289 views
A tiny magnet behind the toroid improves performance, as suggested by Tinselkoala. Also a 9000uF electrolytic capacitor mounted close to the circuit helps rev-up the circui...

The rotating head of a VCR has bearings suitable for this kind of motor. A photo-darlington transistor triggers the switching of the toroidal current. It is mounted on the ...

The magnetic field from the winding interacts with a small rare-earth magnet attached to the top of the displacer. A noisy pulse generator has been set up using a relay.

The laminations were cut as required. Four rare-earth magnets drive the alternating magnetic field. A working model would need to have low sliding friction.
