Looks good OP.
Right now I would say is a good time to build a stir plate.
I found this
deal on a computer fan (I was the tipster on Twitter). Yes I tooted my own horn, lol!
Swing by a smoke shop or cigar store and pick up an empty cigar box. Some times they are free, the place near me sells them for $2-3 each.
Pick up a
speed control unit like this one. I purchased this device too, although I wish it was a little better at controlling the RPMs of the fan, but it does the job.
Then get some bolts, nuts and some rubber washers at Home Depot, Lowes or whatever hardware store you have near by. These parts should be less than $5 total.
Magnets, if you want to buy them from the hardware store you can. Or source them from a dead hard drive and they are free (that's what I did).
So after the mail in rebate of the fan, you are probably looking at $15 +/- and some time to assemble everything. The stir bars you can get on Amazon too, but I didn't factor those in at the moment.
