  • I would say it really depends on in what context you want to do 'biohacking'. If you're interested in making money from it you really don't need a degree, your time is likely best spent elsewhere (online courses for digital electronics, programming, basic biology, and of course just experimenting with things and having…
  • Good to meet you! I'm currently an undergrad in electrical engineering, been in my current lab for a year now, and plan on pursuing a PhD. I wouldn't say the applications of biohacking are limitless to healthcare; I would say the advances made in healthcare open limitless possibilities for biohacking. Biohackers are…
  • So how many hands have needed amputation?
  • Based on what we saw at Grindfest watching @Cassox run those tests, I think the chemical Nickel assay needs to be redesigned to be more rigorous and quantitative. Seeing as how this will be going inside people (and other TiN-coated implants probably will in the future), I think it should be a priority to develop a…
  • @AlexSmith how are you going to be testing the coating integrity?
  • We would need to set up an IRB and make sure to get written informed consent if the site is in the United States so that all research done would be legally sanctioned.
  • Lol I'd take less false and less interesting over the alternative any day of the week. Look forward to your update.
  • Crystals yes, nanowires no. Nanowires you would not be able to visualize using an optical microscope. Hence the "nano".
  • @JohnDoe again, I don't know that you can actually take the parts out without destroying them. Even if you could you wouldn't want to. You can buy smaller, similar parts more specific to your application (which is...?) for much cheaper that will be much less of a pain to deal with, such as an AVR microcontroller. EDIT: Why…
  • @JohnDoe you're absolutely correct, smaller is better if you want to stick it inside yourself, but that's not smaller. That's gigantic. And more expensive. And more difficult to program and modify. I'm not even sure you can remove most of those chips without destroying them. @TheGreyKnight I totally understand the desire…
  • Ok, perhaps I should have made my questions more specific. Why does your goal mentioned in (1) need to be implantable? What will you gain by having it be implantable? Yes, I understand the urge to want to shove technology under your skin but what's the justification for it here? If your intention is speech recognition and…
  • Ah, sweet, sweet criticism. I have missed seeing it on this forum. @garethnelsonuk a few questions for you to answer: 1. What purpose will it serve? Not a theoretical purpose you think it might serve in the future but what right now would this project be able to provide? 2. Why can't this be put in a smaller form factor? I…
  • @glims are we reading the same article? All I saw was the authors repeatedly stating the differences in hippocampal volume between placebo-treated and drug-treated patients was not significant. I'm all for drugs to promote neurogenesis, but at least use one that has evidence of its efficacy.
  • If you're the target of a specific attack your information is going to be obtained, and there is nothing you can do to prevent that, you can only make it more difficult for the attacker. So that's a moot point as well. They want your bank account info and you have it stored on an encrypted device? Or better, in your brain?…
  • ^ see above response.
  • Er, no it's not. It only fails when the obscure becomes ubiquitous. Which, in the case of implantable RFID technology in the United States/UK, barring some massive cultural shift is probably not going to happen within our lifetimes. And in the case of RFID tags, the fact you need to be either touching or very close to…
  • Ok, I very much appreciate both your dogged determination and your use of academic sources, but NO THAT IS NOT WHAT THAT PAPER SAYS. "Weakly mutagenic in mammalian test systems" means that this material can act as a mutagen (increased risk of cancer, an actual health risk). The cytotoxicity results in that paper also say…
  • Sorry to hear that, Universities IRBs tend to do that. Why on earth are you developing a subdermal electromagnet mount? You want to implant an electromagnet?
  • Also, titanium nitride (TiN) has already been tested and actually used for some rather extensive bone implants: http://www.azom.com/article.aspx?ArticleID=2568
  • Very well-done video. Very appropriate soundtrack.
  • No. This system can only scale down. Let's think about what is driving it for a second. The hydrolysis of ATP. Well, that sounds awesome, the body uses ATP, that makes this the perfect candidate for a whole array of implantable devices. Unfortunately it's not that simple. Yes, the body uses ATP, but (almost) all of that…
  • As a fellow string player (cello here) I would recommend implanting in a finger of your right hand.
  • If you're going to mention a vague-sounding technology with even more vague and broad applications please provide specifics or don't make the claim. If you have to wait to talk about it, then wait. As I'm sure you know, disease treatment is not and cannot be based around a single technology. You found a way to perfectly…
  • Defeats the purpose of being transdermal, since piercings heal around whatever you inject. It's just the same as if you were to set the tube on top of someone's skin.
  • No, that's not exactly how it works. The way EEG activity is typically made meaningful (and really all non-spike neural data) is by sorting the data into frequency bins and plotting the intensity at those bins over time. This is called a spectrogram. If you are only recording at 20Hz, you can only capture 10Hz signals in a…
  • "Better than a centimeter" does not mean "a few millimeters". The authors also say the relatively low SNR "in reality requires that data is averaged across subjects". I.e. cannot be used reliably in real-time (required by a BCI), but can be useful when studying brain activity across multiple people. While it has better…
  • Unfortunately the authors seem to be silent on device design, so I'm not sure what they mean by "low cost" and "compact". Also, they stimulate the exposed nervous tissue directly. it isn't realistic to think you would be able to achieve anywhere near this resolution after dealing with the absorption and scattering of IR by…
  • Claim => Seems to be legitSupporting Evidence => Should be found by person making claimSubject Interesting Otherwise => No
  • Not a bad question, as I assume you have no cell lab experience you have no way of knowing the size requirements of a lab.
  • Magnetic fields are responsible for the nerve stimulation, and magnetic fields are induced by a moving charge (current).
