I designed and ordered my first small auxiliary PCB for work. AI accelerated circuit design and production preparation, but connector sourcing and validating the board in the real world still required careful manual work.

My First PCB Prototype with AI: The Connector Was Harder Than the Design

ThunderScope is an open-source oscilloscope that streams four channels of 1 GS/s data to a PC in real time over Thunderbolt, USB4, or PCI Express. This article explores its PC-based display and processing architecture, the ngscopeclient and TS.NET software stack, multi-unit synchronization, and the potential for custom gateware.

As supply-chain risks grow around InP and InGaAs-based materials, not every SWIR application necessarily requires an InGaAs sensor. Below 1,100 nm, silicon-based BSI CMOS can be a practical alternative in terms of cost and supply stability. This article looks at the technical boundary between InGaAs and silicon.

Starbucks pulled NomadGo’s computer-vision-based inventory management system just nine months after rollout. This case highlights the limits of marketing claims like 99% accuracy, the constraints of FOV and on-device AI, and the difficulty of simply adding vision technology onto existing store operations.

Why Did Starbucks Give Up on Computer Vision Inventory Management?

A recap of visiting Shanghai Vision China and Semicon China 2026. The shift toward edge devices by Chinese companies, the overwhelming scale of Semicon China, and the vertical integration of materials, components, and equipment made the speed—and the urgency—of Chinese manufacturing feel very real.

Vibe coding makes it seem as if anyone can build software now, but beneath that promise lie new constraints: token costs, platform moderation, market concentration, and relentless quality competition. This essay looks at the future of vibe coding from both optimistic and skeptical angles, and argues that what we really need is not a fantasy of easy money but the ability to adapt to the AI era.

This is a text that helps you understand registers, memory, ALU, flags, branching, stack, and assembler while directly implementing a 16-bit CPU in C code. It is especially recommended for those who want to connect computer architecture not through abstract explanations but through working code.

What does the CPU think? A great introductory article on building a 16-bit CPU directly in C.

Dutch AI semiconductor startup Axelera AI has secured an investment of $250 million. This news goes beyond simple funding; it reaffirms the presence of European AI semiconductor startups and the growth potential of the edge semiconductor market for AI inference. I summarized why Axelera AI is gaining attention and what this investment means for the industrial AI and machine vision sectors.

Axelera AI's large investment attraction: Reasons why European AI semiconductors are gaining attention again

With AI-composed concentration music overflowing in YouTube work playlists, a sense of 'familiar yet unappealing' fatigue has emerged. As this happens, channels that create song selections and videos manually become even rarer. Even in an era where anyone can create, there is a clear reason why certain content gets chosen.

Reading Adrian Li Mow Ching's Father's Day Q&A on Clicks Blog made me rethink the meaning of 'securing time.' Time is not something that is left over; it must be secured. These days, I have been prioritizing handling over planning and living reactively. Through the perspective that parenting and leadership are similar, I reflect on the attitude of 'bystanding' and intend to start implementing small routines again.

Parenting and business, ultimately 'securing time' is essential.

Unlike the macro trends in AI news, 'Moltbook,' derived from personal-based agent projects, is a community where AI agents interact through posts and comments. The continuation of conversations, trolling, and tip-sharing resembling human communities is intriguing, but it also evokes the imagination that the 'dead internet' could become a reality.

Yuval Harari, having accurately understood LLM as a 'language token-based probabilistic model,' poses a more important question: 'What is Thinking?' As language begins to be replaced and dominated by AI, laws, religions, books, and cultures could be restructured. He also warns of the potential for 'AI Immigrants' to flow in without borders, rapidly changing job and power structures.

What initially felt like a barrier to entry, Markdown has become the basic syntax for communicating with LLMs through notes, development, and blogs. We learn again from the history of Markdown the core of product development: precisely defining simple inconveniences and solving them in an even simpler way.

Two key points of product development that Markdown has taught us

The LSSTCam is an observational camera with 3.2 gigapixels, 189 sensors, and processes tens of GB of data per second. This article briefly and clearly summarizes the key specifications and structure of the LSSTCam, explaining why it is called the 'world's largest camera.'

A field issue occurred where serial communication between a PC and an Arduino
became unstable at a distance of 3–4 meters.
To resolve this without modifying the existing host application,
a Raspberry Pi was introduced as a relay server using a Gigabit network
and virtual COM ports.
This post describes a practical, albeit inefficient, workaround for urgent situations.
