So you know how some people stickerbomb their cases? And others might do the same thing but with little fridge magnets or company badges (personally, I have a magnetic metal ASUS logo on my case), anyway, the back side panel of a pc case has a lot of surface area. I also realized that it gets very hot. Would it be a dumb idea to get a massive, low profile heatsink with a fridge-magnet-type back, and stick that to the back side panel? My brain says its stupid but my heart says do it.

Summary A big amount of magnets that can trigger medical devices like peacemaker or other medical equipment used in the body, that could pose to be deadly hazard for some. That a heart company used to try and recreate what could trigger this in a study with such a phone. Found out by having it close or in the chest pocket (if you have that) could trigger the device. The iphone 12 seems to have enough mangets to trigger these devices in a certain distance. Quotes My thoughts This could be what makes a law about magnets in commonly used products, if it gets enough bad attention or find it as importent enough to make a rule about that on said devices, etc? Only if this get enough of the right attention. Like if with foods, you can have this much per ... but the same for magnets? like excluding stuff that is just mangets or based around magnets?

I am about to buy cablemod widebeam LED-stripes for my Define S. I was wondering if the case is magnetic, so I could get the magnetic version of the LEDs, or should I go with the foam adhesive version.

Hey, I've always been fascinated by how computers work. And I've wanted to build a 'computer' using rudimental technology ever since. I watched Linus's video with Destin and decided it was about time I built my own memory and logic. So I went and bought myself some Ferrite Toroid Magnets. I was wondering if y'all could help me out with all the specifics? How do I measure the threshold voltage required to flip the magnetization of the toroid? Should I trace it's Hysteresis Curve, if so how? Does the gauge of the copper wire matter? What waveform should I input? Does the frequency matter? All the help and insight is welcome!

It all started with my Sennhieser HD201, my first decent headphones I bought for myself 4-5 years ago. 4 DAYS AGO (July 6, 2018) F**cked up is the state I would describe it when I found it in the scrap electronic parts in our attic, after years of neglect on top of being broken in the first place. The whole fixing the headphones thing was a 2 day affair, involving cleaning, disassembling, stripping, designing broken parts in cad, printing said parts on my 3d printer, getting the dimensions wrong and adjust and reprint again, sourcing audio wires and jacks, and actually fixing and assembling it back together. The night that I finished it I went on like a fever dream frenzy of constant streams of ideas and concepts lasting from 2-4am, as you do. I've got 3 decent ideas from that trippy, almost hallucinogenic, stream of mechanical/modding/concepts ideas of varying practicality. The one I'm doing first is my idea of a removable cable for the headphones I just fixed. My daily driver headphones right now is a Sony MDR-10rnc it's removable cable is just so convenient to me, frequently leaving my work area to do something else I'd just removed the cable leave with my headphones come back and just plug it back. My first idea of it is just stick a male and female 3.5mm jacks around the part of the wire where it terminates to the two headphones and call it a day, I been always itching to do a magnetically connecting wire design for a while now, looking at my schematic notebooks as far as a year and a half ago... While my earlier attempts fell through, executing it here seems to be a more doable endeavor from the fewer connection points needed. My earlier attempt at this concept, (I made some prototypes of this but didn't work out as planned) TODAY (July 10, 2018) Here's a rough sketch of what I'm aiming to do: The main problem I encountered in my first attempt doing something like this is the connection of the wire to the magnet. Involved trying to solder the wire straight up to the magnet, long story short solder doesn't stick well to magnets and the heat conducted by the magnet in the soldering process took away a LOT of it's magnetism. My new Idea is to wrap the magnet with a thin metal sheet, something like an aluminum from a coca-cola can. and screw the wire and the metal sheet together to the housing. I solves my main concern coming it to this new idea by sidestepping the whole issue by not connecting the wire to the magnet at all. This also ensuring good mating because of the metal sheets being sandwiched between the two magnets. Here's what I've done so far in Fusion 360. I've done the housing, the wires and how the magnets will be mounted. Completely new to the sheet metal workspace within fusion I'm still feeling out how to do stuff there. I've done this all in the span of about 3 hours. could've done it a lot quickly but I was also half watching "The Smash Bros Documentary" by Samox on youtube along side the cadding work lol. I don't like much listening to music or podcasts while doing cad works and elected to watch a documentary or some other long form video when doing this sorta stuff. My productivity is practically halved, but hey the I'm enjoying myself way more than I should've had. That's all my progress so far. Tomorrow I plan to finalized the design and try to start to print it. Hopefully this project won't last me more than 3 days... Hopefully.

Hello everyone, This has to be the lamest mod ever, I've ordered x20 (used them all) tiny neodymium magnets (6x3mm) so I can attach my front dust filter to the case (front metal mesh) since I broke off all 4 of the plastic clips (right word?) result of the combination of fragile stuff and my clumsiness. So as the title says, will it be safe to put strong neodymium magnets directly over my x2 140mm Corsair fans? I would say they're a good 5-6cm away from the hard drives so I think I'm good there, but the fans concern me the most. Appreciate ya!

Greetings. I have a few fridge magnets I've collected during my travels, but rather than stick them on my fridge, I through I might put them on my computer case. Right now, they're on the right side-panel of my case and are pretty close to the hard drive, which is mounted at the top of the mesh on the front, right below the USB ports (image attached). Does this pose any danger to the hard drive or other components? (Neither is directly behind the motherboard, although the Niagara Falls magnet does get a bit close).

Hey guys I have an I-Ball Pulse Blootooth Headphone . I like it very much . I recently found a magnet (5-6 cm long , width of 1-2 cm and height of 2-3 cm) which is kinda powerful lying around in my house . Is it safe to hang my Blootooth headphone on the magnet . Please explain and give details . Thanks guys . Also Is it safe if I place the magnet outside (in the right-side) my Cooler Master Elite 311 case . Thanks in advance guys

So I was thinking of buying this lot of hards drives to make coasters from the platters and get the magnets to use for magnetic stuff http://www.ebay.com/itm/Liquidation-Lot-22-3-5-80-GB-Desktop-PC-3-5-HDD-IDE-EIDE-PATA-Hard-Drives-/201314855821?pt=LH_DefaultDomain_0&hash=item2edf4ceb8d Just thought I would share this idea

So I was getting really annoyed with the front panel on my Corsair C70. Every time I had to clean the filter on the front panel I would have to remove both side panels as well >.< So I decided to use magnets! I mean honestly what problem can't they solve? Magnets Really simple mod, just bend the tabs in The front panel is steel as well as the rest of the case, so just stick on the magnets (I actually glued mine as well with a bit of super glue) The thinner the magnets are the better, my reset button ended up not working so I glued a tiny little washer thing onto it and it works fine now And you're done! Really simple :lol:

I've seen them on power, digital and analog cables. They are pretty much everywhere. What do they do?

So, I had a couple of drives that died on me, well one was technically salvageable but there wasn't really anything worth going through the effort for. So I decided I'd take them apart, because I need more fridge magnets, and the platters are really shiny and... that's probably useful.. For something. Also it's a roundabout way to destroy everything on the HDD if you're really concerned about that sort of thing. So, here we go. First off you'll need a couple of things. A broken HDD, or a not broken one you want to destroy A TX-8 screwdriver or bit or one of those angled keys, (A TX5 screwdriver or bit or one of those angled keys, not sure about this one, I almost never use torx that small) A pair of needle nosed pliers if you don't have the required TX screwdriver for one of the screws A flathead screwdriver About 10-20 minutes of time Now secondly this WILL BREAK YOUR HARD DISK DRIVE, do NOT do this unless you're willing to DESTROY the drive.(Unless you for some reason have a clean room and all the required things to avoid permanently breaking a drive that is.) Now, most of the pictures I took are pretty blurry, I didn't put much effort into that, but I've added annotations where necessary, and there will be text to go with each picture. The first step is to remove a bunch of labels and little stickers that hide the bolts, it's a bit manufacture specific but for the most part the screws should be in about the same place as shown here.(Note: two screws are removed, but it's kinda obvious where they go) This is the point of no return, once you've taken off even one of the screws there are no guarantees that your HDD will ever work again. It's pretty hard to tell from the picture, but all except one of the gray blurs are little TX-8 screws, the only one that isn't a screw is the one that is just below the top right one. Just remove all of these, and the one in the middle has its own explanation. Now, the lid should be ready to pop off, shouldn't be too tricky, just use a flat head screwdriver or a knife or something to help it along, if you can get a good grip you should be able to tear it off with just your hands. Now, once that's off you'll be greeted by something like this So yeah, that's what a HDD looks like on the inside. Those platters are real tough things, it might just be a WD thing, but I've shot a couple of similar drives and unless you hit dead center the platters will absorb a shot from a S&W 1911 .45" ACP and .357" magnum shots from a revolver.(Incidentally so will a stock AMD heatsink, well from the Athlon series at least, haven't shot any other heatsinks..) Now the parts I want, the magnets. You'll, I'd say, definitely need something to pry those suckers loose, afaik they're neodynium magnets and they're damn strong, at least when you stick them together like they are inside a HDD- Trusty old flathead screwdriver should do the trick. Takes a bit of fenangeling but it'll come right off, no screws holding it down. Next up is the end stop for the read/write head. Again the flathead screwdriver comes in handy, or pliers if you prefer that. Should pop right off enabling you to turn the read/write head far enough to the side to lift it off. The black connector is loosely glued in place, or just slightly stuck to the rubber grommet/seal. The final magnet is held down by a single screw, in some older drives and maybe some other manufacturers drives it might be glued in place. (I don't know why this picture has the wrong orientation, it just has for some reason no matter what I do, re-uploaded, changing orientation on photobucket.. Just nope) Now the platters, these are by now completely screwed and unusable for most people without very specialized equipment. So no worries about smearing them with fingerprints and whatnot. The stack is held in place by a central flange which is held down by a bunch of little screws. I think these have a TX size a step down from TX-8, but I managed to get them out by applying a good amount of pressure on the screwdriver. You're gonna get a lot of fingerprints on the platters now, the easiest way to avoid the whole thing to rotate is to just put your thumb on the outer edge of the platter and then undo the screws. Once you've gotten the hold down flange off you can take the first platter off. Now, to get the rest of the platters off you need to remove one more screw, this is a TX-8 head screw.. Not really sure what the bits it's holding in place does, I can only assume it's some kind of anti-wobble device(Again, no idea what's up with the orientation on this picture.. .. It only says TX-8 head bolt anyway) Just for context: Once you've undone that screw you can just turn the entire thing upside down and the platters should come out, it might take a few attempts to get all of them out, but there's nothing holding them in place anymore. Between each platter there's a spacer ring. Now if you're really paranoid you might want to destroy the PCB as well, you can remove this first or last, doesn't really matter, just a few screws holding it in place. All the screws undone, just pull the sucker right off. There. Now you have some really expensive fridge magnets, or a very shiny wind chime, or the option to melt the platters.. Or something, in any case, this is pretty easy and straightforward and anyone can do this if they have the tools for it at least. NOTE: In some drives, (this might just apply to really really old drives not really sure) the platters might be made of glass or ceramics, try not to break them because you'll probably cut yourself real bad and make an incredible mess that will leave you with glass/ceramic shards all over your room for years. AFAIK most modern drives have aluminium platters with a magnetic oxide layer on them, but do be careful. So yeah, the best way to destroy all data on the disk? I'd say take an angle grinder to the platters and grind off all the oxide, or a blowtorch, or ... Something, be creative Or you could just tie a string to it and hang it on a frame and use the platters as a wind chime. Do whatever you want. Also, I'm in no way responsible for anything that happens because you opened your HDD.

I have a few really cool magnets including a Titanfall one that I got from loot crate and I have no were to put them but on my PC case. Naturally I'm very skeptical of doing this because of the problems it can cause but is this just a myth? I mean they have magnetic dust filters and things like that, are a few refrigerator magnets really going to do any harm? Anyway what are your thoughts I'm not sure if this is a good idea or not. (I didn't know were to put a topic like this so i figured general discussion would work)
