In June 2021, I organized some Mind of a Scientist alums to work on designing and 3D printing electric motors. This is a collaboration between Sonoma State professor Daniel R. Soto, Lawrence Livermore Lab test engineer Jacob Aman, Medtronic mechanical engineer Geoff Orth and Roblox software engineer Alex Katz. Jacob designed a working model using FEMM (Finite Element Method Magnetics). We are working on figuring out how to guide students in tweaking the motor’s design. Much of the work has been done at Chimera makerspace in Sebastopol, but Geoff has also been printing motor parts at Medtronic for us (one is pictured below). We were just awarded a Medtronic grant to purchase more motor parts.

We designed the first motor to be as simple as possible, to demonstrate the principles of electromagnetism. Orchard View science students have built and tested five motors so far. Eventually, the goal is for students to build stuff with the motors they design, such as automated plant experiments and a device for a solar oven to track the sun.

I’ve teamed up with Maker Music Festival founder Joe Szuecs to create a summer camp at Chimera, which will include building motors:
