  • I take that bit about the glucose biofuel cells back. With the most efficient I could find you're only getting 43uW/cm². That's 0.26mA at 3.3V if you have 20cm² of area, and it has to be in contact with blood (not encapsulated in fibrin sheathing). I mean go for it, try out the peltier modules and see how much power you…
  • You're definitely limited in how much vasculature you can interrupt with these plates, and how much (if any) transdermal space you can maintain on the body to allow heat sinking. Seems like a huge sacrifice for a few mA of power, especially when the average Bluetooth radio is using 10mA+ and sensors consume a non…
  • Well, availability entirely depends on your region. I'm in the US so I usually would use eBay, Digikey, Mouser, or Alibaba. I've attached a picture of what they look like. You can use search terms like "Peltier thermo electric generator module TEG" and you'll definitely find some. Their output voltage varies considerably…
  • Hey, glad you found the forum! You should buy a peltier thermoelectric generator for a few pounds online and try it out so you have a better understanding of it's performance. Pretty much anywhere inside the body you will not have a sufficient temperature gradient to create any appreciable amount of power. You will need to…
  • Very interesting. I'd just caution that there are many different formulations of epoxy and you need to verify that you're using a biosafe one that won't slough off or release toxic byproducts when subjected to the hostile environment of the body.
  • Can you think of any strategies to get the magnet implanted closer to the eardrum without damaging your hearing? I've been trying to make tragus magnets viable for a few years now and the range just sucks. It never even remotely compares to dropping a small magnet directly into your ear canal, even with a 100W amplifier.
  • Fack. I'm not gonna make it. The cost is too damn high.
  • Hey so I know it's been a minute but the Qi receiver in an implantable form factor is coming along nicely. I'm just working out some kinks with the current limit while some other clever individuals work out the code that will run on the VoCore chip. Currently it's Gossa which is a fileserver. Once the Qi charger is more…
  • Sorry that you didn't feel welcome on the Dangerous Things server. I don't think anyone was trying to scare you off. Feel free to reach out if you want any help with the electricals.
  • The design worked well, but it was difficult for Amal to encapsulate because the z-height of the tuning capacitors was too great. My next step is to revise the design so that the tuning capacitor is two plates in the copper of the PCB. That's likely going to require two revisions to get right and ordering flex PCBs is…
  • There's a Dangerous Things forum that is very active, a Slack for this forum, and several subreddits and Discord servers
  • We have this ongoing community project called the Endochron. The original idea was betavoltaics from Widetronix, which we worked out with their CEO Chris. Unfortunately the NRC is making that difficult because it's too much tritium and the fees are upwards of $8000/yr for licensing (plus we may not be able to ship it once…
  • Some of us are active, we just have other communities where we post most of our developments. This is like the archive/neutral ground
  • They can be ordered if you contact [email protected] They're kind of unresponsive, but they'll get to you. It's the best option at least until the Augmentation Limitless storefront is set up.
  • Thanks. I'll be there
  • Hey @Cassox I sent you an email but never heard back. Have the dates for grindfest changed? Ahh, I see on the auglim site it is now June 10th-12th. I'll get some plane tickets.
  • Nebula Genomics is pretty good if you want the privacy.
  • I forgot there's also several subreddits: r/grinders r/DangerousThings r/DIYBio and so on... I wouldn't bother with r/biohackers. It's full of supplement red light therapy cold shower whackadoos
  • There's the Dangerous Things forum I linked you to, and an unofficial Discord channel. There's also the slack associated with this forum, although I've heard it's largely inactive at the moment. We seem to be in a lull where the last generation of grinders have either left the scene for life stuff, or have started…
  • Hey SkeinError, welcome to the party! I can definitely help out with some of your questions. Full disclosure I work with VivoKey, who are indirectly involved with Dangerous Things. * If you go to a professional piercer in the US, you can expect a fingertip magnet install to run anywhwere from $60-$150 depending on the…
  • I can help with that if you want. I design NFC antennas and convert payment wearables into implants.
  • Depending on the proximity of the locations, that should definitely be doable. You should make sure you eat and drink enough before the procedure, and warn the body mod artist if you're the feinting type. It's also going to be a bit difficult to drive yourself home, especially if they're in both hands.
  • It would be great to meet you in person, Sandra. I hope you can arrange to get out there. I plan to attend if it's happening. Too many years of missed opportunities to pass it up.
  • Make the situation fully known to the public by getting medical imaging done. That should be irrefutable proof. If a doctor says you have a neuralink implanted then you'll have support in your mission to get it removed and the perpetrators brought to justice.
  • Please do not attempt to cut anything out of yourself until you have actual proof that there is something to cut out. If you hadn't seen the Google image search and the heaps of misinformation about this online would you still think this is the cause of your symptoms?
  • Unless you have evidence to back up your claims I don't think we'll be able to help you. You may want to seek medical assistance. At the very least they can do imaging to determine if there are any foreign bodies implanted. Something like a neuralink would be very noticeable on an x-ray. With our current technology level…
  • My understanding is that they stopped making them because the transdermals weren't able to hold the weight of the device for extended periods without the skin getting very irritated and eventually rejecting.
  • Sent it off to Amal for encapsulation in his biopolymer. It will be nice to have my real debit card with a longer expiration date and no fees after all these Purewrist shenanigans. I wish there weren't so many players standing in the way of implantable payment...
  • Unfortunately I don't have one to trade, but I'm curious how long/often you plan to wear it for?
