  • The Stentrode by Synchron seems like a much more reliable method of getting BCI to market.
  • Oh... I'm not sure I'm following. Medical companies do it for their own internal benefit. RFID biohackers do it because they have to use commercially available chips with IDs, we have no choice. For any implants you make that don't use NFC you can omit any form of unique identifier if you want. I can see where it would…
  • The identifier is probably to distinguish the units during assembly and distribution. The only real use-case I can see once it's implanted is to identify which batch it was from if it failed prematurely
  • How many euros is a whole batch and how many units is that?
  • What? You wouldn't be able to use that at a payment terminal.
  • Nope, sorry. There are reasons I only shared them with Cassox. You might be able to find them online though. If you want screenshots of specific passages I can DM you.

  • @Cassox I have all the docs for ISO 10993 Biological Evaluation of Medical Devices. I'll email you.

  • Plus, at some point you need to transition through the skin, either at the edges of the peltier plate or just with wire contacts. Creating reliable transdermals is no small feat
  • 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.
