cool. what's the biggest mason jar you've pulled hard vacuum in @chironex?
-
What kind of vacuum are we talking? I've read that ball mason jars can withstand 25in/Hg before risk of implosion. The jars come in the gallon size for $35-40 in indiana. I recently opened a jar of peppers I canned and a lightbulb went off after I re-read this discussion. Edit, nope, not enough. That machine needs to be…

/\ which would be a requirement for coating magnets.
-
Ya, we're thinking alike. Let us know how it turns out. edit, based on @cassox recommended sizes yours may have trouble healing and may reject. Hopefully he can chime in.
-
Outstanding! @cassox, how would you compare abrasion a wedding band might face to that of, say, a finger mag in a pinky? @puzbiks1, where are you putting your mags? And what are they coated with that need be removed? If the Rh coating were to wear though, your blood will eat right through that copper and into the Neo.…

I saw this on my fb feed. its an adjustable z-axis pcb printer. So I thought pour the base, set, touch-off z-axis, print, set resistors and chips and the like, pour layer, set, touch-off, print, repeat... I'm not sure atm how one could make the conduit material elastic, and even more, without changing the resistance in the…

I like the idea of flexible pcb. Also taking inkjet a step sideways, is it possible to 3d print a blank layer, then print gold traces, then another blank layer, so on and so forth. you could even print short wave antennas and inductive charging circuits. As long as the layer is flexible, biosafe, and nonconductive. I think…

Ive never read about iron nitride. Ive have machined some crazy hard, high $$, high nickle content stainless steel. Designate PH 17-4. I bring it up because of all the materials in the shop this is by far the most attracted to magnets. Ive wondered how well it would do if it were permenantly magnetized. i dont have the…

what i know about rhodium is this, biosafe, platinum class, durable, common plating for white gold, can be plated at home. i wonder, since Rh has been known to wear off of jewelry as its worn how is this likely to translate into implant wear? It sounds like a winner if the durability factor is high. I'd like to try rhodium…

Heres an abstract about adding silver to the sol-gel HA fibers @chironex http://onlinelibrary.wiley.com/doi/10.1002/jbm.a.31197/abstract;jsessionid=4684BBDBC8F8EE272DD37BC5F7D4421C.f01t01?userIsAuthenticated=false&deniedAccessCustomisedMessage= I dont have my wiley account anymore to read the whole thing.

it sounds as though you want to build a smart arduino. Or rather an array? There is already a fairly small single board computer that runs on linux and has low power consumption. Has anyone worked with raspberry pi? The A+ model is smaller and a bit stripped down but its good. Also, orange pi makes slightly larger models…
-
in keeping with the initial post format; Class one;order gold plated magnets (inert base coat), electroplate with rhodium as @cassox mentioned in another gold mag thread. Im also finding papers that mention applying a thin coating of Ag to make the implant temporarily bioactive during the initial healing process then the…

I deffinatly agree about having holes in self education. I had 2.5 years at an engineering school before i had to take a break and make money full time again. That was 3 years ago this month. And while ive learned a boat load researching on my own, it wasnt until i wanted magnets that i realized im primarily into energy…

i was reading that article about the night vision and saw cassox in the picture and was like, hey that looks like cassox. have you done any follow up work on that? 50' is pretty impressive for being like a temporary videogame like attribute. have you written any other papers or articles about it?
-
I see your point about the plastics and yea the thickness of sprays or dips is a turn off. Im interested in the nanofiber making process. i read a little bit over the past couple days but mostly abstracts that dont go into depth on the process. One mentioned ammonium hydroxide. for magnets I think microwaves and ovens and…
-
I read up on a little of the HA work. It seems like the fibers can be made from a variety of feed stocks. I have machined a few material i recently learned were so medically important, PEEK, PE, and Teflon. While mine probably isnt medical grade it got me wondering if any of these materials can be vapor deposited reliably…

While am implant is likely in my future, id say the most important, rather, the most useful thing ive learned in college is proper R&D techniques including testing methods. once i learned that its as though the knowledge never stopped streaming in. ive learned more after formal schooling than i did while attending.

Sorry to double post but im having problems posting from my phone. Anyways, i will keep looking into coatings. Im a machinist by trade so im familiar with electrocoatings and anodyzing and such. I studied with a few biomed guys at Indiana Tech and gained a basic understanding of implants and and compatibility.Just enough…

bingo, found something. Its an electrospun nanofiber coating that takes well to Ti. http://electrospintech.com/coatedmetal.html#.VizulsvD_Dh

Ive been following the coatings discussions going on and while i was surfing the web (do people still say that?) I came across this article about a new nanofiber coating system that can also deliver antibiotics to reduce the chance of post-op complications that can trigger a rejection of the implant. It could go on over…
