5 plate Magnetic stirrer idea. Please help with details.

[VictorHK]

sorry i'm not very technical, could you please help out?

here's what I want to put together (pic below).  I'm going to be using computer fans to spin the magnets so that I can have 5 spots to place my formulas for stirring.  The stirrers I have found are too expensive. With your help I'll be able to build my own, and help others to do the same.

I need to know more about the following things...

Which power adapter should I use? How much DC?
Which Potentiometer I should use for the 5 speed control knobs?
What wiring is best?

I appreciate your help in advance.

Hi Victor,

I don’t want to rain on your parade here but I can see a few problems with this design. The fans are not suitable for this job for a number of reasons, torque, rpm and the loss of balance and the disturbance of the electronic commutating the magnets would create.
