DIY Stir Plate

Hey, I just finished making the Stir Plate as described in the Zymurgy mag.

I did some prep work, but after I assembled all the items it took a grand total of 10 minutes to finish.

Pic 1: Low speed (yes, that is a drill bit on the test flight...my flea hasn't arrived yet!)
Pic 2: High speed vortex
Pics 3 & 4: Innards...

Looks nice...

How much will you be making and selling YOURS for?

Thanks.

Most of my electronics knowledge is hunting down bad wires via wiring harness continuity checks for helicopters and self-propelled artillery (no big deal) and such.

I'm not into this electronics stuff (this and working around batteries scare me) like our desert friend. It took me almost 2 weeks to beg, borrow, steal and hunt down these parts so on my better judgement I believe it's better that I don't offer my services. Sorry.
