  • I'm quite certain there is not. It appears those keys are active transmitters and run on batteries so changing them would be a pain (pun intended). You'd also have to pre-programm those keys for your car (which involves inserting and turning the key in the ignition on many car models). Theoretically you could hack apart a…
  • maybe relevant https://forum.biohack.me/index.php?p=/discussion/comment/26033
  • as for quetion # 3 i can only comment on the tiny capsule implants, usually placed between thumb and index finger (backside of the hand). It's virtually not there at all unless something presses the tiny capsule against the bones nearby. This only ever happens when you wrap a rope around your hand in a very weird way which…
  • I can confirm this based on first hand experience (pun intended). Most veterinarians are skilled enough to pull the procedure in less than a single second. Implanters with less experience might take their time but it's not that bad. Touching or bumping the implant location in the following couple of days might cause…
  • Short answer: no. While your body appears to be able to handle a piece of zinc without suffering from any severe damage. The piece of zinc will suffer severe damage from your body. Or in other words. Your body can bioerode zinc away. Therefore a zinc coating will fail, leaving a magnet exposed to your body including all…
  • First you should pick something that's of interest for you (like are you interested in magnetic implants or in electronics or whatever). Then you should get into the topic, do a lot of reading on each and everything related to your interests. And once you got a basic idea of what you want to do we can help you by answering…
  • that's not how physics and engineering work. unfortunately.
  • A magnetic coating over your bones will do nothing. No stronger bones. No stronger/faster movement. No special powers. You might be able to put a fridge magnet with sticky notes in places where your bone is near the skin. Drawbacks: you get in trouble when going near big magnets (scrapyard magnets, MRI machines, etc).…
  • ISO 7010 E003 (the white cross on green background as international standard for first aid) and the "Star of Life" (it probably is recognizeable by medical professionals). Starting from those add a few of the typical wifi lines. However I doubt that someone with medical routine will bother to download a NFC reader app and…
  • A related talk about the system you are up against. https://www.youtube.com/watch?v=z_WlOc_Kzh8 Long story short you have 3 possible levels of difficulty: 1. pretty straight forward for all cars without imobilization system. That's for cars older than about 1991 but you basically don't even need a key to start those if you…
  • no new idea about magnets other than most coatings are crap. I'm not the right person to ask if something is safe. I can only tell you why some things are not obviously not safe.
  • producing the capsules isn't even the problem. Welding them together requires laser welding optimized for very thing materials. It does exist and there are specialist companies out there but I got no response from any of them. You should be prepared to hand over some cash there. If you can drop a request as a legit company…
  • You have to put those things into perspective. You are concerned about your safety already, so your life, health and safety should be worth 60 bucks. A broken tag, glass fragments, infection, a loss of your limb or life is considerably more expensive. Those things DT is selling are purpose build and tested. You pay for…
  • Guess it depends on how many of those 100 survive the usual testing procedures.
  • Just for fun I tried to search amazon for HUD glasses. There's quite some choice. Glasses with HUD integrated are pretty dense packed circuit boards with constraints on size, volume, weight and power demand/availability. It'd be pretty hard to build non-clunky Glasses with HUD integrated from an DIY perspective.
  • I'm by far not an expert. I just read up on stuff. Given the sparse amount of information on ePTFE it seems to be similar to regular PTFE with different mechanical properties. I found no information about the differences in coating application/processing or other more important stuff like permeability to water or oxygen.…
  • You have to see the differences in application. having a solid block of material (like in most implants we talk about here) is usualy perfectly fine. If your application generates small particles (for example from joints under mechanical load) or like the felt which consists of tiny fibers, that's something entirely…
  • according to the handbook for biomedical engineering and design ( ISBN: 978-0-07-170473-1) PET undergoes very slow bioerosion. it does have reasonably good permeability to prevent moisture and oxygen (so it will most likely be unaffected by the salt water tests). you best keep an eye on the implant. On the long term as…
  • there are more than 120 posts regarding supermagnetman magnets on this board. Many containing valuable information about magnets and coatings and what's good/bad etc. If you don't feel like reading it up here's the short story: no magnet is safe to implant until proven via extensive testing.
  • I've worked with raw HDPE rods for welding before. Quite the interesting material which can be hot-melt but ultrasonic/friction/laser-welding works too. If you have two parts with different optical properties (for example one transparent in the IR-range and one opaque you can laser weld it with an IR-Laser through the…
  • i guess you could run an ftp server on an esp8266.
  • I'm not the ultimate magnet guide guy but there is a reason behind all those coatings. The Ni-Cu-Ni coating's job is to protect the magnet from moisture and oxygen. Even the smallest (read as in you won't even find that with a microscope) error/failure/pinhole/whatever will allow oxygen/moisture to attack the magnet and it…
  • getting back to solid metal for a quick question. if the moisture creeps in through inperfect grain boundaries in thin coatings, how would changing metal thickness and grain size impact the barrier performance. like would bigger grains be preferable because there is less overall grain-corner-length. Or is bigger better for…
  • as a reminder. we need a moisture barrier here. means something that prevents h2o molecules do diffuse through. a monocristaline metal or diamond would be ideal. i don't know how graphene would hold up. it might be thin but i'd say it so thin that some freaky quantum-mechanic-interaction-tunnel-magic might very well be…
  • @zerbula, yes polishing with diamond dust works but it literally takes monthes to wear down the surface even a tiny bit. it's pretty much the hardest thing you can do, sort of literally. the process i am aware of produces about palm-sized diamond disks and they require multi-kW magnetrons to keep the plasma going. so i…
  • diamond sounds nice in theory. you can grow it using microwave heated gas to create a plasma. Temperature wise i'm not sure but that's not the issue with diamond. biggest problem is, you get a very rough polycrystaline diamond surface. this stuff is virtually impossible to work with. you'll get hard crystal orientations…
  • https://www.ele.uri.edu/courses/bme181/S02/Tom_2.pdf (the stuff mentioned above) https://microprobes.com/files/pdf/publications/gen-knowledge/cogan_2008_neural_stimulation.pdf http://iopscience.iop.org/1741-2552/10/1/016007 https://freidok.uni-freiburg.de/data/7289…
  • keep in mind the demagnetization is also geometry dependent. https://www.kjmagnetics.com/blog.asp?p=temperature-and-neodymium-magnets getting up to 160°C might be a bit tricky but with a more cylindrical shape rather than a disk you could get away with minor loss in strength.
  • Could you at least provide something remotely comparable to a scientific look at this mixture before asking for bitcoins? Correct me if I'm wrong but I see a lot of "might" and "maybe" claims but no hard data. Side effects? Risks? A controll group? Measured brain activity levels? Mixing a bunch of psychoactive substances…
  • metal platings are very different from a solid and flawless metal shell. if you can't make a plating perfect there is not much reason to do it in first place. a tiny flawed spot is enough to make the whole thing fail. given the past track records filling holes with metal plating seems to be a questionable tactic at least.…
