Planning a full-body scarification by now, soooo… well… discomfort is not such a big thing, I guess 
Looks absolutely incredible, want that unter my skin! Though a ring would be more fitting for my ideas… ah, I’ll take what I can get 
edit: but I have to ask - what the hell is that? 
yeeeeeeees, exactly. Won’t put it there, but I could use a bunch of those^^
It’s a thing I found trolling around the nfc toys section of Alibaba… it basically has an LED in parallel with an led which stands 90 degrees on end and shoots into a plexi disc with an odd backing on it that helps light come out the top. It’s well over 2mm thick though… trying to figure out if it can be made into an implant.
Looks like placing a single led in this orientation is the only way to keep performance of the ntag216, which is critical in this case because my samsung galaxy s7 is quite shit at reading it… 5mm max. The pixel 2 is ok though… so I’m going to go with the worst performance and say that putting 3 LEDs on will basically be a show stopper for some phones.
Is that available as a circle as well? Because in that case, I could use the fact that it will be clearly visible (being 2mm thick) as a visual effect which would be quite fitting… but I guess probably not, because there has to be some kind of chip inside for it to work with NFC
Okay… in the picture, it looks like there is some kind of “metal”-ish ring around the thing, is that right? If so, what material might that be…? I’m highly allergic to nickel, so I’m not all too happy to implant unknown metals into my body…
But still, veeeery interesting thing!
As for the second, single-LED-blinky, looks quite nice too - has anyone experience with installation on more unusual places, like chest, shoulders, near (not directly over!) joints, whatever? I know that silicone implants over softer tissue are idiotic, because they simply sink in and are not visible - but what about these? Any idea?
it is a circle…
… but if you were asking about a ring, then no it does not come in a ring shape.
Yeah there is an NTAG213 inside.
No it’s a bit of metallic material that reflects on the inside and is black on the outside, also to keep light reflecting out the top surface and not spill out the sides.
No idea, but probably aluminum or some other cheaper metal that can be made into tiny thin reflective strips.
Okay, guess my last english lesson is to long ago… at least, now I know the difference between a circle and a ring
I was thinking up different types of flex based implants, and was wondering if this would work.
I’m not an electrical engineer, but could it help with the contraints of size and reading range? For positioning, it would fit along metacarpals or the forearm.
Yeah in short we tried something like that and it didn’t go well.
That’s unfortunate, hopefully there’s some similar alternate, not just in the grain or circle format.
