- Embedded Dev LLM PCB Routing: Turning a Human's Fixes Into Rules
I handed a 96% auto-routed PCB to a contract engineer. He did not just connect the last 4%, and that difference became 16 rules my agent can reuse.
- Embedded Dev Per-Project AI Agent Harness: Side vs Production
I run side and production projects at once, so the workflow has to differ. Most harnesses are fixed, so I built one that generates a harness per project.
- Thoughts SpotOn: How I Run an AI Team of One
Most of the first draft is written by an AI team. But the parts I have to know, and the ones I decide, I understand end to end. Read wide, write alone.
- Thoughts SpotOn: The Two Seats a Harness Can't Fill
I re-sorted the twenty-eight disciplines a hardware product needs. Twenty are files, so the harness owns them. Six stop at a doorway. Two stay human.
- Thoughts SpotOn: A Roadmap One Person Can Finish
A solo founder's roadmap isn't a build schedule. It's a map of kill-gates: cheap checkpoints before the expensive stages, and permission to quit early.
- Embedded Dev SpotOn: The Co-Founder That Builds Too Fast
The harness made building so cheap that I built almost the whole product before validating anyone will pay. The dangerous side of a good co-founder.
- Thoughts SpotOn: What I'm Building, and Why Alone
A tennis player and 18-year embedded engineer builds an impact sensor solo, with an LLM as the team. The start of a productization diary, kept either way.
- Thoughts How Long Does Harness Engineering Have?
Everything useful in a harness eventually gets absorbed into vanilla. What survives is only what the vendor structurally will not or cannot build.
- Embedded Dev What loop do I need to keep improving my software with LLMs?
Working hypothesis on whether I can wire my own project into an LLM-driven self-improvement loop.
- Embedded Dev AI-Written Firmware: How to Stop AI from Breaking Firmware
3-Tier Trust classifies PRs. Verification gates (spec, TDD, RAG, HIL, deterministic analyzer, more) take them to merge. Each catches a different defect class.
- Embedded Dev AI-Written Firmware: Where It Breaks
AI-generated firmware fails in predictable nonlocal patterns. 3 visible in diff, 3 that detonate after 49 days.
- Embedded Dev AI-Written Firmware: How Far Can You Trust It?
I asked an LLM to write a logging daemon. It compiled, ran fine, and was silently killing the eMMC. What you leave out of the prompt is where embedded AI code breaks.
- Embedded Dev AI Agents in Embedded: The Full Pipeline
Complete project anatomy for AI-agent-driven embedded development. Specs, property tests, review agents, and feedback loops on i.MX8M Plus.
- Embedded Dev AI Agents in Embedded: Context Engineering
AI agents write good Yocto recipes but silently corrupt sensor data and misconfigure SPI registers. The fix is context engineering.
- Embedded Dev AI Agents in Embedded: Spec-Driven TDD
Embedded teams skipped TDD because the cost was too high. AI agents change the economics. Spec-driven testing for an IMU driver on Yocto.
- Edge AI Hardware Docs for LLMs: grep vs RAG
RAG destroys the cross-references that make hardware docs useful. Skip the pipeline: give the LLM your SVD and PDF as file tools.
