  • Need to sleep, not going to be able to address this fully. Important note, though: Magnetic fields do not have a substantive affect on Bluetooth or WiFi communication.
  • Hey @warmish I meant to add my thoughts to this earlier, but I forgot until I saw your post on DT. I think a platinum iridium alloy would be an awesome coating for a magnet! I also think that getting a business to do the coating for you in smal…
  • I have an xG3 on the way. I'm going to have it installed in the tragus for sound transmission. I'll let you know how it goes. Keep us updated on yours. We should keep this thread going with details, because I know a couple people have been asking ab…
  • Hey @trroyyc I saw your post on DT. Here's the amplifier board that Vicarious used (Velleman PMK190) https://www.amazon.com/Velleman-MK190-2X5W-Amplifier-Player/dp/B007K2N0ZI You'll also need some magnet wire to wind into a coil. Some 20…
  • While you wait for the second batch of xG3, get some magnet wire and a cheap amplifier breakout board online and try it out. You can just put a small magnet in your ear canal. Let us know how it turns out.
  • Hey @trroyyc A user named Vicarious on the DT forums has been experimenting with that lately (not sure what his handle is on here, but he has more than a dozen implants so he's certainly here somewhere.) He used the recently produced xG3, which…
  • if'n these folks are in dire need of sex-talking biohackers. Talk Grinder to me.
  • It looks like there's a cooperating piercer at Blue Lotus Piercing in Newcastle on Tyne. That's still a ways away. I'm sure there's some UK people on here, they just might not be checking in regularly.
  • > @ThermalWinter said: > I´m not certain what you mean by the medial face, the only resembling thing I can think of is the medial antebrachial cutaneous nerve in the lower forearm so do you mind clarifying so I can be more helpful? Y…
  • @Srg I agree with @ThermalWinter. I had my flexDF installed on the lateral face of the forearm ~6cm above the wrist, and it is a tough install spot. There are a bunch of blood vessels and tendons there. Luckily my install went well, but now 7 mont…
  • @dieselpwr said: and btw the magnets used are 24k gold plated gaussboys 3x1.5 n52. they are very good quality in my opinion. What would you estimate the size of the whole magnet was after applying the PET? The silicone (and even…
  • Someone used the xG3 as a tragus implant. It didn't reject and they are able to pick up sounds with it: https://forum.dangerousthings.com/t/xg3-biomagnet-suggested-locations/3906/58
  • I had a flexDF install with the incision method. I suspect the needle method will be less painful, but there are very few public accounts of it so far. The separation of the fascia to make a pocket for the implant really sucks. It's made worse …
  • Since there is interest, I'll start another thread related to updating the Wiki. I have some experience with project management and documentation. I've been keeping up with DT and Cyberise pretty closely, so I should be able to get some info togethe…
  • > @IvoTheSquire said: > But if we are talking about making it easy to access as in "if a layman wants a magnet in their finger they can have it without going through all the tests and experimentation that the pioneers had to do", or even j…
  • The ear magnets are usually implanted in an area of your ear called the tragus. People with this implant will run an amplified audio signal through an inductive loop around their neck (looks like a copper necklace). The audio running through the loo…
  • @trybalwolf All the NFC readers with keyboard emulation that I've tried have terrible coupling with the helical antennas in the glass tags. The ACR122U is the most reliable HF USB reader I've found. There are a huge number of knock-offs ou…
  • Excellent news. I look forward to seeing how much exposure they get through the skin. I know infrared travels through skin basically unhindered, but UV not so much.
  • I mean, It seems like the use case is a lifting magnet, not a sensing one. I used a field strength calculator at 3mm distance and came up with 0.01lbs of pull force. You could lift a few paper clips or a screw with that. I agree with Cassox that the…
  • AFAIK the Ni-Cu-Ni coating with the biocompatible ones on top is pretty standard. Really, the more coatings the better, as long as it doesn't make the magnet too large overall. Someone with more knowledge will be able to tell you more, but I re…
  • Hey @Johnny3D Still working on this? I just purchased some of that Eu:SrAl2O4 glow powder and was pleasantly surprised. A few seconds of UV exposure kept it illuminated for a few minutes. I would love to try making an implant with it.
  • @trybalwolf Are you going to hardwire it, or use batteries? Also, the metal body of the safe would probably attenuate some of the field and reduce the read range. Since the safe will be stationary, you might want to situate the antenna off to the …

  • Definitely that. You just need to be selective in your choice of door strike to prevent tampering. Also you might want it to be "normally open" so you can get in if you lose power. I'm a huge fan of the HF. In this use case opening your gun sa…

  • @Dani123 I'm not telling you how to live your life, but that came across as really hostile.
  • You could use something like this reference design for communication between the implant and a phone: http://www.ti.com/tool/TIDA-00217 Put these two chips (NFC controller and low power MCU) on a 0.6mm thick PCB with some kind of convex el…

  • So the idea is to implant a thin puck of biodegradable material (like PLA) that has been impregnated with a drug or nootropic so that it can be delivered slowly over weeks or months instead of ingested every day? That sounds rather invasive. Do you …
  • Hey @tjom, good to have you join in on the conversation. I don't have a medical background, but I have some experience with implant recovery. I had an xNT implanted in that spot a few years ago. Bruising and soreness is definitely expected. …
  • Hey @Bobtheguy, Welcome! You're on the right track, but I do not think that magnet is appropriate. The biohack.me community has come to the conclusion that gold plated magnets are not reliable enough for implantation. Some of the reasons are: …
  • I had been occasionally checking in on the Grindhouse Wetware Facebook page to see what you were up to, but I much prefer YouTube. Thanks for the comprehensive update and all the work you do.
