POV Fidget Spinner

This is the obvious next step to the Fidget Spinner, and the last project involving one. I promise.

Similar projects worth following
I'm sure a lot of us have seen persistence of vision displays before. As I kid I even had an "iTop" which was a top that would spin and write different metrics of the top while it spun. I decided to build this into the latest fad, the fidget spinner.

This was a natural course of the way the Fidget Spinner was going. So I had to do it.

8 LEDs run by a shift register, SAMD21 MCu, hall Latches, magnets, whats not to love?

Has a bunch of fun displays like RPM, number of spins, words, all can be reprogrammed in Arduino IDE.

You have plenty of room on the board...the components that can be...should be 0805...the 0402 is WAY to small for hand soldering...
Either way so absolutely incredible
P.S.  For OSHPark....need "cut out" in the bearing spot, otherwise the fab house will not cut it out

Great project, going to be building a couple up very shortly! Could you add the bearing part no. and supplier to the BoM?

Hello,
This is great project, We event printed our pcbs here locally and soldered it using DigiKey components. But will you please explain excat process of uploading firmware in board. We are trying with USB but port is not detected in Arduino Software.

Can you please add a source for the magnets, or at least dimensions?

  Are you sure? yes | no

Oops! I always forget something. Ill add them to the components, but these are them. https://www.mcmaster.com/#5862K75

if you actually sell this, you will easily become a millionaire

I would say their marketing is bad to be honest. The fact is I don't have the time to make mine as a product or kickstarter right now, maybe in a month or two, but by then it will probably be too late.

In general, not if the maker can't hit the desired consumer price point. The problem with many Kickstarter devices is they come out way to costly for most people, given the new features they have. Thus the market becomes very small, since it's only leading edge tinkerers, with money, that will buy them.

Having a flashlight powered by body heat is cool, that doesn't mean people will pay $80 for it. Plus it has problems working in some situations. 

The biggest market is poor people, not rich people. If you can sell it to poor people, then you will make a lot of money.

This is great, just began my own POV spinner after seeing one my niece had which lit up. Was hoping someone had done a similar project. Looks like it works a charm!
