Projects

Things I've built, hosted here and elsewhere.

01

Engineering

CPU Fan Design

A 120 mm PC fan designed from scratch with an AI agent: CAD, drawings, airflow simulation and renders. Then a friend's push-pull CPU cooler through the same tools.

A House, Designed End to End

A complete single-family house on a real New Hampshire lot, designed by an AI agent: every stud, every nail, every wire and pipe sized to code, plus EnergyPlus, drawings and renders.

02

Writing

How we got AI to not suck

What an LLM actually is, why agents work so much better than chat, and how to build the factory around them.

AI assisted engineering for dummies

A practical guide for engineers who don't write software. Worked example: designing and simulating a PC fan.

03

Apps & toys

MOLTEN

An abelian sandpile automaton in three.js. Drop grains, watch avalanches.
