    And the guts. I'm no electrician, but it seems to work. I am buying a stir bar tomorrow, so I'll add the tornado pic if it works.

    Yes. From Michaels. But I have issues.

    It won't spin the bar. It throws it around, and that is on the slowest setting. My potentiometer does not crank so low as to stop the fan. Where could my trouble be?

    Plug is 5v output from a cell phone charger.
    Potentiometer is whatever azscoob recommended.
    Fan is 12v 1.5 amp.

    Thoughts?

    throws it around? like the whole box? is it just unbalanced or not centered? if you are talking electrical things, i have no input.

    It throws the stir bar around. I was concerned the magnet wasn't centered, but the fan operates fine on its own. I am not sure how to officially center it. I eye-balled it, looks okay.

    can you mount the box onto something heavy, like a steel plate? i have a few of those if you need one. the torque might just rip the box apart though, but that's still kinda fun.

    The box is fine, it's the stir bar that won't spin properly, it just flies to one side of the flask. It means it might be spinning too fast, but that's just a guess.

    the balance of the stir bar,
    the concentricity of the drive magnets to the fan rotational axis
    and the spacing of the drive magnets relative to the stir bar magnets

    all play a part in how fast you can spin it before it spins off.

    how fast is the fan spinning when you are at the slowest pot setting?
