| Spinning Battery on Magnetic Stirrer |
| (1/2) > >> |
| graybeard:
I bought this IKA C-MAG HS 4 magnetic stirrer at an industrial auction. When I got it home the motor was not working so I took it apart, cleaned it, and lubed the bushings. When I put it back together it worked. Out of curiosity I put a Rayovac AA battery on it and started it and turned it up to high. The battery started spinning rapidly. When I took as video of the spinning battery it appears to be spinning slowly. However it is not. The appearance of the slowly spinning battery is a result of the shutter rate of the video being close to the rotational rate of the battery. I does look "cool." So I decided to share it here. |

Ever since the invention of cinema, audiences have become used to the retrograde artifact in the undersampled wagon wheels in cowboy movies. |

That seems to be a fairly complex method of enhancing battery leakage :-DD |

I see that some Li cells do voltage jumps and realized that movement has a influence, I guess the liquid electrolyte need to wet all surfaces. This treatment might literally shake things up. |

Seems to be a good way to damage the coating on your heater/stirrer plate and get corrosion in the future, assuming you use it for real work.... |
