Show HN: A 2mm micro-bearing ring that spins like a real fidget spinner

9•xtafnuihc•2mo ago
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 spinner for focus or stress, the feeling is similar. This is basically that experience compressed into a silent, smooth, 2mm-thick ring you can wear without thinking about it.

The D20 idea grew out of that. It’s not the main point — just a side effect of the spin being clean and consistent.

The reactions have been funny. As a ring, some people say it’s “too plain.” As a fidget spinner, it’s “not extreme enough.” As a D20, it’s “not official enough.” That’s what happens when something lands between categories.

To me it’s simply a pared-down version of all three. If I wanted something louder, flashier, or more decorative, that’s easy to explore later. This first version is about getting the core idea right: a real, precise spin inside a clean 2mm ring.

Once that foundation works, the rest — styling, variants, whatever comes next — is straightforward.

Hope that gives a clearer sense of what I was trying to do.

Honestly, as someone who plays a lot of solo TTRPGs, this D20 ring is surprisingly practical on the go.
xtafnuihc•2mo ago
Make a lot of sense, thank you
formerly_proven•2mo ago
YSK that the video can't be watched without a Vimeo account.
TD-Linux•2mo ago
Specifically, it needs an age rating set or it can't be viewed in Europe without an account.
vladde•2mo ago
looks sick. website says it's open for pre-orders, but it's not?
fulafel•2mo ago
Vimeo link is paywalled.
cracki•2mo ago
Not "paywalled". They just want you to log in. This costs nothing. Not does the account registration.

The solution seems to be to have the video "rated" in some way. Or host it elsewhere.

You pay with your data...

need help with your site?
xtafnuihc•2mo ago
Are you serious? I really need some help with my site. I’m building a web-based “spinning game” controlled by a physical bearing ring: the ring spins, and the browser game reacts in real time (WebSocket input + visual UI). I’d love to get your thoughts on the technical side. Would you be interested in taking a look?

It looks like this user here - https://news.ycombinator.com/submitted?id=spinity - has created a new account to continue spamming posts about their fidget spinner.
