Hello Dangerous Thing’ers!
I’ve kept an eye on dangerous things for years. I work in software, and visit local hacker spaces for project resources and to delight in other minds.
I’m interested in getting implants. I’ve found the wiki intro thread, and purchase feature matrix of some help, in general familiarity.
I’m interested in NFC, (payments, maybe), probably dual-band access control, developer friendly/re-programmable chips. URL and vCard embeds look like nice tricks. And a bio-magnet seems essential to me.
I’ve been wishing for (looking for, but no longer expecting to find) chips that can be switched dead/non-responsive by default, e.g. toggle by pressure or squeezing. @anAndroidIdeally mentioned chips with LEDs, and I’ll direct my research there for related capabilities.
I’m interested in design, fabrication, firmware, and programming of the chips, and will dive into learning about that in a few weeks or months, after I’ve adopted implants.
Sooo you like it techy yeh? You could be interested in the DF2 chips.
And you’ll love the VivoKey Apex once it comes out.
LEDs can be put on every flex implant (fingernails), but theres also a glass LED that you can inject next to other chips. And theres the xSIID, LED + chip.
Payments are rough… read more here:
I have talked to amal about invivo buttons, so idk, might be “just around the corner” after all the Titan/Apex stuff is done. Amal has many nice ideas and even some patents!
Surely there will be much epic stuff in the next couple years.
I guess I could check Digi-Key or similar for existing examples, temper my hopes and expectations. It could have internal mechanics, linear or rotational, otherwise it would need to be active electronic, right?
Do you think magnetic/inductive coupling could work for active powering. Isn’t there a recent thread suggesting a bracket for active powering?
Definitely catches my eye.
Are they added under the polymer layer?
“Next to” as in “no spacing requirement” or “inductively powered by through flesh-gap”?
Oh I see, @amal does the manufacturing. “Customer gets what the customer wants”-customization. Hmmm.
I absolutely hate Java.
Yet… Javacards are the only current option for doing these… hencefoth the only acceptable use-case for Java in the modern days.
There are so many cases where Java is literally the worst possible choice of a language, yet the lead engineer chooses Java solely “because I know how to do that in Java, so it is the best”…
That just drives me nuts!
Anyway… I would say Javacard is to Java like Java is to C#… basically the same language, but not really.
Not sure what exactly was the question here…
Active powering… as in charging something beyond the chip?
Think my confusion comes from…
Since the chips are always passive, they will always become charged through the magnetic coupling. (re-explaining thinking of other newcomers coming here with no basis at all)
So… did you meant using the magnectic coupling to power an internal mechanic switch?
If so, I would be concerned that such a switch would be rendered moot. Since every time the chip can be read it becomes unlocked, and when it cannot it would become locked.
but there are some magnectic switches which could turn a chip on/off (none that I saw actually working with a chip, but it’s technically feasible). and they can be turned on/off by waving a magnet (which you will probably implant into a finger in the other hand)
“Next to” meaning that they need 5mm apart, but that’s just for physical safety, to avoid the implants banging together (would be bad for the implants + bad for your flesh in-between).
The xLEDs (the glass LED mentioned) are completely separate with their own normal antenna, they aren’t powered through the flash gap or anything. They just act like a separate implant, but people usually put them next to another implant.
Especially if put next to another glass implant, in the same orientation, it can act as a field orientation guide, helping you find the right positioning for the actual RFID implant next to the LED.
I would be careful planning an implant that is switched magnetically with a Reed switch or Hall effect sensor. The magnet would mess with any antenna tuning and cause inconsistent reads, as well as your finger with the magnet physically getting in the way of good positioning.
Why do you need an implant that can be “switched off” if it doesn’t have an internal battery? Seems kind of silly, because the presence or lack of a field is a natural on-off switch.
