For those unaware of magnetic implantation, there's a reason behind it. Basically the whole idea is that you insert a magnet underneath your skin at your fingertip and after the site completely reheals, electromagnetic waves will vibrate the magnet when in close proximity to a powerful enough source. This phenomena is collectively called "magnetic vision" and basically lets you feel magnetic forces around you - to a degree.
I became obsessed with this idea of gaining a new sense with virtually no downside and set out to acquire this myself. Having little resources for this sort of thing around me though, it was up to me to do my own total research, procedure, aftercare, and learn to use it properly. Because of this, I feel that if I can do it so can you. I'll share what I learned along the way to help you out.
First off, selecting the right magnet is paramount. A bare heavy metal magnetic is toxic to your body first off, and you should be aware that potential side effects go as far as tissue necrosis - your shit rots off. The right coating is very important. Currently, the best and most recent/advanced magnets use titanium nitride such as the M31. Also, gauss rating is a big factor. The more sensitive the magnetic, the better your sense so we're only interested in neodymium here. Finally shape - disk is the most sensitive practical sensing shape.
There are other coating out there I personally opted out of. Parylene-C is widely used but this is known to be brittle and prone to cracking. Cracked coating expose the magnet. Exposed magnets can potentially rot your finger off. No. Silicone is less brittle obviously but still not so tear resistant and presents other problems. IMO the M31 is the ONLY magnet worth a shit as far as a finger sensing magnet is concerned.
So you get your magnet and now you need to shove it under your skin. There is no easy way to do this, but first let's discuss ensuring it doesn't reject. Rejection occurs when an infection happens at the implant site causing the magnet to push back out of the site. Causes of this can be an unclean implantation site, unclean magnet, unclean tools, exposed magnet, or even a subpar immune system at the time of operation. For me the latter was a big concern because my primary painkiller was old school - brandy.
There is easy insurance against rejection. OTC antibiotics. It's known in many circles that fish antibiotics are perfectly usable by humans and do not require a prescription. In fact, I wager it's from the exact same sources as prescription antibiotics with the difference being that the FDA "inspects" the human goods while the fish antibiotics are more loosely regulated. This is a useful loophole for many other things and I suggest you capitalize on it. However, be smart about it. Know any allergies you may have and if in doubt, don't use it. Also, don't use it unless in dire need. Most commonly, the "biohacker" community uses "Fish Cin", OTC clindamycin. Accumulated experience including my one shows that downing 900mg of this directly before the procedure will help fight rejection significantly.
Second is proper sterilization. The M31 cannot be autoclaved but can be chemically sterilized. It comes with an ampule typically just for this purpose but there are many suitable agents for this. For your scalpel, gamma sterilized blades are a dime a dozen as are suture kits. These can be found cheap online easily enough. Look for kits that include the sterilized blades and suture kits in foil packs along with a scalpel handle. A pair of suture pliers may also come in handy.
Third, and why I mention suture kits - stitching the wound site after insertion. I made a mistake the first time by using superglue which was reputed to work. It's not as effective as pulling the skin together with a suture and I suffered a rejection as a result. I also did not use fish cin in an otherwise clean environment - for some reason it just wasn't enough.
The procedure is just a big shit sandwich. You're going to need to prep an area first off. Cover it in fresh plastic wrap after wiping the surface clean with alcohol. Then clean the plastic surface off with more alcohol. Set everything in an easy to access location but do not touch anything sterilized with your bare hands. You may also wish to have a bowl of ice ready for your implant hand. At this point, sterilize your hands with something like duraprep. Put on latex free surgery gloves - probably in any decent kit you'll find - and prepare the magnet. Place it into a sterile glass holder and soak in solution. Have a non-metallic rod ready - this will be used as a ramming tool if you know you've created a proper pocket but the magnet just doesn't want to go down into it. This is going to be a mess, folks.
Now it's time to stuff your hand into the ice for half an hour. Get tanked if you need to, I drank quite a bit. You're about to stab yourself deep and it's not going to be fun.
After waiting, it's show time. Remove the finger of the latex glove where you intend to implant the magnet. Mine was on the inside of my left pinky. Many advocate the ring finger. Pick a spot you know isn't going to suffer much mechanical stress but it must be at the finger tips - it's where the most dense of nerve clusters are and where you will feel the most. This unfortunately extends to surgery where it will hurt like a bitch.
This task done, it's time for incision. duraprep one last time and prepare your scalpel. Place the blade onto the handle - I recommend a number 11 as you can practically pierce straight down - and locate your incision location. Stop thinking and jam the blade in. Remember, you're trying to get the magnet under your skin but not into the flesh. You need to cut down at an angle to where you'll create a pocket under the skin where you'll insert the magnet but not so deep as to place it into muscle. You MUST be in this area, too shallow and it will push out. Don't sissy out and think you've got it when you don't. You need a deep pocket. You're going to bleed a lot and it's going to be hard as hell to see. I recommend sterile cotton gauze to periodically clean the site just so you can see.
When you think you have a pocket suitable, set the scalpel aside and retrieve the magnet. Having fun yet? Without delay, press it into the pocket as deep as you can. It must disappear from view, if the top edge is still visible, your pocket is too shallow. If it's not as deep as you think it should be, use the rod mentioned above to press it down further.
After success, press the area closed and prepare for a suture. You want to create as shallow a stitch as possible. Remember here (and for the incision as well) that your skin is probably tougher than you give it credit for. This will take effort. Make sure the stitch is above the magnet but also that your needle doesn't ram into the magnet. Run your line through and tie it so the skin closes. Bleeding should stop as soon as you do.
The procedure is done at this point. Immediately bandaid the location for protection against bumps and to pick up any minor blood. Have a topical antibiotic like neosporin ready and use this to regularly dress the site. After 10 days or so, it should be safe to remove the suture.
If you notice the site becoming a dark blue color and painful, chances are it somehow got infected anyway. This can happen but it shouldn't and the above tricks should prevent this. If it does, you'll need to remove it. It's recommended to wait 6 months before trying another implant upon the same site, or you can try elsewhere. The M31 will hold up but you'll need to resterilize.
If it doesn't reject - SUCCESS! Try not to play with the magnet too much during healing. It might be tempting to confuse people by picking up paper clips but hold back. After a month you should begin to feel strong enough fields. Try holding phones, hard drives, power cords to electronics, sticking your fingers near active breakers, other magnets, or security scanners.
Speaking of scanners, experience has shown that metal detectors do not pick up on the biomagnet.
