That looks pretty cool. At $49 it beats my planned selection. A Ranco Model etc211000000 @ $119.

This is the one that is 2 stage. It will control heat and cooling that way you can have the carboy in the mini fridge to control the cooling side and a heating pad wrapped around...
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...
So, Thanks for your input but I finally solved it. As I thought all along, the problem was the Fan Motor Magnets.
The Hobby Lobby Magnets were strong enough, when stacked, to scramble the North/South Poles of the Motor Magnets causing the Motor to just twitch when power was applied.
The...
One more thing before I buzz off to MicroCenter.
I just spoke to a buddy who just finished his Stir Plate. His 1st Starter is in the Fridge & he's very pleased with the Project.
He bought the identical Bill of Materials from RS & placed the Magnets on a Washer which was Epoxyed directly to...
So, Here's the question of the day:
How do I detiremine if the Fan Side Magnets are too strong?
I'd just as soon not repeat this little exercise as the Centering of the Magnet Spacer/Washer was fairly tediuos. I never got to assemble the wiring to the Off/On Switch, the Potentiometer & the...
Well, What A Pi$$er!!
THe Mule works on all the Wall Warts. It's the Fan. I wouldn't be so steamed if I hadn't laid out $20 for the RS Fan. Don't see how I could take it back as I've hacked the Fan Shroud for clearance. The Mule came from my Desktop & now I have to put it back together again...
djii, I played with the Magnets but only after I had glued the 1/2" Spacer & Washer to the Fan. I had the same thought about de-polarizing the Motors' Magnets. The fan, on 12V, spun too fast & actually slung one of the Magnets into the Void, never to be seen again.
I got these Magnets at Hobby...
coypoo, I have tried a full range of Wall Warts from 3 VDC, 4.5 VDC, & 7.5 VDC as well as the 6, 9 & 12 VDC I mentioned before. All give the same result. Looks like the problem is the Fan. It's a brand new RS 4" per OP Bill of Materials.
I would return it to RS but I've removed some of the...
Wow, Great Thread. I swear I have read this somewhere in the 90 Pages but I can't find it.
I had the fan spinning last night & I was experimenting with different Power Supplies. Today I can't get the Fan to spin at all.
I have the PS wires twisted to the Fan Black & Red wires. The fan...
