A fidget spinner is a rotating contraption ideal to toy your time away with persistance of vision. You'll soon be experimenting with displaying names, messages or geometrical pattens or whatever come’s to your mind.
Elektor Labs hosts a POV fidget spinner which will soon be described in Elektor Magazine.

3D-printed housing

On the video below you can catch a glimpse of how  the POV Fidget Spinner will look like in its 3D-printed housing. It has a push-button to turn it on, change display modes and turn it off. A power-off circuit automatically saves the two CR2032 standard coin cells it is powered from. Two? Hu… what about symmetry?
