VoLumen — The Most Advanced Persistence of Vision Display Yet

volumetric

Whoa. We’re just blown away by this new project by [Maximilian Mali] and [Sebastian Haushofer]. It’s a stacked Persistance of Vision display, with 9 layers — effectively creating a Volumetric 3D POV Display.

We recently shared one of [Maximilian's] other projects, The Ripper CNC Machine. As it turns out, the reason he built The Ripper was to aid in the manufacture of his VoLumen project. He’s been designing these Volumetric 3D displays for about 3 years now, with the first iteration called the viSio, capable of 40 fps 3D video without the need for any 3D glasses.

The new and improved VoLumen features 34 micro-controllers, each with 512MB flash memory for storing animation data. In total there are 1024 high power RGB LEDs, which draw a whopping 200W at full load, making it bright, crisp and visible even in direct sunlight. It’s an incredible project that [Maximilian] started when he was only 16 years old.

You have to see the video of this thing in action.

POV Display with an Element of Danger

FZKU6SCHPFZR2KV.LARGE

Persistence of vision displays are always cool, although we must admit this one looks like it could very well explode at high speeds…

Safety concerns aside, this desk fan based display provides a great starting point for learning about making POV displays. It makes use of an old cellphone battery, an ATmega8, some LEDs, Veroboard, assorted wires and solder and of course, a high-speed desk fan.

[shparvez001] also provides the full code on his blog for the project, making it very easy to replicate. Though we might also suggest you keep it small enough that the original fan cage still fits on top.

From an aesthetic point of view, the display looks fine in the dark — but when the lights are on you might get some odd looks. We can see this project being greatly improved by mounting the LEDs through one of the fan blades, and the control electronics on the back side of the other blades. Maybe throw in some wireless charging for the battery while the fan is off too?

Anyway, stick around after the break to see the display in action. If you want a more permanent fan POV try adding display hardware to a ceiling unit.
