Group buy! N52 Au & Parylene-C Coated Magnets (again!!)
So there seems to be more interest in the magnets that @extrion76 got like 2 years ago. I just put in a quote request to K&J Magnetics (where they got them last time) So I should hear back soon. The magnets are NdFeB N52 magnets with a Ni-Cu-Ni-Au-Parylene C coating that are 1/16" (1.57mm) diameter x 1/8" (3.18mm).
More info from the original discussion: http://discuss.biohack.me/discussion/238/group-buy-n52-nd-au-parylene-c-coated-magnets-/p1
Who's interested?
Also, to anyone who got them last time, are you happy with them? Would you have gotten a smaller/bigger size/shape/anything else?

(EDIT: are these Cylindrical magnets? is that going to affect implantation in any way?)
That said, in my case (since I asked for 100, and you referenced that number) my reasons are threefold.
1) I like to keep a small stock on hand for my own testing. I've been buying magnets from a variety of sources just to keep them on hand for comparison. Granted I don't work in a lab, I'm just recording anecdotes.
2) A few of them will be "demos." super-glued or taped to peoples fingers so they can "try before they buy." Of course, I warn them that these particular magnets aren't exactly implant-ready. I don't know anyone that actually has implanted a magnet I've given them, but I know I've planted a few mind seeds
3) I have a few contacts that are interested in seeing what magnets people are interested implanting, I'm just finding them deals. Again, I don't expect them to actually do it, just see the product.
I like to keep a stock on hand for those reasons, and when a deal comes up may as well take advantage of it. Who knows, I may get bored and implant one myself. Probably not.
I also just really like magnets.
I know there is nothing "medical grade" about K&J, and I feel SMM magnets have the same concerns. That pretty much leaves VP scientific, where the magnets are N48 at best, and Steve Haworth, who is really expensive.
Has anyone reached out to labs and engineering firms for their own custom Parylene or PTFE coatings on magnets? Why not specify parylene thicker than 20 micrometers, or see what other firms can offer? (Should I open a new thread for this?)
