About a year ago I came across a video showing millimeter-scale levitating robots zipping around a PCB. Since then I’ve had the feeling that “surely, this will be useful for something”.

Last month I finally gave in, started investigating prior art and did a few proof-of-concept experiments. So far this has culminated in moving adorable 1 mm disk magnets around my desk at 0.5 mm precision:

(The “useful for something” part is still under investigation — drop me a line if you’ve got any sweet ideas.)

My notes have too many images / videos / maths for the newsletter; for details check out my research log.

Merry Christmas and have a lovely New Year!
