referring to furtim:
they already have speakers made with neodynum,
check out the bose ACQ 3, infused with ferrofluids.

Canon printer engines use a toner that is made of meltable polyolefin, colored with carbon black and with a bit of magnetic iron oxide inside. The print engine uses a magnetic field to produce a “brush” of toner that wipes an even coat onto the charged drum like a fingerprint kit. The properties of the oxide and the low concentration keep the saturation flux too low for real engineering ferrofluid use.

Remember to use your protectev gear when using the spoon.

If you could get a string of magnet coils under a shallow basin and connect each new ring out from the center to a different range of music tone, and pour the fluid into the center then the fluid would jump up the walls of the basin in relativity (regarding height) to the intensity of the music component tones. Or you could make a plastic box out of plexiglass and put lines of magnets behind it verticaly with one for each range of sound frequency in the music. That way it would behave like the equalizer readout on a stero.

whats th point to ferofluids anyway ?

Jun; I think I value my life better than playing with a hack that can risk my health. The problem with Internet is that everyone become instant experts.

ylim… you need to pay a little more attention to what you’re reading. Wikipedia said, “Some toner is also known to be a carcinogen, but such a large exposure is required that it is generally considered harmless.” So, by and large… No, toner is not carcinogenic

I’m totally liking the idea of using this in a table with a matrix of electromagnets… I wish I had my own place, so I’d have room to work on something like that.

it actually does make cool spikes and stuff but you need a lighter oil(kerosean maybe?) i used what i had here(sae 30) so it isnt as good and for all of the people complaining bout the video length, the ferrofluid itself takes 30 seconds to make or less, the mixing of components basicly

The laser toner is freaking carcinogenic.

I think it would be cool to put a shallow basin of this stuff over a sub or somthing so it would react to the music. Maybe add some uv reactive or glow in the dark dye to get some crazy rave dance hall thing going.

stupid trolls, always trying to steal my precious (time)

packetmonkee, I want the 10 seconds back that it took me to read your troll. Just because this doesn’t make the nice neat spikes that the expensive stuff makes doesn’t mean it’s not useful.

Kevin, thanks for the insight, maybe somebody can improve on this? I like the idea of colored ferofluid.

This would make for a great effect under a glass top table with a matrix of electromagnets under it.

Gay.
Frogz, you owe me 4 minutes and 19 seconds of my life back.

Why is it gay? Not only are you video editing skills exceptionally sub-par, as is your musical taste, but the resulting fluid dosn’t even seem that reactive. Why pay outragious prices for ludicrously small amounts commercially? Because it’s actually useful.

This, however, is not. It’s not even fun.

OK, here is how copier/printer toner work.

Toner is made of two things, carbon black and polystyrene. It is designed to melt into the paper when it goes through the fuser. It is NOT magnetic but will stain if it is heated and will not come out. So if you do get some on you, wash in LOTS of COLD water.

Developer is what people are using to make the Ferofluid. Developer is used to get the toner onto the paper. In modern copers the developer is a synthetic ferride that is shapped into very tiny balls much like a itty bitty golf ball. Depending on how you find the toner/developer mix the ratio of the two will vary.

In some laser printers they use a combination of two into what is called monocomponent.

If you want to make a lot of ferrofluid find a bag of developer on Ebay for a copier. Developer in the silver bag is about 98 percent developer and 2 percent toner. If you use a discarded toner cartridge the ratio might be reversed.

Toner is hydrophobic so it is possible to “clean” developer if you pour it into a waste continer that has water and collect the developer with a magnet. The water will stay on top of the water and the deveoper can be drawn into the water with the magent.

I know all this because I worked on copiers and fax machines for 10 years.

That is all, you can go out and play now.
