I design and build things. Mostly software, sometimes furniture, and a few small buildings once.

American in Amsterdam.
I CNC'd myself a bed. Details, along with musings on a constraint programming language, NYC, and battery-powered air handling in my latest newsletter: kevinlynagh.com/newsletter/2...

Why I shop via print catalogs in 2025: kevinlynagh.com/catalogs/

Web designers: Our drop-down can't show more than five things.

Print designers: Here's the entire product family in one table, how the table works, and how it relates to the physical packaging.

I'll pick up that project again soon now that I've moved into my new apartment. The factory I ordered these custom springs from is also eager to hear how things are progressing.

3M's Versaflo powered air respirator is the most comfortable integrated eye/ear/lung protection for woodworking, but it starts at $1650. So I just bought the helmet for $225 and threw together the rest for $50 with a bit of 3D printing. kevinlynagh.com/papr/

Find someone who cares about you as much as Apple cares that AirTag holders fit perfectly.

Reading about superellipses and ran into an offhand reference to "squigonometry". I assumed it was a joke, then I found the Wikipedia page and a Springer textbook. I still can't tell.

Me: I wonder how DIY keyboards are going since I goofed with them during the pandemic? (kevinlynagh.com/keyboards/)

Them: We compiled a BRep CAD kernel to WASM so you can generate complex keyboard geometry in your browser. Also you can scan your hands using computer vision. (ryanis.cool/cosmos/)
