The PCB I ordered only had the control circuit, so I needed a platform below the board to hold the motor and spinning magnets. I opened the draft from my wooden proof-of-concept, which had accurate footprints for the motor mount and a magnet holder. Last time, I used six small magnets, which were too weak, so I used a pair of large magnets this time. I had 12mm and 1/2" discs in stock and made holders for both.
I cut the parts, made some revisions, and laid them out for a picture when I had a good set. I wanted to show the rest of the group how the "kit" should look. Some parts were inaccurate, and I forgot to include the stir rod, but it was good enough to get an idea.
I assembled two boards, one for the metric magnets and one for the 1/2" magnets. Both operated as I wanted, and it was clear that thicker magnets produced a more reliable stir rod connection.
