have you considered slowing down the clock? it could be that you are experiencing an instability issue similar to positive feedback, the fix might be as simple as adding a delay in series with the coil drives..

Hey I saw your project at Reno ISEF yesterday! On my way home to Colorado and am at a hotel and thought I'd check the forum and there's your project! Great job!

I have never considered adding lag to the system, it seems to me like a faster feedback loop would always be best. It would be easy to slow it down sometime to test your idea tho, so I will if I have time to.

Thanks! ISEF is always lots of fun.
Can you choose WHERE it levitates? Did you make software to choose the X Y Z coordinates? I can't tell where you got the PCB and the materials.. its so pretty. edit - OHHHH and can the contraption be upside down and still work???? And do you have schematicness?
Yes. The software tells the levitator where 0,0,0 is and I can move the object in real time. I designed the PCB in eagle and had Gold Phoenix make it. The transparent material is polycarbonate that I milled to shape. It will work in any orientation with limited capacity with proper calibration. Sure.

Hello Chris ,
I am a college student from China. You have done many beauitiful thing and I have much interesting about the levitator. I want to make one by myself. Now I have successful to make it floated. But I don't know how to move it . I saw your video that you can move it left , right, front, back also up and down, how to make it ??
I know you have used four hall from your SCH. Two hall was used to detect the X,Y direction And the third hall was used to detect the Z direction. What is the fourth hall used for???
