Hi all! I'm starting to brew alot more lagers and wanted to finally make a stirplate. Yeast is key.
I am attempting to use a 120v fan in my build. I would like to prepare starters of sizes from 1-2 gallons. I assembled this little thing from a 3 speed caged desk fan, and had the brilliant idea of using a standard light dimmer to control the speed. Evidently that wasn't so brilliant as the motor burned out all of a sudden after running for about 10 minutes.
So for now I am scrapping that idea and using a very large powerful DC computer fan, with a variable voltage wall wort. I can now select between 6, 7.5, 9, and 12 volts.
Works great but I still need a larger fan with more juice if I want to stir a small carboy. I need help at this point... I would like to use this fan motor:
Now I need a way to control speed. The dimmer switch is bad. not sure why but it will fry ac motors. Is there something that will let me accurately control the speed of an AC fan? I've seen the 3 speed fan controllers at Home Depot and other hardware stores, but they are a bit pricey and will not allow precision control. Can anyone advise me in this endeavor? Thanks in advance and cheers!
