Over the past few months I’ve been experimenting with how small a functional bearing-based mechanism can get while still feeling smooth, durable, and useful. This project started from a simple question: How thin can a real, free-spinning bearing be while still handling continuous rotation? Most “spinner rings” you see online cheat by simulating rotation — there’s no real bearing, just loose tolerance metal sliding on metal. True micro-bearing rotation needs precision, tight tolerances, and high surface finish, which is difficult when everything needs to be wearable on a finger. So I tried to…

Hi all, hope someone enjoys (or not) my weekend project. See how many matching pairs you can find in two minutes. This is written in C++ and built to WebAssembly with Emscripten. The code is at https://github.com/0xf00ff00f/rotator

Long time reader, first time self-promoter. I'm a bicycle mechanic that figured I could make the process of bicycle wheelbuilding faster, more accurate and more satisfying. I do it by sampling digital indicators, rendering the data in useful ways, and injecting domain-specific insights. The UI interaction happens by foot pedal so my paradigm retains the traditional way of working with your hands.

My motivation was pretty simple: every “spinning ring” I tried felt a bit fake. They don’t actually spin — not like a real bearing. So I wanted to see if I could make one that truly does. At the end of the day it’s still just a ring. A small, minimal piece of jewelry. But it happens to hide a tiny bearing that can hit around 800 RPM with a single flick. That contrast is what makes it fun. The way I think about it is this: it’s like a normal-looking car that quietly turns out to fly. Nothing loud or showy — until you decide to reveal what it can actually do. If you’ve used a good fidget…

While studying Geometric Algebra I have built some interactive visualization to demonstrate how geometric transformations (rotation, scaling, translation) can be constructed by just composing reflections. Accepting reflection as the most elementary geometric operation was an eye opening moment for me. I think some of you might enjoy the interactive visuals.
