Where is pcb diagram?

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

Where did you get your PCBs made?

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?

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 found similar projects and have not been very successful

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!
