Magnetic Stirrer

I made a Magnetic Stirrer that has few parts and is easy to put together. I included a parts list in the pictures, let me know of any questions. It works best with a cup bottom that is flat. Went through Amazon orders, here are some links of parts if needed: WayinTop 3pcs PWM Low Voltage Motor Speed Controller DC 1.8V 3V 5V 6V 12V 2A 1803BK 1803B Adjustable Driver Switch with Speed Control Knob (Pack of 3) https://a.co/d/eCJd0OTPTFE Magnetic Stirrer Mixer Stir Bar, White Color, Stir Rod Magnetic, Laboratory Bar, Stir Plate Bar, Stir Plate Magnet Stick (8 Pieces,30 mm/ 1.18 Inch) https://a.co/d/hVp2VqtTRYMAG Small Strong Magnets, 6 Different Size, 255Pcs Rare Earth Magnets for Crafts, Heavy Duty Neodymium Magnets Round Refrigerator Magnets for Whiteboard, Billboard in Home, Kitchen, Office, School https://a.co/d/1vNsG5PHiLetgo 10pcs Micro USB to DIP Adapter 5pin Female Connector B Type PCB Converter pinboard https://a.co/d/7Fe2zy6
