Design-wise I liked the industrial more, it was more cyberpunk. But this is very neat too.
What I find pretty crazy is that there are .65x.65mm RGB LEDs, equal to the long side of articles LEDs squared. They are also only .25mm thick, that's same as few sheets of paper. One cyberpunk look I'm thinking you could do with those is just to glue them on your face and blend in with makeup; I'm sure someone could do fancy things here. Wire you can get pretty much as thin as you possibly want.

> It's an impressive electronics project, but is it an earring anyone would want to wear?
Are you kidding me? Just about every STEM gal would pay a pretty penny for a set of those!
The industrial[0] is a bit too obscure, the led-ring variant[1] is a little underwhelming, but a full LED matrix? Absolutely breathtaking.

This is very cool and I know a LOT of people who would buy and wear these. If you productized these (possibly make them rechargeable and simply way to program the LEDs) they would definitely sell.

I ended up doodling up some ideas [1] based off this, with a pendant, OLED display, and a separate battery holder hooked to the ears coming to mind. A similar design would also be cool for earbuds and IEMs especially if the lights could be synchronized to the music.
(Seriously though, everyone should learn how to sketch the designs in their head. You don't have to be good, you just have to be adequate enough to get your point across).

I don't know if it's feasible at this scale, but a version that could optionally animate or pulse in sync with sound (music) would be a big hit in nightclubs.

Pretty cool to see 2x2 layer sandwich of pcbs. It’s going to be cheaper than 1-2-1 pcb at small scale. That’s the same thing Apple does.

I wonder what the smallest circular OLED display is. There are 01005 LEDs (the next size down from the 0201's used here) but at that point an OLED display is essentially the same thing.

At this point it seems like the biggest limiting factor of scale is the vias, not the LEDs themselves. If they made LEDs with 3 pads, where the outer 2 pads are connected together, you could make a matrix on a single-sided board with no vias.

I saw that yesterday and immediately googled if I could buy a similar led matrix for making a set. And I'm a man that has never wear any earrings and do not plan to wear some. So you can say that the marker exists

The led trails photo got me thinking you could make some cool persistence of vision stuff with these. As long as the wearer is going fast enough.

I'd like these as cuff links. Imagine it as a status symbol!
by UberFly on 2/21/24, 2:03 AM
Very cool. I could see these being popular if sold. Expect to see these on Ali or Temu by the end of the week.

The last thing anybody concerned about their looks wants is to have strong side light shining up close on all the imperfections, scars, bumps and overall messy skin that looked so nice and smooth before.
Guys really don't want to see woman's pores and pimples 3D facial structure. Or anybody's else for that matter.
by TazeTSchnitzel on 2/20/24, 10:14 PM
Very happy to see someone did this, because I had the same idea many years ago, but it seemed infeasible.

It’s always trippy to see mitxela linked here, as I primarily know him from the Halfbakery, and he is apparently one of the users who actually is capable of baking his ideas…
by Upright8905 on 2/22/24, 6:43 AM
Very nice project, very cool and really creative on the part about soldering together 2 2layer pcbs to make a poor man's 4 layer pcb x)
by imzadi on 2/20/24, 10:23 PM
Could you include ir LEDs to blind cameras? Is that a thing?
by jbl0ndie on 2/21/24, 9:19 AM
I'd be interested to see an algorithm for the blinkenlights effect he demos.
by pests on 2/21/24, 5:31 AM
I wonder how much the "staggered blind vias" PCB would have been.
by jes5199 on 2/21/24, 3:47 AM
I am impressed! It’s startling how small things have gotten
by k__ on 2/21/24, 9:32 AM
Awesome!
I have circuit plugs, LED matrix plugs would be the next level :D
by Lord_Zero on 2/23/24, 4:06 PM
Maybe should coat it in epoxy at the end

would definitely buy these!

fashion victims will fall for that.
