I build tools for my hobbies — mostly measurement hardware and software for RC aircraft. When something turns out to be useful, I share it.

A multi-node angle gauge for rigging RC aircraft — incidence, decalage, control throws, and differential. Two or more M5StickS3 nodes clip to different surfaces and read at the same time, resolving to about 0.01°.

Reads two surfaces at once, so the aircraft never needs to be leveled

About

Most of what I build starts as a problem in one of my hobbies. Usually it's something I want to measure properly, and the off-the-shelf option isn't accurate enough or doesn't quite do the job.

That tends to pull in a bit of everything — sensors and firmware at one end, a usable interface at the other, and some signal processing in between. I try to build things that hold up in a workshop or at a flying field, not just on a bench.
