Thats a cool idea. What is that? A PVC pipe coupler?

hs0656 said:If your potentiometer is getting really hot, she's wired wrong. You only need 1 wire running in (+), and 1 wire running out (+). The PT doesnt get grounded. If you ran a ground to it, that explains why its hot to the touch. Check your wiring and get back to us...
MI_Craig said:Yep, attached the ground. I'll remove and see if that fixes it. Thanks!
How are people handling magnet placement? With one magnet, my stir bar flies off even at low speed. Two magnets won't allow my fan to spin at all. I'm not sure if I'm getting polarity wrong, or if the single magnet just has to be lifted further from the fan. Right now, my magnets are about 1/4" from the bottom of the glass. Does lifting them away help?
Just curious, was chekcing out stir plate bars at stirbars.com
Any reccs on bar type? I was looking to have the ability to do a gallon stir plate, and a quart sized
Nothing wrong with it. It's just pricier and there is no DIY involved. I built mine for about 5 dollars.
So i assume you hijacked all the parts from around your house, but where did you get the stir stick? The ones I were looking at were like 25$+
I like DIY, but hey, if I can buy it cheaper premade, I might go that route. Hell, I built and electric system for my brewing, I know I could handle the stir plate. Just curious if I "should".
Very cool coalcracker. I probably have most of the stuff from an old PC, but can't get my hands on a cheap stir bar.... We will see what I can dig up.
I cheated. I work for a scientific distribution company. I have ways of getting all sorts of fun stuff for free. This stir plate came from a customer who "traded it in" for a better price on another piece of equipment. The 2L flask came from a sample supply I ordered, and my cost on stir bars is only a few cents.
I have mine on the BTV episode that dropped today. Check it out.

ThisFlomaster said:so after reading the other 200 page DIY thread about using an old computer fan, hard drive magnets, radio shack potentiometer and a random power supply I attempted to build my own. after many a failed attempts and finally getting a working combination using a 18V JBL power supply I found it was spinning to fast for my liking even on the slowest setting.
I saw another thread about this usb fan on amazon.com and said WTF might as well try it out. well let me tell you this works fantastic and is super easy to put together.
