I think de-polarize is a bad term. The magnets strong field can possibly interfere with the operation of the motor.
Something I have noticed with PC fans. If the fan blades get pulled up, away from the motor, they start to run rough, or bind. The magnets could be pulling up on the fan rotor, screwing with the shaft/bushing operation. I had a PC fan (on a PC, not a stir plate) that this was a problem with. popping the fan back down in place cured the issue.
Now the question is, Will it have enough power to stir when the Yeast is thick & the viscosity is high? We wont know the answer until Monday/Tuesday. My LHBS was out of 2L Flasks & will get the next shipment then. The Vase works pretty well & holds 1L just fine. It has a wide neck which should allow O2 to get to the surface. But theres little room if the Yeast develops a Krussen (foamy cap).
My next question has to do with the thickness of the Starter & the Neck of the Flask. So, how thick is the Starter after 2 days of stirring?
The flasks Im looking at have a fairly small Neck. Im wondering if the Starter would clog it up as Im trying to pour it into the Fermenter. It would seem that NOT decanting the Starter would reduce that problem, or not. I'm figuring to Slosh it about to thin the settled slurry before pouring it into the Fermenter. I can't see how that would hurt anything. Any comments?
Good grief do you have to tell your entire life story?
It's "krausen".
Have you ever made a starter before? It's not any thicker than that. It's thicker than water but it's not like you're stirring porridge.
You should decant your starter after cold crashing unless you like the flavor of ass in your beer. Starters, especially stirred starters, taste terrible.
My stirrer is speed controlled with the LM317 voltage regulator. Everything stores within itself when done. The coffee container top was a little springy so I added a piece of clear acrylic on top to accommodate heavier payloads. My flask is on order so I borrowed a glass from the kitchen for testing. It should be even better with the thinner flask bottom.
Life Story? Not so much. But since you didn't read ANY of the descriptions of the Problem, I thought a Retelling of the issues was in order.
Oh, & thanks for the Spelling Lesson.
No, I have never made a Starter before, That was the purpose of this Project.
THanks for you input Coypoo It was helpful & not derogatory or condesending.
Later.
The OP said he used a "4 inch" fan. I found a great deal on 80mm fans at Newegg and wonder if these will work. 80mm is just a hair over 3 inches. Anyone else have luck using 80mm fans?
Yes, a >1.57 Watt, 12VDC case fan of 80mm should be strong enough to turn a couple hard drive magnets without any trouble from a 12 VDC power source.
I have (2) 3/4"x 1/4" RE magnets. (YES, they are awesome... they automatically orient themselves to NORTH when stood up on their sieds!!!!!!) I plan to "chair" up the magnets an inch or so with a non ferrous material to keep the magnets from harming the operation of the fan motor. Similar to the "Folders can" did with the PVC
that is legit! my only worry would be if the whole thing is not balanced enough it does not have much base to prevent the whole thing from toppling.
building one today hopefully. Of course living in El Salvador we do not have Radio Shack or any easy way to get most things....

I have white wire from power supply hooked to Supply (right side switch).
I have extra wire from Load to middle prong on Pot.
Red wire from fan on far right prong of Pot.
Still have a yellow wire from fan.

yellow wire doesn't have any use here. Trim it if you want, but you don't need to connect it to anything.

The flasks I’m looking at have a fairly small Neck.
