Key Takeaways

  • Open Hardware Manufacturing: Building a 17.5mm thin laptop with replaceable CPU, RAM, and all components disproves the industry claim that integration requires soldering parts permanently. Every capacitor, resistor, and trace was hand-selected and routed, proving repairability doesn't sacrifice form factor.
  • Display Protocol Engineering: Embedded DisplayPort required two months of debugging without expensive oscilloscopes. Success came from shortening trace distance by millimeters and eliminating one connector adapter, demonstrating signal integrity matters more than complex software fixes at high frequencies.
  • System-on-Module Strategy: Using the RK3588 SOM instead of implementing CPU directly saved thousands of engineering hours and provided known-working baseline for debugging. This approach lets solo developers achieve results typically requiring teams and millions in equipment within realistic timeframes.
  • Battery Management Architecture: Custom ESP32-based embedded controller runs state machine firmware checking charge levels, temperature, and USB-C power delivery every few seconds. Hardware iteration takes 7-10 days for PCB shipping, making software debugging first essential before committing to board revisions.

What It Covers

Byron Huang, a high school student, designed and built Anyon, a fully open-source laptop with custom circuit boards, wireless mechanical keyboard, 4K OLED display, and CNC aluminum chassis in six months.

Notable Moment

The project cost five thousand dollars in research and development but produces laptops buildable for fifteen hundred dollars in parts, demonstrating that individual makers can achieve results comparable to billion-dollar corporate research budgets.

Episode Transcript

Byron Huang is a full stack developer who recently made headlines in the hackerspace when he created the Anyony, which is a highly integrated, open source laptop. The effort was a massive undertaking and showcased great design, hardware, and software. In this episode, Byron joins the show with Gregor Vann to talk about his work on the Anyanni laptop. Gregor Vann is a security focused technologist, having previously been a CTO across cybersecurity, cyber insurance, and general software engineering companies. He is based in Singapore and can be found via his profile at van.hk or on LinkedIn. Welcome, Byron. Thank you for having me, Gregor. It's an honor to be here. Yeah. So very excited to have you here. Basically, you put out a Hacker News post a few weeks ago that kinda blew up big time about the project we're gonna be speaking about today. Mhmm. And you also put out an amazing video about it, which we'll maybe get on to. I think what struck me the most was the fact that I looked you up on LinkedIn kind of after that post, and I thought you were a teacher at high school. And turns out you're a student at high school. Is that right? Yeah. That's right. Yeah. Yeah. Which was just kinda blew my mind. So let's get into it. Could you describe what is AnyOnE? Yeah. That's a great question, Gregor. And I'd like to first describe the mission of it. It's a project that tries to show that anyone and hence the name anyon underscore e if you combine it all it spells anyone. That anyone can build a laptop themselves and it doesn't have to be something that you have to go out and buy. Of course, feel free to go out and buy one and you're gonna get higher quality, higher performance, and something that you probably use on a daily basis. But I wanted to show that people, a maker enthusiast, if you put in the effort and you put in the energy and the research, in a few months you can create something that you can hand off to a family member or someone who's not very familiar with technology and they'd be like, yeah this is a laptop, something that they can use on a day to day basis. I'm not really targeting gaming or AI or anything like that. I'm just targeting like a nice solid laptop that people can use while not really having any quirks or anything like that. And just having this machine that everything is built from scratch. There's no secrets behind the hood and that was the mission where I try and make everything from scratch as much as possible while achieving as high performance and resembling as close to a modern thin and light laptop as I could. Amazing. Yeah. You mentioned both in post you've put up and the video, you were trying to disprove the idea that technology is either …
