FAV(Fluid Audio Visualizer) Project

The background of the 

first birth of FAV

Coincidentally, while researching ferrofluids, I discovered an interesting movement and prototyped it to respond to music. Immediately after posting the production video on social media and overseas community websites, many people liked it, and the video quickly spread.

Subsequently, it began to be known by numerous overseas tech review media, and in the meantime, many people around the world showed interest.

I received various questions and messages of support through personal SNS and email. In addition, investors, buyers, designers, marketers,

The musicians were also flooded with requests for collaboration proposals and custom production requests from companies.

To be honest, I didn't know the response would be this good. I was just very surprised and grateful. So, in order to reward them, I have been conducting research and development for a more complete product.

FAV 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.

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 BurnSlap's proprietary technology prevents magnetic fluid from easily sticking to the glass surface.

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.

Magnetic fluid is characterized by being easily changed in a transparent aqueous solution. If you move vigorously like an FAV, the rate of degradation increases exponentially. BurnSlap has been working with partners to solve these problems.

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 FAV. We are working towards more reliable life expectancy estimates.

The unique movement of the magnetic fluid created by the FAV 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.

In addition, the electromagnet used as the core component was designed by 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 Burnslab's proprietary technology designed to harmonize the size and shape of the magnetic field and energy efficiency.

Unfortunately, many copycats appeared 

before BurnSlap's FAV was released.

They may seem easy to copy. 

But, they cannot imitate the results of BurnSlap's unique skill and effort.

This project would never be complete without science, technology, art and philosophy.

FAV has wireless and wired speaker function. It sounds pretty decent among 5W speakers. I know it's not up to the standards of audiophiles.

BurnSlap has been focused on developing audio visualizations like never before. However, developing high-performance speakers is another area of specialization.

So, BurnSlap 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 FAV responding to all sounds by connecting a microphone.

BurnSlap is using Instagram to show how FAV responds to a variety of music genres. If you'd like to see FAV's continuing development, please visit BurnSlap's Instagram account.

I can legally visualize the music of various musicians through Reels.
