Handcrank Toothbrush

 ...at least you don't have to replace the battery.

This is a toothbrush with a head that moves back and forth, connected to a hand crank at the bottom end of the handle. You grasp the toothbrush handle with one hand and cycle the crank with the other, making the toothbrush's head move back and forth.

It's simpler than an electric version would be, somewhat, and at least you never have to replace a battery!

       I don't think the cycles per second will give you what you want . How about the treddle power that was used with the old sewing machines .

       I would prefer to replace battteries every once in a while instead of cranking a toothbrush everyday, but that's just me.

       good for exercise then! but if you predominantly crank with one arm, then you might develop muscles a bit unevenly.

       No, do squeeze motion power, either direct mechanical or indirect thru air pressure or standard springs.

       Very -bakerylike - (+). Would also work well with (link).

       that would be so awkward to use, but if you made the cranking charge a battery, like a hand crank radio, that would actually be a pretty good idea, it would be good for travelling, or just if you don't have enough outlets in your bathroom.
