  • No worries, your English is very good. I'm sorry you have to adapt on account of our limitations. The Titanium Nitride (TiN) coated implants have been found to develop micro cracks on the surface (it's a ceramic coating). They do last a while if …
  • Usually when my magnets have gotten itchy on a regular basis it means the encapsulation has been compromised and they're starting to corrode. Could be that before it rains your skin changes texture as you absorb moisture from the air, and you're mor…
  • What's the encapsulating material composed of? That will affect what sterilization methods are safe to use.
  • I'm also around here(ish), near Philly. The partner map on the Dangerous Things website is a good resource for finding open-minded piercers to do installs.
  • Yup, just buy the wristband. They send you the card and the silicone wristband (you can just toss the band)
  • There's no fee to load the card, but there is a $4.95 per month fee charged to the account if you spend less than $250/month. Since most users won't spend that much, it's basically a $59.40 per year fee to use the implant. I deemed it worth it, but …
  • It's not a DT magnet, it's a 3mm x 6mm N52 parylene coated one I got from a body mod artist. Personally I hate the "paperclip test" but attached is a pic. I can lift approximately 28g of steel wire. I also have an xG3 in my tragus that can…
  • Yeah, I can weigh in. I have a flexDF in that spot behind the wrist where a watch would conventionally sit. It's not a bad spot, lots of real estate compared to the hand so a spark should be no problem. As far as usability it's a good position for r…
  • > @Cassox said: > There are also a lot of people who just want to make cool shit. I am one. I've been experimenting with RF energy harvesting to power LEDs (and other things). There's a pretty convenient chip for that purpose called the N…
  • Oh, neat! What's the coating on the magnet? Mine have both been done with a piercing needle to do the incision and create a pocket in one move, but I hear there's more potential for damage if done that way. I didn't need any stitches, an ordinary…
  • The campaign just ended with 80 magnets backed. Now the rest of the processing steps need to occur, which should take about 9 weeks. I'll come back with some pics and updates when they're finished.
  • The Titan campaign will end in 24hrs. There are currently 72 magnets backed.
  • The Firefly and the xGLO were commercially available glass tag implants that were lit by tritium. The Firefly was sold by Cyberise and came first. It wasn't "recalled" really, Amal just posted a warning on the forum because he'd had some r…
  • 42 backers to the campaign so far with 10 days remaining. The machining has already started to get ahead of things.
  • I'm currently exploring a company called Purewrist. They're a reloadable prepaid card, so the terms are not very favorable, but it's better than nothing. The chip/antenna combo inside the wristband is small enough to encapsulate and implant.
  • He hasn't told me the specifics. What would you do if you had funding for the testing worked in to the campaign? I'm thinking extended periods in an ultrasonic bath, and corrosion testing with a few different liquids (acid, hydrocarbon). If it won't…
  • He didn't seem to think there would be enough demand for a $500 magnet, but lo and behold we're currently at $15.5k when the goal was only $12k and there's 28 days left. Laser-welded titanium seems like a safe bet, but we'll see if they pass the …
  • I currently have a 3mm x 6mm cylinder magnet implanted in my ring finger. It wasn't too bad to get in, and I don't have huge fingers. I did the old switcheroo with my old magnet and some scar tissue came with. Helped make space. Cassox would def…
  • Hmmm. I might just not be involved in that side of it, but I haven't seen many books about the topic. Biohacking has really come into it's own in the information age, so most people share info over solely internet channels. There's plenty of books o…
  • @Muiren it depends on the frequency and the antenna shape/coupling. Commonly RFID uses 125kHz and 13.56MHz. In most cases the flesh doesn't attenuate the signal significantly, it's really the characteristics of the LC tank circuit in the implant tha…
  • Wow, thanks for sharing. I know some people who are working with e-textiles who I'm sure will be interested in your work. > @Muiren said: > A word about how I "science". I rarely offer opinions before at least some cursory resear…
  • Hmmm. That's very interesting. You might even be able to use a piezo element to harvest energy from ultrasound (although they respond better to lower frequencies). Once you've figured out how to harvest the energy, formatting it to run LEDs safel…
  • There was a bit of a divergence on whether to go battery or field powered. Also, none of the team members had the bandwidth available to lead the charge. If you don't mind sharing, what power source did you decide to use for your implant design?
  • Unfortunately, I don't think it would fit in a helix. The implant is 3mm wide by 14mm long
  • You could use an SLA resin printer or even a cheap DLP. You cure a small resin disc to form the bottom of the coating, stop the print, embed the magnet in that cured bottom piece (possibly need a biosafe adhesive) continue the print and finish the c…
  • I ended up using pros-aide to glue the magnet to the interior of my tragus. It worked about twice as well as the xG3 I have implanted (fidelity and range) but it still wasn't even 10% as good as dropping the magnet into my ear canal. I also have con…
  • The Schott VivoTag glass that the DT implants are encapsulated in is not likely to cause an immune response in anyone on its own. If you don't maintain a sterile field during implantation, foreign contaminants could cause an infection, but that's a …
  • If the glass that the implant is encapsulated in is biocompatible and bioinert, then you shouldn't have an immune response. Some chips you can purchase from sketchy manufacturers (primarily in Asia) can have lead or other contaminants in the glass. …
  • This is a well documented issue with the xG3. It is more of a "lifting" magnet than a "sensing" one. Because the amount of n52 magnet material is so large, it has a relatively large/strong field for an implant magnet. It also has…
  • Totally reasonable, it's valuable to maintain control over the variables while testing out new techniques.
