This one will not only be one of the popular fidget spinners. It will be a persistance of vision display. While spinning the toy, it will display Names, Messages or animation.
It will work from two CR2032 standard coin cells. It has a push-button to turn it on, change display modes and turn it off. To save batteries it also has a automatic power-off circuit.
Additionally a 3d-printed housing will be made.
This is a work-in-pogress. The picture shows the first prototype made of cardboard. It works, but it will be improved a lot.
The schematics file shows the second approach. I ordered a pcb of this version. It contains some changes to the prototype so development of the software will be made with this one.

More information and a more detailed description will follow...
