What’s TAOFLEDERMAUS up to today? Well, he just so happens to be test firing some Neodymium shotgun slugs. What’s Neodymium, you ask? It’s essentially producing shotgun rounds that contain crushed up computer hard drive magnets. Should you ever encounter a serious robot problem, these Neodymium slugs should do the trick.

The guys also loaded up some more Bucky Balls, which they’ve fired at the range before. The magnets don’t stick together as well as some might think, but at least the mass of the rounds stayed quite consistent.

  1. Yeah, let’s just find some other dumb shit load into a shotgun shell, because, why not? This is first world time wasting.

  2. Aw, c’mon you spoilsports. These guys are a hoot! Keep ’em comin’ until you do the one with the pork rind round.

  3. Those high grade rare earth magnets only have a small amount of neodymium. The chem. formula is Nd2Fe14B. So there are only 2 atoms of neodymium for every 14 atoms of iron, with a little boron thrown in. With a density of 7.4 gm/cm3 it is a lot less heavy than lead.

  4. Food for thought, magnets don’t actually wipe hard drives. They don’t usually screw with computers beyond CRTs either. I suppose with a strong enough magnet, you could mechanically seize up a hard drive, liquid cooling pump, fans or some other such, but a neodymium slug is about as useful against a machine as a lead one.

    You might, just might, be able to cause some errors in the logic boards with a strong enough magnet in close enough proximity, unlikely to make anyone the new John Connor.

    A fool and his money are soon parted. Ignorance is bliss.

    Also, those powerful little magnets in your hard drives are worth a few bucks. Some say the mounting brackets are Mu-metal but I don’t know for sure. They may be anything from low grade carbon steel to 85% nickel content. I keep em cause they are cool though. I also usually break the magnets removing them from the bracket. Your average 90s CRT can have up to half a pound of nickel in it.

    Ok, thats enough on the scrap metal tangent.

    • “magnets don’t actually wipe hard drives”

      Well they can, but it’s much more than just put one next to a HDD and poof all of your data is gone. If you took a strong neodymium magnet, waved it over it, flipped it over, waved over, and repeat that a few hundred (thousands maybe?) times it’s going to sufficiently randomize the magnetism on the platter to the point where only specialized equipment would be able to read it.

      Remember folks, the only way to truly destroy local data is to incinerate until it’s ash.

      • In the mil we had a hand held degausser for the secret/top secret magnetic storage media; basically a strong-as-f*ck electro magnet you rubbed across the disk.

        • Yep, and that used an AC source for the electromagnet so it was flipping the polarity hundreds of times a second. That’s the key to destroying magnetic remittance.

          Was the degaussing just an intermediate step before incineration? I suppose degaussing and then shredding would be as good as incineration.

    • Strictly speaking, the magnet won’t wipe a hard drive.
      The magnetic field, though, will indeed wipe a hard drive.
      A moving field will do it real well, if it’s strong enough. And it doesn’t really need to be very strong. Remember, it’s a magnetic field that writes the data on the platter, and it’s a magnetic field that changes the data, simply by re-arranging the molecules on the platter surface. So anything that can write to the platter (magnetic field) can also wipe it.

        • In a stationary magnet, yes you need AC, because it’s the moving magnetic field that changes the alignment of the particles in the surface of the platter. In an electromagnet the field builds and collapses, effectively moving the field.
          But, if the magnet is moving, it doesn’t need to be AC, it can be a regular (strong) bar magnet.
          As long as the field moves, it will work. The faster it moves, the better it works. The stronger it is, the better it will work.
          And it needs to be positioned right; we have a strong (but small) magnet in the arm motor (actuator), but it’s positioned at the platters’ edge, so it has little effect on the data storage.

          It’s kinda amazing to me the size of the data track is so narrow in modern drives, the head is so close to the platter surface, “flying’ on a very thin cushion of air, using such a small electromagnet to write the data, that it works at all. And we keep getting higher aerial densities, meaning the tracks keep getting smaller and closer to each other. Just amazing!
