Really interested, but I'm not sure I can get someone to implant it... Not quite as easy as an RFID.
-
Does the Ti interact with the magnetic field in any negative way? If it works, I'd be down to get one.
-
@tasty No trying to put down your idea (it's fantastic on paper), but having contacts wont do much good for something this big/radical. Realistically, for this idea to work, you need a pretty high % of implantees. If the % is too low, checking for a chip will, on average, only waste precious time and therefore render the…

Good luck with convincing people to get implants. Sadly biohacking is still extremely marginal, the vast majority of people would instantly reject the idea of an implant. But other than that, yeah it would work easily.
-
@Helyx Arent the wires sticking out the electrodes?
-
@ThermalWinterTo be honest, 18$ feels like nothing for a well coated magnet. I'm totally fine with that. Wouldnt TiN be the best option? Technically it wouldnt require a second layer, right?
-
@dieselpwr It goes without saying, but try to keep the plastic at the lowest possible temperature. If you get close to the curie temperature (above ~310C), the magnets wont be remagnetizable again because the internal structure changes.
-
@ThomasEgi Yeah, 10cm is definitively too big. It would be pretty realistic to go for a 1cm diameter coil. Probably even 5mm. That should massively reduce the current required. @dieselpwr The key point is to get the fastest discharge possible (since the peak current is the only thing that matters, even if it lasts for…
-
@ThomasEgi I'll have to recheck my hardware, but that seems like WAYYYY too much to me. We magnetize SmCo magnets at full power with around 300 amps. Making smaller coils would certainly help too, why did you pick 10cm?
-
@ThermalWinter Pardon my ignorance, but why is titanium not available? I know it cant be used as plating material, but could other techniques be used? What about titanium nitride?
-
Remagnetizing neodymium isnt trivial, but it's certainly doable. I work on a project where we do just that. Basically you want some huge capacitors and heavy duty thyristors. Charge them up as high as you can go and dump the whole thing through a coil.
-
Oh boy that doesnt look like a whole lot of fun to implant! Still looking forward to it though.
-
Yeah, I think I'd prefer no anti-migration coating too... To me the idea of being able to remove it easily is more valuable than having it placed in a very specific position (To me at least).
-
Definitively getting one, they look awesome in the dark! Chicken skin picture would be nice too. I'm mostly curious to see if it could really be used as an implanted flashlight.
-
Definitively want one of these, they look great! Can we get a picture in the dark?
-
Induction stoves dont use magnets (as far as I'm aware), just just pass AC current through a coil, which creates a magnetic field which in return induces currents in the metal. You would most definitively feel the magnetic field with a magnet, not sure if it would heat up though.
-
Want! Want! I work in a research lab so maybe that would be enough to make a purchase, how do we work out if it's possible?
-
That sounds really great, I'm interested.
-
Not sure if I could really contribute much, but the change would bring it after my finals so I could technically attend.
-
No problem, I'm glad to help.
-
I honestly have no clue, if you send me a link to something of theirs I can check.

Wooo the TENS unit + control is now working and twitching the shit out of my arm!https://www.youtube.com/watch?v=IyLo9F75gBw Control is fully analog (course requirements) and features a low cutoff to allow for slight variations from normal posture + a upper clamp to max out the output at a predetermined level. Now that I'm…

Here's the paper: https://drive.google.com/file/d/0Bwz0nt-tZhu4VWllczcyMnNCWms/view?usp=sharing If anyone needs papers from behind paywalls, hit me up, I can access a lot of stuff via my university.

ok Edit: fair enough
-
I dont have the schematic at the moment since its a modified version of the Silicon Chip TENS unit: http://imgur.com/gallery/0tSu2 Basically, I dropped the intermittant output and changed the IR2155 for a IR2110 and a 7555 timer since the IR2155 is no longer in production. Other than that, it's mostly the same with a few…
-
Didn't have much time in the past few weeks/months, but I'm happy to say the project is advancing. I've built this TENS board, runs up to around 80V with frequency and pulse width adjustments. I've been trying to figure out what the best settings would be to induce the buzz sensation, but it seems that my skin is very…
-
Check out KiCad, it's open source and pretty easy to use overall. Lots of tutorials available.
-
So I've been looking into things and I'm having trouble finding data on the frequency, current and voltage I should use.What I can find is either less than noticeable or too strong. Does anyone have an idea of the range of values I should be using?
-
It closes up by itself after a few days. If you can, take a few days off. If you can't wear a good pair of gloves.
