Tracking Wasted Time With A Ferrofluid Clock

We know this venture is meant to be about creating a fine-looking ferrofluid clock, and now not in regards to the price of procrastination. But after staring at the video underneath, see when you don’t suppose that procrastination has taken those two scholars additional than anticipated.

We first bumped into [Simen] and [Amund] a number of months in the past when they introduced their ferrofluid venture in a are compatible of “There’s were given to be extra to lifestyles than finding out.” It gave the impression then that construction a handsome, purposeful ferrofluid show could be a brief distraction, however the issues posed proved to be a long way deeper and thornier than both of {the electrical} engineering scholars anticipated. The concept is inconspicuous: include a magnetic fluid between two clear panels and create pixels the usage of an array of electromagnets to transport dots of the fluid round. The implementation, alternatively, was once every other subject, with the ferrofluid itself proved to be the most important impediment. All the formulation they attempted looked as if it would coagulate or degrade over the years and tended to stain the glass. While the degradation was once by no means absolutely looked after, they controlled to paintings across the staining via cautious cleansing of the glass and the usage of a saturated brine technique to fill the container.

Backed via 252 electromagnets and drivers on ten customized PCBs, the video underneath displays the (most commonly) completed panel in motion as a clock. We’re inspired via the smoothness of the actions of every pixel, although there’s slightly of drooping on the backside because of gravity. As for the way forward for the venture, that’s unclear since [Simen] is headed off for a NASA internship. We’re now not positive if that was once regardless of or on account of this procrastination-driven venture, however we congratulate him both means and stay up for listening to extra from either one of them at some point.
