I've always wanted to make something like this. I'm curious about parsing the fields into something both pleasing and physically representative of the actual waveform of the music. I'd also like to play around with using the fluid as a driver as well, though I'm sure getting sound out of it would be immensely difficult if not impossible without a horn the size of a barn. As far as I'm aware it has yet to be attempted.

#52I experimented with making a clock using ferrofluid previously. I was inspired by this clock [0] but put off by the price tag. Generally the main issues I found were that it degraded over time and I had real trouble with ferrofluid smearing on the container. Will have to try again now!

The article mentions "Because ferrofluid adheres well to glass, special treatments were required on the glass" but doesn't go into details

#53Amusingly I made a prototype of something similar 4 years ago during university: https://www.facebook.com/1764751847/videos/10202928199083698... It was done to promote the use of Ferrofluid for DataVis rather than a consumer product.
That's pretty awesome - it picks up on way more signal detail than the top project (which is also nonetheless cool).
Yeah, it does feel weirdly out of sync though.

NileRed is one of my favourite chemistry YouTubers, along with NurdRage. There's so much great content on his channels.
When I originally found his channel I thought he might be too young to take any sort of seriously, but he handles being that young pretty well. There isn’t a lot of YouTube nonsense, or begging for subscribers, or jokes that for extremely flat. A model for others I think. Really well done. Although... Explosions and Fire is peak YouTube Chemistry to me!
I would assume that certain amount of basic chemistry is still quite advanced for a non chemist.
If you would create a YouTube channel talking about basis programming language you would also attract plenty of people.
Nonetheless I don't want to lower the value or skill of him.
I'm entertained by it and can't judge his skills.
It still takes a lot to stand in front of a camera and doing what he does but still it could be that a chemist find it boring what he shows.

This kind of reminds me of the Heptapod writing system from "Arrival". I wonder what contributes to the cost -- is it simply because it's unique, or are some of the materials expensive?

Young? He's 29? Were you mistaken or are you implying that 29 is pretty young to be creating self-aware youtube content.
I read it to infer that NileRed looks pretty young for his age, which I think is true.

#58I guess if you made little cells with this fluid, you could make a matrix display.
Re: Ferrofluid display cell Bluetooth speaker
#59Ferrofluid is unstable iirc. I wonder how long this fluid lasts.
Ferrofluid is was used in disk drive motors to seal bearing grease from wandering out so it has reasonable life span of greater than 5 years from my experience
Re: Ferrofluid display cell Bluetooth speaker
#60Oh, I thought the ferrofluid was going to be the speaker. Like plasma speakers [1].
The helium plasma speaker was only good for high frequencies, and needed something else for the bass. Using a heavy liquid for bass might work.
