The price difference could be explained by LCSC purchasing in bulk directly from TI or similar and selling them at lower margins because their volumes are larger. I've seen "clone" chips sold at LCSC, but they're listed under a different brand (I can't recall one off memory unfortunately).

Hey HN, this past summer I went to NextPCB's factory and toured the facility. I asked questions from a variety of creators to factory workers at random.

Indeed! I just woke up to find that the post has got 2,742 points which officially make it the best Show HN of all time! You can see the full list here: https://hn.algolia.com/?q=show+hn
Byran, you now have probably the best C.V. you can use for any job and you should be proud of yourself.
Congratulations!
Thank you so so much!! I’m shocked and incredibly grateful. HN <3

How 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. ))
Yup, 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.

Best 5 grand they ever spent. Byran your cross discipline knowledge is amazing. Well done!
Quick question, are your parents in technology and science or are you self taught? Always like to hear about the backgrounds that create the environment for something like this to come together.
I've met amazing people throughout my journey thus far, but no. I have no background in engineering, but my parents have always been supportive. I started falling in love with it in 9th grade with keyboards + ZMK!

I 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.
Thank you redbell! It truly means a lot. I'm incredibly grateful of the reception and the support from everyone. HN <3

Really amazing and impressive work. And also an excellent resource for future explorers.
One thing I didn't see mentioned in the video is the total cost of all the materials to complete one laptop not including all the experimentation cost. I'd be super curious about that.
I have the R&D BOM in a link below [1]

If 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.
Woah! That would be amazing! I sent you an email just now. Thank you so much for this opportunity!!
