Ideally you like the starter to be as close to the wort temperature as possibly when pitching. This avoids a time lag as the yeast adjusts.

Thanks! That makes a lot of sense. I suppose you would also want to control temps so there is no temperature "shock" by adding room-temp starters to a warmer wort that is cooling...

I will only be doing the heated version if I get a free temp. controller. I'm still waiting on the free PID, so I'll let you all know what happens...

Just curious...wouldn't the heating have an adverse affect on the electronics? I suppose it wont be an issue since you are using a fan!

Your "Cheap and Easy" Stir Plate:
From Radio Shack, you'll need the following:
7" x 5" x 3" Project Enclosure: Part Number 270-1807 - $5.99
25 ohm 3 watt Rheostat (aka Potentiometer): Part number 271-265 - $3.99
12 Volt DC/30Amp Rocker Switch with LED - Part Number 275-018 - $3.99
Silver Tone Knob - Part Number 274-424 - $2.99

I just caught this thread, I'm glad to see people are still making these things the way I designed it 5 years ago. These are the same parts I spec'd when I came up with the idea of using a computer fan for a stir plate... |

As I asked in another thread, who are you? I honestly am not familiar with your name on here. My parts came from old power supplies at work and I found the closest possible parts at the Shack... post a thread or website?
I have openly admitted that I didn't come up with the idea of a computer fan, however I find it hard to believe that you used the EXACT same parts as me considering that I walked into a radioshack and picked up what I could find that would work with a 6 VDC power supply.
Regardless, congratulations on proving evolution...

So I got mine up and running. Had to make minor tweaks such as bringing the magnet in closer. I installed my fan hanging upside down under the metal plate that came with the project block. This allowed me to use the nuts to bring in the fan really close. I also used a 2 inch octagon stir bar. It makes a HUGE funnel. Perfect. Now I need some yeast to make a starter with this.

Me? Yeah. I was referring to ChillyP's second pic. His vortex is like 1.5" across at the base.
