What device could be used to light up LED implant from a fair distance. Basically have a cyberpunk inspired tattoo (Jhonny silverhand arm) and want to add add LED implant that I could activate with a device from a decent distance let’s say 1 foot. First idea in mind is a custom made reader inside my shirt on the rib cage area. Any ideas ?

LED powering is actually a pretty hot topic:
Unfortunately, there’s nothing that I know of that gets anywhere near the 1 foot range you’re looking for yet
There are also some other glowy-type implants that have been brought up which may be of interest to you:

LF xLED with el cheapo wireless charging coil. We played with putting a bend in the coil (think of the coil as being on an X-Y plane now bend it so it extends onto the Z-axis) and it worked great. One foot of range is wildly unrealistic. These things are designed to work at most at a few inches.

One foot is pretty difficult to achieve.
I’ve made some small signal generators and have gotten about 3 inches pushing 9v through it but I wouldn’t recommend it.
Mid to end of November I plan to have something more user friendly out but extensive testing is needed.

New to this and don’t really know any specs or anything but couldnt something similar to what’s used in DIY perk’s true wireless power video but on a smaller scale say sewn into a jacket or something work
Hey welcome! Which video are you referencing?

This one here, Its quite cool.
I got in on the early access, but I haven’t committed to it yet.
I can see some awesome Cyborg options with their kit.
This is the company channel

I mean, they jump right into implants;
Still… receivers gotta be pretty big…
A certain little project I’m working on would require the 50x50 sized receiver and just barely cover power budget at peak draw.
Seems a pretty promising technology though, room for improvement since it’s pretty new too. Plus these receivers are standalone, you could probably get more out of purpose built coils integrated into whatever you are doing
Unlikely… the physical dimensions of the coil seem to have a direct impact on total available power. The only way it might be smaller is if 1) you required a lower voltage like 3.3v vs 5v, and 2) you could change out the voltage control circuitry so stepping down was unnecessary… then perhaps a smaller coil with the same watt output at 3.3v might be possible.
I have reached out to see about an eval kit.
Interesting, wonder if the power transmitter unit could also be purpose adjusted for better short range performance.
Possibly… but what I find interesting is the potential for 3D designs… like what if i created a multi-layer receiver board… would I be able to reduce the dimensions in exchange for more overall surface area? Perhaps… perhaps not… interesting to think about the possibilities though.
For example…
What if I put another ring inside that ring, but offset it by 2mm in the z-axis so it’s not on the same horizontal plane as the outer ring? You might be able to calculate the possibilities given the wavelengths involved.

Yeah, that’s the kind of thing I meant by purpose built coils, designed to occupy blank space around whatever circuitry. The factory receiver boards are made to be thin and flat for easier use on a desk environment, at the cost of x and y dimensions.
Couldn’t find any details about why the receiver discs are flat, if it’s just preference like I assume then I wonder how a manually wound vertical coil would fare
DM’d you
