Throw your Povard in the air. Then wave it like you just don’t care! Everyone will be able to read your message loud and clear. The Povard is a large hand held POV device that is built onto a very cool laser cut and etched acrylic bezel. A POV “tricks” your eyes into seeing a full image when only part of the image is visible at one time. This effect is called the “Persistence Of Vision.” This is the way the Povard works. As you move the Povard you will see one slice of each letter at a time. Your brain assembles all the slices together for you to be able to see a complete word or image.

Note: An Arduino is required (and not included) for programming the Povard

Maker Shed

The Maker Shed is brought to you by Maker Media, the makers of MAKE Magazine, the Maker Faire, and much more.

Launched originally as a source for back issues of MAKE Magazine, the Maker Shed expanded rapidly to meet the demand for ‘projects in a box,’ otherwise known as kits. Now we have a little bit of everything for makers, crafters, and budding scientists, from Arduinos to sock monkeys to chemistry sets .

    I love the look of the POVARD, sweet project. What would make it even sweeter is an accelerometer that can sense direction changes and reverse the light sequence. That way you can get a message to hang in the air as you wave the unit back and forth.

    A few years ago I built a version like that on a basic stamp. See

      That’s a great idea. I wonder how hard it would be to implement. If the Arduino was on the Povard it would really easy. A simple wire “switch” would be cheap too.

    Thanks Marc,

    Should be a snap, but its hard to tell without a schematic. Where are the schematics?
