Luke Richmond i have a hard drive, but no hex screws, a dvd drive but not sure if i should take it apart or save it for a computer as its not to old, and a speaker i cant find.
Holy CRAP!!! These little buggers are frickin' strong! I accidentally got them together (flat side to flat side), and it took a pair of RoboGrip pliers, a screwdriver, a mallet, and 10 minutes to separate them! I made a box to hold them out of an old ring box (with the foam in it) and wrote a "KEEP AWAY FROM ELECTRONICS" note on it! So powerful!
Great vids bud subscribed! Back when i was around 16 or 17 i randomly took apart a big speaker and found a really powerful magnet. had no clue what to do with it at the time but now it holds around 45 takeaway menus to my fridge its great. haha
guys there are some curtains for showers and there are magnets so the curtains dont move and stay in place well use your hnads and rip them out the thing thats protecting them as probably as hard as ripping a baby pillow and you can get 6 magnets and they are strong (thats my way)
I've been doing this since 2000 or so with how people left broken computers for cirb side clean up, but great way to recycle and magnets are always great to have
My mom suggested that i open up old radios or speaker electronics. Yes i did found one behind the speakers and one of those kids guitar with speakers in it. I opened an old one of it and i found another. The magnet is always behind the speaker. Also ty for the info i didnt know which electtronics to get that from
How pounds would you say the magnets from the computer hard drive hold? Also, are there any magnets in old video game consoles like PS2, Xbox, ect that doesn't work. I also have an old scanner that doesn't work
Another cool thing you do with an old CD-Rom drive is use the stator and can from the drive motor and make your own 3 phase brushless r/c model airplane motor.
Lol. Is "niiice" your favourite word? :) I love your videos. Science is actually really fascinating. Keep up the good work. P.S. RU-vid, please include the English spelling of words in your spell checker. "Colour" and "Favourite" are correctly spelt, just not in "US simplified English".
I love pulling apart old electronics and looking for components. You can find all sorts of stuff. A lot of good wires and magnets. The cathode tube on an old TV is fun to smash, btw, it's like a giant light-bulb. Though your mother may not like you doing that in her driveway. (Don't ask) ;)
I was playing with a pair of these from an old hard drive once, and I accidentally chipped through the outer casing of one. Tiny little magnetized metal filings started pouring out of it. Just a warning not to be *too* rough with these.
It's probably best to warn people that it isn't hard to seriously injure oneself with strong magnets. a pair of them can cause all sorts of crushing injuries to digits or even limbs in severe cases. magnet pairs that provide enough force to cause major tissue damage can be found in some more modern computer electronics A good rule of thumb is that if you need special tools to take them apart, be very, very careful about when and where they come back together. A friend of a friend was taking apart a big 2TB hard drive, and once he'd pried the magnets apart, he put one in each pocket. Those magnets found their way back together relatively quickly... apparently it did not end well.
Oliver Rapp I don't know exactly what happened, I was just recounting an anecdote someone else told me (I'm not in contact with them any more, unfortunately) All he said was that the guy put a magnet in each pocket, and they found their way back together. He said "You can imagine what happened", making a gesture inwards from his hips. I'm not sure if the guy just had some bruising, something more serious like a fracture or worse. Sorry I can't be of more help. A quick google search can lead you to examples of people getting fingers and such crushed by strong magnets which sometimes flew distances of around 50cm before they found their mark.
I think that the magnets in the hard-drive are used kinda like brakes, but I'm not sure. As for the one in the speakers, there's an electromagnet that has a rapid electric pulse depending on what's being played, the electromagnet will turn on and off attracting & repelling the neodymium magnet and producing vibrations, which we perceive as sound.
methyl ethyl ketone (MEK) is a solvent found in hardware stores and it works pretty good at breaking down cured adhesives and even two part epoxies. Most of the speaker magnets I see are attached via some sort of glue.
