  • Please add me to the list. Thanks!
  • Cassidy730Cassidy730 July 2016
    Me too please! :)
  • JohnDoeJohnDoe July 2016
    Do you have plans for offering the M36 soon?
  • AlexSmithAlexSmith July 2016
    Added to the list. 

    While I plan to eventually offer M36s, they will still be awhile after the m31s
  • BenbeezyBenbeezy July 2016
    any updates from @AlexSmith ?
  • AlexSmithAlexSmith July 2016
    Yes. The second lot of magnets has finished manufacturing and has arrived at my friend's place. Now I need to get them shipped to me for testing.
    Also, the first lot was finally released and returned to the manufacturer, so I had them sent to my friend too.
  • AvioAvio July 2016
    @AlexSmith I sent a message about being added to this list, but I'm not sure how often the messaging system is used here, so I just wanted to post here saying that I'd like to be added to this list.
  • ZerbulaZerbula July 2016
    Yay :D
  • ToasterToaster July 2016
    im really looking forward to these. hope testing goes well.
  • ChrisBotChrisBot July 2016
    @AlexSmith, will update status tonight

    Edit: Updated.
  • @AlexSmith Could you please add me to the list? Potentially for the next batch if you begin running out of room for others. I will only want one. Thank you!
  • TortelliniTortellini July 2016
    I've been trying to get my hands on a magnet since I first heard of them last August..... I would also like to be notified when they become available. Thanks.
  • AlexSmithAlexSmith July 2016
    Added. if all things go well with the current shipping I'll have them in a few days. Then I'll do testing :D

    Now seems like an appropriate time to talk about testing. Aside from the optical and chemical tests, what are people's thought's on in-vivo tests?
    Assuming the chemical tests show no problems, I intend to implant one myself and remove it again about a month or so to check for any signs of coating failure. How long do people thing I should leave it in for? do other people also want to do in-vivo tests?
  • ZerbulaZerbula July 2016
    I have an idea for a test... I'm not a hundred percent sure it would work... Maybe you could manipulate things to make it better...

    I think it should be able to withstand a hundred degrees Celsius... Right? Is there any reason it would be a bad idea to boil a magnet in a super saline solution for a period of time? I would be interested to see if the temperature, corrosiveness, and possibly mechanical movements from magnets being boiled together would cause the weak ones to fail.

    This is speculation, I'll be interested to see how this hold up before doing the gravimetric testing, then again I'm not completely sure what I'm suggesting just out of familiarity. ^^'

    I'd volunteer to be a proxy for In vivo, but my life is in chaos right now. ^^ if you still doing testing by the time I'm more stable, I want to volunteer. ^^
  • ChilliEyeChilliEye July 2016
    I'd test for you in vivo.
  • AlexSmithAlexSmith July 2016
    @ Zerbula sadly rear earth magnets are very sensitive to temperature, even 100c will damage them :(
  • ZerbulaZerbula July 2016
    Thought so... Would be possible to change the pressure to lower the temperature? Like, in a pressure cooker maybe :o
  • AlexSmithAlexSmith July 2016
    Maybe, but pressure cookers are built to increase pressure, which would also increase the temperature needed boil water. It might be possible to modify it to decrease pressure.

    Saline soaking can be done at room temperature, and magnetic stirring machines are thing. That would only leave out the temperature competent of the test you proposed, but I think that's unavoidable since the magnets would be damaged by any high temperatures 
  • Is the test to show the survivability of the coating or the magnet? If its for a coating frankly who cares about damage to the magnet strength.
  • Also im not really suggesting doing it to all of them either but more of a test on a single or what have you.
  • AlexSmithAlexSmith July 2016
    For random sampling of coating quality, you are right, it doesn't matter if the test demagnetizes the magnet, but it can't be used for magnets we actually want to implant.
  • ZerbulaZerbula July 2016
    I'm used to seeing things traditionally getting more reactive/interesting when they are warmer than cooler, such as washing dishes or cleaning parts for chainsaws, as proxy.

    Not necessarily 'high' temperatures, but simply high enough to cause reactions. Our bodies are definitely warmer than room temperature... At least core. It would make sense to me to at least exceed core tempuratures during testing would be my two cents.

    Also, native habit of debris, cleaning, and in this case integrity and damage testing with my personal experience has seen heat cause more thing to happen. ^^

  • AlexSmithAlexSmith July 2016
    yeah "boiling" at 40c should be fine, it won't actually boil, but we can simulate it with warm water and a stirrer. And for a actually boil a few sample magnets.
  • ZerbulaZerbula July 2016
    Just trying to think of ways to stress it. ^^ 40c sounds ideal. :3

    Hmm... I'm trying to think about what causes these to fail... I'd honestly say maybe take a small random selection of batch and see what it takes to cause mechanical faults as well. It would be nice to get baselines of which magnet batches have what durability consistency on average. ^^ Like... What's the 'crush tolerance' on average for these batch of m31s, are they going to be less resistant to accidental impacts than the Ni-Cu-Ni undercoated TiN m31s? Just checking for consistency in strength too.

    And ideally having a replacement for the gravimetric testing, but I'm sure this is already being looked at.

    For the sake of fun, try to see if you can mess one up with a scalpel or a needle? I haven't heard of any being messed up during the implementation, but it would be interesting to know if it's accidentally possible...
  • AerisAeris July 2016
    Could you add me to the list as well? I'm pretty hyped up for this.
  • NymeriaNymeria July 2016
    I am new to this community and very interested to get a magnet implant so if it wouldn't be a bother could you put me on your list? @AlexSmith
  • AlexSmithAlexSmith July 2016
    Added. I too am excited. I am really really hoping this coating technique will finally solve the issues with previous magnets. As long as the chemical test results are ok I'll be implant myself asap.
  • vatratvatrat July 2016
    I'd like to be added to the list, too.
  • eggiteggit July 2016
    Well, I was trying to refrain from being annoying, but I guess everyone is doing it now. Can I be added to the list please?
  • AlexSmithAlexSmith July 2016
    added. If DHL is correct, I should have the magnets the day after tomorrow :D
  • DACPADACPA July 2016
    Good news, Alex! I hope that they get allowed through this time.

    On a related note: how are you intending to process the requests, in terms of payment? I cannot get your site to load but maybe that is just me. And how many magnets have been requested via this channel and elsewhere and how many are you receiving?

    Thanks for keeping us appraised!
  • DahPuffyDahPuffy July 2016
    I dunno if im a bit late, but please add me to the list too! :) @AlexSmith
  • AlexSmithAlexSmith July 2016
    The magnets are here! :D
    I looked at a few under the microscrope, some have obvious defects, some look ok as far as I can tell just from a visual inspection. Below is an example of each:


    chemical testing will happen this weekend.

    @DACPA  hmm not sure about the site, loads ok for me, maybe try again? I got a total of 200 magnets this time, not all will pass testing, so not sure how many will be left after, will keep people updated as testing continues.

    @DahPuffy  added

  • DACPADACPA July 2016
    Great news! Those are looking great. 

    I retried the site last night (for me) and it did reload. It had gone a couple days without. I'm sure you'll let us know what passes the test and what the next steps are when you are good and ready. Hopefully with a first batch through the system this will pave the way for whatever future demand there is.
  • AlexSmithAlexSmith July 2016
    I soaked a few of them over night, it's too early to know real results, but looking at them under the microscope this morning shows some failures and some apparent successes. Will keep them soaking them over the next couple of days but if the early results are correct it looks like I'll be implanting one next week
  • Those are some excellent pictures.  Exciting  times! : )
  • AlexSmithAlexSmith July 2016
    Been doing more testing, still a high failure rate, >50%, but low enough that this looks like it may be a feasible manufacturing method. Unless things go badly I'll implant a magnet on Monday.

    here are some more pics

    edge view of a magnet:

    max zoom microscope will do, can't get the whole magnet in a single image:

    here is a magnet which failed testing:

    this magnet had the same soaking as the one above but shows no signs of degradation:

  • Thats pretty awesome i was wondering what they looked like with failure vs not (yet).
  • JadeJade July 2016
    I would also like to be added to the list!
  • JoshJosh July 2016
    Super stoked by the results!  Would love to be added to list :)
  • AlexSmithAlexSmith July 2016

    Not a whole lot has happened since the last update. A few more failed, but I've still got a decent number that show no signs of failure after ~48 hours of soaking.

    I will definitely be implanting one or possibly two as soon as I can get a friend to give me a hand (uh... no pun intended, I'll be implanting in myself, just want someone to help hold things).

    I think I'll implant in my forearm, it's much easier and since I'll be taking it out in a few weeks there doesn't seem like a lot of point implanting in a fingertip. 
  • AvioAvio July 2016
    I'm pretty positive that I've asked this before, but what was the pricing going to look like?
  • ZerbulaZerbula July 2016
    Loving the progress. ^^ :D
  • mmuyskensmmuyskens July 2016
    What are the specs on these?

    I'm curious to know what type of coating?

    n52, i assume?
  • AlexSmithAlexSmith July 2016
    Just implanted one to test in vivo. Used a standard 2mm RFID needle to make a hole about 6mm long. First pic is from just after removing the needle:


    Then tried to force the magnet into the hole by hand, but it didn't want to go in:

    Then we used the plunger from the rfid injector to push it in, once it was inside the hole I used another magnet to pull it as deep as possible:

    There was a small amount of pain then sicking the needle in, but no pain at all when playing around trying to get the magnet in, now it's been about an hour and there is a slight dull ache, but nothing bad.

    Now we just have to wait and see how it heals.

    @Avio  I had estimates before, but I'm not sure now, what seems like a reasonable price?

    @mmuyskens  The magnets in the pics all only have a TiN coating, nothing else, the one I just implanted is also TiN coated, but has a nickel base layer. 
    Yes, strength  is n52.
  • mmuyskensmmuyskens July 2016
    Nice job. I'd suggest we keep the pricing around $50 for full install kits, and maybe a little less for those wanting magnet only. Not like there is much competition currently to slash prices lower. This will probably be the pricing I follow with the batch I'm getting.
  • eggiteggit July 2016
    I've got a microscope I use at work with a lot higher magnification, around 10x more I'd estimate. If you wanted some higher res/zoom photos I could take some for you. I can also take measurements, width and depth with around 2 micron accuracy. Might be useful to measure coating thickness on the failed ones. I suppose I could measure it on the good ones too by comparing to an un-coated magnet. If you are interested let me know.
  • AlexSmithAlexSmith July 2016
    The wound is healing nicely and I've stopped covering it. Slight pain if I bump/press on the location of the magnet, but otherwise I can't feel it. No magnetic sensations, but that is expected since there are far fewer nerves in the arm. Unless it starts to look unhappy I'll leave it in for 30 days, then remove it and check it under the microscope. so from here on out, no news is good news.

    mmuyskens  what would a full install kit include? the ones's I'm currently selling cost only slightly less than $50 to make, I'm not sure I can include a magnet and still come out ahead (partly because my prices include shipping).

    @eggit that would be really cool. I'm not sure there is anything to be learned from comparing failed vs not failed, because if the coating fails it starts at a single tiny hole in the coating and spreads outward, I don't think it's an issue with overall thickness. Still it would be very cool to see very high zoom pics. Lets wait until the current testing is done, if they hold up ok I'll send you one to take pics of.
  • mmuyskensmmuyskens July 2016
    By kits - I was thinking minimal. like chloraprep and a happy face bandaid.
  • AlexSmithAlexSmith July 2016
    Oh, yeah, that's more feasible, I was envisioning full on implant knits with medical tweezers, scalpels etc.

Howdy, Stranger!
