Just a quick post to say that i am almost finished with my DIY (do-it-yourself) magnetic stirrer. It has a nice aluminum frame, but the main part is a fan with an old hard drive magnet taped in the center. The fan will be controlled by a knob so i can adjust it’s speed. It worked great in my testing phase. All that’s left is to wire it up!
Update: Here is a video of it completed: https://keen101.wordpress.com/2013/03/13/my-homemade-diy-do-it-yourself-magnetic-stirrer-is-finished/
