Please excuse the poor I4 camera, but hey at least it can record somewhat decently.
The tuning is a little off as the capacitors are a little too big, but I had to assure that enough power could run the motor as the power shuttles back and forth between the battery and capacitors.
The switching speed is a little too high too as this doesn't allow the capacitors to fully charge and discharge. Despite this however the power returns back to the battery pretty good and doesn't really consume the battery and kill it like a normal load would. 8 )
