so walker mentioned this in passing in one of his posts. so i decided to look it up a bit. found a lot more information on the morebeer.com forums, so if your lookin thats the place to go. here is my rendition. i had an old tupperware tub layin around that had some green paint dried up in the bottom. thats my case for it. the fan, wires, and power adaptorcame out of my "box o' $hi!". and the control knob came with an oversized heat sink i bought for my CPU a while ago. without further ado here she is. now i gots to get me an erlynmeyer flask.
heres a better shot of the cone. thats the control knob on the left.
and here is a shot of the inurds. (thats okie slang for inside parts)
you cant see the top of the fan, but there are a few magnets glued to the top. the guys on more beer suggest using rare earth magnets. i didnt have any, but i did have some fridge magnets. you know the round ones. then i hacked another pc fan in half, and used it for the spacer between the spinning fan and the lid. works great. now time to get that flask.
Cool! I have enough junk around to make about five of these. Did you spring for an actual stirring rod?

I ended up using the fan I decicated to this for my fermentation fride. Now I have to get a new fan to complete my stirrer.
Last time at the LHBS I ran into a guy who brought one of these homemade stirrers in. He even had some of the magnets left over. I asked him if I can buy 2 of them, but he gave me them for free. This was the only thing I didn't know where to get for cheap.
pc fans are cheap. i only have a 90 mm fan in it, but im thinking about getting a 120 mm fan just so i have more adjustabiliy. the 90 mm pretty much dies if i try to drop the rpms to much. this whole project cost me 3.90 and that was for the stir rod. i had everything else.
i upgraded the stir plate a little bit. first i bought a project box from radio shack, then i added a toggle button. the switch turns it on, the knob adjusts the rpm, and the toggle button will actually adjust from what i call "low gear" and "high gear". there is also a pretty LED. the led is wired in with the push button, so when it is in "high gear" the LED lights up brighter. here she is:
Pretty wicked dude...do a write-up with the parts list for us!

But ditch the airlock and replace it with loosely capped tin-foil. The idea of a stired starter is that it will be constantly aerated. This can't happen when you don't let air into the flask
