FAV is an audio visualizer that uses ferrofluid. The device's electromagnet interact with the sound being played to make the magnetic fluid dance.

FAV (Fluid Audio Visualizer) - Limited Edition version

<h3>What is Ferrofluid?</h3><p>FAV&nbsp;is a ferrofluid audio visualizer. Ferrofluid is a material first developed by NASA in the 1960s. It has been used for fuel transport in zero-gravity space, spacecraft, and sealing connections in space suits. In modern times, it is used as a damper for high-end speakers, a rotating shaft for motors, and gas sealing. The composition of the magnetic fluid is very fine iron particles and a surfactant coated on it, and base oil. It is a liquid magnetic substance that does not sink because it is so small that it is invisible to the naked eye and is evenly distributed in the base oil due to the surfactant component.</p><h3>Research and Design of FAV</h3><p>It is very tricky to keep the ferrofluid from sticking to the glass bottle. Most of the existing cheap magnetic fluid toys are difficult to use because the magnetic fluid easily sticks to the glass bottle or the magnetic fluid changes after a certain period of time. The glass surface processing technology developed with&nbsp;BurnSlap's&nbsp;proprietary technology prevents magnetic fluid from easily sticking to the glass surface.</p><p>In addition, it does not change easily by using a high-quality magnetic fluid and a transparent liquid developed exclusively for display. Developed in close collaboration with partners with world-class technology.</p><img src="https://wevolver-project-images.s3.us-west-1.amazonaws.com/0.uy6e8yu78sScreenShot2022-09-01at4.44.35pm.png"><p>Magnetic fluid is characterized by being easily changed in a transparent aqueous solution. If you move vigorously like in&nbsp;<strong>FAV</strong>, the rate of degradation increases exponentially.&nbsp;<strong>BurnSlap</strong>&nbsp;has been working with partners to solve these problems.</p><p>In addition, to directly verify this, a specially designed test device was designed and manufactured to test the quality of magnetic fluid in an environment similar to&nbsp;FAV. We are working towards more reliable life expectancy estimates.</p><p>The unique movement of the magnetic fluid created by the&nbsp;FAV&nbsp;creates a more beautiful movement with an independently developed hardware circuit design and software algorithm. In the meantime, the operation and function have been improved through various device and circuit modifications.</p><p>In addition, the electromagnet used as the core component was designed by&nbsp;BurnSlap. This is because it is difficult to make the movement of a fluid attractive with existing off-the-shelf electromagnets. It is made with Burnslap’s proprietary technology designed to harmonize the size and shape of the magnetic field and energy efficiency.</p><img src="https://wevolver-project-images.s3.us-west-1.amazonaws.com/0.itd9325juvgfe61877927903.jpeg"><p>FAV&nbsp;has wireless and wired speaker function. It sounds pretty decent among 5W speakers. It may be not up to the standards of audiophiles, that is why BurnSlap&nbsp;provides an AUX terminal so that excellent speakers from other companies can be used. In addition, the pass-through function is possible through the line input terminal, and you can see the&nbsp;FAV&nbsp;responding to all sounds by connecting a microphone.</p><img src="https://wevolver-project-images.s3.us-west-1.amazonaws.com/0.be6sz3d51ydf9b6923f8e976.jpeg"><p></p><h3>The artist</h3><p><strong>DAKD JUNG</strong>, who developed FAV, is a technology-based installation artist who is active in Korea. Since 2016, he has been creating installation art works using magnetic fluids, mainly focusing on the study of visual expression on the movement of fluids.</p>
