Show HN: I made an open-source laptop from scratch
Hello! I'm Byran. I spent the past ~6 months engineering a laptop from scratch. It's fully open-source on GH at: https://github.com/Hello9999901/laptop https://github.com/Hello9999901/laptop
- snake_doc 2y agoOkay, I'll help him humble brag: Bryan is in his last year of high school. </end> Keep building!
- GardenLetter27 2y agoYou study quantum mechanics in High School in the USA?
- byran 2y agoWe discussed wave functions, probability, fermions/bosons, did calculations for particle in a box, the Schrödinger model, and went just up to deriving the hydrogen atom. Nothing super fancy, but it was one heck of an experience!
- stackghost 2y agoBut did you win the Putnam?
- dang 2y agoFor those who don't know, stackghost is referencing this classic moment on HN: https://news.ycombinator.com/item?id=35079 https://news.ycombinator.com/item?id=35079
- throwup238 2y agoI wonder how @sanj feels about their moment of fame (they’re still active on HN).
- dang 2y agoAs I've pointed out before, his concession at https://news.ycombinator.com/item?id=35350 https://news.ycombinator.com/item?id=35350 was both witty and graceful. It's great that he's still active here! and anyway he's done a ton of things that are a lot more important than that bit.
- throwup238 2y agoI hope that’s in the highlights :)
- GardenLetter27 2y agoIt's really interesting, in the UK I don't think we did (but I later studied Physics at university) - but we did have Further Maths which covered more advanced mathematics. Also your project is incredible btw, maybe look into robotics too.
- alias_neo 2y ago> in the UK I don't think we did Perhaps you didn't go to a high school quite like this one: https://exeter.edu/admissions/financial-aid/tuition-costs/ https://exeter.edu/admissions/financial-aid/tuition-costs/
- Izikiel43 2y ago> High school quantum theory > Nothing super fancy Yeah, that's college level stuff, it's pretty fancy for high school, you go to a nice place :)
- mattnewton 2y agoSome do- He thanks Phillips Exeter at the bottom of the project page, which is a very fancy private highschool, probably the best in the US.
- macNchz 2y agoI went to a peer school that had at least a couple of math teachers with PhDs—my friends at the time who took their classes were, if I recall, nationally competitive in math olympiads.
- govg 2y agoNot all high schools but the US has some schools which allow you to take very advanced material / even get a head start on your college credits.
- mschuster91 2y agoWe had a cursory introduction at least about 15 years ago in Germany, it's not that far off.
- rafram 2y agoIt's more possible than you'd think! The options are basically: - Go to a fancy private school like Phillips Exeter - Really luck out and get into a great public STEM magnet school - Homeschool and take private classes / have very smart parents
- rafram 2y agoOh, or: - Concurrently enroll at a community college (a really great option that I think every country should have)
- jogu 2y agoI tested out of high school and went to community college instead, one of the best decisions of my life.
- 2muchcoffeeman 2y agoCan't tell if this is sarcasm.
- rafram 2y agoThe community college option is available to anyone who’s willing to spend a couple evenings a week taking classes, so I don’t think it’s really that out of reach. Most countries don’t offer their high school students any opportunity to study material that advanced.
- 2muchcoffeeman 2y agoYour first 3 options are mostly “be born to the right parents”. So I couldn’t tell if your remark of “it’s more possible than you’d think!” Was serious or not. Hell I went to a really selective school. But even then, within that the top students, whom I was not one, got to do some extra stuff that would have greatly interested me and I would have been able to do. But my grades in humanities weren’t good enough to be one of the best.
- 2y ago
- TeMPOraL 2y agoIn the high school in Poland I attended, I lucked into being in a class with a university TA assigned as physics teacher, and he did manage to sneak in QM - more-less the same stuff as 'Hello9999901 listed in their reply. (He also taught us differentiation in the first semester, and basic integrals in the second, because as he said, you cannot learn physics properly without those tools. This annoyed the heck out of our math teacher; she ended up deciding that, if we're learning this anyway, we might as well learn it properly - and gave us a much heavier intro to calculus in the last months of the last year.)
- volemo 2y agoYou don’t study basics of QM in your high schools?
- apricot 2y agoThe USA has some great schools. OP goes to Phillips Exeter Academy, which is an exclusive private school that ranks among the best high schools in the country.
- chuckwfinley 2y agoThis is incredible work for anyone, let alone a high schooler. Seriously impressive! I hope this turns into something I can buy (maybe a diy kit), in the future!
- byran 2y agoThanks! I've been considering it (or enough detailed instructions to build one) since starting the project. I need to get a working model first though ;)
- ricardonunez 2y agoWe are going full circle, Woz will be proud.
- d3rockk 2y agoHOF HN post.
- aunver 2y agoCongratulations Byran, this is really impressive work!
- teddy__d 2y agoamazing job!!
- baritodespa1 2y agogg byran well played
- handfuloflight 2y agoWhat's the BOM?
- byran 2y agoThanks for the question. I'm working on compiling the BOM in these few days. A preliminary R&D BOM is here (apologies, it's in Google Sheets): https://docs.google.com/spreadsheets/d/17arbJvPqW6koqEJwAzne7z5z2sndyQx2O3cI5NKfjhY/edit?usp=sharing https://docs.google.com/spreadsheets/d/17arbJvPqW6koqEJwAzne...
- imcritic 2y agoThis seems to list some components multiple times in a versioned way, did I get it right that this is rather a whole list of components you've bought while working on this project rather than the final list of the components needed to assemble the notebook you've built?
- _fw 2y agoHoly fuck People like Byran live amongst us Making their own laptops but from SCRATCH Imagine how good this man’s pasta carbonara tastes
- byran 2y agoThank you so much!

- ge96 2y agodamn it looks clean
- spicysev 2y agoHoly hell. This is so cool ~ an admirer
- Palomides 2y agonice work! how much was it to get the case milled?
- bflesch 2y agowell done, thanks for documenting and congratulations on completing the project!
- byran 2y agoTruly appreciate it. I spent many weeks afterwards documenting the steps as thoroughly as I could. My email's on the site if anyone needs to reach out, as well. :)
- laidoffamazon 2y agoVery nice. Wish there were faster SOMs than the 3588 but maybe in a year or two. Looks like an MIT admissions portfolio project. Don’t know if it fits the uniqueness category for it but I guess the quality of the end product makes it good enough. Admittedly this isn’t fully open source like the Novena or the Reform but I doubt adcomms care. I just wish I was rich enough and skilled enough to be able to spend $4.5k on a neat project like this.
- byran 2y agoThanks for your suggestions and criticism! Much appreciated. Which aspect of it (aside from the SoM, which I admittedly do not have the R&D to make in this timescale) isn't open-source? I'd love to hear your thoughts. The Novena and Reform are amazing pieces of engineering, but I believe they sacrifice the portability and looks for repairability which some people certainly prefer. I wanted to aim for something that a non-technical consumer might look and say "hmm, nice laptop!" and not think it came out of the matrix or built it myself. In terms of college, still waiting :)
- andrewmcwatters 2y agoSick! Finally someone posting something that puts the “hacker” in HN. Love the parts research you did.
- byran 2y agoThank you so much!
- j3s 2y agoVERY impressive. the laptop looks great. wish you could manufacture and sell the thing, i'd consider one :)
- byran 2y agoMaybe, depending on reception! I geared it so it could be manufactured at a semi-small scale. Unfortunately, I don't have the capacity to make them myself :(. Thank you for the interest!
- mwcampbell 2y agoNot to take anything away from this amazing achievement, but if you want a similar open-source laptop, also based on an RK3588, that will actually be manufactured and sold, check out the MNT Reform Next: https://www.crowdsupply.com/mnt/mnt-reform-next https://www.crowdsupply.com/mnt/mnt-reform-next
- MrDrMcCoy 2y agoThis is fantastic! I hope to follow in your footsteps as soon as a decent RISC-V board can supplant that RK3588.
- byran 2y agoI'd love to see one; hope to see that day come!!
- junon 2y agoThis is so, so cool. Reminds me of Clockwork Pi stuff. Thanks for sharing :)
- petsfed 2y agoThis is really cool! There are some obvious next steps for improving the polish on this, would you say you were more resource constrained, time constrained, or skill constrained? For instance, did you put any thought into making flex PCBs to make the cable routing easier? I also think the concept of a laptop with a removable wireless keyboard is brilliant, and I think your implementation is a lot cleaner than e.g. the Surface or the iPad's case-keyboards. If I had a laptop that did that, it would be my go-to travel machine. One less thing to cart around.
- byran 2y agoHey! Thank you for the question. For sure, it's not a polished product and I don't mean for it to be. It works surprisingly well. (I've used it as my daily driver for school) With college apps and school work, the time was tight. I'd say that was the most limiting. Of course, resource and skill played its role. I did consider flex PCBs, but I didn't have the time to follow through with all the ambitions (i also wanted an FOC input sigh). I'm honored that you think my keyboard implementation is nice! I put a lot of thought into it — truly. Oh btw the keyboard works just as well as a solo device. I've used the keyboard more than the computer in some ways. Thanks!
- petsfed 2y agoIf you keep this idea alive (and I hope you do!), you might consider shrinking the keyboard battery and designing its docking configuration so that it automatically charges from the main battery when stored in the laptop. A 3 month keyboard battery capacity seems sort of excessive when its mechanically part of a machine that charges daily. I think one of the limitations to the keyboard concept you have is that it complicates using the laptop base as a stand for the screen in a tablet configuration. Outside of tablets with fully detachable keyboards (e.g. the Surface or the iPad pro), I don't think anybody has a good design for that. Was a touchscreen ever a consideration for stretch goals or design for expansion?
- daquisu 2y agoRegarding a laptop with a removable wireless keyboard, ZenBook Duo has that, although the touchpad is removed with the keyboard. It also has two screens and its own stand, I use it as my travel machine.
- camtarn 2y agoGenuinely incredible work. Looking forward to seeing what other cool projects you do in the future.
- chironjit 2y agoI actually spent quite some time trying to build a custom driver for a custom screen for my Framework 13, only to burn the screen driver. Very impressed by what you have done here. Kudos to you on achieving designing and building a whole laptop!
- byran 2y agoThank you so much! If you'd like to discuss further, please let me know! My email is in the website. I have a Framework 16 and have tons of ideas. Never got around to it though. (I also burned a few screens, and had 3 as backup haha).
- KolmogorovComp 2y agoVery impressive work, and also nice video editing. Congrats.
- amelius 2y agoI'm curious how the USB-C connectors are made to the outside of the enclosure. What I've found is that it's a bad idea to use USB extension cables; these can introduce bit errors if e.g. you copy large amounts of data (order of terabytes). It's much better to insert a USB drive directly into a carrier board, but this is not always physically possible.
- byran 2y agoIt's almost standard to have the USB-C have extra wiggle-room (around 1mm or so). Then, the housing is 1mm past the USB-C connector. That's how the casings are made so that when you stick the connector in, it's flush or nearly so. I agree with USB extension cables concerns too! The error would increase depending on the quality (impedance, power, etc.)
- amelius 2y ago> Then, the housing is 1mm past the USB-C connector. Yes, this is often the case but sometimes the USB-C connectors are on the same side of the board where you also need to plug in some cables that you need internally (maybe even other USB devices). Thus the option of letting an USB-C port stick out on one side of the enclosure is not always available. > I agree with USB extension cables concerns too! The error would increase depending on the quality (impedance, power, etc.) Yes, and the user of your device (who doesn't see the internal cable) will assume that they can plug in their own cable, so you'll have two cables.
- madsmith 2y agoAmazing project.
- lxe 2y agoThis is one of those special HN posts that demonstrates outsized excellence on the author's behalf. Watched the video and I'm very impressed.
- tuktuktuk 2y agoAmazin! what's the total cost for you?
- byran 2y agoHanging around 5 grand. Unfortunately the R&D process was rough! The R&D BOM is linked below, feel free to take a look. If you were to build it, I'd estimate it costing around 1500 dollars (or less).
- someothherguyy 2y agoBack in my day, I thought spending $50 in wood shop was rough.
- megous 2y agoYeah. My "budget" for similar scale project (sw, fw, hw, enclosure co-design) in high school 24 years ago was about $200. I'd have loved to have these kinds of resources/lab tools access. I even made [private, so that tool makers did not patch the holes/obfuscate] cracks for Eagle, HI-TECH C compilers and Solid Edge, to have some nice SW tools to work with, without arbitrary limits. But I sure had plenty of time, and it was fun to always be learning something new. Simpler times when it was out of reach to have anything done for me, like prototype PCBs and let alone assembly. :) These days are absolutely crazy in comaprison, with all the ready-made SBCs or SBC modules, and free software, and like $4 PCB prototyping services and CNC machining, 3D printing, $15 powerful FPGAs, $7 fully Linux capable 1GHz Cortex-A7 tiny computer modules for bread-boards, and cheap components from China... Still remember going to a shop buying single unit amounts of SMD resistors and capacitors over the counter. Now I can get 4000 unit SMD sample book for a few $ and never think about it again. Even my 2000 self would be able to afford it without much trouble. It's kind of a force multiplier easily available even for high-schoolers.
- tuktuktuk 2y agoThank you for sharing!
- nashashmi 2y agoLooks good. Could be a small step to my vision for a dock dependent palm sized pc with high powered cpu connected by a single USB C with no other ports except for micro sd. And backed up by a mini battery for power stability on low watt chargers.
- byran 2y agoThanks! Have you taken a look at the Khadas Mind [1]? Super similar to what you're talking about with the handheld PC. [1]: https://www.khadas.com/product-page/mind https://www.khadas.com/product-page/mind
- deleted 2y ago[deleted]
- nashashmi 2y agoWow. Precisely what I have been looking for. This is great. And mind 2 is even better.
- mschuster91 2y agoHoly. That's an achievement very few people can claim. Wonder if HN has a "hall of fame", a worthy entry. You did the smart thing there with the SoM (for the uninitiated: power sequencing to individual parts of an SoC and its external components is an epic hassle to get right and that's assuming you actually have proper documentation - without it it's an utter pain), but how in hell did you get the high frequency stuff working out on what was likely your first or second try? This is IMHO where your work really shines. USB-C, DisplayPort (at 4K to boot) and PCIe at modern speeds are all but black magic to most, this isn't digital any more, this is good old analog circuitry and physics at work that most people don't even learn in university any more.
- byran 2y agoThank you so much — yes, that was the hardest part of this entire project! I spent 2 months getting eDP working (second PCB thankfully). I had the honor of learning high speed signaling from the best. I met some super cool people from Silicon Valley and research universities (from past work, like the MUREX Ethernet Switch). The ZMK Firmware community too!
- mschuster91 2y ago> from past work, like the MUREX Ethernet Switch Just looked it up... https://news.ycombinator.com/item?id=40694254 https://news.ycombinator.com/item?id=40694254 for those who want a direct link. Jesus. Wish I had had even a fraction your talent at that age. Most impressive.
- byran 2y agoI truly appreciate your encouragement. I can only imagine how successful you are! Thank you!
- aio2 2y agomy guess is when doing college applications, you figured you had to do something special to get into a good college, so you decided to do this lol Doesn't matter why, pretty sick. I'm studying physics myself, so its pretty inspiring to see you do this
- byran 2y agoThank you so much! The story behind the laptop was quite interesting — my friends and I were going to an athletics event far away, and he brought up the idea that I should make a laptop for my senior project as a joke (our school offers 1 free class for a "project", graciously funded by the school). I said "hell yeah." That's pretty much how this came to be, college didn't play much of a role imho. And best of luck studying physics!
- triyambakam 2y agoHey Bryan, great work and very inspiring. This has me meta curious about how a project like this is possible. Besides the support from your school, I imagine that your parents have been a big part of your success?
- gerdesj 2y agoAt which point was the mental map created within Obsidion and did you really need it? You are clearly a very clever person and you do not need a web app wiggly graph thingie to throw ideas together. There's no need to gild a lily! Please keep the faith - I love that you are focussed on being altruistic and sharing your skills to the benefit of everyone. Thank you.
- deleted 2y ago[deleted]
- montroser 2y agoByran... This is seriously impressive. You are very blessed to be so capable in so many disciplines -- design, hardware, software, storytelling. It is a massively complicated undertaking, and you executed in style. Nice work, and remember to use your formidable powers for good!
- byran 2y agoThank you so much! For certain; goodness without knowledge is weak and feeble and knowledge without goodness is dangerous. It was a truly difficult undertaking! I was ready to quit at so many moments, but I always think about the final mission of sharing this little piece of knowledge with the world. :)
- MegaDeKay 2y agoMy hat is off to you, good sir. Way off. This is an unbelievable accomplishment, doubly so given that you're still in high school (!!!), triple-so given the time you did it in, quadruple-so given that you did it all yourself, etc etc etc. I was reading this over thinking "this guy should be working for Framework". It would be a total win-win.
- byran 2y agoThank you so much! I'm currently working for Keychron!
- freedomben 2y agoIf you do decide to look at framework, I can help you get your resume in front of a high level decision maker. I agree you'd make a great fit with framework.
- byran 2y agoWoah! That would be amazing! I sent you an email just now. Thank you so much for this opportunity!!
- guywithahat 2y agoSometimes I wonder why I didn’t get into MIT, and then I see people like this exist
- ttoinou 2y agoI’m pretty sure it’d take me 7 hard years of studying electronics / hardware / linux to get his level
- umrashrf 2y agoI’d like to follow up to see how it handles heat or excessive heat if any
- byran 2y agoI played Minecraft (epic gaming) with friends for a few hours, no problem! The massive heat capacity of the copper + heatpipe + active fan is good enough.
- p0w3n3d 2y agoIt might be a stupidly specific question, but may I ask what is the screen resolution and how many FPS you got? I am asking because I've been considering buying an Orange PI with RK3588 for gaming purposes.
- 11944351 2y ago[dead]
- jwr 2y agoCongratulations! From someone who does mixed electronics+mechanical design: this is hard. There are moments of desperation where you realize that everything depends on everything else, and there is no way to achieve all of your design goals. You then have to realize that engineering is all about compromises, and move on, compromising — but this is very difficult. It's easy to get bogged down in details and dependencies and never finish the project. It's very impressive work and it makes me so happy to see real hacker news on HN. This is real hacking.
- byran 2y agoThank you so, so much! You phrased it so well. The moments of desperation really hit you hard. I have uncountably many loose ends, but oh well, bad engineering :(. Honored that HN thinks I'm a hacker :)
- geerlingguy 2y agoAlways fun to read an article like this, for humility's sake. Wow! And I'm guessing if he attempts a 2nd edition, it'll probably be even thinner, lighter, and faster!
- byran 2y agoOh my god! Jeff — huge fan and subscriber!! Thank you for your words of encouragement :). Your videos have been a huge source of inspiration for me.
- eddywebs 2y agoThis is really cool ! Kudos for getting this started. I wonder if initiatives such as one laptop per child could have been effective with this kind of approach. Eitherway I hope this project goes along way as I could see its application not only at home but also in developing nations.
- xarope 2y agoWow this is fantastic, great job! I hope this heralds a new era of HW engineering. P.S. @Hello9999901 any relation to "Bunnie" Huang?
- byran 2y agoHaha I wish, but no. Just surname coincidence.
- webprofusion 2y agoThis is what the internet was invented for.
- byran 2y agoThank you!
- stuckkeys 2y agoHolly crap. This man is the messiah of tech. Keep going my guy. That is so impressive. I look forward to what you do next.
- reactordev 2y agoMan!! This is sooo impressive. I did a little research on making my own motherboard (not even for a laptop) and didn’t get anywhere nearly as far. I just want to throw money at you! We need an open source laptop!!
- byran 2y agoThank you!! After schooling is done :)
- eviks 2y agoHave you thought about finally adding a split ergonomic keyboard to a laptop instead of the standard slab?
- byran 2y agoThat's a sick idea too! Wouldn't be too hard. I'll keep that in mind never thought of it before even though I've used my fair share.
- eviks 2y agoThere was a very old ThinkPad design that allowed the keyboard to take more space than the width of the laptop, but that was also bad old non-split layout But at least not wasting existing left/ right side space and having a gap in the middle instead would be a nice start Or maybe even get to the best of the portable/non-portable worlds: since the keyboard is wireless, you could detach 2 halves of the keyboard and place them on a desk at ergonomic shoulder distance And this would allow you to also ergonomically position the laptop itself for a better screen position - vertical, just like your desktop monitor ThinkPad: https://youtu.be/RRHFi_l9UR0 https://youtu.be/RRHFi_l9UR0
- xarope 2y agoThe 701 "butterfly"? It was cool for its time. https://en.wikipedia.org/wiki/IBM_ThinkPad_701 https://en.wikipedia.org/wiki/IBM_ThinkPad_701
- noisy_boy 2y agoFramework team, hire this guy, when it's legal :)
- amatecha 2y agoMore suited to working with MNT Research[0] which makes actual certified open source hardware[1] :) [0] https://mntre.com/reform.html https://mntre.com/reform.html [1] https://certification.oshwa.org/de000017.html https://certification.oshwa.org/de000017.html
- aragilar 2y agoIt looks like https://www.crowdsupply.com/mnt/mnt-reform-next https://www.crowdsupply.com/mnt/mnt-reform-next and the anyon_e use the same SoC and similar parts (e.g. Cherry MX ULP switches). I wonder how much of that is they're the only parts that would be put in such laptops?
- dataflow 2y agoThis is crazy. Hats off to you. My guess is you'll have recruiters knocking on your door yesterday, trying to grab you before the next one does. Whatever you do, don't let your talents go to waste (corporations can do that), and think about your long term success, not whatever they dangle in front of you for the short term. You're going places.
- byran 2y agoThank you so much for the heartfelt advice! I'll keep that close to heart :)
- bboygravity 2y agoTip from an experienced EE: try to avoid middle-men recruiters at all cost. Go straight to the company you want to work for. Or better yet in your case: start your own company :p
- amatecha 2y agoI clicked through dreading that it's got a Raspberry Pi at its core, but no, RK3588 (same as MNT is using now)! Very nice. Ultra kudos for making it truly open source. Great work!! <3
- byran 2y agoThank you! Yup, Raspberry Pi's great an all, but the RK3588's performance is king (and RPi would've also saved me many nights of head-banging at the software).
- jiveturkey 2y agocame here to shit on this project, that there was no way it was open source down to the ME, like a raptor or framework computer. absolutely required IMO to be considered open source. i didn't find any firwmware in the repo (didn't look exhaustively) but I did find that the SoC this is based on is supported by https://github.com/edk2-porting/edk2-rk3588 https://github.com/edk2-porting/edk2-rk3588 . AFAICT the azoteq trackpad has proprietary firmware, so if that's true then i won't call this laptop fully open source. but from a practical perspective, i am much less worried about that then the boot path. love the keyboard, wish i could test drive it! so instead, i was left very, very impressed!
- felipelalli 2y agoBrabo.
- nrp 2y agoSuper impressive, and awesome to see that you were able to use Framework Laptop hinges. Let me know if you need more. We have a ton of remaining 3.3kg ones!
- byran 2y agoHey Nirav, super super honored that you saw this! I've always looked up to you guys for inspiration and guidance. Thank you for the offer! Although I probably won't be mass-producing open-source laptops like you (i have a framework 16!), I would love to meet you. Would that be possible?
- nrp 2y agoJust sent you an email.
- byran 2y agoThank you!
- xarope 2y agoCan I just say that the fact HN can facilitate this sort of meetup is just, wonderful.
- azath92 2y agoThis is the best of the internet. Connection based on interest, appreciation, and mutual respect facilitated with a high degree of good faith. Hope you folks connect fruitfully, and also appreciate that you kept some of the "sent an email" and "thanks" public. Getting to see that this happened has given me a real boost.
- eadmund 2y agoThis may be the coolest thing I’ve seen this year. Wait, it’s January? This may be the coolest thing I’ve seen this year and last. And possibly the year before. Well, well done. Good luck to you!
- byran 2y agoThank you so much for your kind words!
- unethical_ban 2y agoIf you can do something like this, then you'd be great at Factorio! :) On a less joking note, I wonder if I'm decent at Factorio, I could learn this.
- fifticon 2y agonot only that, you can use this laptop to _play_ factorio!
- op00to 2y agoHey you didn’t mine the rare earth minerals! This ain’t really from scratch! Just joking, incredibly impressive!
- jballer 2y agoIncredible work
- AnthonyMouse 2y agoI've long been disappointed that we've never really gotten standard laptops, in the way that there are ATX standard desktops. The laptop form factor hasn't really changed in decades. It's a rectangle with a screen in the lid and a keyboard in the base. Below the keyboard is a battery and a system board. The battery has to be replaced when it wears out and the system board when it becomes obsolete, but then why aren't they both fungible parts? If you take any arbitrary ATX PC from many years ago, you can replace the system board/CPU/memory/storage with modern ones and carry on using the same chassis, screen, power supply and keyboard provided they meet the required specs for the new parts (and they often do). So why can't I do this with the average laptop, instead of having to replace $200-$300 worth of perfectly good parts or more each time I want an upgrade?
- coryrc 2y agoI think my laptops have been split between mechanical and hardware EOL. I don't think the mechanicals would ever go for two lifetimes. But I actually take mine around places and am a little clumsy.
- AnthonyMouse 2y agoMechanical what? The keys? There are people who have had the same keyboard for 30 years. You don't have to design things to be disposable junk. That's even part of the advantage. If you want a higher quality chassis made of rubber-padded metal that can survive being dropped off a table then you'd only have to buy it once.
- numpad0 2y agoNo one personally buys a Toughbook new for home use.
- AnthonyMouse 2y agoBecause you don't pay that much for something to be durable if the durability will just be defeated by obsolescence. Whereas if you could upgrade it to later generation processors, clumsy people would save themselves a lot of trouble to buy the chassis once.
- kuon 2y agoCongratulations, this is awesome. I worked on medical devices where I did both hardware and software and it is really hard. I wish you the best and I really hope you'll continue to use your skills for good and open products.
- itsmemattchung 2y agoJust skimmed the YouTube video and I'm blown away as well ... anytime my ego needs to get checked, I just scroll through HN posts. Truly impressive
- Vekz 2y agoBryan, thanks for publishing, this is great work. I'm curious if this this build could fit and swap a 13.3 E-ink screen with display board. Some open source hardware synergy with https://github.com/Modos-Labs/Glider/tree/main https://github.com/Modos-Labs/Glider/tree/main
- 6510 2y agoBesides the enormous effort, what did the part cost?
- mllev 2y agoSo how long is the trip to Earth from your home planet? And do you plan on staying a while or are you just here for 6 months to humiliate us with your superintelligence?
- lemper 2y agoaight, mate. that's definitely impressive. no, not only impressive, i believe it can help you land a great job somewhere.
- ornornor 2y agoI wish I had your talent, that’s impressive! And it took you 6 months only.
- marssaxman 2y agoThis is one of the coolest projects I've seen here in a long time. Kudos! Your dedication to completion is admirable.
- shahzaibmushtaq 2y agoAn amazing challenge you set for yourself and pulled it off in 7 months is admirable, commendable and exceptional. How much did it cost to make this open-source laptop? My wild guess is it's around $500-750.
- chrismorgan 2y ago> A highly integrated, high end, open source laptop. Not sure what’s meant by “high end” here. Performance is a rather important aspect, and the RK3588 this uses will make it slower than almost every laptop on the market. Practically all are twice as fast (both single- and multi-core), most are 3–5× multi-core, and the best approach 7× (paired with 2.5× single-core). Looking at Lenovo India, they sell three laptops that are slower multi-core and maybe slower single-core (running Celeron N4020 or Athlon Silver 7120U); after that, they’re all at least twice as fast, in both single- and multi-core benchmarks. (I’m simplifying to PassMark’s single-/multi-core scores, using <https://www.cpubenchmark.net/cpu.php?cpu=Rockchip+RK3588&id=4906 https://www.cpubenchmark.net/cpu.php?cpu=Rockchip+RK3588&id=...> and such.) From <https://www.byran.ee/posts/creation https://www.byran.ee/posts/creation>: “In many aspects, the Rockchip RK3588 is the fastest consumer-procurable chip on the market.” As someone not involved in these spaces, this was my vague impression, but it still ends up disappointing if you simply can’t get good performance for a project like this because only bigger companies can buy the better-performance things. It’s an extremely impressive project, but unfortunately will be rendered not viable for many—probably most—people for this one reason. That makes me sad. I wish they’d sell us the good stuff.
- utopcell 2y agoI suspect that utmost performance was not the main focus of the project. Nevertheless, the complexity of the project would not be different if a different CoM was to be adopted. Even creating a custom CoM doesn't seem that much more complicated, as the daughter board is as complicated since it already needs to handle high-frequency traces as well. Super impressive project!
- barrkel 2y agoThere's a way to phrase this comment better, which reflects sadness on the facts of the market, and isn't a kind of attack on the author.
- justmarc 2y agoA huge congratulations to Bryan, a wonderful achievement and a remarkable result! Keep it up Bryan! It's lovely to see HN so nice and friendly, keep it up guys!
- Justta 2y agoMost of the older LED display have standard 30 pin or 40 pin connection. Lacking standard is keyboard connectors. Most standard are battery and fans. Maybe laptop should have two layers or parts.One for Motherboard and memory and another for connectors, fans, power supply, battery etc. Then we can have more standard even if a little thicker.
- vim-guru 2y agoCongratulations on a beautiful build!
- vhiremath4 2y agoA seriously impressive piece of work, especially only in 6 months. Bravo! :)
- teleforce 2y agoAnyone know the amount of RAM available for the laptop? Personally I'm a bit disappointed that it's based on Rockchip. If someone can come up with low cost open source laptop with RPi compute module 5 with 16GB RAM I think it will selling like hot cakes given the software and hardware eco-system that exist round RPi [1]. It just that the compute module has yet to come with 16GB RAM unlike the normal RPi 5 but it will probably just around the corner [2]. [1] Compute Module 5: https://www.raspberrypi.com/products/compute-module-5/ https://www.raspberrypi.com/products/compute-module-5/ [2] New 16GB Raspberry Pi 5 on sale now at $120 (191 comments): https://news.ycombinator.com/item?id=42642873 https://news.ycombinator.com/item?id=42642873
- actionfromafar 2y agoI think 32 is the limit for the motherboard.
- numpad0 2y agoNo hardware sell like hot cakes relative to the pain and cost incurred.
- teleforce 2y agoCare to explain?
- paines 2y ago> Personally I'm a bit disappointed that it's based on Rockchip. Why would you? You mentioned Raspberry where, compared to the competition, you pay more for the name while they deliver even the same capabilities or more bang for the buck... Don't get me wrong. Huge Raspi fan here. I have 3 models laying around here, because they are the easiest to purchase. But the competition is not to be overlooked. Also, aren't the compute modules strandarized or compatible? So it should be interchangeable, no?
- teleforce 2y agoBecause it's the eco-system for software, hardware, firmware, drivers, books, documentation, blogs, papers, training modules, etc. It's the same reasons Nvidia thriving for ML/AI while the rest are playing catch up.
- t4TLLLSZ185x 2y agoFor those that missed it, this Engineer is in _high school_. Byran, I have been a professional engineer longer than you have been alive, I can tell you right now that I have met very, very few people that would have the motivation, skill and sticktoitivness to pull this off.
- denysvitali 2y agoAnd the time. Don't underestimate the amount of free time people have when they're in high school (vs when you have a family / intense job). Having said that, even with unlimited time this is such an awesome achievement and really shows the dedication. Well done!
- helboi4 2y agoYeah I did some crazy things when I was in school. Had so much time.
- MonkeyClub 2y agoAnd energy... I do miss those days.
- Vinnl 2y ago...and money, apparently? How do you pay for all this in high school?
- sibeliuss 2y agoSupportive parents. Bless
- helboi4 2y agoYeah I mean I wasn't doing things like this. I was constantly frustrated because I didn't have any resources to achieve the things I wanted. Didn't even have a half decent computer. I had some janky celeron thing that barely functioned and I couldn't even buy books about subjects I wanted to learn. To think the things I could have done if I was a well off kid.
- dc3k 2y agoi'm playing around with your onshape document and learning a lot of things for my own projects. thanks! (also, amazing work of course)
- doubleorseven 2y agoDear @Lenovo Please hire this guy to help you make the thinkpad's keyboard to do wireless magic with the trackpoint and the mouse buttons include. Thanks
- system2 2y agoFYI, none of my engineer friends in the U.S. can pull this off. This is truly impressive.
- bjarneh 2y agoThis is what we come here for!
- ritonlajoie 2y agoOP you are incredibly talented. I believe very few people on earth could do something like that at your age and deliver. Congratulations !
- swiftcoder 2y agoMad respect for this build. That's well beyond what many professionals in this field are willing to attempt
- wickedsight 2y agoJust opened Youtube and your video was on top of my home page! I will watch it later today. Congrats on the awesome project! Actually, I think 'well done' is more fitting since this must have taken a ton of work and willpower!
- _joel 2y agoAstounding, well done.
- jokoon 2y agoSo if you want to install windows on this, do you have to add some secure bios feature? Is it possible to have access to that without big license fees?
- wizzwizz4 2y agoYou can just patch Windows to remove the check. It's not like any critical components of Windows are encrypted.
- itzami 2y agoThe project is outstanding but the fact that you've documented everything AND did a video about it speaks volumes about what you'll achieve if you keep at it
- deleted 2y ago[deleted]
- KeplerBoy 2y agoSuper cool work! One question: How much does JLC want for such a low volume cnc part of reasonable complexity like the laptop shell?
- martin293 2y agoI might have missed it but how much did this cost in total?
- rcarmo 2y agoPretty awesome. As someone who deals with Rockchip stuff a lot, I am going to take a look at the software part for sure.
- 0x38B 2y agoThis is one of the coolest, most inspiring projects I've seen anywhere - wow! Seeing you and nrp connect here in the comments was so cool; just the start, I'm sure. --- It was neat to read through the progress log (1), which begins, > "It was around 1AM. I wrote up the mission goal (2) and went to sleep at 2AM. The start", and ends: > "With the YouTube video and blog post almost done, I hope this isn’t the last of anyon_e. But rather, the start of a trailblazing journey." This project is the epitome of MUREX Electrical's mission statement, "attempt the impossible": It's "impossible", a non-MUREX Robotics Electrical member might say. However, we accept it as the process. In the end, we will have achieved something others might have called "impossible". But the achievement only comes through endless, motivated attempts at the impossible.

- mchinen 2y agoThis is really one of the best things I've seen on HN in 15 years. The mixed presentation of plug and play components interspersed with EE problems and solution really helped make it more accessible. It also got me excited about the possibilities and made me realize that we we might already approaching another open architecture DIY boom. I got the sense that this is a side project, but I'm sure many have noticed that it could be a legit framework-level company. Someone already mentioned the recruiters, but also you're sure to have investors knocking. Whatever you do, please keep having fun and sharing it.
- frognumber 2y agoImpressive! Suggestion: It would be nice to include a price list on the article. This project is impressive as heck, but aside from being intellectually out-of-reach for most kids, it would be financially challenging as well. Last I looked, CNC aluminum blocks were well out of the reach of 99.9% of kids (but that was decades ago; perhaps prices went down). For people wanting to follow in those footsteps, it'd be nice to know which things cost $5, which $50, $500, or $5000. Just that kind of intuition is helpful.
- dmoy 2y agoLooks like the cnc milling was done by a shop - jlccnc.com So there's probably a price there, but it's probably well under $1k Price list would be cool to have
- pl4nty 2y agoit's not as expensive as it looks, if you don't count time. CNC alu and the display would be the biggest costs. other carrier board projects use 3d printing over CNC, but the display/bandwidth is kinda what makes this novel so a lower res wouldn't make sense really hoping Byran's excellent writeup helps encourage others. SoMs have lowered the barrier to entry and birthed a ton of SBC/carrier communities, but most of their tribal knowledge is buried in discord servers
- rothos 2y agoAmazing work. How much did it end up costing?
- intelVISA 2y agoNicely done, huge amount of grit and craftsmanship.
- honeybadger1 2y agosome people just have what it takes and all you can do is watch and appreciate. really awesome!
- ValdikSS 2y agoHow is the idle power consumption of RK3588? I bet it's pretty high, I'd expect more than 1W. I have a board with old MT6572, it idles at 270mW with working CPU, even less when in semi-sleep (turns off CPU and wakes up every half a second).
- megous 2y agoHere are some numbers from Orange Pi 5 Plus: https://xnux.eu/log/088.html https://xnux.eu/log/088.html 2.4W – idle That's from early upstreaming, and for the whole board. But I can't imagine it being much lower these days.
- ValdikSS 2y agoBy the way, you can tune boot times further. My print server board boots in 8 seconds to Debian 12 (bootloader + kernel + userspace). 1. Make sure the bootloader (u-boot) loads the kernel as fast as possible. - Disable automatic Ethernet/USB/other subsystems initialization (you can keep them enabled, just don't activate unless requested in the shell manually by the user) - Tune `distro_bootcmd` command - Make sure that MicroSD/eMMC/SSD works full-speed (with proper clocks and speed protocol) 2. Use fast decompression algorithm for the kernel and initramfs - It's either zstd or gzip 3. Collect boot file access data and sort the files on the filesystem - The benefit in near-linear access & read-ahead I'm pretty sure that the current 20 seconds could be shrunk down to 14 or so.
- megous 2y agoPinebook Pro boots in about 10s to DE and that's RK3399. Pretty sure RK3588 can boot even faster, considering the advantage of PCIe/nvme storage that can run at > 3GiB/s. Software load times stop being a constraint at those speeds. My Orange Pi 5 Plus boots to sway+firefox already open in about 15s and a lot of it is waiting for net being online. 7.125s systemd-networkd-wait-online.service
- sebastiennight 2y agoWent all the way through the article to be surprised at you saying: > I ran out of time And then realized this was a ... high school project!? Way to go, amazing work!
- miunau 2y agoExtremely cool project and congratulations on having the mental wherewithal to see it through, and in such short order!
- ekunazanu 2y agoThis is some seriously impressive stuff.
- forinti 2y agoThat's impressive. I'd be really happy with myself if I just built a case and put off-the-shelf components in it.
- Atreiden 2y agoUnbelievably impressive. Such a wide breadth of skills and expertise needed to pull this off. And the final product looks great! Kudos to you!
- throwaway58670 2y agoWhile this is impressive, how come you can't make your website scroll without stutter?
- snickmy 2y agobecause the guy spent more time shipping the product than iterating on the website that describes the product. (Deadly sin of every startup wannabe)
- apricot 2y agoHeck of a high school senior project, my hat's off to you.
- mkesper 2y agoThanks to the work of the community the RK3588 is also on the right track regarding mainline support, severly reducing the fear of turning into unmaintained kernel hell. https://gitlab.collabora.com/hardware-enablement/rockchip-3588/notes-for-rockchip-3588/-/blob/main/mainline-status.md https://gitlab.collabora.com/hardware-enablement/rockchip-35...
- engineer_22 2y agoAwesome work, the future is bright
- phlipski 2y agoSuper impressive!
- numpad0 2y agoMy vocabulary hasn't got appropriate compliments - so I'd just say congratulations to the author, you've got serious talent, hard earned skills, and great mentors. Just commenting so I can't come back later and claim I wasn't stealing lots of ideas from the author for my own project; the hinge problem, keycaps, the mainboard designed on KiCAD, are all interesting.
- lr4444lr 2y agoFantastic work. How did you learn all of the EE and low level programming needed to pull this off?
- alisonkisk 2y ago> > Thank you to the Phillips Exeter Academy Science Department for supporting this project. This is what can happen when you live on a campus and don’t waste your life commuting.
- myheartisinohio 2y agoCool project. Keep building!
- WaitWaitWha 2y agoWell done! Mental note, a commercial laptop of similar specs should never cost more than $4,673.81.
- oofbaroomf 2y agoThat was the R&D cost. According to OP, the cost of building one of these is around $1500.
- cjbgkagh 2y agoI'm honestly rather envious. I guess my 'sour grape' is that the lack of funds and opportunity for me to do this is what lead me to go into software and then on into Machine Learning which I do think turned out for the best. Making electronics like this, while still difficult, is far easier than it used to be and I do enjoy it as a hobby in a way that I probably would not have as a career. It is no doubt an incredible achievement. I don't like the 'anyone can do this' when that clearly isn't true - it comes across as a humble brag and seems to be a strong part of hustle culture. I would much prefer 'anyone with a decent amount of money and a high enough intelligence can do this', or 'this is now far easier to do than it has ever been'. I do like the idea of MIT being a beacon to the best and brightest and I do think that the lack of a level playing field means that many otherwise talented people miss out on that opportunity. Perhaps what I would really like is for the world to have more MITs but I don't know if that is possible and I worry that attempts to do this would undermine the quality of MIT. So perhaps I should be content that MIT exists as is and that some people get to go there even if I did not - we all benefit from the fruits of their labor. My university was a top tier university renowned for harsh grading and I was still rather disappointed by the quality of my peers and I worry that the quality at universities in general has since declined further. Cheap and high quality small batch electronics and hardware fabrication is rapidly changing the world in a way that I think few people understand. It used to be that you had to have a decent size company to do this kind of stuff and that company needed capital investment, layers of management etc. So the cost of bringing a widget into the world was really expensive, risky, and took a long time. The only way to make that money back was to do things in bulk and sell a lot of them which meant you had to be sure there was a sufficient target market. These days a single person can design and fabricate a single item for comparatively very little. And if they want to make it accessible to the rest of the world there is no need to build a factory, just upload the plans. If it's a popular design in all likelihood someone in China will produce it in bulk at commodity prices. The speed of commodification has become so fast that it's practically instant. There is a bit of a phenomena going on at the moment with 'high tech overproduction' where it is claimed that China is intentionally over producing high tech goods to undermine Western markets - it's my view that they're ahead of us on the commodification curve. As manufacturing also manufactures the manufacturing tools the commodification process is a self reinforcing cycle.
- Havoc 2y agoAlso the 3588 chips can run LLMs on the NPU. Not quite llama.cpp level easy but definitely doable. For 7B class models the speed is usable
- mlepath 2y agoThis is an awesome project! Thanks for taking time to document this. What's next on your plate? How do we follow you?
- stevelacy 2y agoThis is amazing, love the ESP32 watchdog controller. Had a question about the keyboard - would it make sense for the keyboard to be hardwired to the laptop via USB-C and detachable to have one battery source?
- ysofunny 2y agoI only would regard this as from scratch if they smelt they own foundry
- redbell 2y agoI hardly know where to begin! This project is exceptional in every sense—a true masterpiece. Remarkably, its creator is still in high school, yet he’s already demonstrated brilliance beyond his years. The endorsements he’s received, the connections he’s begun to forge, and the incredible opportunities now within his reach are nothing short of extraordinary. As he himself put it, accomplishments like these are only possible when you believe deeply in your vision and persist relentlessly until the finish line. None of this would have been possible if he had given up before completing this remarkable work of art. It’s posts like this, fueled by incredible community support, that make Hacker News not just great but unmatched. With 2,000 points (and counting), this Show HN is currently ranked as the 4th-best Show HN of all time. If we exclude the #1 post (this upvotes itself)—which isn’t a true project—this post would be the 3rd-best of all time. Who knows? By tomorrow, it may surpass 2,741 points and claim the #1 spot outright. Outstanding work, Bryan. All the best.
- byran 2y agoThank you redbell! It truly means a lot. I'm incredibly grateful of the reception and the support from everyone. HN <3
- hn_throwaway_99 2y agoI'll just echo the amazement and congratulations of all the other comments. I do have a question though - your post stated "The hardest class I’ve taken so far was quantum mechanics in my junior spring term." Kudos to your educational system that allowed you to take quantum mechanics as a junior in high school - it looks like it clearly provided you a framework that allowed you to excel. Without giving away your privacy, is this some sort of special program where you live, or is it a standard opportunity? Again, just gobsmacked by this entire project.
- cbmamolo 2y agoHe goes to Phillips Exeter Academy, where Zuckerberg once matriculated. Students' voices are heard through the Harkness method of teaching. There is plenty of opportunity for students to grow curricularly (e.g.,dynamic chaos theory in math, senior projects, though not required ...) and extra-curricularly (e.g. competition robotics, physics, bio,chem clubs, etc ...) which may not be a norm in most public or even private schools.
- NooneAtAll3 2y ago> runs +7B LLMs +7B means "additional 7B" if you want to say "more than" or "at least", you say "7B+"
- CYR1X 2y agoObviously super cool and kudos like everyone else in here. Feel like you could make a pared down version of this with commodity parts outside of the chassis if you aren't going for a flagship competitor. I guess you could also just buy a $20 chromebook, too. Maybe...you could fit a nice rockchip SOM inside a chromebook??
- jagermo 2y agowow, this is way more awesome than I could have thought. Very well done.
- juhanakristian 2y agoWow I didn’t even know this was possible.. some people are just on another level.
- LeFantome 2y agoBuilding the laptop is impressive given his age. I would be hard pressed to duplicate this feat even with the time and money to allocate to it. Honestly though, I think the maturity shown in his write-up impressed me even more. Inspirational.
- gsuuon 2y agoI was impressed this is open source, then impressed it was done by one person, then impressed it only took 6 months, and eventually somehow impressed again that it was a _high schooler_. My mind is blown. Kudos for managing to do something insane like this. Very inspirational.
- dishsoap 2y agoWhat in the world, almost half of the comments here spelled his name wrong.
- dang 2y agoYou're right! I hadn't noticed that until you pointed it out and I'm sure most readers didn't either. Hopefully Byran doesn't mind that glitch in this otherwise rapturous and justly triumphant reception :) I feel like this thread is helping HN to reorganize itself around its proper purpose.
- posed 2y agoDude this is great, you not only build a cool thing, but also you know how to preach about it! Very proud, hope you do great things. Don't let the spark die.
- makerdiety 2y agoHopefully this new hardware development framework you just released can help me avoid being spied on by the National Security Agency's Tailored Access Operations gang and other scary creatures. True, if you have nothing to hide then you have nothing to fear. But I intend to build a billion dollar company that can fit entirely on a laptop (AI models are my employees). I don't want the pesky U.S. government or other bad hackers being privy to my advanced technology and corporate secrets. Thank you for your service to the free and open source principle. Richard Stallman and Eric Steven Raymond would be proud.
- binary_slinger 2y agoIs your mainboard the same as the CM3588 carrier board [1] that has been re-layout to match the form factor you wanted or did you have to make other modifications?

This may not have been the motivation, but I'm honored at your resiliency, lol. You never cease to amaze me! Keep going!

- asdefghyk 2y agoHow much of the laptop is open Source. How about the embedded software? Probably not. This is OK as I understand this project is a huge achievemnt. Thank YOU I've always thought it would be good for hard drive software ( embedded software on the actual drive or SSD ) to be open source. My thinking on such a situation is such a project could start with a storage device from maybe 5 years more more ago - as in my opinion the software would be a less technological challenge. (( I mean take an existing already manufactured working storage device ( ssd or hard drive ) and replace the embedded commercial software with open source software. This would remove the technological barrier of actually constructing the hard drive hard. ))
- byran 2y agoYup, all the software except the blobs for the SoC, display FW, and trackpad FW (since it's COTS) are open source! If I wanted to have those open-source, the entire machine would take a huge performance hit. I think of striking a balance. The entire linux install is OSS, the keyboard is in ZMK, and the EC firmware is written in Arduino.
- badmonster 2y agosuper cool
- jpcom 2y agoThis is amazing and I applaud your efforts. Perhaps the age of truly owning your peripherals, inside and out, is upon us.
- juliangmp 2y agoExtremely impressive work! I'll keep an eye on this, building my own laptop sounds like fun, provided I can get all the parts for reasonable prices here in Germany
- drumhead 2y agoAbsolutely brilliant work. For an individual at high school to make something like this, it's an epic achievement. Gives hope to us all.
