    Ferrofluid is an interesting substance that is attracted to a magnetic field. While manually playing with a flask of such goo is interesting for a few minutes, GreatScott! had other ideas. His 3D-printed rig arranges a half-dozen custom electromagnets on the side of the flask. This allows an Arduino Nano to control the magnetic field arrangement, and thus fluid movement, with the help of six MOSFETs.

    To make things a bit more interesting, the build integrates an MSGEQ7 chip to analyze sound frequencies, which enables it to bounce the ferrofluid up and down as a three-zone VU meter. The setup also features a strip of addressable LEDs on the bottom for a lighting effect, creating a neat visual complement to your tunes!

    Fetch is a mesmerizing ferrofluid display!

    Arduino Team — May 28th, 2019

    You’ve seen LED matrices, E Ink, CRTs, and likely a variety of other display methods, but chances are you’ve never seen anything like the ferrofluid matrix display by ‘Applied Procrastination.’ 

    This student team from the University of Oslo has created a 252-pixel ferrofluid panel, dubbed “Fetch,” manipulating the inky black substance suspended in a saltwater brine with an array of electromagnets.

    The video below, however, shows only an early 6×6 prototype powered by an Arduino and motor driver. While certainly not as impressive as the yet-to-be-revealed final result, watching the fluid move via this small matrix and even under ‘manual’ magnet control is still incredible. 

    More details on the build—and of course, the large display—is forthcoming, so you may want to subscribe to or bookmark their channel to see what comes next!
