NAND-16: a computer built from 277,248 NAND gates
An interactive browser-based 16-bit computer simulation containing 277,248 NAND gates, created via AI generation.
summary is enough The visual demo is slick, but community inspection reveals it is AI-generated with nonsensical circuit routing.

summary
The project showcases an interactive 16-bit computer built from nearly 300,000 NAND gates, fully navigable in the browser with zoomable views down to individual gates. However, commenters inspecting the implementation discovered that the circuit routing is broken, contains nonsensical terminations, and was generated using an AI model. This realization turned initial awe into widespread disappointment regarding the utility of unverified AI outputs. Consequently, the discussion centers heavily on the changing nature of hobbyist engineering in the era of generative AI.
key points
- The project models a 16-bit computer using 277,248 NAND gates, featuring browser-based zooming down to individual logic gates and SRAM.
- Technical inspection by HN users revealed that PCB traces terminate at random points and cross over each other incorrectly.
- Discussion quickly shifted from praising the visual achievement to criticizing unverified AI-generated code and 'vibecoding' culture.

discussion skeptical
consensus
Commenters initially praised the smooth browser performance and deep zoom mechanics, but quickly turned critical when technical inspection revealed broken logic and AI generation.
pushback
A few argued that orchestrating AI tools represents a valid modern form of technical production and curation.
It looks gorgeous, and you can zoom in to an individual gate level and see lines switch from high to low
The problem is the rendering is wrong. Gates which are connected to two distinct inputs according to the text description which pops up when you click on it are rendered as having both inputs connected to the same wire. It's a bit of a shame.
It bridges the gap between initial visual praise and the technical realization that the underlying circuit rendering is fundamentally flawed.
