So here was my big problem (I say was, but it still isn't working out right) I made my stirplate. I used a 12V fan from radioshack and the large project enclosure. I used 9/16 x 1/4" Neodymium magnets from Cynmar. I added a second potentiometer to "give me some fine tuning". Now I have it so that I can keep a slow spin going, with everything cranked all the way down on a 5.9V power supply. But I can't get that slow spin started. It seems that my magnets are restricting the flow of the fan at slower speeds. I can't deal with it today, I"ve been cursing magnetism for the better part of two hours (magnets + epoxy + confined space + fat fingers = HULK MAD!!!)
So now that I have to pry my magnets off and go buy some more epoxy, can anyone suggest a good insulator that I can attach between the fan and the magnets? How tall should it be? If I make it a bit heavier that should slow down the fan speed right? I'm too frustrated to think too hard about it right now....
