Try it before you buy it
been pondering the idea of an NFC implant for a few weeks. To help me decide I
ordered an NFC ring and I’ve been using it to unlock programs in my phone for a
week now. Nothing secure, just things like SMS and Facebook. But if someone
found my phone I wouldn’t want them to look through all my personal stuff. This
isn’t high security but someone who finds my phone lying around hopefully won’t
to go through much trouble to read my texts and look at the cat pictures I
exchange with my roommate. That’s not a sexting joke, we like felines.
After a week of wearing this goofy ring, it’s pretty
hideous, I’ve decided that I would benefit from an implant enough to justify
the commitment, cost, and risk. The three biggest complaints I have about the
ring is that it is uncomfortable, it is unattractive and it doesn’t always read
properly. The first two problems are issues with the ring itself. I actually
have cuts where the sharp edges have dug into my hand. These problems would not
present themselves with an implant.

After reading Amal's posts and seeing his videos I feel confident buying
his NFC kit and rest assured, I will have a professional put it in. You may
remember how grateful I am to my piercing artist who put my magnet in. And
stitched me up. Both places.
What other ways can people experience enhancements before
they get implants? Taping a magnet to your finger isn’t effective. I’ve combined
magnets and earplugs so that EM fields can be heard and that method can pick up
smaller signals than my finger magnet. I would like this to focus on passive components. Things like Northpaw are beyond the scope of what I'm going for here. This is intended for me to write a primer article
so that people can “test drive grinding” and maybe alleviate some fears.

I’m horrible with titles and would appreciate
suggestions. This article is not being written for any specific publication,
just to have a nice neat piece curious people can print, share, and try at home.

To give a bit of background on how I do it, i usually use a neodymium disk, generally about 2mm thick and 8mm in diameter or so, and then just stick that to the middle of a piece of tape, (normal scotch tape works well, but anything light will work,) and I then have the person stick it to their finger such that the magnet rests on the pad of the finger, and so that it is just barely in contact with the finger, with no pressure. If it is not in contact with the finger, or if there is pressure, it won't work. But once it is positioned right, I'll usually use the power brick to a set of desktop speakers and they can feel that almost as well as if they had implants (using my own experience with it and comparing it to my magnets.)
Let me know what changes you would like to see. I want something you can hand to someone and they can get an idea of what makes grinders tick and something they can read in a minute or two.
I don't think I found a big enough wall transformer but something like a laptop power supply might sound interesting. You'll probably the same thing with each, a 60Hz sine wave.
Mine is also very effective to read on my phone (Galaxy s7) but have noticed it being worse on others I've tested on.
I will say the coating on it does eventually fail like mine so one of the rages is partially exposed now.
As far as taping a magnet to my finger, I could never really get a good sense from doing that. What did work was gluing one on my finger using rubber cement or even white glue. Obviously the glued on magnet doesn't stay on very long but I could sense some wall wort type power supplies like the one powering the computer router. The only electric cord I could sense at all was a large cable powering an air conditioner.
No special high powered, implant safe magnet was needed either. I broke some chips off a big refrigerator magnet and glued a tiny chip onto my finger and it worked too. Waving my hand over other magnets was a fun experiment but sometimes pulled the little magnet off my finger or pulled it out of the glue. Surprisingly, the tiny slivers of magnet often worked better than the larger one.
