now I think the fact that that story is told is in and of itself a meaningful thing and can be a source of inspiration Showing people who enjoy tinkering how to build their own computer like this obviously addresses that in a in a much deeper way But if that was the central thing in mind saying okay, there are others who are like you who might not be in a similar place in history and Industry, but need some direction right what is the set of videos that is most helpful to them yeah? That’s a good way to frame it and Because I think that is in some sense like that’s the part of the videos that I’ve made that I find kind of the most inspiring as seeing People who have kind of taken the videos and then extend I actually built the computer themselves and then posted pictures just sent me pictures or posted videos of Their own thing and in some cases they’ve taken the design and sand you know Understood it and and continued to build on it, or you know do more complex things add more memory. Whatever it is well Let me ask you this how many of those are students versus adults? It’s not a hundred percent either I guess I don’t know the exact breakdown But I’ve definitely seen younger sort of high school age kids doing it definitely also seen a lot of adults doing it so Less clear what the sort of life impact. That is I think there’s a but there there exists high school students Yeah, yeah for sure for sure and there’s adults who are doing it with their kids, which I think is kind of cool but I think what is interesting to me is that when I see the pictures and Videos and things that people send me of their own projects You know what immediately comes to my mind is I know exactly what this person knows like they built this thing They have gone through these steps It’s almost in my mind sort of a credential that tells me something You know very meaningful about that person that they have certain interests that they have certain abilities It almost in kind of the way that I couldn’t demonstrate when I was in school Like the system didn’t give me a tool to demonstrate my abilities in this dimension Can we print some kind of been either certificate of accomplishment? That when these people mail you something you have some automated system that Mail’s them this certificate I’m not sure how accredited that would be anything not at the start, but you fast forward 20 years in just you see yeah I think big Thank you So I encourage you to check out the rest of that episode the conversation goes off in a bunch of really interesting directions that are Much deeper than just the question of what I’m doing next on YouTube. We talk about what we think about when we’re making YouTube videos Ways we structure explanations. What makes a good explanation? It’s a it’s a great conversation so check that episode out and check out the whole podcast it’s on YouTube So I’ll put a link somewhere around here somewhere as as one does But you can also subscribe to the podcast on itunes or or wherever fine podcasts are found

  1. I did not realize that you are one of the Ben's from the podcast (I initially heard about it from 3b1b, but did not connect the dots about who the other hosts are) 🙂

  2. Ben, please I would appreciate you explain the process of building an executable (compiler, linker, C language, etc). You have done a GREAT educative work. Thanks.

  3. I love it when it turns out two youtubers I love for completely separate reasons turn out to know each other and collaborate. The podcast looks awesome, and thanks a bunch for the 8 bit computer videos. I have really enjoyed following along and building my own, and it has been a source of many hours of fun for me.

  4. School is not the end all and be all. I used to skip school all the time. What did I do when I did? I spent my days mostly at the public library (around 1980) reading about computers, programming, radio electronics. I guarantee I learned more about these topics than school ever would have. I also concentrated on improving my math and spelling etc… on my own.

    I think this proves that you can do it, and you can do it even if a school fails you. I say to the school… big deal… the inventor of the microwave oven did not have a very good education. There are many such examples down through history. I personally see our education system as more of a problem and hindrance than a help.

  5. Hi Ben, I've been inspired by your breadboard computer videos to really put more of my time into rasp pi projects. I have to admit, that I really really want to do the kind of work you do one day and your videos / podcast has been on my list of things to absorb as I've been working on my self-education. I'm honestly motivated by your story and the high level of skill you seem to have when it comes to computers and I look forward to learning more from your podcast!

  6. I did very badly at school and could not wait to leave as early as I could. I remember at parent-teacher nights one of my teachers telling my Mother, that I was not smart enough to work in electronics and that she should expect that I would not amount to much! I did however have some good teachers, particularly my math teacher, who allowed me to do whatever I wanted in class on the Apple II's, because he saw what I was doing was beyond the simple tasks expected of us on those computers.

    Long story short, I applied for work in the Navy, they tested my IQ in the entrance exam and found mine to be 148. They accepted me for one of six positions, out of thousands of applicants and then I consistently was top of the class in my electronics studies. There was the odd occasion in my digital electronics classes, where the teacher had a mental block and would ask me to finish his point or check HIS work on the board!

    I've since moved into Comp Sci and played critical roles in computer forensics for some huge precedent forming federal court cases. I wonder how many people out there are far more gifted than they get credit for and did not get the opportunities that I luckily did. I so wish these videos of Ben's were available to me when I was learning digital electronics in the late 80's! Awesome work Ben! I'll look forward to checking out this new Ben, Ben and Grant content! 😀

  7. oh my god!!! my two heroes 3blue1brown and Ben!!!you know each other? huge thanks for linear algebra series and the 8 bits computer series, you guys are super awesome!!! in the past years , i rewatched algebra series and 8 bits computer (gain knowledge for a subject that is similar to computer organization ,maybe called computer architecture?) almost 3 and even more times in order to prepare for my postgraduate exam , i'm still preparing , and i'll try my best!!(actually when i was building the 8 bits computer, i couldn't find the EEPROM in my region,so i tried on a software called logisim, and it worked perfectly, later i build a MIPS processor(simple version) similar to the 8 bits architecture , there's a slight difference, but i can say that i will have a very hard time understanding the MIPS architecture if i didn't watch your video, very love you!!

  8. I really enjoyed the series, and I would like to see the computer improved over time.

    I also liked the breadboard animation on here while the podcast was playing, please add a description !

  9. I'm in the process of moving my SAP-1 / Ben Eater build off the breadboards and onto modular circuit boards including a backplane for the central bus and control signals. I haven't done point-to-point wiring on a prototype board in quite a while. My eyes aren't as sharp nor my hands as steady as they used to be but I'm still able to produce decent proto boards. I'll post a video as soon as I get the 8 bit program counter working. I've been designing the boards in Eagle and even got most of the way through PCB layout. I'm hoping to ultimately send off to a custom PCB service. This is something I've always wanted to do.

    I'm really looking forward to checking out the new podcast and for your wrap up of the SAP-1 / Bena Eater project. I already have some ideas for the conditional jump but I'm anxiously waiting to see your implementation. I related to many of the things you said in the podcast segment and feel our careers followed similar trajectories. I'm so grateful I found your channel and that you rekindled that ember that I thought had been extinguished. Thanks!

  10. I'm so happy you decided to work with 3Blue1Brown. You two host my two favorite Youtube channels about the hobbies I cherish the most; electronics and mathematics.

  11. I'm not a big fan of podcasts without video. Nope, "blinking" background doesn't count.

    If you guys had a podcast with Face-cams i would be a lot more interested. Beeing able to see a face when someone is talking just makes this a lot easier to watch for me.

  12. I've only watched a few of your videos but you have an incredible talent for passing on information.
    I'm building a Z80 based computer and even though your videos aren't really relevant on the surface to my goals, you've helped more than any of the other videos on youtube. I have no background in electronics and was really struggling to understand some things, one example was how to read timing diagrams from datasheets.
    I recently watched your videos on programming EEPROMs and your teaching style made it immediately obvious, within a couple of minutes I could understand it as if I'd known for years and looking at a few of your other videos it seems that kind of clarity is consistent all the way through.
    I think one of the things that separate you from other similar channels, is that you don't have any trace of that "wow look what I can do, aren't I clever" attitude dressed up as being informative that many other channels have and you show how it's done without any bullshit…

  13. Amazon carries the book that this computer comes from – Digital Computer Electronics by Malvino and Brown – for $35. Contains all schematics, BOM, etc. https://www.amazon.com/Digital-Computer-Electronics-Malvino-Mn/dp/0074622358/ref=mt_paperback?_encoding=UTF8&me=

  14. buddy you are the best! I love your channel. I'm not a fan of podcasts but keep up the great work with this channel. thanks

  15. I would find it a big waste of potential if you did not go a bit further with your design & attempted to at least do an optimization series on the SAR-1. Maybe it's just a partcount reduction. Maybe it's a layout redesign of all the modules, maybe the potential for a few double-modules where each half has its own omnibus to it's own thing.

  16. You are actually one of the reasons I started my computer engineering studies a couple of weeks ago! Thank you for your inspiring videos on building a CPU from scratch, that helped me a lot with getting started in that area. Keep the great content coming 🙂

  17. Hi Ben, Hope you will See and read this comment. I am a computer science Student and built your computer over the course of one year. I went through lot of trouble with it and learned a lot. Recently I was looking for a part time job, and there is a tech company near me where I sent an application. I was invited for an interview, just the day after I finished my computer project. The boss of the company asked me what kind of projects and stuff i did outside of uni. I showed him the pictures of the computer in my phone and he became very interested. He wanted me to explain every detail and I did. He was very impressed, and guess what: I got that job. I am very happy since then. Thank you Ben. Definitely going to listen to your podcast.

  18. Certainly going to listen! Such a recognisable story, I finished high school by the skin of my teeth after which I spend a couple of years fixing vacuum cleaners. I also got lucky during the dot com hype and managed to get my foot in the door of an ISP. I started literally in the basement doing support but within a year I was doing Unix sys admin and grew from there. Now I'm a self employed software engineer and electronics hobbyist. I managed to become what I wanted as kid all because of that one day in 1996 where I gathered all my courage and rang the doorbell of a small ISP. It makes you realize how much it's really about having a chance to show your value.

  19. Thank you Ben! Totally going to listen to this podcast your words are inspirational. I am a sophomore engineering student and use your videos for study. Calculus in college really does suck, haven’t failed yet lol.

  20. you have no idea how your computer project changed my life, I am completely addicted on it and I can program better softwares now because I understand the basic structure.

  21. Cant wait for more videos! About how long until the schematics are done for the computer? Thanks for making these awesome videos

  22. Ben, I hope that understand the true merit of what you have done here. I am a Special Ed teacher who works at a trade school which includes programing and electrical engineering. Have only just begun watching your videos. As pa person who is exited about the subject and a person who thinks constantly about good delivery of information, I can tell you this is a very special series that I watch wth the same excitement that I used to watch the original Cosmos when I was 12. This series is so well delivered that I believe it should become a standard. I hope that you recognize how helpful and important this series is and that you make sure one it never gets buried or falls into disrepair or dead links and also that someone follows through on posting the schematics for each video. Your pace, voice hand gestures and diagrams are crystal clear. Your use of the oscilloscope at the end of a video to review the subject and to verify are all incredibly useful. I'm not sure about who exactly you are but I would consider marketing this series as it rivals NIDA. I have often considered offering an arduino program at our school but did not quite feel I could pull it off. With the series you have created I now believe that I could. I am figuring out this patreon so I can send you a little money just on principle.

  23. I stopped in because someone (you) was giving direction for where their channel is going. That is important to me to just listen to see what’s going on with my channels of interest. WOW looks like you are filling a very admirable niche in everyone’s lives that are trying to figure out where or how they are to fit in, right

  24. I watched your videos. thank u sir giving such valuable knowledge. plz make videos about machine code or languege. how languages are made ?

  25. technically, your computer is already Turin-complete : the move instruction is turing complete ( https://esolangs.org/wiki/Mov and https://github.com/xoreaxeaxeax/movfuscator ).

  26. I always wanted to see in real how a CPU works, Thanks for this. Please make a video explaining how an Operating system works on a CPU.

  27. HEY BEN I'm a student and I'm into this stuff and my schools electrical department is garbage. So i just buy alooot of parts on ebay for the past 3 years and do hobby electronics at home and after I came across ur vid like 3 years ago about how computers add. I started to plan my own computer and recently I am 85% done after 2 years of learning all about architectures and cpu logic. And now Its beautiful but I'm doing bad in all my classes cause I just work on computers 😛

  28. Just subscribed coming from 3blue1brown! I am looking forward to watch your content. I myself is a software engineer so this your channel right up my alley! Regarding the podcast, you are never to old or young to learn something complicated.

  29. Some ideas that your viewers might find interesting in upcoming videos. Could you compare the breadboard computer with a modern one, as in how many registers in a real computer, are they within the processor or external modules? How many bits on the bus? Multiple buses? What other types of modules would a real computer have? Bus within the processor? etc And some info on machine language. You created your own on the breadboard computer, which was awesome and gave me my first real understanding of what machine language is. But how about on a real computer? Is the language different for each machine? or is there an established standard basic language that works on all machines? Would love to have you explain a more complex machine with the background you have established with your breadboard computer as a foundation. Thanks for putting together this excellent video series!

  30. your channel is beautiful, your explanations are extremely clear and concise…and most importantly your story is extremely relatable. i'd love to see more from you; i've already subscried to your channel and will definitely check out that podcast.

  31. Are you planning at the end on moving the computer from the breadboard to a custom PCB? Or build a different one on a PCB?

  32. Ben I've just discovered this amazing channel, I'm looking forward to see your videos, even though they are like 2 years old. Nevertheless, I think I will enjoy them.

    Grettings from Peru.

  33. Wow. Why haven't I met you before? I've been watching videos in your channel about your 8-bit computer for almost 5 hours tonight, but now I've seen this one and I've felt like commenting. Because I've felt so identified with those difficulties handling how the education system works, and I've tried to fight back those problems teaching maths and more science to high schools students in my town for some years, as I love maths, computing and teaching everything I can. In fact, I've learned a lot from teaching, even more than from studying.

    I'm definitely listening to you three these days.

    Oh, by the way, a little off-topic, but I've recently taken an EEPROM from an old TV and started playing with it because of your videos. I've got lucky as it has an I2C bus and I didn't have to get any more components to use it. Today I've read and written on it for the first time and I've felt sooo good, it's been such a pleasure as it's been my first time doing that. Thanks a lot for your work, I really appreciate your explanations. Damn, I love the Internet, this way of teaching and learning is one of the best things we will ever have. If I don't get a job soon, I may start something. I don't know what, I don't know how, but I often think about this.

    Well, I'll shut up now. Thanks a lot again.

  34. Hi Ben,

    Thank you for posting your thoughts and work here. Such an inapiration!

    I don't know if it was asked, or not and I can understand if this may seem silly, how much background, in years do you have on electronics and computers to begin with?
    I am a novice and would like to gain more knowledge, and with all this info out there, at times it seems overwhelming and hard to find focus.
    Any advice?
    Kind regards, Adrian

  35. an excellent bread board build project would be to build a computer systems bios …. literally a power on and access a drive and monitor and your bread board computer and connect to a network … which could be another bread board setup of network coding a networkable system

  36. It's kinda strange when you see a person for the first time after having heard them many times. You sorta develope this week image of what you think they look like based on the voice but when you see them you realize you weren't even close. Lol but your vids are brilliant.

  37. Hi Ben, I just found you channel and your videos are fantastic and very clear. I think they will go a long way helping students and hobbyists immensely. When I studied electronic engineering the quality of the the teaching was hit and miss. I did well when the lecturer taught in a concise manner and was enthusiastic about their subject, and not so well in subjects where the lecturer didnt really want to be there teaching.
    My electromagnetics lecturer was fantastic, he made a difficult subject so interesting and was patient enough to see me out of lecture time to help. Now thats what I do for my day job although I still like electronics and tend to do that more as a hobby. The quality and clarity of teaching and enthusiasm is everything, in my opinion.

  38. Hey Ben, discovered your videos a little over a year ago. I was at a coffee shop and ended up watching the entire networking series on a whim. Then I saw the 8-bit computer videos and they inspired me to go get my master's in computer science after a less than successful job hunt with my English BA. I'm currently back in school studying compsci and I'm really happy with my decision. Just wanted you to know that you were a big part of that and a real inspiration to me.

  39. You two are doing an amazing job ! Thank you for your content, would it be possible to have the podcast on Spotify ?

  40. I want a Ben Eater certificate that would be great but honestly , Im like gradeschool compared to Bens knowledge even though Im age 50 LOL . Thanks Ben for all you do.

  41. Oh my god you're like 20 years old! I watched your 8 bit computer video and assumed you were some wizened 60-year old or something.

  42. You make some amazing content, I love listening and watching your videos. When running I'd rater listen to some good content that you put out them my music, lol. Keep it up.

  43. I have just finished binge watching your breadboard computer series. I couldn't stop watching. Fascinating, entertaining, useful, informative and impressive. Please don't stop creating and teaching.
