Product Information

A network music streamer is an internet-connected hardware component that streams your favorite digital music using an internet connection. A good network music streamer is easy to use, compatible with several file formats and music streaming services, and will ensure your digital music sounds good to appease both casual listeners and esteemed decibel sages.

If you want both a hydrophobic and oleophobic glass surface, fluoroalkylsilane surface coupling When the iron oxide mixes with the oil, the iron particles stay suspended in the fluid rather than mixing entirely. When you introduce a magnet to the ferrofluid, the magnet pulls the particles apart, forcing the fluid into interesting shapes, peaks, and valleys.

I have not yet tried it but there is a youtuber who has made excellent ferrofluid at home. The broad steps are as follows : Motor oil is the carrier oil that will hold your fluid together. Measure out the motor oil using an electronic scale. Then, pour the oil into a shallow dish made of thin plastic, like a petri dish. [1] X Research source A solution of ~25% distilled water (a.k.a. deionized water) and ~75% of store bought isopropyl alcohol at 91% concentration. That means that ~70% of my solution was actually isopropyl alcohol. I eyeballed the ratio between the water and the isopropyl alcohol, those numbers are likely to not be exactly correct. I'm building on-the-fly braille translators and tactile interfaces by sensing if people are moving the fluid: http://www.artiswrong.com/ffbYou can make brakes with it by putting some fluid between a wheel's axle and hub. The wheel will spin freely as the fluid acts just as a liquid lubricant, but if you apply a magnetic field, you're suddenly putting a lot of friction of the wheel's rotation. CDs and vinyl records are two physical audio formats that some folks swear by, especially when it comes to sound quality. But even the most tenacious audiophiles have come around to the excellent sound quality now available on digital streaming services, so much so that digital audio has become the primary way we consume our music. But with the range of hi-fi setups people have at home, new and old, one of the best ways to bring your digital audio and online streaming services to them is by adding a dedicated network music streamer. Use a magnet to manipulate the ferrofluid. Since iron oxide is magnetic, it will automatically gravitate toward the force of a magnet. Place your magnet underneath the petri dish and move it around. Have fun playing with your ferrofluid! [4] X Research source Ferrofluid is a suspension of small magnetic particles (often magnetite, the magnetic oxide of iron) in a fluid. To avoid the heavy and magnetic particles clumping together or precipitating, they need to be coated in a surfactant. And this only works if the particles are the right size (very small) and you have the right mix of surfactant that works in the carrier fluid (the fluid is usually mineral oil or vegetable oil; alcohols will be a poor choice). To the solution add small amount of Oleic acid and some excess of ammonia which will form ammonium oleate which binds to the magnetic particles and is soluble

After he completed his initial prototype, Jung decided to share his speaker with the world. This, in turn, inspired his possible future plans to bring it to market. “I started making it for fun, but after posting it on my social media, [people were telling me to] ‘shut up and take my money,’” he said. Dispose of ferrofluid like you’d dispose of motor oil. Since ferrofluid is mostly motor oil, it’s considered hazardous waste. For small quantities (like 1 batch), seal it in an airtight container and throw it in the trash. For large quantities (like multiple batches), take the ferrofluid to a hazardous waste facility. [7] X Research sourceI don't have a full answer, but a hint at how to choose your liquid. You want the ferrofluid not to mix with it, so your fluid has to be immiscible with the ferrofluid solvent (or carrier fluid; ferrofluids are colloidal suspensions). In the case of your “FerroFluid EFH-1”, the solvent is a light mineral oil, so you should go with a polar solvent. Now let the particles dry out and then add a few drops of kerosene/petrol to make a concentrated solution. The ferrofluid should be ready now. The good folks at the Univeristat Der Kunste Berlin made a ferrofluid display that can play Nibbles: http://www.digital.udk-berlin.de/en/projects/winter0405/main/hauptprojekt/snoil.html

Amaze your friends and distract yourself at the desk with this astonishing magnetic liquid in a bottle. -Includes one magnet.... Dissolve the soap in water with some acid (sulphuric). The oily substance collected at the top is mostly Oleic acid with stearic acid and linoleic acid. This can be further purified by refrigeration.This is just about the simplest ferrofluid you can make. You'll need two basic materials: magnetic (MICR) ink, and a household oil. I've tried a couple types of oils, and it seemd like a light lubricating oil works best, but any cooking oil will work fine, as well. The amount of oil you have is pretty much the amount of ferrofluid you'll get out--about 50mL is good for starters, but feel free to make as much as you want. This was the purification process. Note that you can also use paint thinner in place of petrol and isopropyl alcohol in place of Acetone. Keep collections to yourself or inspire other shoppers! Keep in mind that anyone can view public collections—they may also appear in recommendations and other places. Add some isopropyl alcohol to the glass container. Then add some (or all) of your ferrofluid to the container. Then add some water to bring your isopropyl alcohol concentration to about 70%. Next, use a magnet to settle the ferrofluid to the bottom and then remove the magnet. If your ferrofluid has little bits that are floating, then you need to add more water. If your ferrofluid looks too stringy then I would add more alcohol. When I was done the ferrofluid had zero staining, like you see in the videos online, except for in a few spots. I think for better results I would need a higher quality glass container.

For rare earth magnets cheap, hit up a two way radio shop. I'm constantly replacing speakers in portables (uh, walkie-talkies to those not in the industry). The, more or less, dime sized neo magnets are what I use to hold a lot of tools suspended from the four foot fluorescent light over my repair bench. Drivers, wrenches, a hammer... They're small but powerful. Since finding out about ferrofluid, Jung has used it in multiple pieces of art — including an impressive ferrofluid “ Pataphysical Pond,” in which the ferrofluid spreads out like a live oil spill or an ever-shifting Rorschach test. The idea for the speaker came to him when he was listening to music while playing with a ferrofluid display cell he had built. Absentmindedly, he manually began timing the electromagnetic pulses to match the music he was hearing. Inside the speaker shell are tripleupward-firing speaker drivers, a Bluetooth module for connecting with an audio source, and a compact amplifier. There’s also a glass bottle containing the ferrofluid, some LEDs for illuminating it, and a mounted electromagnet, controlled via Arduino Nano, whichcoaxes the ferrofluid into reacting to the music played.Glass bottle, ideally with flat sides. If you have a round bottle you may not be able to see the ferrofluid due to diffraction. Before anyone suggest to buy online, I would like to make it myself and learn the whole process VS store bought item. Dissolve the Oleic acid coated particles in petrol/kerosene and then keep the beaker over a big magnet to precipitate the unwanted big particles. Then Decant the useful Oleic acid coated particles which stayed in the solution
