An open-source laptop that’s more DIY fantasy than a viable business.

Show HN: I made an open-source laptop from scratch
I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success
– Nikola Tesla
It’s got a 4K AMOLED display, a Cherry MX mechanical keyboard, plays Minecraft at 4K, runs +7B LLMs, surfs the web, and has ~7h battery life. All open-source.

The writeup below pretty much abridges the video above.
See the progression updates from the development journey here.
Imagine a skill-chart of qualities of technology: screen, audio, performance, build, tactility, touch-interaction, efficiency, size, and so many more. At the balancing point of all these qualities is the laptop. To that end, let’s build a laptop that hits as many qualities of a modern commercial thin & light laptop—while trying to do as much from scratch as possible.

I first made a mental map and transferred it into Obsidian:
Boiling it down, it landed me with a lofty list of goals:
RK3588 SoC Motherboard
CM3588 -based
USB-C USB3.1 Gen 1
PCIe Wi-Fi/BT + SSD
Powertrain
ESP32-S3 embedded controller
~60Wh Li-ion battery pack
Peripherals
Wireless mechanical keyboard
Glass-topped multi-touch trackpad
4K AMOLED 13.3” display
Anodized aluminum CNC chassis

Choosing the chip
I looked towards single-board computer SoCs, as board manufacturers commonly release schematics for reference. In many aspects, the Rockchip RK3588 is the fastest consumer-procurable chip on the market. Despite the spotty software support, the hardware documentation has lots of developer resources and reference schematics from SBC manufacturers.
Some quick specs:
Quad core A76 and quad core A55
Mali-G10 GPU
6TOPs NPU
8K@60FPS decoder
I/O: 8K display, dual USB3.1, PCIe 3.0 x 4, HDMI2.1/eDP 1.4, etc.
With only a few months to work on this project, an SoM (system on module) like the Raspberry Pi CM5 presented the best option for its hardware compatibility and a high likelihood of a snug integration. Choosing an SoM also alleviates memory and other high-speed signaling concerns. Looking around for a RK3588 SoM, I came across the CM3588 by FriendlyElec. Cheap, well-documented, and easily procurable. Sounds good!

Display
I hopped on panelook.com and filtered by size and resolution. I’ve always been a sucker for high pixel density, so I went with a 4K AMOLED 13.3” display. Cross referencing stock availability on Taobao (Chinese domestic Aliexpress), the ATNA33TP11 seem
The roast
Your ambition to create an open-source laptop is commendable, but the market reality is brutal. Competing against giants like Apple and Dell with a one-man team (q13=solo) and no funding (q14=no_funding) is a recipe for disaster. You're targeting a general consumer audience (q5=general) with a product that’s far too niche and complex for mass adoption.
Additionally, the lack of a clear revenue model (q7=one_time) and undecided pricing (q9=undecided) are glaring issues. The tech specs might impress a handful of DIY enthusiasts, but it's not enough to sustain a business. The biggest unknown (q15=will_pay) is practically shouting that you have no idea if anyone would actually buy this.
The hardware space is already saturated with well-established brands that have economies of scale, brand loyalty, and extensive R&D budgets. Without a unique selling proposition or moat (q11=none), your chances of success are slim.
Red flags
- q13=solo
- q14=no_funding
- q15=will_pay
Verdict
This project is more of a passion project than a viable business; pivot to a more manageable niche or find substantial backing.
