Is there a good rule of thumb for inches per mL when it comes to stirbars?

just finished my DIY stir plate... Cost $0.00..

Pulled a fan off an old junk computer.
Pulled the magnets out of an old 80gig HD
Cut a power supply from an old cable router that I can't use

Just put the wires together with electricians tape, and hot glued one of the magnets to the middle of the fan. Spins fine when I plugged it in, so I set the fan into a chunk of styro foam that I cut out. When I sit my 2L flask on it with a stir bar, It is nice and "cushy".

I plugged it in, and it worked right off the get go, pulling in a 4"-6" vortex with a 1 1/4" stir bar after about 10 seconds. I suppose this is a bit overkill, but I haven't seen anyone say that a vortex will hurt the yeast.

Easy! Thanks for the idea.

Got mine up and running. Well less than $20. Can't beat it. Got a starter going this morning, and its humming along. Awesome.

I use a 1" stir bar and it seems to work perfectly. 1 or 2 liter (quart) starter. I keep the fan close to the lowest possible speed or it gets thrown.

Here is my stirplate I made using a watch box that I never used.
Spinning a 5L starter with a 2 inch bar also it works with a 2L starter.
At higher than half speed it will throw the bar on the 5L.

Nabbed your idea. Built a prototype in a cardboard Bijoux Terner tie box. Jutting off the lid left the metal/cardboard joint behind so I could wedge the controller into it. Cut a hole out through the side to run the cables out and another for air circulation. Once the magnet is in I'll cover the top with foil to protect it.

I don't think I can overstate how nifty this extension cord is! It goes out quite far and it's probably thin enough to close in a minifridge door.







Gonna need a magnet though. And a stirbar. And a flask.

I'll be looking for less flammable boxes while I get those things. Has anyone heard of stirplates or these USB fans catching on fire from prolonged use?

This is my wife's concern as well.
