$1 POV Display Goes Round and Round
You don’t need much to do a persistence of vision display. A few LEDs and a processor is all it really takes. [B45i] made a simple PC board with five …read more Continue reading $1 POV Display Goes Round and Round

3D Zoetrope Uses Illusion to Double the Frames
Although film and animation have come quite a long way, there’s still something magical about that grandaddy of them all, the zoetrope. Thanks to persistence of vision, our eyes are …read more Continue reading 3D Zoetrope Uses Illusion to Double the Frames
Wiggling Screen and DLP Power This Volumetric POV Display
It seems like the world is ready for a true 3D display. We’ve seen them in sci-fi for decades now, with the ability to view a scene from any angle …read more Continue reading Wiggling Screen and DLP Power This Volumetric POV Display
Big Spinning Disk Makes a Small Color Video Display
The earliest televisions used a spinning disk technology called the Nipkow disk, which is exactly what [Science ‘n’ Stuff] recreated with their Arduino-based mechanical color television (video link, also embedded …read more Continue reading Big Spinning Disk Makes a Small Color Video Display
This POV Clock Combines a Nixie with a Pendulum
Talk about your mixed timekeeping metaphors: there are clocks, and pendulum clocks, and there are Nixie clocks, and persistence of vision clocks. But this is a Nixie pendulum POV clock, …read more Continue reading This POV Clock Combines a Nixie with a Pendulum
Motor-Driven Movement Modernizes POV Toy
Just as we are driven today to watch gifs that get better with every loop, people 100+ years ago entertained themselves with various persistence of vision toys that used the power of optical illusions to make still images come to …read more
Proto-TV Tech Lies Behind This POV Clock
If it weren’t for persistence of vision, that quirk of biochemically mediated vision, life would be pretty boring. No movies, no TV — nothing but reality, the beauty of nature, and live performances to keep us entertained. Sounds dreadful.
We …read more
Edge-Mounted LEDs Make This Spherical POV Look Fantastic
For as many of them as we’ve seen, we still love a good persistence of vision display project. There’s something fascinating about the combination of movement and light creating the illusion of solid surfaces, and there’s always fun to be had in electromechanical aspects of a POV build. This high-resolution …read more

POV LED Staff Takes Art for a Spin
The human body does plenty of cool tricks, but one of the easiest to take advantage of is persistence of vision (POV). Our eyes continue to see light for a fraction of a second after the light goes off, and we can leverage this into fun blinkenlight toys like POV …read more
3D POV Display Has The Shakes
Persistence of vision projects are a dime a dozen, but by adding a third dimension [Madaeon] succesfully created one to stand out from the crowd. Instead of waving around a single line of LEDs, he is moving a 2D grid of them vertically to create a volumetric POV display.
The …read more
