I can't believe it worked the first time!

All this talk about stirplates inspired me to build my own. I hooked it up, plugged it in, and it actually worked! No adjusting or tinkering. I haven't gotten a stir bar yet, but I'll keep y'all updated.


The rare earth magnets that I got at radio shack were a little small, but that is all they had. I'm not quite sure if they are big enough to spin the bar though.


Here is the potentiometer. It is a 5k ohm and it has the same 90% offf 10% sensitive problem, but it works for me.



And here is the stir plate in it's nice little package. I just need to drill a hole in the front to put in the potentiometer.

It's not perfect, but it spins!

Good Job!

Nice job meister...keep us posted.

What kind of stir bar do you guys recommend? I plan to mostly use a 1000mL flask and maybe a 2000mL flask. I might have to put in a resistor because the power is 12V. What ohm resistor should I add if/when I need to?

nice job! Thanks for the help last night. I finaly got mine to work! I have the stir bar thats sold at morebeer. The standard size.

Nice, meister. But can you guys seriously stop posting these bad-ass projects here for me to drool over and then start but never finish? Seriously, my brew shed is packed and my foyer is now 50% full with various pump parts, coolers, SS braids, spigots, coils of copper, etc.

The wife is threatening to build a larger shed.

Oh, hey, also..

Let me be the first to congratulate you on creating the worlds first Christmas tree powered stir plate!

What do you guys think about a 3.7 V power supply? Is that too low? I think the 12 V is too high.
