This magnetic stir plate is version #2 utilizing the same box from a previous build where the motor didnt work out. So the box is complete at this point with a simple switch attached taken from a PC power supply. Its just a square wood box so you have not missed much. This covers how I simply swapped out the internals and assembly.

A simple wood box will do or you can utilize a variety of other things you may have around the house to install the motor, which in this case is a simple computer fan. I have made this one to stir the DIY vape juice that I make but it has many other uses as well. Its quick, easy and very useful!

Materials Needed:

A Wooden Box Made To Size (or a plastic project box)

A 12V DC Power supply

A Simple ON/OFF Switch

Glass or Plexiglass To Fit Your Box (if making your own box)

(1) Neodymium Magnet From A Hard Drive

Contact Cement

A Mixing Vessel & Stir Bar

A Little Experience Wiring In A Simple Switch


And thats about it!

    Interesting and looks pretty easy to do. I've always wanted a stirrer for my photo chemicals and now I know how! Thanks for sharing!
