Alright, alright, I'm tired of disappointing those of you who want to buy one of my stir plates,
so I'm back in business!
I've made some improvements, ordered the parts, and I should have some completed stir plates within a couple of weeks (LEDs are backordered). Parts are on order for 10 of them, but I don't plan on turning anyone away. If there are more than 10 interested brewers out there, I'll make some more!
I proved that my "new and improved stir plate" is just that tonight. A list of improvements:
"Off the shelf" speed controller (modified "Yuri style" to allow RPMs below 300)
Stronger magnets to keep bigger stir bars in place at higher speeds
Better DC transformer connectors
A 1" stir bar will be INCLUDED
Here's a pic of the two extremes in stirring speed range. That's a 2" stir bar in a full 1 liter flask. Note the one on the left barely has a dimple on the surface.
Now for the bad news: I have to raise the price. I'm going to ask $60.00 (priority shipping to anywhere in the US is INCLUDED). That's still less than half of what a new laboratory supply house stir plate costs!
Thanks again to all of you who have expressed interest! Private message me to work out the details. I won't accept payment until I have a stir plate ready to ship to you.
