Simple Stirplate

[DRAGGER]

I have decided that in the past I have over engineered most of the projects I get into. This time was different. I only wanted mimimal construction. What i did was purchase a cheap 3.5" hard drive enclosure with power supply and a variable speed fan with controler from newegg.com. Now all that was left is basic assembly. The hard drive case was aluminum and needed a hole cut in it to allow maximum magnetics. I mounted the speed control control into the front panel. glued an old hard drive magnet onto the fan after finding the magnetic center. Photos are below......

Looks nice...seems functional
First time I have seen a single magnet setup for this application...just wondering if the stir bar throws in use?
If I ever get around to doing a stirplate I will probably go for the starburst stir bar


Curious about your part list/links?

It has thrown the bar but only at MAX RPM. It has to pull the vortex to the bottom and cavitate for a while before it throws the bar.....
