Self Stirring Mug using Lego

Step 3 Build a frame

You want to build a frame to support a cup so in this design I built it using Lego pieces. What is important though is that your frame is sturdy enough to hold a cup with liquid and has some clearance for the spinning magnet mechanism. I used a Lego connector that looks like a T shape to attach the magnet onto the gear train. I also used some tape to secure it. When the setup is complete you should be able to place the bar magnet on top and it will lock into place. I chose neodymium magnets because they were strong.

I have a T shaped Lego piece attached to the motor shaft. I taped a strong bar magnet to that piece. Its shown in the second and third picture of step 3. Then the red plate is placed over and a freely moving magnet is placed on top. The magnetic attraction of the bottom magnet causes the top one to spin.
