OOPS, sorry, just found that this question was asked quite a few times before (missed to expand the comments), and the way Kay-Kay does it in the YouTube video is just that. So case closed ;o)

I don’t own a single bit of Apple product but the photos make me wonder whether you couldn’t remove the battery separately, and leave everything else in place? Besides the speaker housings that cover a small part of the outermost batteries, is there anything else on top of them?

Or is this gutting the entire base just a matter of caution to ensure the adhesive remover does not damage anything on its way?

Great pictures, but I’m missing a look inside the PSU. It looks like it could be opened rather easily. Would be great if you could share some insight there. Thanks B-)

Hi Jacco, thanks for this guide. What device is this? As the instructions for disassembly are somewhat specific, this could be interesting. For cleaning the encoder, you seriously recommend to do that using a screwdriver? I find the spring contacts inside these encoders rather delicate typically and they would easily take damage if the wrong tool is used for cleaning. I must recommend to use 1) a lot of care, 2) nothing that is tougher than cotton buds, 3) alcohol, and 4) contact spray eventually to keep things clean and coated against future oxidation. Usually there is no need for scrubbing if contacts are gold plated. Oxidation might be an issue otherwise but that is best removed with chemical anti-oxidation agents, and if that does not help, a (very) soft metal brush, or maybe very fine grain sandpaper, applied with as little pressure as possible of course. A screwdriver will easily scratch surfaces or bend contacts, both of which will cause the encoder to drop out again sooner than later.

Could be an inductor, they often come in shiny plastic cases and the coil is visible. The PCB closeup is not close enough to be sure though...

*rofl* about that eyelash controller, good one! ^^ love to see how cleverly market-ready products such as the Samsung display unit are included.

Besides a front-facing stereo set of cameras for AR, I think an eye tracker would make sense. While its output would not affect the perspective, software might make use of knowing where you are currently looking.

That product is on its best way to become a must-have toy...

You are pointing out that the ring movement is detected visually. Are there any photos of the inner side of the ring that moves past the detector? Does it have a special pattern on it to make motion detection easier, or is it just a plain metal surface?

Uhm, sorry, what about the photos? I don't see any...
